Australia’s 3D WASH Transforms Plastic Waste Into Water Pipes

The project team from 3D WASH and their 3D-printed plastic waste tubes.

Engineers at Australia's Deakin University have come up with a way to combine 3D printing and solar power that turns plastic waste pollution into practical water pipes for crisis hit regions.

3D printers are this generation’s wunderkind. 3D printed eggs are helping animal conservationists track turtle egg poachers in Central America, 3D printed running shoes are helping the clothing industry become more sustainable, and now a team at Deakin University has discovered yet another use for this versatile innovation. Dr. Mazher Mohammed and his team at Deakin University in Melbourne: because most printers can work with plastics, with a little bit of prepping they can be adapted to work perfectly to recycle plastic waste.

In particularly impoverished or remote areas, or those that have suffered destructive natural events, people usually live without proper waste disposal, and also with insufficient sanitation and sewage systems. The 3D WASH project, led by Dr. Mazher Mohammed, solves both those two issues in one go – their 3D printer presses plastic bottles, packaging waste and similar other plastics into tiny pellets and melts them down into plastic threads – the printer’s filament. In a second stage, tubes, joints and taps can be printed, many of the basic elements needed to build a functioning canalisation system.

The Benefits of 3D WASH

In order for the printer to be used in places where there is no electricity supply, it’s fitted with a photovoltaic element and in regions with enough sun can produce its own electricity and also save the energy produced in a battery. Another advantage to this project: solar energy and plastic waste are both available completely free and in the regions affected, both available in abundance.

After a successful crowdfunding campaign to finance the manufacture of the first printers, a primary trial run is planned this year on the Solomon Islands, at projects run by Plan Australia. “In the streets of Honiara, there is plastic literally everywhere. It clogs up the drains and flows out into the sea, killing marine life. Our aim is to turn this plastic into useful parts“: explained Tom Rankin, Plan Australia’s Manager for Water, Sanitation and Hygiene.

If the trial stage is successful, the project could be rolled out across a number of developing countries. According to Rankin:“If we can prove the concept and get the technology working well, it can be used across a raft of different fields, not just water and sanitation. Really, you’re only limited by your imagination about what you can print.”

The video below – that was originally used to raise funds for the project – tells you a little bit more about how it works.

3D-Printed With Ocean Plastic: The Running Shoe Making Big Strides

To help reduce the problem of plastic pollution, a new running shoe made with ocean plastic and using 3D printing technology is to hit the shelves by the end of 2017. Could this be a game changer for the sports industry?

Take Me Home, Plastic Roads

A new company has its eyes set on the world's roads. Through their 'magic formula', they want to minimise not just the environmental impacts of road building and maintenance, but also help reduce the plastic waste issue and, while they're at it, ensure that tax payers' money goes the extra mile. How do they do it?

How One Man Is Transforming A Million Plastic Bottles Into A Sustainable Village

One man's trash is another man's treasure. And in this particular case, that couldn't be more true. In the middle of a forest, on an island off the coast of Panama, an entirely new kind of village is springing up, with each house made of tens of thousands of recycled plastic bottles.

We all know that there's a problem. And the solution, unfortunately, isn't going to be all that simple. But now there is hope! The huge amounts of plastic waste floating in the world's oceans is one of the most pressing evironmental challenges of this century. But now there's a new technology which takes that waste and turns it into something new, in an eco-friendly, low-emission and non-toxic way.
