Sustainable product design encompasses a systematic approach that considers environmental and economic aspects throughout a product’s life cycle. Sustainability and environmental impact have become a fourth key performance indicator (KPI) in product development, joining the traditional metrics of time, cost, and quality.
Environmental impacts
Adopting a design for sustainability framework positions companies at the forefront of sustainable development, aligning with Sustainable Development Goals and meeting the expanding expectations of consumers and investors alike. Within this context, the article navigates the strategic principle of ‘design for sustainability’
Defining Sustainable Product Design
Sustainable product design (SPD) is a multidimensional approach, intricately considering the inception to end-of-life. It is characterized by the intent to optimize the benefits and minimize the detriments across a product’s lifecycle, thereby embodying the essence of sustainability in the realm of the product development process.
The Capgemini Research Institute underscores the urgency of SPD in its study “Rethink: why sustainable product design is the need of the hour”, emphasizing the direct correlation between sustainable practices in design and enhanced revenue growth, alongside bolstered customer, and employee relations. To elucidate, SPD strategies are multifaceted:
Circularity: Emphasizing the longevity, reusability, and recyclability of products to foster a closed-loop economy.
Dematerialization: Reducing the material footprint of products and packaging to mitigate environmental impact.
Product Efficiency: Designing for minimal energy consumption during product use.
Next-Best Material Selection: Opting for materials with lower environmental impact without compromising product functionality.
Green Supply Chain: Sourcing materials and components that support sustainability and energy-efficient logistics.
Regenerative Approach: Creating products that replenish or renew ecosystems, rather than deplete them.
Systems Thinking: Assessing the product within a broader context, considering its social and environmental implications throughout its lifecycle.
Engineers and designers are increasingly cognizant of their role in environmental stewardship, seeking innovative ways to curtail waste and other greenhouse gas emissions. Decisions made at the design stage can determine a product’s repairability, upgradability, manufacturability, and recyclability, ultimately influencing up to 80% of its lifetime emissions.
The integration of sustainability into R&D and product design is a complex endeavor, necessitating a shift in resources usage, meticulous tracking of emissions and costs, and a sustainable mindset in every design decision. Sustainable design is not just about meeting the needs of the present; it’s about ensuring the capacity of future generations to meet their needs without compromise.
Incorporating ecoPLM from TT PSC into the SPD process allows for a systematic approach to manage environmental and economic aspects in the product lifecycle. It provides tools and indicators to measure and optimize environmental impact, making it easier for companies to track and reduce CO2 emissions from the design phase through to disposal. ecoPLM’s user-friendly interface aids designers in making informed decisions that align with sustainability goals, streamlining the workflow and enhancing the understanding of a product’s environmental footprint.
Understanding the Product Life Cycle
Understanding the intricacies of a product’s life cycle is pivotal to sustainable product design, as it encompasses the product sustainability entire journey from raw material extraction to disposal or recycling. This life cycle is traditionally segmented into five stages:
Material Processing: Where raw materials are extracted and processed. It is crucial to evaluate the environmental impact of the materials chosen for a project, including the positive or negative value of their entire Life Cycle Assesment (LCA). For instance, materials such as hardwood timber, plywood, MDF, bamboo, plastic, foam, and metal each have distinct LCA profiles that must be considered.
Design: The design of a product has the most significant influence on its life cycle and environmental impact. Almost 80% of a product’s impacts on environment are established at the stage of design. Life-cycle environmental requirements are decided upon in order to reduce resource depletion, energy consumption, waste generation as well as negative human and ecological consequences.
Manufacturing: Product lifecycle relies on manufacturing for its success. Businesses can enhance sustainability by considering environmental footprints throughout the value chain including design, manufacturing, use and disposal phases. During production process that involves using eco-friendly materials and reducing wastages minimally; manufacturers can significantly lower their products’ overall environmental impacts.
Distribution and Sales: Involving the transportation and sale of the finished product. This stage considers the environmental costs of logistics and the importance of designing for longevity to reduce the carbon, water, and waste footprints.
Product Use: The period during which the product is in use by the consumer. Designing for efficiency and considering the product’s entire life cycle, including the end-of-life stage, can significantly reduce environmental impacts.
