Municipal solid waste: A strategic resource sajjalp
A largely rural country, with only 18% of the population living in urban areas, Nepal is urbanizing rapidly with urban population growth rates of up to 7%. With a population growth rate of about 4% per year, the municipalities of Kathmandu Valley are facing the unprecedented challenges of rapid urbanization and modernization on a metropolitan scale. The average rate of municipal solid waste (MSW) generation is 341.63 gm per capita per day in five municipalities (Kathmandu, Lalitpur, Bhaktapur, Thimi and Kirtipur) of Kathmandu Valley. The increasing and unmanageable waste volume is a major concern for all the municipalities. In Kathmandu Valley most of the MSW is land-filled, leading to a significant pressure on the environment. The truth is very little is recycled. In this paper, the basic indicators of MSW are analyzed: generation per capita per day, total waste generation, and waste generation from household, commercial and institutional activities etc. The municipalities of Kathmandu valley are focusing on sweeping the street,
collecting and transferring the waste to the landfill rather than minimizing the waste. The important priorities to consider MSW as a strategic resource are: reduction of waste at source, re-use, compost, recycle and recovery which will minimize the disposal volume and increase the life of landfill.

“Prediction of industrial solid waste with anfis model and its comparison wit...Manoj Kumar Tiwari
This paper is an attempt to estimate the quantity of Industrial solid waste (ISW) that can be generated in the Durg-Bhilai Twin city (DBTC), C.G, India from 2010 to 2026. The prediction of Industrial solid waste generation plays an important role in solid waste management. Yet achieving the anticipated prediction accuracy with regard to the generation trends facing many fast growing regions is quite challenging. In addition to the population growth and migration, underlying economic development, household size, employment changes, and the impact of waste recycling would influences the solid waste generation interactively. The development of a reliable model for predicting the aggregate impact of economic trends, population changes, and recycling impact on solid waste generation would be a useful advance in the practice of solid waste management [7]. The four input variables considered in the ANFIS model to predict ISW in the study area are Population of Durg-Bhilai Twin City (DBTC), ISW generated at DBTC, Percentage of urban population of the nation and GDP per capita of the nation. ANFIS is used in function approximation, time series prediction, and control [1] [2] [4]. In the absence of the adequate past data on waste generation rates, it is extremely difficult to decide upon the methodology to make any kind of prediction for the future. Hardly any primary survey studies have been made in the study area, which indicates the actual waste quantum generated. As a result, except for data points from 1961 to 2001 population based on census , Industrial solid waste generated at DBTC from 1961 to 2001 and 2009 based on the data collected from the DBTC. The estimates of waste quantum for period from 2010 to 2026,shows that if the growth of industrialization and growth of percentage increase in per capita waste generation, are considered as per the nation projections, the ISW in the study area can be expected by ANFIS model using MAT Lab Version 7.8.0.347 as around 88,980 MT per year in DBTC by 2026. Due to the important role of Waste Generation (WG) prediction in ISWMS, a proper model was developed using ANN and ANFIS models [24][26] [30]. In this study, first WG in DBTC was predicted using ANN and ANFIS models; also uncertainty analysis was used to determine the uncertainty of two hybrid models.

A study Report on Implementation of GIS in Solid Waste ManagementAM Publications
Increasing human population and economic development and urbanization has resulted in generation of huge quantities of municipal solid waste (MSW). It involves many activities like collection, transportation and disposal of wastes. There is tremendous amount of loss in terms of environment degradation, health hazards and economic descend, due to direct disposal of waste. It is better to segregate waste at initial stages where it is generated. Planners are thus forced to consider alternate and available means of disposal, especially by minimizing damage to the ecosystem and human population. GIS has proved to be boon to such planners by visualizing the real solid waste situations and facilitating route analysis through mapping. A Geographic Information System (GIS) is a computer system for capturing, storing, checking and displaying data related to positions on Earth’s surface.

