Depolymerization (or depolymerisation) is the process of converting a polymer into a monomer or a mixture of monomers. This process is driven by an increase in entropy.

Granulation is the process of forming grains or granules from a powdery or solid substance, producing a granular material. It is applied in several technological processes in the chemical and pharmaceutical industries. Typically, granulation involves agglomeration of fine particles into larger granules, typically of size range between 0.2 and 4.0 mm depending on their subsequent use. Less commonly, it involves shredding or grinding solid material into finer granules or pellets.

This project symbolizes plastic sequestration, net-zero construction, as well as collaboration within the community. The 'Y Hwb' earthen roundhouse relates to environmental justice as these houses reduce usage of environmentally harmful building materials, reuses plastic, and utilizes green roofs. This type of housing allows citizens to construct their own homes on an extremely low budget and live there for very ch

A recyclebot (or RecycleBot) is an open-source hardware device for converting waste plastic into filament for open-source 3D printers like the RepRap. Making DIY 3D printer filament at home is both less costly and better for the environment than purchasing conventional 3D printer filament. In following the RepRap tradition there are recyclebot designs that use mostly 3-D printable parts. This machine, license GPLv3, can be see in the Figure.
