I want to share my shredder called Simbiont. I hope we can all improve it and take inspiring ideas form it 🙂

Plastic waste’s granulator – suitable for use in fablabs, both in terms of the space it needs and its applications. It encourages the contribution of the community to fine grind of HDPE and PP in order to reduce energy consumption. It also makes the recycling process more efficient and transparent.

Thanks!! You can find more details of the project in the images below.

Looks nice!


Have you built a full working model yet? Do you plan to produce these for sale?


Being hand cranked is an attractive feature. I like the planetary gearing, that’s clever, how much mechanical advantage does it give / how much force needs to be applied to the handle?


What size plastic pieces can you put into it, will it take whole bottles? Or just smaller pieces like caps?