Abstract Community solid waste management is an important issue in India due to the inherent challenge it is posing as urbanization is on the rise. Currently in India as well as in many urban cities and its activities the population growth has resulted in an increased community solid waste generation rate. Bangalore is the largest city and business capital of Karnataka state. The population of the city as per the 2011 census is 8,443,675 with the total number of houses 2,101,831 A part from infrastructural development going on for sustainable development MSW management should also be taken care off. In the present study community solid waste management collection, transportation and disposal cost plays an important role about 65-75% of total cost. Hence, in Bangalore city four wards were selected to study the community solid waste management system and also optimizations of routing system, collection procedure, transport and transfer activities. Geographical Information System is a device introduced to plan for waste management and also quickly implemented to overcome community solid waste management limitation. This paper attempts to analyze the existing status of transportation of location of municipal waste along with the various secondary routes followed for the solid waste collection of selected wards of Bangalore under BBMP. In the present study, using Arc GIS, a proper optimizing the waste transportation routes and segregation of waste for efficiency in distance travelled and time taken. The clusters are made by taking the time into account, which may be plus or minus the total working hours for the day. In addition, a simple optimal routing system is proposed to achieve the minimum cost/distance/time efficient collection and transport path for community solid waste management as well as social and environmental implications. Key words: community solid waste management, GIS, route optimization, transportation.

Solid Waste Management System: Public-Private Partnership, the Best System fo...IJERA Editor
Solid waste management (SWM) is a major public health and environmental concern in urban areas of many
developing countries. Nairobi’s solid waste situation, which could be taken to generally represent the status
which is largely characterized by low coverage of solid waste collection, pollution from uncontrolled dumping
of waste, inefficient public services, unregulated and uncoordinated private sector and lack of key solid waste
management infrastructure. This paper recapitulates on the public-private partnership as the best system for
developing countries; challenges, approaches, practices or systems of SWM, and outcomes or advantages to the
approach; the literature review focuses on surveying information pertaining to existing waste management
methodologies, policies, and research relevant to the SWM. Information was sourced from peer-reviewed
academic literature, grey literature, publicly available waste management plans, and through consultation with
waste management professionals. Literature pertaining to SWM and municipal solid waste minimization,
auditing and management were searched for through online journal databases, particularly Web of Science, and
Science Direct. Legislation pertaining to waste management was also researched using the different databases.
Additional information was obtained from grey literature and textbooks pertaining to waste management topics.
After conducting preliminary research, prevalent references of select sources were identified and scanned for
additional relevant articles. Research was also expanded to include literature pertaining to recycling,
composting, education, and case studies; the manuscript summarizes with future recommendationsin terms
collaborations of public/ private patternships, sensitization of people, privatization is important in improving
processes and modernizing urban waste management, contract private sector, integrated waste management
should be encouraged, provisional government leaders need to alter their mind set, prepare a strategic, integrated
SWM plan for the cities, enact strong and adequate legislation at city and national level, evaluate the real
impacts of waste management systems, utilizing locally based solutions for SWM service delivery and design,
location, management of the waste collection centersand recycling and compositing activities should be
encouraged.

Life cycle cost analysis of overlay for an urban road in bangaloreeSAT Journals
Abstract
Pavements are subjected to severe condition of stresses and weathering effects from the day they are constructed and opened to traffic
mainly due to its fatigue behavior and environmental effects. Therefore, pavement rehabilitation is one of the most important
components of entire road systems. This paper highlights the design of concrete pavement with added mono fibers like polypropylene,
steel and hybrid fibres for a widened portion of existing concrete pavement and various overlay alternatives for an existing
bituminous pavement in an urban road in Bangalore. Along with this, Life cycle cost analyses at these sections are done by Net
Present Value (NPV) method to identify the most feasible option. The results show that though the initial cost of construction of
concrete overlay is high, over a period of time it prove to be better than the bituminous overlay considering the whole life cycle cost.
The economic analysis also indicates that, out of the three fibre options, hybrid reinforced concrete would be economical without
compromising the performance of the pavement.

Influence of reinforcement on the behavior of hollow concrete block masonry p...eSAT Journals
Abstract
Reinforced masonry was developed to exploit the strength potential of masonry and to solve its lack of tensile strength. Experimental
and analytical studies have been carried out to investigate the effect of reinforcement on the behavior of hollow concrete block
masonry prisms under compression and to predict ultimate failure compressive strength. In the numerical program, three dimensional
non-linear finite elements (FE) model based on the micro-modeling approach is developed for both unreinforced and reinforced
masonry prisms using ANSYS (14.5). The proposed FE model uses multi-linear stress-strain relationships to model the non-linear
behavior of hollow concrete block, mortar, and grout. Willam-Warnke’s five parameter failure theory has been adopted to model the
failure of masonry materials. The comparison of the numerical and experimental results indicates that the FE models can successfully
capture the highly nonlinear behavior of the physical specimens and accurately predict their strength and failure mechanisms.

