Managing solid waste is a burning issue these days. Management of solid waste is very much essential because if not managed properly, it would have a great harmful impact on the environment. Municipal solid waste probably referred to as garbage includes unwanted trash or useless substances. The main role of municipalities lies with managing these wastes in an efficient manner. It basically includes waste from residential, industrial, and commercial sources.
There are many types of municipal solid wastes, such as:
- Biodegradable waste: Paper, kitchen and food wastes.
- Electronic waste: Electrical appliances such as bulbs, televisions, computers, mobile phones, etc.
- Hazardous waste: Paints, chemicals, pesticides, fertilizers.
- Composite waste: Tetra packs, plastics, etc.
- Recyclable waste: glass, bottles, fabrics, batteries.
Solid wastes could be managed mainly through the process of incineration. Incineration refers to the burning of waste in a specific combustion chamber under controlled conditions, and is, however, offering a medium of managing municipal solid waste, which further helps in recovering the energy stored in materials being burned.
The municipal solid waste incinerator is used to manage the wastes properly. In the incinerators, mixed waste material goes in one end remaining unsorted and later on is burned altogether. Further, resulted ash left behind is settled in a landfill.
Municipal solid waste through incineration is divided into four parts mainly: Recycling, Composting, Disposal, and Waste-to-energy. The hierarchy is based on ‘most preferred’ to ‘least preferred’ taking into account the environmental soundness, reduction, and reuse, composting, recovering energy, treatment and dispose of.
Waste collected is stored in storage containers, which are further transported for segregation and processing. Also, the heat generated from burning materials is used for generating electricity. The hot gases, which rise from burning material heats the water clutched in special tubes around the combustion chamber. After processing, the ash is filled in landfills without creating any nuisance to the environment.
After the dumping cells of managing waste are filled, they are sealed with thick plastic sheets and are covered under diverse feet of dirt. Municipal waste incinerators are used by highly skilled professionals and are carefully maintained. Incineration proves to be a good option as it is not so complex and less expensive.
Incinerators have great features such as combusting efficiency up to 99%, setting the temperature of 750°C to 850°C and 1000°C to 1100°C respectively in primary and secondary chambers. The pollutants generated by incinerators are managed by proper usage of air discharge controlling gadgets, which involve fabric filters, dry scrubbers, and electrostatic precipitators.
Similarly, kitchen waste incinerator is used for disposing of the kitchen waste like tea bags, fruits and vegetable peels, coffee grounds, stale bread, spoiled foodstuffs, etc. It could be easily installed requiring minimal maintenance. They run with the help of oil, electric power or gas. Due to its innovative design, it is smoke-free.
So, it’s not only the duty of government in disposing of the waste. We also as the responsible citizens contribute to managing the waste by throwing the garbage in different bins assigned, thereby helping in segregation and keeping our environment neat and clean.
