Project Circleg is an appropriate lower-limb prosthetic system designed for the needs of amputees in developing countries. By using recycled plastic waste in combination with simple production methods, the Circleg prosthesis can be produced locally and cost-effectively.

What makes it unique

Design

Project Circleg is design driven and therefore developed according to the needs and circumstances of the users.

Affordability

Project Circleg uses recycled plastic waste in combination with simple production methods in order to produce locally and cost-effective.

Sustainability

Project Circleg is based on the concept of circular economy and designed to work in a material cycle.

functionality & comfort

Adjustment

The adapters at foot and knee joint enable the individual adjustment to the user.

Swing-back-mechanism

A mechanism incorporated in the knee joint swings the leg forward while walking in order to prevent dangerous trip hazards.

Protection cap

The polycentric knee joint is equipped with a protection cap, which allows a kneeling position and protects the joint from dirt.

Ankle joint

The ankle joint allows a squatting position and therefore the use of a squat toilet.

Modularity & Customizability

The modular design ensures that the Circleg prosthetic system can be individually adapted to the user in terms of size and color. This allows expressing individual personalities through the Circleg prosthesis.

Problem

Why Project Circleg is needed

high demand

35 to 40 million people globally require prosthetic and orthotic services.

World Health Organisation

The demand for affordable prosthetics is high in many developing countries, however, most of existing prosthetic systems lack in terms of functionality, affordability and availability. Not being able to walk has a huge influence on physical, psychological, economic and social aspects. Without access to prosthetics, many individuals in need are confined to their homes and live dependent, excluded lives.

Valuable Resource

72% of the worldwide yearly produced plastic packaging ends up in landfills or nature.

Ellen McArthur Foundation: The New Plastics Economy

Landfills are often found in developing countries, as they have no capacities, resources and laws to set up an official recycling system. By using locally available recycled plastic waste, Project Circleg simultaneously tackles an urgent environmental issue (plastic pollution) and raises awareness for the environment in developing countries. The use of recycled plastic waste furthermore reduces material costs by up to 50 percent and adds value to the economy by transforming waste into a tradable resource.

  • Last but not least, the second founder of Project Circleg: @simonoschwald. Together with Fabian, Laura and Rahel he develops the new prototypes and when it comes to presenting Project Circleg, he's at the frontline. Apparently he likes green. And he also loves to travel!

  • Currently we‘re working on a new knee mechanism. Did you know, that a human knee joint is quite a complex construction? Nature is a pretty clever designer, we have to admit.⠀
