Help from Mexico

A while ago I was looking for a machine builder that could help out making the plastic machinery. It got a great deal of response including this awesome video from Alex, from Mexico. Seriously, he never makes videos. But he knew how much I love them so he made one, have a look..

Starting filament maker

Delivering a prototype of the new extrusion to van alles wat ontwerp. They are going to focus on making filament with the extrusion. Keep an eye on the forums to follow the progress.


Research in Africa


With Precious Plastic we are trying to make plastic recycle machines that can be re-build all over the world. Everyone should be able to download the technical drawings and visit local workshops to get the materials and tools you need to make them. We take this quite serious and spend a lot of our development-time finding the right universal tools and materials that can be found everywhere in the world.

Last week we went to Ghana, Africa for research. Visit local workspaces, toolshops and machine builders. Finding out what materials are available, what technical knowledge they have and what kind of tools they use. In general they are less developed as the western world and have limited tools and materials available.However labor is much cheaper, this makes them use tools in a very different way and they are extremely good in reusing materials. Taking old broken products apart and sell the spare parts again, creating a huge market of universal components you can buy. –Specially from the automotive industry. It is very inspiring to see them at work and learn about their creative solutions.

Testing bicycle pressure

We’ve been exploring different ways to press plastic into molds for the injection machine. We always try to work with universal materials that can be found everywhere in the world, this one is made of old bicycles.

Shredder test

The first prototype of the plastic shredder. Unfortunately it doesn’t shred, looks more like a flatter. Probably the gaps in the knifes are to small. We’ll try out other versions next week.

Knifes for the shredder

We made the blades for the shredder prototype. Well actually the water-cutting machine did. Prototype online soon!



Slicing modular machines


Modular machines
One big task of Precious Plastic is developing machines that are more modular. Each machine will be divided in different modules/compartments/bloks *haven’t found the best word for it yet. We’re talking about parts like power supply, nozzle,  electronics, gearing etc. They are defined on which modules might be relevant to upgrade , customize in the future and where is the best place to connect them.. This is something we are defining right now, if you have any suggestions let us know!

Meet Kees, the machine builder

keesendaveOver the last month i’ve looking into all the submissions i’ve gathered from the previous post. – I was amazed by all the people that wanted to contribute to the project. After lots of spitting, thinking and skyping I selected Kees; a 53 year old unemployed machine builder from the Netherlands. He will be starting this week developing the machines and sharing updates in the forums. Below you can read more about him.

“My name is Kees 53 years old, 2 sons 24 en 26 and since last Sept. a proud grandfather of a girls-twin.”

€10.000 for open source development





had been working on machines to recycle plastic for a while, when soon after my other project Phonebloks exploded on the internet and Precious Plastic was set on hold. However, I still think this project has a huge potential and I am really keen on pushing it forward. Ihave a workshop, tools and materials to make it happen, however not the time or knowledge to get this done myself. I need a clever machine builder! That is why I am donating my prize money I won last year to someone that is able to do this.

Alex his injection machine

Recently I met Alex from Germany, he was inspired by the injection machine and used the outline to build is own machine. He already added some improvements, used a CNC milled mold and even gave a workshop with his machine.

The goal of this project is to develop machines that can recycle plastic and share them. With the blueprints online people all over the world can start building machines. So it makes me very happy to see other people building machines to recycle plastic as well.

Read his story below to find more information about his wonderful project and check out his machine!


Unique color everytime.
