In my opinion, considering the current scenario of Bangladesh , waste can be an important sector or source for electricity generation.
Since the industrial revolution, waste has been a major environmental issue worldwide. Wastes are materials we don’t need and thrown as trash.
Waste can be solid or liquid. Liquide waste can come in non-solid form. Example of liquid waste include wash water, liquid used to clean in industries. On the other hand, solid waste in any garbage and rubbish we make at our home or any places. Examples of solid waste include car tyres, newspapers, broken glass, broken furniture and even food waste.
Due to proper planning of wastage that comes from industry, household, and others sector it becomes a big problem for the Bangladesh. Not only for the environmental damage but also it creates so many problems like it damage or reduce the fertilization capability of soil, river water becomes toxic and it also need a place to store. This type of waste can easily catch fire, explode and be poisonous to human health.
I want to refer a paper title “Bangladesh waste database 2014”
This report covers 271 urban localities in Bangladesh of which 10 cities/city corporations, 106 are Category A pourashavas, 96 are Category B pourashavas, 56 are Category C pourashavas and 3 are defined as a special category.
Total domestic urban waste generation: 11,808.463 tons per day during the dry season.
In order to include the portion of waste generated from non-domestic sources in the estimates, the total domestic urban waste generation amount is multiplied by a factor to produce an estimate for the amount of total urban waste generation: 20,900.98 tons per day during the dry season, or 29,261.37 tons per day during the wet season.
The total daily urban waste generation average is estimated to be 23,687.78 tons per day or 0.56kg per capita per day.
Energy from municipal solid waste:
Municipal solid waste (MSW), often called garbage, is used to produce energy at waste-to-energy plants and at landfills in the United States.
In 2018, 68 U.S power plants generated about 14 billion kilowatthours of electricity from burning 29.5 million tons of combustible MSW. Biomass materials accounted for about 64% of the weight of the combustible MSW and for about 51% of the electricity generated.
Since in Bangladesh there are a huge amount of waste and from the above scenario we can see there are a possibility to get a good amount of electricity from waste.
So, I think according to the perspective of Bangladesh this can be very important sector to generate electricity that is from Waste.
