The manufactured products we use produce more than 10% of total greenhouse gas emissions. This is mostly from processing heat and producing the materials used in products.
The Transition Lab hosted a German engineer in a residency programme. The engineer, Lisa, had been working with a German orthopaedic device company on sustainabiltiy of their processes and products. But they had determined that they faced a wicked problem, so a job for Transition Engineering.
Lisa and Florian Ahrens worked through the Transition Engineering processes and came up with something that the manufacturer had not considered before. The most durable and best performing material for the devices is a very permanent plastic. There was no suitable alternative from the company, doctor or patient point of view. There is absolutely no way to recycle the permanent plastic, and no destructive disposal
The novel idea was to consider each item produced as a permanent object of value. Each devide is made for a specific patient for a specific problem. Rather than thinking of this as a one-off, keep a precise record of each item, and return it to a devide library. Then use AI to search the library for matches for future patients. Statistically, all the devices should find a number of future lives to improve, and should never be disposed of. Things of value, manufactured from permanent materials are an asset, if you build the measurement, catalogue, library, and search engine to provide the future value.
Brilliant!
The manufacturer is now working with TU-Chemnits to engineer the transition of their product system to a truely circular value model.
The Transition Lab welcomes residents from companies, local councils or other universities. Give us a couple of weeks and a really wicked problem, and we will help you with your first Transitioneering project. It would be even better if you take the Transition Engineering on line course first.
A paper describing the Transition Engineering process applied to this manufacturing problem was published in the journal "Sustainability" which is open-access.

Durable plastics are a sustainability challenge for healthcare products. Orthopedic products are regulated with strict specifications for human tissue interactions. Healthcare engineers and managers select plastic to meet the full range of material properties. Plastic is plentiful, low cost, and rel...