Evaluation of punching shear in flat slabseSAT Journals
Abstract
Flat-slab construction has been widely used in construction today because of many advantages that it offers. The basic philosophy in
the design of flat slab is to consider only gravity forces; this method ignores the effect of punching shear due to unbalanced moments
at the slab column junction which is critical. An attempt has been made to generate generalized design sheets which accounts both
punching shear due to gravity loads and unbalanced moments for cases (a) interior column; (b) edge column (bending perpendicular
to shorter edge); (c) edge column (bending parallel to shorter edge); (d) corner column. These design sheets are prepared as per
codal provisions of IS 456-2000. These design sheets will be helpful in calculating the shear reinforcement to be provided at the
critical section which is ignored in many design offices. Apart from its usefulness in evaluating punching shear and the necessary
shear reinforcement, the design sheets developed will enable the designer to fix the depth of flat slab during the initial phase of the
design.

Abstract
The development of watershed aims at productive utilization of all the available natural resources in the entire area extending from
ridge line to stream outlet. The per capita availability of land for cultivation has been decreasing over the years. Therefore, water and
the related land resources must be developed, utilized and managed in an integrated and comprehensive manner. Remote sensing and
GIS techniques are being increasingly used for planning, management and development of natural resources. The study area, Nallur
Amanikere watershed geographically lies between 110 38’ and 110 52’ N latitude and 760 30’ and 760 50’ E longitude with an area of
415.68 Sq. km. The thematic layers such as land use/land cover and soil maps were derived from remotely sensed data and overlayed
through ArcGIS software to assign the curve number on polygon wise. The daily rainfall data of six rain gauge stations in and around
the watershed (2001-2011) was used to estimate the daily runoff from the watershed using Soil Conservation Service - Curve Number
(SCS-CN) method. The runoff estimated from the SCS-CN model was then used to know the variation of runoff potential with different

Abstract The nonlinear Static procedure also well known as pushover analysis is method where in monotonically increasing loads are applied to the structure till the structure is unable to resist any further load. It is a popular tool for seismic performance evaluation of existing and new structures. In literature lot of research has been carried out on conventional pushover analysis and after knowing deficiency efforts have been made to improve it. But actual test results to verify the analytically obtained pushover results are rarely available. It has been found that some amount of variation is always expected to exist in seismic demand prediction of pushover analysis. Initial study is carried out by considering user defined hinge properties and default hinge length. Attempt is being made to assess the variation of pushover analysis results by considering user defined hinge properties and various hinge length formulations available in literature and results compared with experimentally obtained results based on test carried out on a G+2 storied RCC framed structure. For the present study two geometric models viz bare frame and rigid frame model is considered and it is found that the results of pushover analysis are very sensitive to geometric model and hinge length adopted.

Abstract
Depletion of natural resources and aggregate quarries for the road construction is a serious problem to procure materials. Hence
recycling or reuse of material is beneficial. On emphasizing development in sustainable construction in the present era, recycling of
asphalt pavements is one of the effective and proven rehabilitation processes. For the laboratory investigations reclaimed asphalt
pavement (RAP) from NH-4 and crumb rubber modified binder (CRMB-55) was used. Foundry waste was used as a replacement to
conventional filler. Laboratory tests were conducted on asphalt concrete mixes with 30, 40, 50, and 60 percent replacement with RAP.
These test results were compared with conventional mixes and asphalt concrete mixes with complete binder extracted RAP
aggregates. Mix design was carried out by Marshall Method. The Marshall Tests indicated highest stability values for asphalt
concrete (AC) mixes with 60% RAP. The optimum binder content (OBC) decreased with increased in RAP in AC mixes. The Indirect
Tensile Strength (ITS) for AC mixes with RAP also was found to be higher when compared to conventional AC mixes at 300C.

Abstract
Municipal solid waste management system (MSWMS) includes MSW generation, storage, collection, transfer and transport,
processing and disposal. The planning of an optimal MSWM strategy requires a reliable tool for predicting the amount of municipal
solid waste (MSW) that is likely to be produced. The MSWMS is a complex, dynamic and multi-faceted system depending not only on
available technology but also upon economic and social factors. Computer models are of great value to understand the dynamics of
such complex systems. Therefore, in this study a system dynamics (SD) computer model has been used to predict MSW generated,
collected, disposed, recycled and treated capacities, and to estimate the electricity generated from MSW and to predict the fund
required for MSWM in Delhi during 2006 and 2024. It is expected that the per capita generation rate will be 0.61 kg/day and the
compost production rate will be 342 thousands in 2024. The electrical energy generation potential from various MSW treatment
methods will be 302275.3 Mwh and the projection revenue produced from different facilities will be 2068.6 (million Rs.) and this
revenue can cover all the costs required for these facilities in 2024.
Keywords: solid waste management, system dynamics, modeling, Delhi.

