Opportunities come not just from turning trash into treasure, but from engineering systems and products to make that a regular reality.

The opportunity
Reduce environmental degradation, conserve natural resources, decrease pollution, and create new economic opportunities by keeping materials in use for as long as possible.
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)
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!
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.
As a megatrend, the circular economy is not merely an environmental initiative; it is a powerful framework for economic growth, innovation, and resilience. Not to mention the fact that there is a huge amount of money to be saved and made!
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.
Europe leads on sustainability and participatory regeneration in mature cities, with a policy-driven focus on the circular economy and climate action.
From “Decoding Tomorrow: The Way Forward: #5 Construction: “For centuries, construction was about brute force. The next century will be about intelligence—smart materials, robotic precision, and data-driven design.”” (September 2025)
Sustainability & the circular economy . Green building is moving from a niche market to a core business imperative, with a growing focus on “design for deconstruction” to reuse materials and eliminate waste.
The Circular Economy (KLAW Industries) : This small business, supported by the EPA’s SBIR program, developed an innovative process for turning waste glass into a high-performance material that can replace traditional cement. The resulting concrete is not only stronger and lower in cost , but also boasts 97% lower carbon emissions compared to the cement it replaces.
Explore the circular economy: Make green building a core competitive advantage, not just a compliance issue. Actively explore and pilot the use of new, sustainable materials and adopt “design for deconstruction” principles to create long-term value.
