  2. Renewable polyethylene - Wikipedia

    en.wikipedia.org/wiki/Renewable_Polyethylene

    For these same reasons, it is also recyclable in the same recycling chain used by traditional polyethylene. Because it is part of the portfolio of high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) products, Green PE rapidly became an option for applications in rigid and flexible packaging, closures, bags, and other ...

  3. Closed-loop recycling - Wikipedia

    en.wikipedia.org/wiki/Closed-loop_recycling

    One goal of closed-loop recycling is to reuse materials in an identical role as before recycling. [ 3 ] [ 5 ] In contrast, open-loop recycling systems do not reclaim all of a resource. Whether by design or due to the physical and chemical properties of the materials recycled, some amount of resources is wasted, used to manufacture different ...

  4. Plastic recycling - Wikipedia

    en.wikipedia.org/wiki/Plastic_recycling

    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.

    Plastic recycling is the processing of plastic waste into other products. [22] [23] [24] Recycling can reduce dependence on landfill, conserve resources and protect the environment from plastic pollution and greenhouse gas emissions. [25] [26] [27] Recycling rates lag behind those of other recoverable materials, such as aluminium, glass and paper.

    en.wikipedia.org/wiki/Recycling_codes

    Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.

  7. Green solvent - Wikipedia

    en.wikipedia.org/wiki/Green_solvent

    Although the original process involves water, a green solvent itself, sc-CO 2 allows less waste materials. [57] In deep eutectic solvents, observations report that the higher the solvent's hydrophobicity, the higher the extraction efficiency of neonicotinoids from aqueous solutions, although the exact trend has not been established yet. [58]
