The people who make everyday items – from cars to chairs to cell phones – attractive and functional are called industrial designers. Now a new generation of industrial designers is learning how to create products that are environmentally friendly as well. That makes their jobs a bit more challenging. Ann Dornfeld reports:


A lot of the things you buy have a pretty limited life cycle. Think about it. Before you buy a product, it uses up raw materials, then you use it for a while, then it ends up in a garbage dump. But that doesn’t have to be its fate.


A group of industrial design students at Western Washington University was given this challenge: create attractive, useful products that are also completely recyclable, reusable or biodegradable. On top of that, they had to use waste that would have ended up in the dump.


Rachel Bjarnasson explains what’s known as “closed-loop” design:


“Instead of a product life cycle and a designer’s job ending with that product when the product is at the end of its useful life, that that is just a new material that can be reused and turned into a new product.”


This sustainable design principle has caught on in Europe. There, household appliance manufacturers are required to take back old dishwashers and clothes dryers to reuse their components. U.S. factories are adopting closed-loop systems, too, as a way to save money on raw materials and benefit the environment.


One of the first lessons the students learned was that in closed-loop design, it’s not enough to use recyclable materials. You have to think about how you attach one material to another.


“If you have a recyclable material like an aluminum bonded to a plastic that’s non-recyclable, suddenly the recyclable component is no longer recyclable.”


Bjarnasson says they had to avoid using strong glues for that reason. And also because the adhesives can release toxic fumes.


The students also had to figure out where to get their raw materials.


Seth Tucker wanted to make bracelets out of disposable chopsticks.


“I found that between Japan and China, one billion pairs of chopsticks are thrown away every year. They’re taking down whole forests just for chopsticks!”


He asked local Asian restaurants whether he could install chopsticks recycling bins to collect enough for his project.


“Some restaurants, it was kinda funny, they gave me this kinda look like ‘you’re crazy, I would never give you used chopsticks.’ But it was really cool, ’cause other places were like, ‘oh yeah, totally, we’re definitely cool with the idea.'”


Tucker sanitized the chopsticks he’d collected, cut them into pieces and sandblasted them into what look like little driftwood beads. He strung them into bracelets along with natural turquoise and antique African trade beads.


One student turned newsprint into biodegradable flower pots.


Another made used-up retail gift cards into colorful luggage tags.


Rachel Bjarnasson challenged herself to use fabric scraps that she usually throws away in her job as a seamstress. She stitched strips of silk into baby booties, and lined them with scraps of fleece she got from a local glove manufacturer. Then she cushioned the soles with leftover carpet padding from a flooring company.


“And so all of this was materials that would’ve been thrown out, and I turned them into little striped baby booties.”


Several stores agreed to carry the products. One of them was Goods for the Planet in Seattle. Suzanne O’Shea is the co-owner.


“We were thrilled to do it because one of our goals is to find products as close to home as possible and support the local economy.”


The students’ products were a hit with her customers. O’Shea says some even sold out right away – like the chopsticks bracelets.


And sushi rollers made from stainless steel bicycle spokes flew off the shelves.


“And a lot of chefs that have come in and people that make sushi at home have really been impressed by this design because it has more weight than the standard bamboo sushi rollers.”


And that’s the idea. Student Rachel Bjarnasson says they learned the ideal sustainable product is at least as attractive and useful as the competition.


“You still need to make a product that looks beautiful and has good tactile sensation and is something that people ultimately want to buy. Even if it has the best of intentions in saving the environment, it won’t do its job if it’s not something that people want or need.”


The students say they’ll try to integrate the closed-loop design principles they’ve learned into all of their future products. They don’t want anything they design to ever end up in the trash.

Lessons From Green Building Design

Principles of sustainable design, or “green building” have been around for years. These are designs that, among other things, reduce energy use and create more comfortable working environments. Yet they are often dismissed as costly, impractical, and experimental. But green design has come a long way in recent years. The construction cost of an environmentally-friendly office building today is comparable with the cost of more traditional methods, and the maintenance costs are often much lower. Architects and builders across Pennsylvania have learned that, and the result has been a major shift in how buildings are constructed. And the lessons learned there could eventually make their way across the entire Great Lakes region. The Great Lakes Radio Consortium’s Brad Linder reports:

