Precious Plastic

Precious Plastic is an open hardware plastic recycling project and is a type of open source digital commons project. The project was started in 2013 by Dave Hakkens and is now in its fourth iteration. 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.
History.
In 2012, Dave Hakkens started working on Precious Plastic as a part of his studies at the Design Academy in Eindhoven. The project was released in 2013 as Version 1.0.
The work on version 2 was started in 2015 and was released in March 2016. In 2016, Precious Plastic also created a marketplace called Bazar for selling machines and products targeted to DIY designers to recycle plastic.
The team started working on version 3.0 from early 2017 and was launched in October 2017.
In May 2018, Precious Plastic received the Famae award of €300,000 to further develop the project. The city of Eindhoven also provided them a big workspace free of charge. In October 2018, Precious Plastic project officially opened its doors at the VDMA building in Eindhoven. The work on Version 4.0 was started in September 2018.
In 2019 Hakkens and Precious Plastic were involved in disagreement over whether to burn or recycle plastics collected from the oceans.
The version 4, which includes business models and starter kits for creating recycling systems, was announced in January 2020.

Precious Plastic is an open hardware plastic recycling project and is a type of open source digital commons project. 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. The project allows individual consumers to set up "their own miniature recycling company". 
The project is composed of more than 40,000 people in over 400 work spaces, either remotely or on site in the Netherlands.
