Q

scrap can be sorted easily using magnetism. if the metal is galvanised (coated with zinc) the zinc fully recyclable. if it stainless steel other metal mixed with the iron, such as chromium and nickel, can also be recovered and recycled.

Q

Scarity makes recycling especially desirable, and justifies the cost of removing insulation from electric wires, which are a major source of scrap. Pure metal can also be recovered from alloys derived from it, notably brass (which also contains quantities of zinc, and often lead) and bronze (which contains tin)

Q

Hardwood and softwood can be reused. However, the frequent need to remove ironmongery and saw or plane off damaged edges, can make the process costly

A

Timber

Q

Tyres are the primary source of recyclable material. These can be reused whole in certain application. They can also be ground into crumbs which have varied uses

A

Rubber
