 5.1.1 Introduction

 Those items come under the category of garbage, which we do not need (personally, in office, school, industry, hospital) and are thrown away.  There are some things which we keep with us, but according to the rule, we should throw them because they are harmful to ourselves and the society.  The items that fall into the category of waste are of different types, ranging from a small old brush to as big as the body of a school bus.

 Generally every person spreads some or the other garbage but some people are very cautious about the environment and they spread very little garbage.  Equally, some people don’t waste and preserve things, while others are very frightening and they cause huge environmental problems for the people and animals living on the earth.

 5.1.4 Safe Disposal of Waste

 Every household that has garbage has a duty to dispose of it safely.  But before throwing the waste, it is very necessary to divide it according to the table given above.  For this task, you must have separate dustbins in the house.  Given below are some ways in which waste can be disposed of at home.  ,

 After laying the newspaper in the wet waste bin, the wet waste should be collected in it.  You should lay the paper in the dustbin in such a way that it covers the sides of the dustbin properly.  Now you can collect the wet waste in it.  Keep in mind that plastic bags should never be used to collect wet waste.

 You can also make compost from wet waste, which can then be used as fertilizer and soil conditioner.  This work can also be done in earthen pots.  The dustbin generally used for wet waste is green in colour.

  • Dry waste – To collect dry waste, you should put a plastic garbage bag in the dustbin. Collect all the garbage in the dustbin and throw it in the garbage dump. Keep in mind that items like milk bags, yogurt cups, juice tray packs should be cleaned thoroughly before throwing them in the dustbin.  If you forget to give the garbage to the garbage collector, since this garbage is dry, it can stay in the house for a day or two.  The color of the dustbin used for dry waste is blue.
  • Sanitary waste – Sanitary waste should not be mixed with wet and dry waste. It should be disposed of separately.  Sanitary waste bins should be placed in the bathroom and a garbage bag should be placed in the dustbin.  Sanitary pads and diapers should be wrapped in paper before they are thrown in the trash.  The diaper must be washed in the toilet before it is thrown in the trash.  This dustbin should be cleaned daily as it can harbor germs and make the bathroom smelly.  Before handing over the sanitary waste to the garbage collector, the dustbin bag should be tightly tied.
  • Harmful waste This waste can be harmful to the health of individuals and the environment – it should be disposed of with care as it may be flammable, reactive, corrosive or toxic. For example, broken glass can be harmful, so it should be properly wrapped in a separate garbage bag before giving it to the garbage collector.  Similarly, insecticides and other spray bottles should be given to him separately.  The color of the dustbin is red for the harmful waste.  In some countries, special counters are set up to dispose of harmful waste or a separate vehicle is provided to collect it.
