Startup Turns Recycled Plastic into 3D Printing Filament

Reflow converts recyclable plastic into 3D printing filament using open source technology. Reflow filament is made from recycled PET bottles collected in developing regions, and revenues from the filament go back to the waste collectors who gather these bottles, which the company claims can increase their income by up to 20 times.

Jasper Middendorp, Reflow CEO, visited recycling centers in Nairobi, Kenya last year and saw how the waste collection, trade and recycling systems work. He saw that waste collectors collect plastic all day and receive very little money for it. They may earn 10-15 cents per kilogram and, for many, that’s their family’s only income stream. Meanwhile, a kilogram of 3D print filament costs around $30.

“That’s a huge disparity, and the reason for the focus on plastic recycling and 3D printing,” he told Plastics Technology. “Reflow is looking to leverage the exponential growth in the 3D printing market to create value from the waste plastic being collected and to flow that value back into waste picker communities and local manufacturing in developing regions.”

The company has a big task ahead: it aims to turn the growth of 3D printing into income for more than 40 million waste collectors worldwide that collect waste for a living, earning less than $2 a day. But the company believes the impact it will have on these communities and on the environment is significant: every kg of filament sold results in the removal of 120 bottles from the streets and $3 additional income for waste collectors. The company’s aim is to sell 5000 kg of filament in the first three years. If they achieve this goal, waste collectors’ incomes will increase by $200,000 and 6 million plastic bottles will be removed from the street.

Currently, Reflow’s material comes from waste collectors in Dar es Salaam, Tanzania who pick plastic bottles by the road or at designated locations (bars, hotels etc.) and bring them to a satellite collection point or central facility. The plastic is weighed, examined and the waste collector is paid.

Reflow filament is suitable for all 3D FDM printers that are capable of printing in a range of 435°F-455°F, although a heated bed is recommended. Reflow filament can be used in any application where other ABS, PLA and PET filaments are used.
