The traditional linear economy model operates on a simple yet unsustainable framework: extract raw materials, produce goods, use them, and then dispose of them. This product development life cycle has dominated industrial practices for decades, resulting in an over-reliance on finite resources and contributing to significant environmental damage, from resource depletion to increasing landfills and pollution.
However, with growing concerns over this model’s environmental impact, many businesses are shifting toward a more sustainable alternative: the circular economy. The circular economy is designed to keep materials in circulation for as long as possible, minimizing waste and maximizing the use of existing resources.
By integrating circular economy principles into the product development life cycle, businesses can reduce their environmental footprint, use resources more efficiently, and contribute to long-term sustainability goals.
This article will explore how businesses can incorporate circular principles into product development, rethinking traditional processes to create more sustainable, future-proof solutions. We’ll begin by outlining the 7 stages of the product development cycle before discussing how each stage can be adapted to support circular economy goals, like reducing waste and extending product life.

Understanding the circular economy
The circular economy aims to keep materials, components, and products in use for as long as possible, avoiding waste at every step. This model contrasts sharply with the linear economy, where products are typically discarded after use, leading to environmental damage and the depletion of natural resources.
The circular economy operates on three key principles:
- Design out waste and pollution. Products are designed for reuse and repair, not just for single use.
- Keep products and materials in use. This involves strategies such as repair, refurbishment, and remanufacturing.
- Regenerate natural systems. It also ensures materials and production processes contribute to environmental regeneration, not depletion.
The circular economy relies on waste management solutions that encourage the recycling and repurposing of materials. Organizations including the Ellen MacArthur Foundation have been crucial in championing these principles and pushing industries and governments, especially in Europe, toward adopting circular economy initiatives.
These efforts aim to reduce dependence on finite resources and build a sustainable future for businesses and society.
The product development life cycle in a circular economy
The product development life cycle typically involves several key stages: design, manufacturing, use, and end-of-life disposal. Each of these stages presents an opportunity to incorporate circular economy principles.
In a circular model, the focus shifts from simply delivering a product to ensuring that its entire life cycle – from raw material sourcing to post-use disposal – is optimized for resource efficiency and sustainability.
- Design. Products are created with longevity, repairability, and disassembly in mind.
- Manufacturing. Processes prioritize the use of recycled materials and minimize waste.
- Use. Products are durable and designed for multiple uses, encouraging consumers to repair rather than replace.
- End-of-life. Products are designed for easy recycling or remanufacturing, ensuring materials remain in circulation.
Effective product life cycle management (PLM) is essential for supporting these goals. PLM involves tracking a product’s entire life cycle and ensuring that each stage aligns with circular principles.
Life cycle assessment (LCA) tools help businesses evaluate their products’ environmental impact at every stage, making it easier to identify opportunities to reduce waste and improve sustainability. By incorporating these strategies, companies can shift from a linear model to a truly circular one.
The 7 stages of the product development cycle
The product development cycle is a structured process that takes an idea from concept to market-ready product. Each stage plays a crucial role in ensuring the product is viable, functional, and aligned with market demand.
By incorporating circular principles into this cycle, businesses can create products that are not only innovative but also sustainable, reducing waste and extending product life.
Let’s explore each of the seven stages and how they contribute to the overall success of a product while supporting a more sustainable future.
1. Ideation
This stage is where creativity and innovation come together to generate ideas for a new product. Businesses gather input from various stakeholders, brainstorm concepts, and explore different solutions to existing problems or gaps in the market.
Circular principles can be introduced here by considering the product’s life cycle from the start, with an emphasis on using sustainable materials and designing for longevity and reuse.
2. Research
Research is critical for validating ideas and understanding market demand. During this stage, businesses gather data on customer needs, market trends, and competitor products. This information helps determine if the product idea is viable.
When applying circular principles, research should also include the environmental impact of materials, production methods, and disposal options, ensuring the product aligns with sustainability goals.
3. Planning
The planning phase involves defining the product’s features, target market, and production process. A project roadmap is developed, outlining timelines, resources, and milestones.
Circular thinking here might include strategic planning for modularity, repairability, and the use of recycled or renewable materials, setting a foundation for a product that can be reused, refurbished, or responsibly recycled.
4. Prototyping
Prototyping brings ideas to life with tangible models or samples. This is where businesses test the product’s functionality, design, and feasibility. Multiple iterations are common during this stage.
To incorporate circular principles, prototypes should focus on minimizing material waste, improving efficiency, and designing for disassembly, making it easier to recycle or repurpose components later on.
5. Sourcing
During sourcing, businesses identify suppliers for the materials and components needed to manufacture the product. It’s essential to ensure that suppliers meet quality and cost requirements.
With circular principles in mind, businesses can prioritize ethical suppliers who use sustainable practices, offer recycled or biodegradable materials, and support the reuse of products or packaging.
6. Costing
Costing involves calculating the total expenses involved in producing the product, including materials, labor, and overhead. Businesses need to ensure the product can be made at a price that aligns with customer expectations and business goals.
While circular designs might initially seem costlier, they often save money in the long run through resource efficiency, reduced waste, and extended product life.
