WASTE: When something is unwanted, useless or no longer serves a purpose, it is termed as waste. It may be solid, liquid or gaseous depending upon the states of matter. There are various kinds of waste:
- Wet waste.
- Dry waste.
- Hazardous waste.
- Biomedical waste.
- Construction waste.
WHEN WASTE IS A PROBLEM: Waste is a problem when quantity and concentration are too much and it becomes a hazard. If waste is not properly managed and disposed of it can become harmful to health and also it can damage the environment.
DEALING WITH GARBAGE: The waste or garbage is collected by safai karmcharis in trucks and is taken to a low-lying open area called a landfill. There are two parts of garbage one which can be used again and one that cannot be used. The non-useful component of garbage is separated out. It is then spread over the landfill and then covered with a layer of soil. Once the landfill is completely full, it is then converted into a park or a playground.
VERMICOMPOSTING: The method of preparing compost from kitchen waste with help of red worms is termed vermicomposting. It is a very high-quality manure. We can use this manure in pots, gardens and agricultural fields.
THINK AND THROW: Every house has a huge amount of garbage to dispose of. The amount of garbage is increasing day by day and it getting difficult to dispose it off. So, we need to think about it seriously. We should use some things again if possible before throwing them as waste.
RECYCLING OF PAPER: Recycling means collecting and separating the used and discarded items made up of paper, plastic, glass and metals and sending them to respective industries to make fresh paper, plastic, glass and metal objects. Recycling of paper means reprocessing of old papers, waste papers, old newspapers, magazines, books and notebooks to make new paper or cardboard.
PLASTICS – BOON OR A CURSE? There is a large variety of things which we use in our daily life are made of plastic. For example, plastic bags, bottles, shoes, combs, toothbrushes, strainers, buckets, mugs etc. Due to the vast use of materials made of plastics, it is difficult for us to imagine our life without plastics. This makes plastic a boon for us. But plastic becomes a curse when we use things made of plastic excessively and do not dispose of their waste properly.