1. INTRODUCTION
The state of Delhi with a population of approximately 15
millions is one of the biggest metropolises of the world. With
increasing urbanization and changing lifestyle, the amount of
MSW has been increased rapidly, and the composition has
been changing. The people of Delhi generate millions of tones
of MSW yearly and the MSW quantity is increasing with the
population growth. The flow network of MSW stream in Delhi
is divided into three main sets: generation sources,
intermediate facilities (composting and recycling) and ultimate
disposal (landfills). The collection and disposal of MSW have
been entrusted to three municipalities i.e. Municipal
Corporation of Delhi (MCD), New Delhi Municipal
Corporation (NDMC) and Delhi Cantonment Board (DCB).
The Conservancy and Sanitation Engineering (CSE)
Department of MCD is responsible for MSWM in most of the
State running a comprehensive operation of street cleansing,
MSW collection, transportation and disposal at landfill sites,
repair and maintenance of the MSW storage facilities,
dustbins, transportation vehicles involving a large number of
staff and mobile equipment and plant. The municipal
corporation often depends on the vehicle trips record to
estimate the waste quantity. This does not give the actual
picture of waste generation. Studies carried out by MCD to
estimate the quantity and characteristics of MSW during 2005
and it indicated that Delhi generates about 8567 tons of waste
every day. About 6554 tons (i.e., 76.5 % of total waste
generated) is collected from 2400 secondary collection points,
however, 2000 tons (i.e., 23.5 %) does not reach the municipal
stream. This unaccounted waste is either recycled by rag
pickers at various locations or left unattended at various stages
of waste generation, collection and transportation wherever
services are not provided properly. The per capita generation
of MSW in Delhi is approximately 0.5 Kg/capita/day (MCD,
2006; NDMC, 2006; MCD, 2005; NDMC, 2005; Sharholy et
al., 2005; MCD, 2004).
Delhi has been disposing of its MSW in three sanitary landfills
namely, Okhla, Gazipur and Bhalswa; these landfills are mere
dumps without proper liners and leachate collection systems.
For treatment and processing of MSW, there are three
compost plants two in Okhla operated by MCD and NDMC
and one in Bhalswa operated by a private developer (M/s
Excel Industries Limited). Recycling of MSW is a widely
prevalent activity in Delhi and an extensive network of
informal and formal stakeholders are involved in this process.
The number of rag pickers in Delhi is ranging from 80,000 to
100,000 and each one collects around 15 kg of waste
everyday, it reduces the load for treatment and disposal by
1200-1500 tons per day. Recycling units in Delhi work both in
formal and informal sectors and geography spread across
Delhi and it is generally done in a dirty and unhygienic
manner (Sharholy et al., 2007; CPCB, 2004).
System Dynamics (SD) is a methodology for analyzing
complex systems and problems over time with the aid of
computer simulation software. It deals with internal feedback
loops and time delays that affect the behaviour of the entire
system. What makes using SD different from other approaches
for studying complex systems is the use of feedback loops,