7. Commercialization
Commercialization is the final stage, where the product is launched into the market. This involves production, marketing, distribution, and sales. Incorporating circular principles during commercialization means promoting the product’s sustainability benefits, ensuring that packaging is recyclable or reusable, and providing options for customers to return or recycle the product at the end of its life cycle.
How to apply circular economy principles in the Product Development Life Cycle?
Incorporating circular economy principles into the Product Development Life Cycle involves rethinking traditional approaches to design, production, and end-of-life processes. By focusing on sustainability, resource efficiency, and waste reduction at each stage, businesses can create products that support long-term environmental goals while meeting consumer needs.
Here’s how to integrate circular thinking into every phase of product development.
Circular product design: Durability, repairability, and disassembly
Circular product design is one of the most important aspects of the circular economy. The design phase is where decisions are made that determine how long a product will last, how easy it is to repair, and how it will be disposed of at the end of its life.
To align with circular principles, companies should focus on three main design factors:
- Durability. Products should be built to last longer, reducing the need for frequent replacements. This not only saves resources but also enhances customer satisfaction.
- Repairability. Products designed with repair in mind can be easily fixed when something goes wrong, extending their useful life. For example, companies can reduce waste and encourage sustainable product design by making spare parts readily available and ensuring that products can be disassembled and reassembled easily.
- Disassembly. Products should be designed for easy disassembly at the end of their life, allowing components to be recycled or reused in new products. This requires careful planning during the design phase to ensure that materials can be separated without contamination or damage.
By focusing on these design principles, businesses can create products that support remanufacturing, reduce the need for virgin materials, and minimize resource consumption.
Circular business models and supply chain transformation
Transitioning to a circular economy also involves rethinking traditional business models. The linear approach to business is based on continuous production and consumption, with little regard for waste. Circular business models, on the other hand, focus on keeping products and materials in circulation, reducing waste, and maximizing resource efficiency. Some common circular business models include:
- Product-as-a-service. Instead of selling products outright, companies lease or rent them to consumers. This keeps products in use longer and allows them to be returned for refurbishment or remanufacturing.
- Leasing. Similar to product-as-a-service, leasing allows consumers to use a product without owning it. The product can be returned to the manufacturer for reuse or recycling at the end of its life cycle.
- Remanufacturing. Products are returned to the manufacturer, who refurbishes or rebuilds them for resale, extending their useful life and reducing waste.
For these models to succeed, businesses must transform their supply chains to support circular processes. This might involve sourcing sustainable materials, partnering with suppliers to reduce waste, and ensuring that closed-loop systems are in place to facilitate the reuse of materials. Adopting resource-efficient supply chains can help companies reduce their environmental impact and operational costs.
Circular initiatives in the product development process
Implementing circular economy principles into product development is not always straightforward. However, businesses can take several practical steps to get on the right path:
- Use recycled materials. Incorporating recycled materials into the manufacturing process reduces the need for virgin resources and helps close the loop on waste.
- Design for longevity. Creating products that are durable and can be easily repaired or upgraded reduces the need for frequent replacements.
- Optimize energy consumption. Reducing energy consumption during the manufacturing process and using renewable energy sources helps minimize the environmental impact of production.
- Assess environmental impact. Conduct a thorough LCA to identify opportunities for reducing waste and emissions across the product’s entire life cycle.
These sustainable practices can help businesses gradually transition to a circular model, benefiting both the environment and their bottom line.
How to handle challenges in a circular product development life cycle?
While the benefits of circular product development are clear, businesses face several challenges when making the transition:
- High upfront costs. Redesigning products and reconfiguring supply chains to support circular processes can be expensive in the short term.
- Regulatory hurdles. Navigating regulatory frameworks can be complicated, especially in industries with strict product safety standards.
- Stakeholder resistance. Convincing stakeholders to invest in circular initiatives can be difficult, particularly when the benefits are long-term and not immediately visible.
To overcome these challenges, businesses need to focus on long-term value creation. While the upfront costs may be higher, the savings from reduced resource use, carbon footprint, and new revenue streams can offset these investments over time. Communicating the benefits of circular practices to stakeholders will help gain their support.
The role of policymakers and industry in shaping a circular future
Governments can incentivize circular product development through regulations, subsidies, and standards that encourage companies to adopt more sustainable practices. For instance, the European Union has been at the forefront of the circular economy movement in Europe. Its Circular Economy Action Plan initiative sets a roadmap for making the EU’s economy more sustainable.
Regulatory frameworks like these that promote circular product design and resource efficiency help policymakers ensure that businesses prioritize sustainability.
Collaboration between governments, industry, and consumers is also crucial for building a sustainable future. Working together, these groups can create an economy that prioritizes long-term sustainable development over short-term profits.
A path towards sustainability in product development life cycle
Integrating circular economy practices into the product development life cycle is essential for building a more sustainable, resilient future. Businesses can reduce their environmental impact by focusing on durability, repairability, and resource efficiency while creating long-term value for themselves and their customers.
Circular practices are not just beneficial for the environment – they make good business sense. Companies that invest in sustainable design, manufacturing, and supply chains can reduce costs, open up new revenue streams, and meet growing consumer demand for eco-friendly products.
As we rethink traditional approaches to product development, the circular economy offers a promising path forward that benefits businesses and the planet.
