Full Answer

Biodegradable wastes are quickly broken down by microorganisms in normal environmental conditions. This category is mainly food scraps. It is further split into animal-derived and plant-derived waste. Animal waste must be handled separately from plant waste, especially if the food waste is intended for animal feed. In addition, the organisms that help break down biodegradable waste are different for animals and plants, with animal-derived waste posing a greater health risk.

Non-biodegradable waste is the source of much of humanity's waste disposal problem. Paper, metals, glass, plastic and textiles are all classified as non-biodegradable, due to the long or indefinite time it takes for them to break down naturally. Many of these wastes, but not all, can be recycled. Others, such as plastic, are inefficient to recycle, and much of the plastic waste placed in recycling bins winds up in a landfill anyway.
