Using Software to Design Sustainability into the Manufacturing Process

As the world of manufacturing gets increasingly more high-tech, there are a growing number of tools that can help companies focus on reducing energy and materials use at every stage from concept to production.

A webcast convened by yesterday brought together three experts who are focused on various aspects of sustainable design and manufacturing to share what's possible and what's already happening on factory floors around the world.

"The secret reason for sustainble design is that it reduces costs," said Patrick Coulter, the Chief Operating Officer at Granta Design and one of the presenters on the webcast.

He offered two examples: Walmart and the Dyson Airblade hand dryer. Both are examples of how designing with sustainability in mind save significant costs -- whether in terms of energy used by other hand-dryers or in terms of rethinking entire production, supply and retail lines to trim waste, as in the case of the world's largest retailer.

In addition to reducing costs, sustainable design is driven by a desire to reduce risk. While legislative risk is the primary element here -- especially for European manufacturers and Europe-facing retailers, with their REACH, WEEE, RoHS and other regulations -- there are also well known brand risks and risks to supplies of materials that could be impacted by environmental changes.

Coulter offered a number of tips on how to go about designing for sustainability, and more importantly, building sustainability into the design process early and often.

The first step is to estimate where the biggest impacts are for each product -- is it manufacturing, transportation, use or end-of life? -- so that designers can focus their efforts where smaller amounts of work will have bigger impacts.

Once you've got that map of where a product's impacts lie, then you can craft the "objective" of the eco-design. The chart below lays out how a sustainable-minded design process can cut impacts from any phase of life.

It is critical, Coulter said, to focus on sustainability early in the design process, since that's where the biggest impacts can be felt.

David Dornfeld, the department Chair and Professor of Mechanical Engineering at UC Berkeley and one of the presenters on yesterday's webcast, backed him up on that point by saying that he sees rapid growth in interest in sustainable manufacturing and sustainable design among his graduate and undergraduate students.
