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. For the album, see Recycled (Nektar album). The three chasing arrows of the universal recycling symbol ...
Circular business models, as the economic model more broadly, can have different emphases and various objectives, for example: extend the life of materials and products, where possible over multiple 'use cycles'; use a 'waste = food' approach to help recover materials, and ensure those biological materials returned to earth are benign, not ...
Human composting is emerging as an end-of-life alternative that is friendlier to the climate and the Earth — it is far less carbon-intensive than cremation and doesn’t use chemicals involved ...
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.
Resource recovery can be enabled by changes in government policy and regulation, circular economy infrastructure such as improved 'binfrastructure' to promote source separation and waste collection, reuse and recycling, [5] innovative circular business models, [6] and valuing materials and products in terms of their economic but also their social and environmental costs and benefits. [7]
By contrast, human composting, like natural burial, is a natural process and contributes ecological value by preserving the body's nutrient material. [6] Some have argued that "natural organic reduction respects the human body and spirit, supports rather than sullies the earth, and works with nature rather than against it." [7]
Recycling can be carried out on various raw materials. Recycling is an important part of creating more sustainable economies , reducing the cost and environmental impact of raw materials. Not all materials are easily recycled, and processing recyclable into the correct waste stream requires considerable energy.
Plastic recycling is the processing of plastic waste into other products. [1] [2] [3] Recycling can reduce dependence on landfill, conserve resources and protect the environment from plastic pollution and greenhouse gas emissions. [4] [5] [6] Recycling rates lag behind those of other recoverable materials, such as aluminium, glass and paper.
