Answer 2

The biodegradable domestic garbage such as fruit and vegetable peels, left-over food and fallen leaves can be disposed of by converting it into compost which is used as a manure (or fertiliser) for growing plants. Compost contains nutrients required for the growth of plants.he composting process requires organic waste, such as leaves, grass, fruit and vegetable scraps, soil (which contains microorganisms), water and oxygen. The microorganisms eat the organic waste, breaking it down into its simplest components.Materials to Avoid. Coal Ash – Most ashes are safe to mix into your compost pile, but coal ashes are not. ... Meat, Bones, Fish, Fats, Dairy – These products can “overheat” your compost pile (not to mention make it stinky and attract animals).
