Highlights the transfer and transport of solid wastes as one of the integrated components of SWM. It discusses the types of transfer stations, enumerates the means and methods involve in wastes transport and concludes on the present scenario of SWM in India.
Solid waste means any garbage, refuse, sludge from a wastewater treatment plant, water supply treatment plant, or air pollution control facility and other discarded materials including solid, liquid, semi-solid, or contained gaseous material, resulting from industrial, commercial, mining and agricultural operations, and from community activities.
The characteristics, quantities, volume and composition of solid waste generated may differ from one country to another and between urban and rural areas.
It depends mainly upon the customs, climate, living conditions and economic standard of the area. As a consequence, if solid waste management is to be accomplished in an efficient and orderly manner, the fundamental aspects and relationships involved must be identified, adjusted for uniformity of data, and understood clearly. This section deals about :Solid Waste Generation ; Solid Waste Handling, Storage and Processing at the Source.

Municipal Government &
Transfer Station
Problem: A municipal government has agreed to provide once per week waste collection services to a
new residential community of 25,000 people. The city council has hired you to make a preliminary
assessment to determine if they should build and operate a transfer station to support the collection.
For the initial analysis, assume that the community does not have a recycling program. Here is some
of the initial data that the municipal engineer has collected.
* The round trip distance from the residential community to the landfill is 40 miles.
* The size of the residential garbage truck that collects waste from the community is 30 cubic yards.
* The round trip distance from the proposed site of the transfer station will be 45 miles.
* The garbage truck is capable to compact the refuse to 700 lbs./yd3.
* A long haul truck is capable to transport 25 tons of compacted waste per trip.
* The transfer station has a fixed operating cost of $15/ton.
* The cost to operate the garbage truck is $1.50/mile.
* The cost to operate the long haul truck is $0.75/mile.
(a) Would you recommend to the city council that a transfer station should be built and operated?
Show all work on how you came to your answer.
* The United Nations estimates waste generation rate is 4.8 lbs. per person per day.
(See page 39 of the textbook)
(b) If the community operated a recycling program, would this change or support your
recommendation to the city council? Show all work on how you came to your answer.
* Total recycled municipal waste is 33.2% of generation.
Solution
:
(a) We will use the estimated waste generation rate of 4.8 lbs. per person per day in this calculation.
Step 1
Residential waste generated = 25,000 people x 4.8 lbs. x 7 days = 840,000 lbs. or 420 tons
person/day 1 week each week
Step 2
Calculate the waste collected in each truck:
30 yd3 x 700 lbs. = 21,000 lbs. of waste collected per truck
truck yd3
Step 3
Calculate the number of trucks needed:
840,000 lbs. = 40 trucks (round up)
21,000 lbs./truck
Step 4
Determine the cost to travel to landfill by garbage trucks:
40 trucks x $1.50 x 40 miles = $2,400 per week
week mile

Step 5
Calculate the number of long haul trucks based on residential waste generated:
420 tons = 17 trucks (round up)
25 tons per truck
Step 6
Determine cost to travel to transfer station by long haul trucks:
17 trucks x $0.75 x 45 miles = $573.75
mile .

