Circular Economy & Product-Service Systems

Transform Your Business from Linear to Circular

The traditional ‘take, make, waste’ model is no longer sustainable. Resources are depleting, regulatory pressure is increasing, and customers are demanding more sustainable alternatives. Businesses that fail to adapt risk losing relevance in an economy shifting toward circularity.

At The Product Architects (TPA), we help companies transition from linear business models to circular, product-service systems (PSS). We guide organisations in identifying applicable Sustainable Development Goals (SDGs) and developing a roadmap to integrate circular economy principles into their core strategy. Our approach enables companies to reduce waste, unlock new revenue streams, and build long-term resilience.

A visual representation of how circular economy principles drive value. A central pyramid connects to five key areas: financial growth, environmental sustainability, human-centred innovation, market positioning, and operational efficiency.

Why Circular Economy & PSS Matter

Many businesses struggle with sustainability because:

  • Circularity seems difficult to implement, creating uncertainty about the most effective entry point.
  • Sustainability initiatives often lack a clear business case, leading to stalled execution.
  • Shifting to a service-oriented model requires rethinking ownership, which impacts business models, logistics, and customer relationships.
  • Regulatory pressure is increasing, pushing companies toward sustainable solutions whether they are ready or not.

By adopting a Product-Service System (PSS) approach, companies can create value beyond product sales by integrating services, ensuring product longevity, and embedding sustainability as a key business driver. This shift not only reduces environmental impact but also improves profitability, customer experience, and brand positioning.

Our Approach: From Linear to Circular in Six Weeks

Our structured six-week sprint helps companies transition to circular business models with minimal risk and maximum impact.

Week 1: Discovery & Research

  • Develop first prototypes and validate core assumptions

Week 4-5: Iteration & Validation


  • Gather customer feedback on circular offerings
  • Optimise business case for service-based revenue streams
  • Identify behavioural triggers to drive circular adoption

Week 6: Roadmap & Execution Plan


  • Deliver a structured implementation roadmap
  • Align business case with operational feasibility
  • Develop strategies to scale circular solutions and embed them in company operations

A structured roadmap for implementing circular business models. The process includes four key phases: discovery and research, circular sprint and prototyping, iteration and validation, and roadmap execution.
