Organic materials, such as yard trimmings, food scraps, wood waste, and paper and paperboard products, typically make up about one-third (by weight) of the municipal solid waste stream. [1] SSO programs depend on the composition of local waste stream, acceptance specifications for the organics processing facility, and collection methods.
Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane, compost, humus, and simple organic molecules by micro-organisms and other living things by composting, aerobic digestion, anaerobic digestion or similar processes.
green waste (green organic material or green organics, sometimes referred to as "green wealth") - plant material discarded as non-putrescible waste - includes tree and shrub cuttings and prunings, grass clippings, leaves, natural (untreated) timber waste and weeds (noxious or otherwise).
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.
Non-aqueous phase liquids, or NAPLs, are organic liquid contaminants characterized by their relative immiscibility with water. Common examples of NAPLs are petroleum products, coal tars, chlorinated solvents, and pesticides. Strategies employed for their removal from the subsurface environment have expanded since the late-20th century. [1] [2]
In 2000, the United States Supreme Court ruled on Solid Waste Agency of Northern Cook County v. US Army Corps of Engineers. This ruling struck down the Corps' ability to prevent the construction of a disposal site for non-hazardous waste in Illinois based on power derived from the commerce clause. [51]
The condensed liquid organic is removed from the site. Depending on its composition, the liquid is either recycled as a supplemental fuel or destroyed in a fixed base incinerator. A thermal desorber removing 500 mg/kg of organic contaminants from 20,000 tons of soil will produce less than 3,000 US gallons (11,000 L) of liquid organic.
Waste management laws govern the transport, treatment, storage, and disposal of all manner of waste, including municipal solid waste, hazardous waste, and nuclear waste, among many other types. Waste laws are generally designed to minimize or eliminate the uncontrolled dispersal of waste materials into the environment in a manner that may cause ...
