What this domain covers
The circular economy focuses on designing waste out of systems, extending product life, recovering materials and creating economic value from reuse and regeneration. It connects product design, manufacturing, logistics, materials and resource strategy.
What belongs here
- Circular product design
- Recycling and materials recovery
- Resource efficiency
- Remanufacturing
- Waste-to-value systems
- Product lifecycle redesign
- Closed-loop supply chains
Why it matters
Resource constraints and changing economics can make waste a design problem rather than an unavoidable outcome. Circular systems create opportunities to rethink materials, products, ownership and supply chains from the beginning.
Opportunities come not just from turning trash into treasure, but from engineering systems and products to make that a regular reality.

In Jim’s words
From “Decoding Tomorrow: 30 Megatrends - #8 The Circular Economy: “Opportunities come not just from turning trash into treasure, but from engineering systems and products to make that a regular reality.”” (July 2025)
What’s it all about? Essentially, the way we produce and consume goods is undergoing a fundamental shift. For decades, our economy has largely operated on a linear ” take-make-dispose ” model, leading to significant waste and depletion of natural resources. Everything we build is thrown away; there is nothing in the design of the product itself that presumes reuse and recycling. However, that is changing, and a new paradigm is emerging: the circular economy . This regenerative system is designed to eliminate waste, keep products and materials in use, and regenerate natural systems, presenting a strategic imperative for the coming decade and unlocking trillion-dollar opportunities. Sustainability is moving from corporate responsibility to core business strategy, despite political pushback. The circular economy, which involves turning waste streams into value, represents one of the greatest untapped opportunities of our time - a multi-trillion dollar opportunity!
From “Decoding Tomorrow: 30 Megatrends - #25 Urban Reimagination : “Beyond smart, we are building living cities: integrated ecosystems designed for a resilient, equitable, and profoundly human future.”” (July 2025)
Part of the reason for the trend is that simply, we simply need to rethink how cities function in light of scarce resources. Cities consume 75% of extracted natural resources and generate up to 80% of greenhouse gas emissions, making a transition from linear ‘ take-make-waste’ models to circular resource flows an imperative for survival. Circular Metabolism . Urban agriculture, through technologies like vertical farming and aquaponics, is re-localizing food production, while circular economy models are transforming waste streams into valuable resources.