stocks and flows. These elements help describe how even
seemingly simple systems display baffling nonlinearity.
Talyan et al. (2007) and Chaerul and Tanaka (2007) presented
a detailed description about SD and its applications. Computer
software is used to simulate a SD model of the situation being
studied. The mathematical mapping of a SD stock-flow
diagram occurs via a system of differential equations, which is
solved numerically via simulation. Nowadays, high-level
graphical simulation programs (such as i-think, Stella,
Vensim, and Powersim) support the analysis and study of
these systems. The real power of SD is utilised through
simulation. Although it is possible to perform the modeling in
a spreadsheet, there is a variety of software packages that have
been optimised for this. The steps involved in a simulation are:
Define the problem boundary
Identify the most important stocks and flows that
change these stock levels
Identify sources of information that impact the flows
Identify the main feedback loops
Draw a causal loop diagram that links the stocks,
flows and sources of information
Write the equations that determine the flows
Estimate the parameters and initial conditions. These
can be estimated using statistical methods, expert
opinion, market research data or other relevant
sources of information.
Simulate the model and analyse results
SD modeling has found application in a wide range of areas
and it has been used to address practically every sort of
feedback system, including population, business systems,
ecological systems, social-economic systems, agricultural
systems, political decision making systems, and environmental
systems (Dyson and Chang, 2005). The policy makers and
researchers have extensively used SD approach for every sort
of complex and dynamic system such as political decision-
making systems (Nail et al., 1992), environmental impact
assessment (Vizayakumar and Mohapatra, 1991; Vizayakumar
and Mohapatra, 1993), global warming and greenhouse gas
emissions (Sterman et al., 2002; Anand et al., 2005), water
resource planning (Ford, 1996), environmental planning and
management (Vezjak et al., 1998; Wood and Shelley, 1999;
Abbott and Stanley, 1999; Guo et al., 2001), ecological
modeling (Wu et al., 1993; Saysel and Barlas, 2001), value of
water conservation (Stave, 2003), the consequences of dioxin
to the supply chain of the chicken industry (Minegishi and
Thiel, 2000), modeling of a shallow freshwater lake for
ecological and economic sustainability (Guneralp and Barlas,
2003), the impact of environmental issues on long-term
behavior of a single product supply chain with product
recovery (Georgiadis and Vlachos, 2004), sustainability of
ecological agricultural development at a county level (Shi and
Gill, 2005), environmental sustainability in an agricultural
development project (Saysel et al., 2002), regional sustainable
development issues (Bach and Saeed, 1992) and SWM
(Mashayekhi, 1993; Sudhir et al., 1997; Karavezyris et al.,
2002; Themelis et al., 2002; Dyson and Chang, 2005; Sufian
and Bala, 2007; Talyan et al., 2007 Chaerul and Tanaka,
2007).
Mashayekhi (1993) explored a dynamic analysis for analyzing
the transition of landfill method of disposal to other forms of
disposal for the city of New York. Sudhir et al. (1997)
employed a SD model to capture the dynamic nature of
interactions among the various elements of urban SWMS in a
typical metropolitan city in India. The model has provided a
platform for debate on the potential and systemic
consequences of various structural and policy alternatives for
sustainable SWM. Karavezyris et al. (2002) developed a
methodology to incorporate qualitative variables such as
voluntary recycling participation and regulation impact
quantitatively to forecast SW generation. Themelis et al.
(2002) reported that the heating values of the different types of
wastes decrease as the moisture content increases. Dyson and
Chang (2005) emphasized the capability of SD for the
prediction of SW generation in an urban setting with a high
economic growth potential. The authors developed SD models
based on the simulation of five different combinations of
factors that influence SW generation. The factors include: total
income per service center; people per household; historical
amount generated; income per household and population.
Sufian and Bala (2007) developed a SD computer model to
predict SW generation, collection capacity and electricity
generation from SW and to assess the needs for SWM of the
urban city of Dhaka, Bangladesh. Talyan et al. (2007)
developed a SD approach to quantify the methane emission
from MSW disposal in Delhi. Chaerul and Tanaka (2007)
developed a SD approach to determine the interactive relation
among factors in hospital waste management system in a
developing country.
2. METHODOLOGY
Initial step of SD modeling approach is the identification of
problem followed by development of dynamic hypothesis
explaining the causes of the problem. The dynamic model is
converted to the causal loop diagrams or stock flow diagrams,
which are based on the interlinkage of different components
associated within the system. This model formulation is
normally designed to test a computer simulation model with
regard to the alternative policies within the system. In SD
modeling, simulations are time dependent. To develop SD
models, the relevant study material can be found in the
literature (Forrester, 1961; Forrester, 1968; Randers, 1980;
Richardson and Pugh, 1989; Mohapatra et al., 1994). As far as
SWM is concerned, the prediction of waste generation plays
an important role in the management system. Traditional
forecasting methods frequently count on the demographic and
socioeconomic factors on a per-capita basis. In order to
forecast the MSW generation of a complex waste management
system, a SD model has been proposed. In this study

