Two methods by which we can reduce the problem of waste disposal are- a.) Reduce, Reuse and a.) Recycle - The style of living had a drastic effect on the amount of waste generated, which allows the use of unnecessary products. So, we must try prevent us from buying unnecessary products and reduce the amount of waste generated. If the waste generated can be used again for some purpose, reuse it. If it can't be reused again recycle it.
b.) Incineration - Incineration is the process where combustion of waste takes place in containers known as incinerators. The byproducts so formed are ash, some gases and a lot of heat. The heat energy can be stored and put to use in homes in cooking and heating etc. The ash can be used as an ingredient in agriculture, whereas the gases can be be reduced to their non - poisonous forms and finally released. This is one of the most sustainable waste disposal method.
