Conceptualising the technosphere of a circular economy through a living systems metaphor

This paper explores the move to a circular economy through the metaphor of a living system: a forest. The technosphere of a circular economy is an entirely human-made and managed realm. This research aims to explore how a common understanding of how a forest works can be used to conceptualise the products, components and materials that circulate in the technosphere as "fruit". This exploration entails four aspects of the metaphor: (1) the recipient needs to know what it is "eating", (2) the fruit needs to be "non-toxic" for the recipient, (3) the fruit needs to be nutritious and, (4) the wider system needs to be able to "metabolise 2 the nutrients". This metaphor allows for a more interconnected and holistic understanding of different economic and societal actors, their relationships and overall productivity. The nature of many materials in the technosphere prompts consideration of issues of standardisation, complexity, disclosure, and liability together with intellectual property rights. However, special attention and/or treatment is needed for materials that can be considered "substances of concern", which ideally would be designed out or carefully managed to avoid exposure. Furthermore, the paper explores the "nutritional value" of technosphere materials, emphasising the need for increased product longevity, through strategies such as design for disassembly and the right to repair. Finally, to allow the wider, open system to benefit from diverse inputs, it requires further decentralisation of supply chains, enabling accessibility of inputs to more informal or smaller-scale economic entities and fostering local creativity. To support this change, concepts related to nutrient stock maintenance and total product liability are addressed.