Powersim Studio Academic 2005 software was used to
support the analysis and study of MSWM system in Delhi.
3. DEVELOPMENT SYSTEM DYNAMICS
MODEL FOR MSWMS IN DELHI
3.1. Explanatory Model - Causal Loop Diagram
The causal loop diagram has presented in Fig. 1 depicts the
relationships between the essential elements of MSWMS in
Delhi and the influencing factors. An important issue is that
the amount of MSW generation increases with the increase in
population and growth economic (GSDP and per capita
income). If the MSW generated is disposed of in an
inappropriate way it will negatively affect the environment
and cause environmental problems then the funds required for
managing this waste will be increased causing deficit in the
municipal budget. Applying an integrated MSWMS
(IMSWMS) can minimize the environmental effects. The
environmental problems have a strong influence on the three
main factors: legal, economic and social patterns. Firstly, the
legislative rules set up goals and standards to regulate the
impact of the different treatment technologies. Thus, goals and
standards contribute to the establishment of IMSWMS through
MSWM plans (MSWMP). Secondly, the environment
problems lead to economic burden for municipalities,
governments and indirectly for the general public as well. In
order to decrease further the environmental problems and to
create revenues and fund for MSWM, a tax system is
introduced. This also stimulates the IMSWMS by promoting
the appropriate treatment methods, which can also help in
covering the deficit in the municipal budget. In addition,
increasing public awareness about different problems
associated with MSW may help in source segregation and
reduction, thus reinforcing the IMSWMS.
3.2. A System Dynamics Model for the Existing
MSWMS (2001-2006)
The baseline scenario is simulated for the existing conditions
of MSWMS in Delhi between 2001 and 2006. The baseline
scenario can be considered as reference scenarios to which
other scenarios can be compared. The initial population of
Delhi for the year 2001 was 13,850,507. The decadal average
population growth rate for 1991-2001 was 3.93 %, which will
rise with the compounded net annual growth rate of 2.9 % for
the period 2001-2006 (Census of India, 1991; Census of India,
2001; MCD, 2004; DoES, 2006). Data on Gross State
Domestic Product (GSDP) for Delhi was colleted for the
period 2001-2006 and the annual growth rate and the per
capita GSDP were estimated for the same period. The per
capita MSW generation rate was taken as 0.45 kg/day in 2001
(MCD, 2004; CPCB, 2004). The relationship between the per
capita GSDP and the per capita MSW generation rate was
estimated and then the per capita MSW generation rate was
determined. The population and per capita generation rate can
give the amount of MSW generated for the city. The
recyclables fraction of waste ranges from 13-20% (Sharholy et
al., 2007; MCD, 2005; MCD, 2006; NDMC, 2005; NDMC;
2006). The initial value of recyclables fraction was taken as
15% for the year 2001. This fraction will grow at rate of 0.005
yearly. It is assumed that the recycling efficiency is 50%. The
recycling system involves the formal sector, the municipal
body and a large informal sector that consists of many actors
such as rag pickers, itinerant buyers, small scrap dealers and
wholesalers, which are responsible for recycling of MSW. The
informal sector’s involvement in recycling of MSW is making
it highly efficient. Using the previous data the amount of
recycled waste can be estimated, then the amount of collected
MSW using 80% the collection efficiency and the amount of
MSW left without collection can be estimated (TERI, 2003).
At present, the three composting plants are operating at about
50% of its design capacity i.e. 850 t/day because of high
operating and maintenance costs compared with open
landfills, higher compost cost as compared to the commercial
fertilizers and improper separation of the inert materials such
as plastic and glass, which degrade the quality of final
compost. The remaining waste is dumped in three active
landfills. It is assumed that 25 % of waste treated through
composting is converted to compost, 10% is left as residue,
which contribute to the MSW going for landfills and the rest
lost due to respiration and evaporation (MCD, 2004). The
three existing landfills are receiving collected MSW and the
remaining residues of the other processes like recycling and
composting plants. The funds required for MSWM depend on
the funds required for MSW storage, collection and
transportation and the annual operating and maintenance costs
for landfills and composting plants. It is assumed that MSW
storage; collection and transportation consume 90% of the
total funds available for MSWM (MCD, 2004; MCD, 2005;
MCD, 2006; NDMC, 2005; NDMC, 2006). The funds
available for MSWM depend on the economic growth
(GSDP), which in turn influence municipal budget. The per
capita expenditure for MSWM depends on population and the
funds available for MSWM.
To develop a quantitative model the causal loop diagram is
converted to stock flow diagram, which explains the physical
as well as the information flows among various elements of
the MSWM model. The detailed stock flow diagram of
MSWM model is explained in Fig. 2. The MSWMS is
depicting the interaction of MSW generation and population,
per capita GSDP and per capita MSW generation rate. The
system also defines the quantity of MSW collected,
uncollected, recycled, composted and disposed of in landfills.
In addition, the system determines the funds required for
MSWM and the surplus or deficit in MSWM budget. The
MSW generated is considered to be product of the two
variables: the population (P) and the per capita MSW
generation rate (MSWpc). The per capita generation rate
increase with the increases in per capita GSDP (GSDPpc),

