Recycling wastage to energy

Coming to waste management, it is always a hassle for the authorities to find a complete solution in disposal of the same. Developing countries like India, where wastages are dumped directly into public places and water resources; it is an intricate situation which is not addressed yet. Polluted air and water are the major cause of environmental crisis in India. Lack of sophisticated system to dispose wastages lets the public and government authorities ignore the importance of neat and clean environment. Social responsibility is always treated as a ‘not my job’ thing by them.

Convert waste to energy

However, this article looks more into the recycling of wastage and generating energy through it. Recycling wastage to energy is a part of waste management. In many developed countries, wastages are used as raw material for producing energy, gas etc. This recycling not only benefits the environment but also reduces the production cost and resources. It is economical and reduces pollution due to wastages dumped into open areas and water resources.

There are many methods used for converting wastages to energy. The most conventional method is direct combustion where the heat generated by wastages is converted to energy using steam turbine. In countries where homes needed to be heated, the heart from wastages is circulated using warm hole. Thus they can avoid the use of electrical equipments to get heat. Fuel also can be generated from waste. Methane generated from landfill gas is a fuel produced from wastage. Anaerobic digestion is another method to produce bio-gas from wastages like sewage, food waste etc. The bio-gas thus produced can be used directly for cooking and heating home.

Along with conventional methods of producing energy from wastage, advanced technologies are also being used by many countries. Gasification is an advanced conversion to produce combustible gas which is a combination of carbon monoxide, hydrogen, carbon dioxide and methane. This gas is ready to use directly for generating heat and electricity. Pyrolysis is another method of conversion to produce combustible gas, oil or solid char (sometimes known as biocoal). Technology can be chosen depending on the nature of available wastage.

The recycling of wastage contributes a lot to the environment, society and health related solutions. Instead of depending of natural resources to produce energy, which often distracts the eco-system, a well planned system to produce energy is more economic and eco-friendly. It not only gives clean and safe environment and water to humane, but it also protects other species that equally shares this world with us. Inhabitants of oceans for example, discharging bulk amount of wastage into ocean have put inverse effect on the inhabitants. Wastages turned poison kills millions of creatures under water and sometimes it leads to the extinction of a species from the earth.

Who would like to live in a stinky atmosphere? Whether it is human or animal, we all need fresh air and water to lead a healthy life. Sophisticated methods to dispose wastage will definitely help in creating a world that smells sweat.
