SALVAGE

The act of obtaining a secondary material through collection, sorting, etc.

SC

Steel cans.

SCRAP

That portion of solid waste which can be economically recycled.

SD

Steel drums.

SECONDARY MATERIAL

See: Post consumer material; Post industrial material.

SEPARATION

See: Source separation.

SG

Specialty grades, paper.

SHREDDER

Equipment that is built for size reduction of waste - they can be single-shaft, dual-shaft, or several-shafts. They can be low speed, utilizing multiple rotors with “shredding” teeth that grab material and rip it apart, with a series of evenly spaced cutting knives that cut material as it passes through (such as traditional paper shredders). The final shred size is pretty much determined by the knife assembly With the exception of most paper shredders, this type of machinery will accept very large chunks of scrap. Our primary machinery can be called a “shredder”, because it can do the same job but with a few additional benefits.

SHREDDING

Size reduction by shearing action.

SHREDDING EQUIPMENT

Machinery designed for the destruction or size reduction and material handling of various materials. This includes conveying systems, metering systems, control interfaces, separation equipment and, of course, shredders

SHREDDING TRUCK

Trucks equipped with a shredder, typically used in the document destruction industry. They allow secure document destruction “on-site”.

SHT

Stainless, high temperature steel.

SINGLE-STREAM RECYCLING

Single stream means one collection container for all paper, glass, metal and plastic recyclables. The materials are then separated and processed at a MRF and sold to end-markets.

SM

Special metals.

SOLID WASTE

Nonsoluble, discarded solid materials, including sewage sludge, municipal garbage, industrial wastes, agricultural refuse, demolition wastes and mining residues.

SOLID WASTE MANAGEMENT

The handling of activities which provide for the collection, separation, storage, transport, transfer, processing, recycling, incineration, treatment and disposal of solid waste.

SOURCE REDUCTION

Reducing the quantity of waste which in turn lessens the amount of material that enters the waste stream.

SOURCE SEPARATION

The sorting of specific waste materials prior to their collection or deposition into a collection container.

SPECIAL WASTES

Any waste requiring special handling such as scrap tires, used motor oil, hospital wastes or household hazardous wastes.

STEEL CAN

A rigid container made exclusively or primarily of steel. It is 100% recyclable.

SWEATING FURNACES

Furnace in which metals are separated by melting at different temperatures.
