Removing such waste from the rest of the waste stream substantially reduces waste volumes for disposal and also allows biodegradable waste to be composted. Biodegradable waste can be used for composting or a resource for heat, electricity and fuel by means of incineration or anaerobic digestion. [7] Swiss Kompogas and the Danish AIKAN process ...
Per capita waste generation in OECD countries has increased by 14% since 1990, and 35% since 1980. [3] Waste generation generally grows at a rate slightly lower than GDP in these countries. Developed countries consume more than 60% of the world industrial raw materials and only comprise 22% of the world's population. [4]
Waste comes in many different forms and may be categorized in a variety of ways. The types listed here are not necessarily exclusive and there may be considerable overlap so that one waste entity may fall into one to many types.
However, if these waste streams are commonly and frequently confused, then the disposal process is not at all optimized. [44] Biodegradable and compostable materials have been developed to ensure more of human waste is able to breakdown and return to its previous state, or in the case of composting even add nutrients to the ground.

Green waste can be collected via municipal curbside collection schemes or through private waste management businesses. Many communities, especially in the United Kingdom, have initiated green waste recycling and collection programs in order to decrease the amount of biodegradable materials in landfills. [1]

A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero.
