Question

Answer question numbers 4(a) - 4(d) on the basis of your understanding
of the following paragraph and the related studied concepts:
India today is facing the problem of overuse of resources,
contamination of water and soil and lack of methods of processing the
waste. The time has come for the world to say goodbye to "single-use
plastics". Steps must be undertaken to develop environment-friendly
substitutes, effective plastic waste collection and methods of its disposal.
Indore treated 15 lakh metric tonnes of waste in just 3 years,
through biomining and bioremediation techniques. Bioremediation
involves introducing microbes into a landfill to naturally break it down
and biomining involves using trommel machines to sift through the waste
to separate the ‘soil' and the waste component. The city managed to chip
away 15 lakh metric tonnes of waste at a cost of around
10 crore. A
similar experiment was successfully carried out in Ahmedabad also.
