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.
Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.
In 1988, San Francisco's Solid Waste Management Program set diversion goals, calling for a 32 percent reduction in the city's waste stream by 1992 and 43 percent by 2002. However, in 1989, the California legislature preempted San Francisco's goals by passing the Integrated Waste Management Act (AB 939), which set waste reduction goals of 25 ...
A big part of waste management deals with municipal solid waste, which is created by industrial, commercial, and household activity. [4] Waste management practices are not the same across countries (developed and developing nations); regions (urban and rural areas), and residential and industrial sectors can all take different approaches.

Most waste management laws are designed to reduce the generation of waste and promote or mandate waste recycling. Waste management laws also regulate organic waste disposal, including composting which is increasingly being recognized as a more sustainable alternative to landfilling and incineration. Regulatory efforts include classifying waste ...
Resource recovery can be enabled by changes in government policy and regulation, circular economy infrastructure such as improved 'binfrastructure' to promote source separation and waste collection, reuse and recycling, [5] innovative circular business models, [6] and valuing materials and products in terms of their economic but also their social and environmental costs and benefits.

The two broad categories of organic solid waste are green and brown. Green waste is generally considered a source of nitrogen and includes pre- and post-consumer food waste, grass clippings, garden trimmings, and fresh leaves. [1] Animal carcasses, roadkill, and butcher residue can also be composted, and these are considered nitrogen sources. [33]
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.
