From waste to value

At our core, we have long understood the urgency of transitioning from the traditional linear economy to a circular one. After years of working within the circular economy landscape, it’s clear that the stakes have never been higher, but the opportunities have never been greater. This isn’t just about solving environmental problems—it’s about creating a future that balances economic growth, environmental responsibility, and job creation. 

The shift to a circular economy is more than a necessity; it’s a movement that is reshaping industries, redefining how we think about resources, and presenting tremendous career opportunities for professionals ready to lead the change.

The linear economy is failing us

The linear "take, make, dispose" model may have driven industrial growth in the past, but its flaws are now glaringly obvious:

Finite resource depletion: The linear economy extracts resources faster than they can regenerate. Fossil fuels, rare earth metals, and other raw materials are being depleted at unsustainable rates, leading to scarcity, habitat destruction, and geopolitical tensions.

Mountains of waste: Each year, millions of tons of waste are generated, much of it non-biodegradable. Plastics, for instance, pollute waterways, oceans, and ecosystems, with microplastics even infiltrating our food systems.

Climate change: Energy-intensive production processes driven by fossil fuels make the linear model one of the biggest contributors to greenhouse gas emissions, driving climate instability.

Short product lifecycles: Planned obsolescence ensures products are replaced rather than repaired, creating a cycle of overconsumption and waste. 

These issues don’t just harm the environment—they disrupt economies, impact human health, and jeopardize the wellbeing of future generations.

Why circular economy is the future

The circular economy offers a transformative alternative by designing waste and inefficiency out of the system.

Having partnered with businesses across industries, we’ve seen how circular practices can redefine value creation.

At its core, the circular economy is built on three key principles:



Eliminate waste and pollution
: Redesign systems to prevent waste from being generated in the first place.

Keep materials in use: Promote repair, refurbishment, and recycling to extend the lifecycle of products and resources.

Regenerate natural systems: Transition from extraction and degradation to practices that restore ecosystems and biodiversity. 

The benefits extend beyond environmental gains:

Resource efficiency: By reusing and recycling materials, companies reduce reliance on finite resources, minimizing costs and environmental impact.

Waste reduction: Waste becomes a resource, significantly reducing landfill dependency and ocean pollution.

Economic resilience: Circular systems are less vulnerable to global supply chain disruptions and raw material scarcity.

Innovation and job creation: From product design to material recovery, the circular economy creates dynamic career paths and spurs technological advancements.

Our inspiration within Circular Economy comes from across a number of organisations and international standards that we look to.

Here are our top 3 favourites - check them out and get to know them!

01.

Cradle to Cradle Products Innovation Institute

A non-profit organization powering the shift to a circular economy, by setting the global standard for materials, products and systems that positively impact people and the planet. 

02.

Ellen Macarthur Foundation

An international charity that develops and promotes the circular economy to tackle some of the biggest challenges of our time, such as climate change, biodiversity loss, waste and pollution.  

03. 

Platform for Accelerating the Circular Economy

A global collaboration platform for key public and private leaders to share a vision, best practices and overcome challenges to scale the circular economy together. 

Job market in the circular economy

Globally, the circular economy is projected to create a net increase of 7 to 8 million jobs by 2030, particularly in roles focused on sustainability, waste management, and resource recovery (International Labour Organization). 

From our work in this field, we’ve observed key trends in workforce demand:

Product designers and engineers: developing long-lasting, repairable products that can be eventually recycled or upcycled.

Bio-innovators: turning food or agricultural waste and used oils into renewable energy sources or green chemicals.

Sustainability supply chain managers: Optimizing resource flow for maximum efficiency and minimal waste.

Sustainability marketers and strategists: communicating the value of circular solutions and creating new business models like leasing and product-as-a-service.

Building a career in the circular economy

Transitioning into the circular economy is not only feasible but also highly rewarding. For professionals looking to make a difference, here are some key steps:

Understand circular principles: gain expertise in lifecycle analysis, sustainable design, and resource recovery.

Upskill: certifications in sustainability, renewable energy, and circular practices can give you an edge.

Leverage existing skills: many roles in engineering, procurement, and logistics align naturally with circular economy practices.

Engage with the community: join professional networks, attend events, and connect with organizations at the forefront of circular innovation.

Our role in driving the circular economy

Having worked extensively within this space, we’ve seen firsthand the transformative potential of circular practices. Whether collaborating with businesses to redesign supply chains, supporting bioenergy initiatives, or helping companies transition to circular models, our mission is to bridge the gap between innovation and impact.

The circular economy isn’t just a vision for the future; it’s a tangible pathway to solving some of the world’s most pressing challenges. It’s about creating systems where waste becomes value, industries thrive sustainably, and future generations inherit a healthier planet. 

Now is the time to act. The circular economy isn’t just about reshaping industries—it’s about building a legacy.