which in turn influenced by the economic growth (GSDP),
urbanization rate and the living standards of the residents in
the city. The annual MSW generation is computed using the
following dynamo equations:
MSWg = P * MSWpc
Where, P = Pinitial * (1 + annual net growth rate) n
; n: year
MSWpc = f (GSDPpc , time)
The MSW collected (MSWc) depends on the collection
efficiency (Ceff) and the quantity of MSW recycled (MSWr),
which calculated from the recyclables fraction (Rfr) and
recycling efficiency (Reff) and affected by the annual growth
rate of Rfr. The following equations can be used to determine
MSWc, MSWr and MSW uncollected (MSWunc)
MSWc = Ceff * (MSWg – MSWr)
MSWr = Rfr * Reff * MSWg
MSWunc = MSWg – (MSWc + MSWr)
The amount of MSW composted (MSWcomp) depends on the
operation efficiency for the composting plants. The initial
design capacity of composting plants is 850 t/day in 2001, and
it is assumed that this amount reduces yearly and reach 500
t/day in 2006. It is assumed that 25 % of waste treated through
composting is converted to compost. The amount of MSW,
which disposed of at landfills (MSWdis) depends on MSWc
and MSWcomp
MSWdis = MSWc - MSWcomp
3.3. A System Dynamics Model for the Proposed
MSWMS (2006-2024)
Proposed scenario is categorized as policy scenario under
which proposed mixture of MSW treatment technologies has
been analyzed. For the treatment technologies it is assumed
that the capacity enhancement and waste diversion to available
treatment methods will be according to the proposed policy of
MCD. Following the MSW Rules 2000 (MoEF, 2000), MCD
has proposed a scheme for treatment and disposal of MSW in
the entire State of Delhi for 2004-2024. The proposed policy
aims at both the reduction of final waste to be disposed of as
well as reducing the environmental effects of waste treatment.
The specific targets, developed with respect to MSW
treatment and disposal, are as follows:
The proposed technologies for MSW treatment are
composting, biomethanation and refuse derived fuel
(RDF). The different MSW treatment technologies
capacity will be increased stepwise in future.
The current open landfilling practices will be
replaced with sanitary landfilling by the year 2011.
The sanitary landfills and the existing landfills will
be provided with the facility of landfill gas recovery
system after closure.
The detailed stock flow diagram of the proposed MSWMS
model is explained in Fig 3. The MSWMS is depicting the
interaction of MSW generation and population, and per capita
MSW generation rate. The system also defines the quantity of
MSW collected, uncollected, recycled, composted, treated by
biomethanation and RDF plants and disposed of in landfills. In
addition, the system determines the estimated budget for
MSWM for the period 2001-2024. The MSW generated is
considered to be product of the two variables: the population
(P) and the per capita MSW generation rate (MSWpc). The
annual MSW generation is computed using the following
dynamo equations:
MSWg = P * MSWpc
Where, P = Pinitial * (1 + annual net growth rate) n
; n: year
The MSW collected (MSWc) depends on the collection
efficiency (Ceff) and the quantity of MSW recycled (MSWr).
The collection efficiency (Ceff) was taken as 80% during 2001-
2005 and it is assumed to reach 90% then 100% in 2006 and
2011 respectively, and this means that all MSW generated in
2011 should be collected. The quantity of MSW recycled
(MSWr) was calculated from the recyclables fraction (Rfr) and
recycling efficiency (Reff) and it is affected by the annual
growth rate of Rfr. The following equations can be used to
determine MSWc, MSWr and MSW uncollected (MSWunc)
MSWc = Ceff * (MSWg – MSWr)
MSWr = Rfr * Reff * MSWg
MSWunc = MSWg – (MSWc + MSWr)
The amounts of MSW composted (MSWcomp), treated by
biomethanation (MSWbiom) and treated by RDF plants
(MSWrdf) are presented in Table and Table. The amount of
MSW, which disposed of at landfills (MSWdis) depends on
MSWc, MSW treated
MSWdis = MSWc – (MSWcomp + MSWbiom + MSWrdf)
In order to estimate the budget required for proposed MSW
disposal and treatment facilities during 2001-2024, it is
necessary to estimate the costs required and the revenues
resulted from these facilities. The revenues from different
disposal and treatment facilities were estimated by considering
that the composting market is 1000 Rs./t and the market of
electricity generated from different facilities is 3250 Rs./Mwh.

