Town of Clarkson 511 U.S 383 (1994)): case in which the U.S. Supreme Court overturned a local ordinance that required all solid waste within the Town of Clarkstown be processed at a town-designated privately owned transfer station. The court found that the ordinance unconstitutionally discriminated against interstate commerce.
Comprehensive Environmental Response, Compensation and Liability Act of 1980, 42 U.S. C Section 9601 et seq., referred to colloquially as “Superfund”, providing for clean up and remediation of uncontrolled or abandoned hazardous waste sites and response to accidents, spills and other emergency releases of hazardous substances. CERCLA provides EPA with enforcement authority to ensure that responsible parties pay the cleanup costs. (“PRPs” are Potentially Responsible Parties.)

See Single Stream Recyclables. Contrast Source Separated Recyclables.
Ratio of weight to unit volume of solid waste, recyclables or other materials usually expressed as pounds per cubic yard or kilogram per cubic meter (lbs/y3 or kg/m3). Compaction is achieved in sanitary landfills, collection vehicles and storage containers by using compactors. Greater Compaction Density increases the life of sanitary landfills, route length of collection vehicles or capacity of storage containers. Prescribed Compaction Density may be a performance standard in solid waste management agreements. Compaction Density varies, depending on where and how it is measured. For example in a sanitary landfill, Compaction Density is affected by type of cover, the initial moisture content of the waste, type of landfill compactors used, number of passes by the landfill compactors, where it is measured (e.g. on side slopes), etc. Compaction in a sanitary landfill can be measured by multiple means, including aerial surveys, GIS etc. During collection, greater Compaction Density may be undesirable for certain recyclable materials such as glass.
Machines that reduce the volume of solid waste by crushing, compression or compaction. A landfill Compactor is a piece of heavy construction equipment with a blade (to push waste) and steel wheels with cleats (to minimize surface contact with waste and maximize pressure). It reduces volume of solid waste in a sanitary landfill by rolling over solid waste deposited on the surface of the sanitary landfill. A Compactor collection truck is equipped with a hydraulic ram and compactor plate that reduces volume by pushing and compressing wastes into the main body of the truck. Stationary Compactors contain a ram that pushes and compresses waste into a container or bale.
The end product of composting. It is a humus-like material that can be added to soils to increase soil fertility, aeration and nutrient retention.

Composting takes place under aerobic conditions, typically in an open pile (called a windrow) or in a tank or container (called in-vessel composting). See Aerobic Decomposition and Anaerobic Digestion.
Commingling of garbage, refuse or other material having unsuitable physical or chemical properties with recyclable materials or organic wastes, thereby rendering the recyclable materials or organic wastes unfit for further reuse, requiring processing prior to reuse, or decreasing their value for reuse.

A composting example is compost degraded by glass particles (a physical property) or heavy metals (a chemical property) present in the feedstock.
Action taken to investigate, describe, evaluate, correct and cleanup contamination from solid waste management facilities as prescribed in accordance with law, including CERCLA and RCRA.

Alternative Daily Cover is cover other than soil, such as spray slurries, tarps, foams, vegetative waste and ash. Daily Cover is cover applied at the end of each sanitary landfill operating day. Final Cover or Cap is cover comprised of layers of impermeable materials such as compacted clay, drainage materials, topsoil and vegetation applied over the top of a closed cell of a sanitary landfill to minimize the infiltration of rainwater and the production of Leachate.
See Roll Off Boxes.

Overt regulatory measure—usually in the form of a local governmental ordinance or official directive—mandating that solid waste, recyclable material or other material be transported to one or more designated sanitary landfills, transfer stations, materials recovery facilities or other solid waste management facilities. Flow Control has been significantly curtailed by Carbone. Some local governments have created financial incentives for haulers to bring wastes to particular facilities, and such methods (known as economic flow control) tend to withstand legal challenges. Contrast with “Facility Designation”, which is not regulatory in nature: for example where a service provider agrees, by contract, to transport or deliver waste or other material in accordance with the provisions of an agreement between the service provider and a governmental authority.

Franchisees may be required to secure licenses or permits in order to perform franchised services.
