Within just a few generations, plastic has already taken over the world, and while this material enabled a revolution in manufacturing and design, plastic has also managed to become one of the biggest menaces on the planet, thanks to its convenience and ease of production. And although commercial collection and recycling of plastics is getting better and more accessible, in many areas plastics end up in the dump instead the recycling facility, essentially burying this resource, which could be used to great effect if only the machinery were available to do so.

A few years ago, Kimberly wrote about the efforts of Dave Hakkens, who created a series of machines intended to put plastic recycling into the hands of the people. His Precious Plastics project promised free and open source blueprints, plans, and instructions for building these plastics recycling machines, which included a shredder, an extruding machine, an injection device, and a compression machine, and that information is now available on the website for anyone to download and put to work.

[...] The full set of Precious Plastic V2.0 information, which includes the CAD files and blueprints as well as posters, images, and instructions, is available as a free download under an open-source license, and detailed videos are available on the website to guide people through the process.

    The idea is great but:

    • The machines are very low volume and in reading the forums you can find that the motor in the specs is too feeble for the shredder.
    • With low volume, you would have a hard time selling either the shredded material or fiished products.
    • For finished products, the labor of collecting, sorting and cleaning the material, the cost of labor and parts for making molds and the production cost itself would make it difficult to make money, unless you are retired or still living at your parents' house
    • For shredded material, it is difficult to sell as it could be contaminated or mixed. Most recyclers either buy the bulk stuff or buy it pelletized, not shredded.

    A good step forward, but the machines need to be able to handle serious loads (i.e. at least a couple of tons per day) and the process of separation and cleaning need to be properly addresed in order to make money.

    Who said anything about making money? It would be profitable in some poorer countries, and the general idea is more about reducing waste than making competitive products.
