Green waste
Summary
Green waste, also known as "biological waste", is any organic waste that can be composted. It is most usually composed of refuse from gardens such as grass clippings or leaves, and domestic or industrial kitchen wastes. Green waste does not include things such as dried leaves, pine straw, or hay. Such materials are rich in carbon and considered "brown wastes," while green wastes contain high concentrations of nitrogen. Green waste can be used to increase the efficiency of many composting operations and can be added to soil to sustain local nutrient cycling.
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. Communities are provided with, or can provide their own, compost receptacles that they fill with plant and food remains, which are then emptied on a regular basis. Programs such as this allow communities to be an active part of composting their green waste which allows them to play an active role in decreasing the amount of food being dumped into local and regional landfills.
Green waste can be used to improve the quality and sustainability of industrially manufactured topsoils and the sanitariness and efficiency of sewage disposal.
Green waste is an integral part of many manufactured topsoils, as it provides both nutrients for growing plants and increases the volume of manufactured topsoils. Its woody components do not decompose quickly, so they provide the bulk that is necessary for supplementary topsoils. Mixing industrial wastes such as fly ash or coal dust with green waste to create artificial topsoil not only facilitates the repurposing of industrial debris and keeps it out of landfills, but it also allows the nutrients in green waste materials to be cycled back into the environment.
