Brands looking to be environmentally-friendly must take sustainability into account throughout their product’s lifecycle, including cutting energy consumption by designing more energy-efficient products.
Manufacturers are increasingly realizing the importance of sustainability to their business strategies; however, this shift often meets with resistance due to perceived costs.
The Basics
Sustainable product development has become an indispensable skill set in many engineers’ toolboxes. This process involves taking into account every element that may impact the environment from material sourcing and production through shipping, storage, use and end of life disposal. Engineers should make sustainability an integral component of every stage of product design while companies should equip their engineers with digital tools necessary for sustainable design.
One of the key aspects of sustainability is materials minimization. This involves finding ways to use less material without compromising quality or functionality; its aim should be to eliminate anything which does not advance product fulfillment and fulfill customer needs.
Another key element is to determine whether a company can find greener alternatives to the materials it currently utilizes, such as recyclable metal or sustainable wood products. Furthermore, it’s also essential that any product abandoned after use be assessed for any possible impactful outcomes on the environment.
Engineers should consider ways their designs could be altered to reduce environmental harm caused by products made of polymer chains that remain intact after use, polluting rivers downstream. Engineers need to take into account how this design could be changed to avoid such harm to the environment.
As part of efforts to protect the environment, it’s also crucial that products become more durable and reusable, thus decreasing waste production and the need for new raw materials to be produced.
Implementing sustainable product design into R&D processes presents several unique challenges, the greatest being changing engineering culture. This involves educating R&D staff about its importance and changing formal performance-management systems accordingly, training new capabilities such as resource cleansheeting or life cycle analysis, or both; but companies who invest in this effort will experience greater R&D efficiency as well as increased customer and investor satisfaction as a result of this investment.
Assessing Materials and Eco-friendly Alternatives
At the core of sustainable product design is selecting materials. Manufacturers should look for those which can quickly be replenished or recycled when their product has reached the end of its life. Woods return after harvesting; metals can be melted down for reuse; plastics biodegrade; while many companies now provide eco-friendly alternatives to chemicals used during manufacturing processes.
Product designers should incorporate sustainability principles into product design by minimizing the number of parts and components found in a finished product. As more parts increase energy usage for production and assembly, manufacturers may wish to design components with self-assembling features or modularity to reduce assembly time while making reconfiguring easier for customers reselling or refurbishing it as per individual customer needs. Modularity is also key element of sustainability initiatives like Cradle to Cradle Design certification or Emotionally Durable Design (EDD).
Product development should also consider sustainability during transportation and distribution by creating products with as small an environmental footprint as possible, using eco-friendly shipping systems and methods, or opting for lightweight packaging materials. This can be accomplished through designing products specifically for shipping at their minimum form factor or using lightweight packaging materials where applicable.
Engineers should incorporate environmental considerations early in product design processes for maximum impactful sustainable practices. This is particularly applicable in high-impact sectors like electronics and transportation where there may be numerous opportunities to implement more eco-friendly practices.
Manufacturers that wish to incorporate sustainability into the R&D process face the difficulty of breaking down silos between engineering disciplines and integrating it into existing processes, which requires creating a center of excellence that oversees sustainability and collaborates with leaders of each business unit to integrate sustainable product development as part of formal R&D processes. With such an approach in place, companies can turn sustainable product development from corporate aspiration into reality while reaping all its advantages - from reduced environmental impacts associated with raw material sourcing all the way through to reduced end of product lifecycle impacts - realizing full benefits associated with sustainable product development!
Streamlining Manufacturing for Reduced Environmental Impact
Sustainability was long seen as an optional add-on when it came to product development units, but recently has become an integral component of business strategies and product quality requirements. Companies are realizing the immense power of making products more eco-friendly from day one by including sustainability into their design processes and engineering tools from day one.
Integrating sustainability into engineering processes requires new ways of working, so as to ensure sustainability goals are considered throughout product development, and teams have access to tools necessary for doing so. At Hannover Messe 2022, our research collected perspectives from several engineers to better understand how they are currently doing this and find potential areas of improvement.
