Iron and steel are the world's most recycled materials, and among the easiest materials to reprocess, as they can be separated magnetically from the waste stream. Recycling is via a steelworks: scrap is either remelted in an electric arc furnace (90-100% scrap), or used as part of the charge in a Basic Oxygen Furnace (around 25% scrap). [20]
Textiles sent to the flocking industry are shredded to make filling material for car insulation, roofing felts, loudspeaker cones, panel linings and furniture padding. According to Earth911.com, "Metal hangers, while made of steel, can be difficult to recycle because their hooks can damage recycling equipment and some have a petroleum coating.
But while recycling experts say paper and metal products are fairly easy to recycle, plastics — even the No. 1 and 2 items Boiseans separate from Styrofoam and plastic film — pose more of a ...
[4] [5] [6] Recycling rates lag behind those of other recoverable materials, such as aluminium, glass and paper. From the start of plastic production through to 2015, the world produced around 6.3 billion tonnes of plastic waste, only 9% of which has been recycled and only ~1% has been recycled more than once.

Textile recycling is the process of recovering fiber, yarn, or fabric and reprocessing the material into new, useful products. [1] Textile waste is split into pre-consumer and post-consumer waste and is sorted into five different categories derived from a pyramid model.
One field of increasing interest where recycled materials are used is the manufacture of high-tenacity packaging stripes, and monofilaments. In both cases, the initial raw material is a mainly recycled material of higher intrinsic viscosity. High-tenacity packaging stripes as well as monofilament are then manufactured in the melt spinning process.
Contradicting studies have found that the raw source material (automotive tires) contains high levels of polycyclic aromatic hydrocarbons and metals such as zinc which have proven dermal, acute, and long-term health effects. The EPA is (as of fall 2015) investigating the health effects of exposure to crumb rubber and the initial results of this ...
