Biodegradable waste is a type of compost that has elements which breakdown more easily. Bioplastics are plastics that come from plants sources like hemp and soy beans as well as corn starch, as opposed to traditional plastics which are derived from petroleum. Biodegradable waste is cheap and good for our environment. These types of plastics degrade when they're exposed to oxygen or light however it is not a microbial degradation and this does not happen in a commercial compost bin or unit.