While all interviewees acknowledged having policies around sustainability, none had linked these policies systematically with engineering design requirements. Based on our discussions of the interviews, we developed a profile model for managing sustainability integration into requirements (PROSEQ) and identified improvement actions spanning documentation, processes and routines, methods tools competencies as well as sustainability perspectives.
All interviewees stressed the need for clear communication and a structure for sustainability-related requirements. Company 2 suggested setting up a system where an unofficial specialist in sustainability would be consulted when decision boards or designers had queries regarding SPD tools/assessments and help select improvements that do not hinder meeting other product specifications.
Many of those interviewed described a need for training on how to utilize new tools and processes that incorporate sustainability, from short introductions for senior managers through more in-depth life cycle analysis training for design engineers.
One of the more challenging aspects of engineering sustainability lies in finding a balance between competing goals and priorities. Engineers are expected to create products that satisfy multiple requirements such as circularity, clean air/climate protection, water/soil stewardship or circularity; sometimes these goals even conflict or compete against one another - for instance using wood instead of concrete may lower carbon emissions but could increase electricity usage; nonetheless we must remain open-minded toward all benefits offered by sustainability while considering its effects over an entire product lifetime if we hope to create true business value and achieve true business value.
Lifecycle Analysis
Lifecycle analysis can be an extremely powerful tool in engaging stakeholders in sustainable product design. It evaluates the environmental impacts of products or services throughout their lifetime - from extraction of raw materials, production and use through to end of life disposal and potential strategic improvements such as energy saving or emissions reduction opportunities - providing valuable information for eco-design.
LCA can often be perceived as being complex and costly, due to the many different tools it requires for calculation of energy consumption and emissions. But this doesn’t have to be true. There are ways LCA analysis can be simplified so even small businesses can reap its power and benefits.
An LCA of a cloth diaper could reveal that it is more eco-friendly than its disposable counterpart, since carbon footprint calculations for products depend not only on what raw materials were used during production but also how transport routes between factory and storage warehouse were utilized as well as distribution to customers and disposal methods for when the final product is no longer necessary.
Thus, companies can make significant reductions to their environmental impact by making minor modifications to how they produce products or services, and also improve their reputation by becoming more appealing to an increasing number of consumers and investors who take note of a company’s sustainability policies.
LCA provides another advantage for businesses: It can quickly identify and prioritize areas of environmental concern for them. For instance, businesses might discover they’re using too much energy during production processes or producing too much wastewater waste - both factors in which could reduce costs significantly by switching out sustainable and eco-friendly materials for use instead.
The three case companies reported establishing interaction projects with waste companies and creating training programs on circular economy (CE), to close knowledge gaps and enable its implementation. Furthermore, they are actively approaching their customers with sustainable and circular solutions for product components.
In Conclusion
Sustainability is no longer an optional add-on for businesses; it’s now a fundamental component of product quality requirements and an integral part of business strategies. Sustainable product development involves taking into account every element that may impact the environment, from material sourcing and production through shipping, storage, use, and end-of-life disposal. Engineers should make sustainability an integral component of every stage of product design, and companies should equip their engineers with digital tools necessary for sustainable design. By incorporating sustainability into their engineering processes, companies can turn sustainable product development from corporate aspiration into reality while reaping all its advantages, from reduced environmental impacts associated with raw material sourcing all the way through to reduced end-of-product lifecycle impacts.
Sustainability can be achieved through finding greener alternatives to the materials currently utilized, such as recyclable metal or sustainable wood products. It’s also essential that any product abandoned after use be assessed for any possible impactful outcomes on the environment. Furthermore, implementing sustainable product design into R&D processes presents several unique challenges, such as changing engineering culture. However, companies who invest in this effort will experience greater R&D efficiency as well as increased customer and investor satisfaction as a result of this investment. In conclusion, sustainable product development must be a top priority for businesses who wish to remain competitive, reduce their environmental impact, and meet the growing demand for eco-friendly products.
