Study on the Electricity Generation from Municipal Solid Waste of Dhaka cityIJERD Editor
With a population of 170 million Bangladesh is considered as the new growing economic force in
the queue of world trade whereas organic solid waste has been increasing on same scale as the population poses
promising use for it as renewable energy resource. This increasing waste is becoming an issue not only for the
lack of space but also due to it being the cause of illness, pollution, destruction of natural beauty of the city. This
research aims to evaluate and estimates the biogas productions from the municipal solid waste (MSW) through
anaerobic digestion processes. Both Biogas production and power generation from MSW can lead the economy
to prosperity. The estimated potentiality to generate electricity from biogas is 207, 873 and 2878 MW/day, in
years 2020, 2025 and 2050 respectively, could help to meet the increasing demand of electricity in urban

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

The types of wastes or garbage generate are : household ,commercial, industrial
and street sweepings. The mixed municipal solid waste (MSW) comprises food
waste , kitchen waste, green waste, paper waste, plastic waste, glasses, can,
metal, plastic, dirt, rock, clothing, tetra pack, debris, lighting bulb, sand and
wood/board and other miscellaneous items. 50% of the waste is organic including
food and agriculture waste.
2. Population of Town in 2020 :912,795
Per Capita Waste Generation : 0.5-1.0kg/capita/Day (Middle Income Area)
Q1. Calculate the total amount of waste generated by the respective town per day, per week, per
month.
Waste generation: 0.5_1.0 kg per capita per day
Average: 0.75 kg per capita per day
Population: 912,795(2020)
Total Waste generated:
912,795 X 0.75 = 684,596.25 kg/day =684.59625 ton/day
684,596.25 X 7 = 4792173.75 kg/week =4792.17375 ton/day
684,596.25 X 30 = 20537887.5 kg/month =20537.8875 ton/day
Q2. Calculate the percentage of following material using the data below in the total solid waste
generation of respective town (per day, per week, per month)

3. Q3. Calculate the following cost (per day, per week, per month) using the
following data. Assuming that two landfill are available; Jam Chakro and
Govind pass
i. Calculate approximate distance from town to the respective
landfill site considering these sites are 30-35 Km from city centre.
Distance from korangi town to jam chakro = 27km
Distance covered for each cycle = 27km + 27km = 54km
ii. Calculate per ton cost of transportation
(a) Primary transportation
(b) Secondary transportation
4. (a) Primary transportation
Primary transportation will be done manually by labors
Number of labors required for korangi town = 500labors
Salary of each labors = 15000
Cost of labors = 500 X 15000= 7500000 pkr/month
Cost of bags and trolleys = 20000 pkt/month
Totsl cost of primary transportation(per
month)=7520000pkr/month
(b)Secondary transportation
Secondary transportation includes the following
1. Truck
2. Driver
3. Motor coolies
4. Fuel
1. Truck :
Each truck can transfer 5 tons per day
342.295 ton/day waste transferred by =342.295/5 = 68 trucks
Each truck will transfer unattended waste twice a day i.e. two
cycle per day by each truck = 68/2 = 34 trucks
Number of trucks required= 34 trucks per day
Truck rent and parking for 84 trucks =2100000
5. 2. Driver:
Driver required for each truck = 1
Driver required for 84 trucks = 84
Salary of each driver = 25000 pkr/month
Salaries of 84 drivers = 25000 X 84= 2100000 pkr/month
3. Motor coolies:
Motor coolies required for each truck = 2
Motor coolies required for 84 trucks = 84 X 2 = 168
Salary of each motor coolis = 15000
Salaries of 168 motor coolies = 2520000 pkr/month
4. Fuel:
Each truck has to cover 54 km per day for 1 trip
Fuel required for 5 km = 1L
Fuel required for 54 km ( 1cycle) =10.8L ~11L
Fuel required for 108 km ( 2cycle) = 22L
Cost of fuel per L – Rs. 110
Total diesel cost per day :
L of fuel required X No. of trucks X fuel cost per L
= 22L X 34 trucks X Rs.110
6. = 82280 pkr/ day
= 2468400 pkr / month
Total cost of secondary Transportation (per month)
-Truck rent + Drivers salaries + motor coolies salaries + fuel
cost
-2100000 + 2100000 + 2520000 +2468400
-9188400 Pkr/month
Total transportation cost= primary + secondary
= 7520000 + 9188400
= 16708400 Pkr/month
iii. Calculate load transfer per day
Out of total waste generated 684.59625 ton/day.
only 50% has to be land filled ( 30% food waste and
20% agriculture waste)
Load transfer per day = 50% of the total waste
generated is 342.295 ton/day has to be transferred.
