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.
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.
