Short Notes for Class 6 Science Chapter 16 Garbage in, Garbage out

Landfill is an area where the garbage collected from a city or town is dumped. The area is later converted into a park. Converting plant and animal waste including that from kitchen, into manure, is called composting. The method of making compost from kitchen garbage using redworms is called vermicomposting. Paper can be recycled to get useful products. Plastics cannot be converted into less harmful substances by the process of composting. We need to generate less waste and find ways of dealing with the increasing amount of garbage in our surroundings.

Non-biodegradable waste like plastic, polybags also add also harmful factors to environment. We must ensure ways to reduce generation of garbage. Wherever possible, we must use recyclable material in our daily use.

  • Plastic Bags - Toys covers, sarees bags, shopping bags, etc.
  • Wooden Boxes - Fruit baskets and boxes for hardware.
  • Jute Bags - School bags, shopping bags, vegetable bags, etc.

(b) By reusing the packaging material, we can reduced packaging material.

(c) The basic purpose of packaging is to protect the product from tampering and to maintain its freshness. However, most of the packaging material is used to beautify the boxes and make them look attractive on the shelves. Unfortunately a large volume of packaging material goes waste and is thrown into dustbin. For example, in most of the places, the dustbins are full of chips and biscuits wrappers. It unnecessarily increases the amount of garbage. It also increase the cost of the product due to unnecessary packaging. We should seriously consider how to reduce unnecessary packaging.