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Presentation Title: Transportation of Solid Wastes
Anthony Nimely Chea, Jr.
2k19/ENE/17
2. Objectives
To create an understanding of the Solid Wastes(SW) stored at wastes storage deports at regular
interval so as to
ensure that no garbage bins/containers overflow
ensure that no waste is seen littered on streets
To safeguard the
efficiency of the transport system
cost effectiveness of the system
maintainability of the system
synchronization of the storage deports
3. Transfer and Transport
This is the 5th functional element of Solid Wastes Management System
Even though Transfer and Transport is not a part of the hierarchical order of an Integrated Solid
Wastes Management System, they are carried out from the 1st rank to the 4th rank of Solid Wastes
Management.
It indicates that transportation of SW cannot be done without transferring the waste. Therefore,
this functional element takes place in two steps:
The transfer of the wastes from the smaller collection vehicle to the larger transport equipment
and
the subsequent transport of the wastes, usually over long distances, to a processing or disposal
site.
5. Types of Transfer Stations
A) Direct-load
B) Storage-load
C)Combined-
direct load and
discharged load
6. Transport Means & Methods
Wastes can be transported to
processing/recovery facility or disposal
sites by motor vehicles, railroads, and
ocean-going vessels.
Pneumatic and hydraulic systems have
also been used to transport wastes.
Typical transport vehicles used
7. Transport Means & Methods Cont’d
Railroads
Rails were commonly used for the transport
of SW in the past, they are now used only by
few communities.
Renewed interest is now developing in the
used of railroads, especially in transporting
wastes to remote landfills
Usually done over a distance of 300 miles
Vessels
25 to 28 tons of waste are compacted in
40ft container and placed on shipping
One of the major problems encountered is
that it is often impossible to move the barges
and boats during time of heavy seas
This is no longer in used in some parts of
the world
8. Transport Means & Methods Cont’d
Pneumatic & Hydraulic System
Both low-pressure air and vacuum conduit
transport systems have been used to
transport solid wastes
The most common is the transport of wastes
from high density apartments or commercial
activities to central location for processing
or for loading into transport vehicle
9. Present Indian Scenario
Inefficient and Unscientific Manual Loading
of Waste
Manual Handling of Wastes
No synchronization between b/w waste
storage depots & Transportation
Wastes are loaded in bags
Consumes time
Reduces productivity
Unhealthy
Loading through Front-End Loader
Advantage
Cost effective
Disadvantage
Improper cleaning of wastes depots
Damages floor and screen walls, leads to nuisance if
repairs are not carried out
In cities where Dhalavs or large masonry bins are
used, waste is not regularly removed from inside of
such structures
10. Irregular Transportation/ Under Utilization
Cities and towns have limited fleet of vehicles,
most of which are old
Wastes are seen lying in heap
Wastes are seen lying at unscientifically
designed dust bins which causes nuisance
and unhygienic conditions
A 5-6 tonnes solid wastes vehicle will
transport 1-3 tonnes, making transportation
inefficient and uneconomical
11. Present Indian Scenario Cont’d
Bio-Medical Waste From Hospitals, Nursing
Homes, Health Care Establishments Etc.
Has to be arranged by waste producers or their
associations and wastes aren’t collect
The instructions contained in the Biomedical
Waste (Management and Handling) Rules 1998
may be followed
Waste From Hotels & Restaurants
Hotels and restaurants waste should be collected
once or twice daily through a contract given by the
associations of hotels and restaurants, or at their
request by local bodies on cost recovery basis
The entire collection and transport system could
be privatized and rates may be prescribed by the
associations or local bodies.
12. Present Indian Scenario Cont’d
Workshop facility for vehicles maintenance
All local bodies must have adequate workshop facilities for the maintenance of their fleet of
vehicles and containers, handcarts etc.
The workshop, public or private, should have adequate technical staff, spares and preventive
maintenance schedules to ensure that at least 80% of the vehicles remain on the road each
day and the down time of repair/maintenance is minimized to the extent possible.
13. Present Indian Scenario Cont’d
MEASURES TO BE TAKEN TO IMPROVE THE
SYSTEM
i. System of transportation should be such
that it can be easily maintained
departmentally or through private garages
ii. Manual loading should be discouraged and
phased out expeditiously and replaced by
direct lifting of containers through hydraulic
system or non-hydraulic devices or direct
loading of waste into transport vehicles
iii. Transportation of waste should be done
regularly to ensure that the containers
/trolleys and dustbin sites are cleared
before they start overflowing.
iv. The system of transportation of waste
must synchronize with bulk storage of
waste at the temporary waste storage
depots.
14. Health and Environmental Impacts of Transfer
Stations
Transfer station staff, who will be exposed to
all the waste hazards (including physical
damage from sharp items, human faecal and
other pathogens, heavy metals and dust and
other chemicals), should be provided with,
and required to use, protective
equipment(boots, gloves, hard hats, dust
masks, high visibility jackets and safety
glasses).
16. Conclusion
Small cities having a few vehicles can have parking in the workshop itself; but in big cities where large
distances are to be travelled.
It is desirable to have parking depots in different parts of the city to reduce dead mileage of vehicles.
Cities above 5 lacs population should think of having more than one depot for parking of vehicles in
different directions of the city.
Cities above 2 million should think of having at least 3 to 4 such depots to reduce the congestion in the
workshop and also to cater the needs of the different sectors of the city from the depot close by. This
will save lot of dead mileage and add to the efficiency of transport system.
