For the last 50 years, economic growth has been tied to material consumption. Yet as we continue to extract and process more and more, we harm the very environment on which our economy relies.
Global resource extraction and processing, including fossil fuels, accounts for 90% of biodiversity loss and water stress – and contributes massively to GHG emissions. Four key materials are responsible for much of this harm: plastics, cement, steel and aluminium. The answer? Circularity.
Creating a truly circular economy means we can decouple production from primary resource consumption and avoid waste and pollution. By using alternative or renewable materials, optimising production, improving the lifecycle of materials and turning old materials into new, we can move towards an economy that does more with less – and generate profits in the process.
New profit pools are emerging with the rise of a circular bio-economy that offers renewable bio-based alternatives to the materials we use today. Alternatives such as nanocellulose made from wood pulp, that can be up to five times stronger than steel; or ‘new plastics’ made from plants or algae, that can be recycled more efficiently, or biodegrades easily at the end of life.
At the same time reuse, repurposing and recycling will maximise the useful life of extracted resources, such as recycled cement recovered from end-of-life concrete, and advances in battery recycling that can recover 80% of the lithium, and nearly all the cobalt and nickel, from used batteries.
In many of these we are approaching tipping points, as processes become commercially available due to technology improvements or the falling cost of renewable energy. In other instances, these tipping points are precipitated by policy, such as the commercial incentives created by EU restrictions on some single-use plastics.
And investors can be at the heart of this change. Innovations in technology and infrastructure will be key. Significant capex investment is needed. Already system-level solutions are moving at pace along the innovation curve as investors deploy capital, positioning to benefit from powerful market forces.
