Organic materials collected in SSO programs typically get delivered to composting facilities where the waste is turned into nutrient-rich soil amendments known as compost. Organic feedstock can also be delivered to anaerobic digestion facilities that produce biogas, a source of renewable energy. The resulting biogas (methane) can then be used ...
Landfill gas utilization and municipal composting can capture and use the organic nutrients. [11] Food waste collected from non-industrial sources is harder to use, because it often has much greater diversity than other sources of waste—different locations and different windows of time produce very different compositions of material, making ...
Environmental Waste Solutions was founded in 1994 by Darwyn Williams. The initial idea for the EWS business model came from Williams' first entrepreneurial pursuit, where his business plan was focused on helping businesses in the Baton Rouge area to save money on their over-assessed property taxes at no cost other than a portion of their savings.

Primary treatment is the "removal of a portion of the suspended solids and organic matter from the sewage". [5]: 11 It consists of allowing sewage to pass slowly through a basin where heavy solids can settle to the bottom while oil, grease and lighter solids float to the surface and are skimmed off.
High-level waste will be processed and vitrified later in a separate process. [3] The Hanford Site is currently storing 56 million gallons of radioactive waste in aging underground tanks, legacy waste from plutonium production efforts during World War II and the Cold War. The majority of the waste in the tanks is low-activity waste liquids. [4]
Liquid waste is an important category of waste management because it is so difficult to deal with. Unlike solid wastes, liquid wastes cannot be easily picked up and removed from an environment. Liquid wastes spread out, and easily pollute other sources of liquid if brought into contact.
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.
A centralized waste treatment (CWT) facility processes liquid or solid industrial wastes generated by off-site manufacturing facilities. A manufacturer may send its wastes to a CWT plant, rather than perform treatment on site, due to constraints such as limited land availability, difficulty in designing and operating an on-site system, or ...