4. RESULT AND DISCUSSION
4.1. Existing Scenario (2001-2006)
The trend for population and various major variables as MSW
generated, collected, uncollected, recycled, disposed of and
composted (treated) for the existing scenario is shown in Fig.
4 and Fig. 5. The population of Delhi increased from 13.85
million in 2001 to 15.98 million in 2006 with annual net
growth rate 2.9% and the MSW generated increased from 2.27
million ton in 2001 to 2.73 million ton in 2006 with annual
rate 3.75%. The rate MSW disposed of in landfill was
increased from 62% in 2001 to 68 % in 2006 of the MSW
generation and the rate of recyclables increased from 7.5% in
2001 to 7.7% in 2006, while the rate of MSW composted
decreased from 13.7% in 2001 to 6.7% in 2006. The compost
production rate decreased from 77 thousands ton in 2001 to 45
thousands ton in 2006 as shown in Fig. 6. In addition the
deficit in MSWM budget decreased from Rs. 94 million in
2001 to Rs. 35 million in 2006 and the per capita expenditure
on MSWM decreased from 7 Rs./year in 2001 to 2 Rs./year in
2006 as shown in Fig. 7 and Fig. 8.
4.2. Proposed Scenario (2006-2024)
The trend for population and various major variables as MSW
generated, collected, uncollected, recycled, disposed of and
treated for the proposed scenario is shown in Fig. 9, Fig. 10
and Fig 11. The population of Delhi increased from 13.85
million in 2001 to 26.73 million in 2024 and the MSW
generated increased from 2.27 million ton (6232 t/day) in
2001 to 5.95 million ton (16300 t/day) in 2024 with annual
rate 4.28%. The rate of MSW collected increased from 75%
in 2001 to 84 in 2006 and then to 90% in 2024. The rate MSW
disposed of in landfill was increased from 62.5% in 2001 to
77% in 2006 and then decreased to 56.6 % in 2024 of the
MSW generation, while the rate of recyclables increased from
6.5% in 2001 to 7.2% in 2006 and 10.3% in 2024 and the rate
of MSW treated decreased from 13.7% in 2001 to 6.5% and
then increased to 36.8% in 2024. The per capita generation
rate increased from 0.45 kg/day in 2001 to 0.48 kg/day in
2006 and 0.61 kg/day in 2024 as shown in Fig. 12. The
compost production rate decreased from 77 thousands ton in
2001 to 45 thousands ton in 2006 and then increased to 342
thousands in 2026 as shown in Fig. 13.
The electrical energy capacity generated from MSW disposal
and treatment facilities is shown in Fig. 14 and Table 8. The
electrical energy generation potential increased from 0 in 2001
to 58379.5 Mwh in 2007 and 302275.3 Mwh in 2024. This
energy can be used in operating the treatment plants and the
extra can be sold to supply a significant portion of the city
creating revenue can be added to the municipalities budgets.
The estimated costs and revenues of different MSW disposal
and treatment facilities are shown in Fig. 15, 16 and 17. As
shown in Table 9, the projection revenue produced from
different facilities increased from 0 in 2001 to 334.42 (million
Rs.) in 2007 and 2068.6 (million Rs.) in 2024 and this revenue
affect positively the budget required for MSW disposal and
treatment facilities by covering the costs required for these
facilities in 2024, where the budget required is negative
because the revenue is more than the costs.
CONCLUSIONS
A system dynamics model has been developed to analyze the
existing (2001-2006) and proposed scenario (2006-2024) of
MSWMS in Delhi. The result of this model showed that the
generation of MSW in Delhi would increase during 2006-2024
with the increased population at annual rate 4.28%. There is
increase in the rate of MSW collected and recycled, while
MSW disposed of in landfill will decrease up to 56.6 % in
2024 of the MSW generation with increasing the rate of MSW
treated. The per capita generation rate will be 0.61 kg/day in
2024 and the compost production rate will be 342 thousands in
2024. The electrical energy generation potential from various
MSW treatment methods will increase from 0 in 2001 to
58379.5 Mwh in 2007 and 302275.3 Mwh in 2024. The
projection revenue produced from different facilities will
increase from 0 in 2001 to 334.42 (million Rs.) in 2007 and
2068.6 (million Rs.) in 2024 and this revenue affect positively
the budget required for MSW disposal and treatment facilities
by covering the costs required for these facilities in 2024,
where the budget required is negative because the revenue is
more than the costs.
