Hint-Proceed the solution of this question with the knowledge that the materials which can be recycled and reused should be put in the blue dust bin because these materials cannot rot but can be recycled. While materials which are biodegradables are collected in the green dustbin which can be used to prepare compost. Complete Step-by-Step solution: (1) Blue coloured bins are used for collecting materials that are recyclable. The recyclable materials include paper- newspaper, magazines, etc., cardboard, food tins, glass bottles and jars, plastic bottles, tetra pack packaging, etc. (2) The green bins are used for collecting kitchen and other plant or animal wastes. This type of waste rots completely when buried in the soil. It includes wastes like plate scrapings, vegetable peelings, meat and bones, cooked and uncooked food, cut flowers, etc. Note- In this particular question we should know that Garbage substances which are biodegradable can be converted into compost by the red worms, saprophytic such as moulds (white, black or greyish cottony patches) and bacteria (which can be seen under microscope) that help in decomposing biodegradable substances. While non-biodegradable waste is of two Types-Recyclable: waste having economic values but destined for disposal can be recovered and reused along with their energy value and non-recyclable: waste which do not have economic value of recovery.
