We all generate waste and particularly liquid and solid waste. Liquid waste is generally disposed in severing lines and in many countries, this liquid waste is treated in large water treatment plant and after treating, fresh water is released in the rivers, ponds or any other means to earth. Solid waste is of two types, and one is biodegradable and another is non-biodegradable.

The solid waste is collected by a municipality and however, managing waste is a critical task of municipal corporations. There are two components in solid waste; one is organic in nature, and another is recyclable.  India at present lack in waste management and only a part of the urban waste is disposed properly.

 (1)    Biodegradable Waste:  Biodegradable waste is one which automatically converted into the smaller non-toxic and harmless substances by the action of microbes, and they will form the part of the soil in due course of time. However, some of these can be recycled such as paper.

(2)    Non-biodegradable Waste: These are the materials, which cannot be converted down further to smaller non-harmful substances and examples include plastic, broken glass and metals. 

 •    We need to identify clearly the non-biodegradable materials and by recycling them, we can better manage our waste.

•    We should also ensure that dangerous materials to earth as these can cause soil and water pollution and one such substance is mercury, PCBs and there are many other banned substances, which should never be thrown into the pit or earth.
