Converting waste materials into new products This article is about recycling of waste materials. For recycling of waste energy, see Energy recycling. "Recycled" redirects here.

Plastic recycling is low in the waste hierarchy, meaning that reduction and reuse are more favourable and long-term solutions for sustainability. It has been advocated since the early 1970s, [36] but due to economic and technical challenges, did not impact the management of plastic waste to any significant extent until the late 1980s. The ...
Mixed waste can also be defined as a type of waste which includes recyclable materials and organic materials. [21] Some examples of mixed waste in this context include a combination of broken glassware, floor sweepings, non-repairable household goods, non-recyclable plastic and metal, clothing, and furnishings.
Materials for recycling may be collected separately from general waste using dedicated bins and collection vehicles, a procedure called kerbside collection. In some communities, the owner of the waste is required to separate the materials into different bins (e.g. for paper, plastics, metals) prior to its collection.
Waste valorization, beneficial reuse, beneficial use, value recovery or waste reclamation [1] is the process of waste products or residues from an economic process being valorized (given economic value), by reuse or recycling in order to create economically useful materials.
By reducing the production and use of raw materials, closed-loop recycling minimizes harm to the environment and discourages resource depletion. [5] In contrast, open-loop recycling is the process by which a product is recycled but has to be mixed with raw materials to become a new product, typically leading to downcycling. [1]
One way to address this is to increase product longevity; either by extending a product's first life or addressing issues of repair, reuse and recycling. [2] Reusing products, and therefore extending the use of that item beyond the point where it is discarded by its first user is preferable to recycling or disposal, [3] as this is the least energy intensive solution, although it is often ...
For example, scrap recycling diverts 135 million short tons (121,000,000 long tons; 122,000,000 t) of materials away from landfills. Recycled scrap is a raw material feedstock for nearly 60% of steel made in the US, almost 50% of the copper and copper alloys produced in the US, more than 75% of the US paper industry's needs, and for 50% of US ...
