Dezeen and MINI World Tour: in our next movie from Eindhoven, Design Academy Eindhoven graduate Dave Hakkens shows us how his Precious Plastic recycling machines work and explains why he made the blueprints freely available online.

This portal is a brand of Vogel Communications Group. You will find our complete range of products and services on www.vogel.com

Hakkens designed a range of products to be produced using the machines, including a rotation-moulded waste paper bin, an injection-moulded spinning top and an extruded plastic lamp.

"We recycle just 10% [of waste plastic]," says Hakkens. "I wondered why we recycle so little so I investigated it. I went to all these companies and I realised that they don't really want to use recycled plastic. So I wanted to make my own tools so I could use recycled plastic locally."

Customers can choose from their EDM Polishing Stones Kit, General Purpose Polishing Stones Kit, White Aluminum Oxide Polishing Stones Kit, Silicon Carbide Polishing Stones Kit or Finishing Polishing Stone Kit. All assembled with three unique polishing stone formulations in either the Standard Kit which includes stones only or the Premium Kit which includes a 2oz bottle of Premium Stoning Oil and one compatible standard stone holder.

Like Hakkens' Phonebloks concept for a modular mobile phone, Precious Plastic is an open-source project and Hakkens hopes other designers will adapt and improve the machines over time.

"I developed these machines and I shared them on the internet," Hakkens says. "People can make them on the other side of the world and send some feedback and say, 'hey, maybe you can do this better'. In the end you'll have this set of machines and you can start a local recycling centre."

“Our new Multi-Polishing Stone Kits allow polishers to try an assortment of stone types specific to their individual needs whether it be EDM removal or final finishing,” says Annette Thompson, Boride’s Product and Project Manager.

"I made these machines based on industrial standards," says Hakkens. "But they are all made very simple so you can produce locally. Like a craftsman, you can start working with plastic."

“Not all polishing preferences are the same. These new kits make it easier for our customers to find the perfect stone for their specific application or desired finish.”

The Precious Plastic machines include a plastic shredder, an extruder, an injection moulder and a rotation moulder, which Hakkens made using a combination of new custom-made components and reclaimed parts he found at a scrapyard.

He says he got the idea for the project after visiting plastic manufacturing companies and discovering that they were reluctant to use recycled plastic.

"You can make whatever you want," he explains. "Everybody can use [the machines] to make whatever they want and set up their own production."

Boride Engineered Abrasives announced that they have added more polishing stone kits. Their new Multi-Polishing Stone Kits are now available.
