Which of the following methods is NOT applied for disposal of nonbiodegradable substances?
Making Compost
Non-biodegradable substances such as plastics, glass, metals and many synthetic materials cannot be broken down by bacteria and other decomposers into simpler harmless substances.
Composting works only on biodegradable waste, such as kitchen scraps and leaves, which microorganisms decompose into manure. Since non-biodegradable substances are not decomposed, compost cannot be made from them, so this method is not applied for their disposal.
Recycling turns such materials (for example plastic, paper and metal) into new products, reusing puts the same article to use again, and landfilling buries waste in specially prepared low-lying sites. All three are used for handling non-biodegradable waste.
Hence, Making Compost.
