Sourcing for Circularity

How do you choose the most sustainable material? Well, the more you know, the more you realize how complex and variable the answer may be. We’ve compiled a few open-access databases and analytics tools that go some of the way to guiding those choices, and thought about how we’d like to see them evolve.

The linear economy is, simply put, a one-way ticket from ‘take’ to ‘waste’. We extract a material, we make something from it, we sell it, use it, discard it. The circular economy, by contrast, is a transformative round-trip. It captures value at every cascade of a product’s life, repairing, reusing and recycling materials to keep them in circulation — and off the trash heap. But the transition to a circular and regenerative economy is especially challenging for the textile industry due to inherent material properties that inhibit recyclability.

In our own quest to be more circular, we also strive to be more conscious in our textile material choices, actively designing our products for disassembly and biodegradability. So, as part of our summer research project, PCH product designer, Gianna, teamed up with textile engineer, Konstantin Utz, to explore existing textile material databases in order to simulate a perfect circular material sourcing journey. And, as with so many points within the circular supply chain, they encountered both an encouraging increase in good initiatives (and intentions) but also a sorely fragmented and siloed solution landscape.

More than ever, we believe that intelligent, transparent and collaborative databases can facilitate the shift towards a circular economy by advancing future material production and processing. So, what would it look like? We identified the following hybrid features as key to our ideal, circular material database:

  • A more holistic overview of the product life cycle — from raw material to finished textile product. This would extend to providing material properties such as composition, wear and tear, decomposition, suitability of application and externalities in production, use and re-use.
  • Beyond merely connecting buyers and suppliers, the database should indicate material availability and identify potential bottlenecks, based on historical data, to boost supply chain reliability.
  • Use data analysis to offer intelligent alternatives and their substitution impact. By mining data from material properties and product requirements, one could provide material and process comparison functionality that tailors (and prioritizes) suggestions according to local sourcing, cascaded uses and closed loops, and drive regeneration throughout the value chain.
  • More AI-driven evaluation of the environmental impact of large-scale sourcing and extraction on biomes — such as the tundra, rainforest, temperate forests —to inform decisions on processes and the products themselves.
  • Seamless integration into the production and recycling process. One could streamline the process by providing renders, simulations and machining parameters for each life cycle step.
  • Fostering early and more transparent collaboration between buyers, sellers and recyclers would also drive efficiency, allowing the ultimate re-use of a product to be understood and considered from the start.

Closing the loop

Circularity is not a flickering trend. It continues to become more established as the necessary standard governing human production and consumption. But we will only be able to meaningfully shift to a circular economy if we connect different industries, technologies and people within the value net. Are you ready to connect with us?

The listed databases were carefully researched and compiled by Konstantin Utz and Gianna Moscoso Thompson for PCH Innovations. PCH Innovations is a Berlin-based, multi-disciplinary studio that develops divergent strategy and technology for regenerative systems.

We’re currently focussing on our circular robotics offering for repair, refurbishment and recycling. Do you have a project in mind? Let’s make something beautiful.
