Precious Plastic is an open hardware plastic recycling project and is a type of open source digital commons project. [12] It relies on a series of machines and tools which grind, melt, and inject recycled plastic, allowing for the creation of new products out of recycled plastic on a small scale. [13]
Approximately 6.3 Bt of this was discarded as waste, of which around 79% accumulated in landfills or the natural environment, 12% was incinerated, and 9% was recycled - only ~1% of all plastic has been recycled more than once. [7] More recently, as of 2017, still only 9% of the 9 Bt of plastic produced was recycled. [39] [40]
The process would utilize about ten plastic bags to make each of their bags[1,3], but even with this achievement societal norms were still against them for it was improper for women to be working and created ridicule was seen as improper to be digging through trash instead of doing typical household work and because they were all women, it also ...
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.

Plastic recycling is the processing of plastic waste into other products. [22] [23] [24] Recycling can reduce dependence on landfills, 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.
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]
Rothy's products are made from recycled plastic water bottles and post-consumer recycled materials. [29] During the manufacturing process, the water bottles are hot washed and sterilized. Chips of plastic are melted down into pellets, stretched into fibers, and given air treatment until they entwine.