End-of-life: The final stage, which involves disposal or recycling. This stage is critical for assessing the product’s overall sustainability, as decisions made during the design phase can affect the product’s repairability, upgradability, remanufacturability, and recyclability.
By incorporating ecoPLM, designers can navigate these stages with a systematic approach to managing environmental and economic aspects. ecoPLM provides a comprehensive set of tools and indicators to measure and optimize environmental impact. It aids in making informed decisions during the design phase, which is crucial for considering the environmental impact of each choice. With the ability to track and reduce CO2 emissions throughout the product lifecycle, ecoPLM supports companies in achieving their sustainability goals and streamlining their workflow with its user-friendly interface.
In practical terms, when designing a product for example, one must consider the material choice, sourcing materials, designing for longevity, biomimicry design, making process, and end of life. Each of these considerations’ feeds into the broader goal of reducing carbon emissions and ensuring a sustainable product life cycle.
The role of Life Cycle Assessments (LCA)
Life Cycle Assessments (LCA) play an integral role in sustainable product design by systematically evaluating the environmental impacts of a product throughout its entire life cycle. This assessment encompasses all stages, from raw material extraction to the manufacturing processes, usage, and disposal. It allows companies to measure their environmental footprint comprehensively and provides a critical starting point for identifying areas for improvement.
Environmental Impact Assessment: LCA is a science-based method that assesses four main factors: climate impact, resource usage, ecosystem changes, and pollution. This comprehensive view enables companies to pinpoint key areas where emissions can be reduced and circularity can be increased.
Strategic Optimization: By identifying hotspots, or stages with significant environmental impacts, LCA informs targeted improvements. For instance, it can reveal which phase of the product’s life cycle produces the most emissions, guiding designers to focus on those areas for greater efficiency and sustainability.
Sustainability Metrics Integration: Incorporating ecoPLM, LCA helps measure and optimize environmental impact during the design phase. It streamlines the workflow with a user-friendly interface, making it easier for companies to track and reduce CO2 emissions throughout the product’s life cycle.
LCA not only aids in meeting sustainability goals but also serves as a valuable communication tool for business leaders. It provides accurate proof of a product’s environmental impact, which can be crucial for complying with regulations, applying for tenders, and making honest sustainability claims. Marketing and sales teams can leverage LCA data to accurately communicate the environmental benefits of products to consumers, potentially capturing the green premium that comes with sustainable practices.
Supporting Business Strategy: Companies that embrace LCA gain insights into business partners and customers, developing more sustainable and tailored products that align with market demands. It also aids in achieving a secure and resilient supply chain, mitigating risks associated with resource scarcity, and ensuring business continuity.
Consumer Informed Decisions: LCA provides valuable information to consumers, enabling them to make more informed choices about the environmental impacts of their purchases. This transparency can foster long-term customer loyalty and drive potential revenue growth.
In summary, LCA is a cornerstone of sustainable product design, offering a systematic approach to assess and improve the environmental performance of products. By integrating LCA with ecoPLM, companies can make informed decisions that lead to significant reductions in CO2 emissions and enhance their competitive edge in a market increasingly focused on sustainability.
Strategies for Sustainable Product Design
Several strategies are linked up in sustainable product design aimed at minimizing environmental impacts while ensuring economic viability. These include dematerialization, which reduces the material footprint of products and packaging, next-best material selection where lower environmental impact materials (non-toxic, abundant, easily reproduced, rapidly renewable, low waste, recycled, recyclable, or biodegradable) are chosen as well. A green supply chain is also important by sourcing for materials and components that support sustainability and examine the energy used in logistics. To achieve this goal companies must have KPI’s put in place to measure ways of reducing environmental impact throughout life cycle e.g. through ecoPLM, to develop governance structures to underpin sustainability practice; then collaborate with other stakeholders who express commitment to greener practices. Through adoption of these strategies and enablers companies can set pace for innovation in creating sustainable products by considering the increasing need of consumers for green goods.
An example of sustainable product design in action is the development of plant-based substitutes for polyurethane foam used in car seats and mattresses.
