Project Circleg is a low-cost prosthetic leg system designed for the needs and circumstances of amputees in less developed countries. By using recycled plastic waste in combination with simple production methods, the Circleg prosthesis can be produced locally and cost-effectively.

What it makes 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’s system is designed to work in a material cycle. This enables a lasting preservation of value of the Circleg prosthesis.

high functionality

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 Circleg prosthesis is designed to be fully modular in order to repair or exchange broken parts. In addition it also allows the individual colour design of the leg prosthesis and therefore the possibility for the users to express themselves through the Circleg.

Problem

Why Project Circleg is needed

high demand

35 million people in the world need prostheses or orthoses.

World Health Organisation

The demand for low-cost leg prosthesis is high in many «less developed countries» (LDCs) and the existing prosthetic systems lack in terms of functionality, affordability and availability. Not beeing able to walk has a huge influence on physical, psycological, economical and social aspects. Many amputees are excluded from society and are not able to get a job and gain an income for their families.

Valuable Resource

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

Ellen McArthur Foundation: The New Plastics Economy

Such landfills are often found in less developed countries (LDCs), due to the lack of official recycling systems. As industrial designers we are driven by the notion of using plastic waste as a resource for meaningful products. Therefore the Circleg prosthesis is made of recycled polypropylene (PP) post-consumer plastic waste, which cuts the material costs down to 50%. It is reinforced with glass fibres to create a composite material that meets the high-performance requirements of a leg prosthesis.