Principles of sustainable design, or “green building” have been around for years. These are designs that, among other things, reduce energy use and create more comfortable working environments. Yet they are often dismissed as costly, impractical, and experimental. But green design has come a long way in recent years. The construction cost of an environmentally friendly office building today is comparable with the cost of more traditional methods, and the maintenance costs are often much lower. Architects and builders across Pennsylvania have learned that, and the result has been a major shift in how buildings are constructed. And the lessons learned there could eventually make their way across the entire Great Lakes region. The Great Lakes Radio Consortium’s Brad Linder reports:

The Heinz National Wildlife Refuge at Tinicum Marsh lies just around the corner from the Philadelphia International Airport. The refuge is also home to the Cusano Environmental Education Center, celebrating its first anniversary as what many consider to be the city’s greenest building.

The Center’s heating and cooling relies on a geothermal system. About five hundred feet below the Cusano Center, the temperature remains near 50 degrees all year round. Deep wells reach into the ground to borrow heat in the winter, and cool air in the summer.

The Center also makes use of a “marsh machine,” to clean and recycle wastewater. Refuge Manager Dick Nugent says the machine uses natural processes to filter water through a “constructed wetland” of PVC pipes, gravel, and marsh plants. Nugent says the city water department delivers drinking water, but the marsh machine has a more important use.

“We wanted this here as an environmental education tool. It isn’t as if we needed it for the functionality of this building. The message to take home is that marshes serve a very important function.”

Cyrus Baym is a volunteer coordinator at the Cusano Center. He says people come expecting to learn about nature, but wind up getting something special out of the building.

“The people that are coming in, they see this fabulous building, a lot of space, a lot of glass, and then when you start explaining along with the exhibits the sustainable design features, the use of recycled materials, passive solar windows their eyes get even bigger. They get more excited and want to implement it in their own house.”

Refuge Manager Dick Nugent says there was some additional cost to innovations like the geothermal system and the southern wall of the building, which is made mostly of glass windows. But in the long run, many of those additions will wind up saving money on electricity and heating. And the overall goal isn’t to be frugal, but to teach.

On the other side of the state, another approach toward sustainable design is taking hold.

Pittsburgh is currently home to one-quarter of the nation’s buildings that have been certified as green by the U.S. Green Building Council. The non-profit national industry group represents design, construction, and environmental interests. The council also administers the Leadership in Energy and Environmental Design, or LEED, rating system, which judges the overall environmental performance of buildings.

Unlike the Cusano Center in Philadelphia, many of Pittsburgh’s green buildings weren’t designed to be educational tools. The PNC Firstside Center in Downtown Pittsburgh provides workspace for 1800 employees in the bank’s technology and processing divisions.

Elmer Burger was one of the principle architects for the building. He says designing the largest LEED certified building in the country made sense for the project. The large floor space improved communication within business departments, and also allowed for extensive use of natural light.

“With a large floor plate, we had an opportunity to make the ceilings higher and bring daylight further into the building. So you can be as far as 125 feet away from the outside wall and still have daylight in a view.”

Burger says the building’s large windows give employees a view of the Monongahela River, and also save money by reducing the need for artificial light.

Rebecca Flora is director of Pittsburgh’s Green Building Alliance, a non-profit group working to encourage and facilitate environmentally friendly design in the city. She says some non-profit groups are interested in green buildings for ideological reasons, but also wind up getting long-term economic benefits.

“The life cycle value of doing a green building is actually quite significant in some cases. I know with Conservation Consultants, their building actually uses 60% less energy than a traditional building, which can have huge implications in terms of the small operating budgets that many non-profits have to work with.”

Flora says saving money is one of the main factors in getting major institutions like PNC to build green

“The myth that is out there is that green buildings cost more, and that’s one that we’re constantly trying to educate people around in that you get what you pay for. We’re trying to educate people around the fact that green building also adds value, and how do we equate that value with increased bottom line is a real key issue for most people.”

Flora says it’s important to convince clients, and not just architects of the benefits of green design. She says if the demand for LEED certified buildings increases, sustainable design techniques will become more common.

A number of other commercial and non-profit institutions in the city have also chosen green design. Both the Alcoa Corporate Center, and the Greater Pittsburgh Community Food Bank are green buildings. And the new David L. Lawrence Convention Center is the first convention center in the country to earn LEED certification

With so many high profile green projects, sustainable design is starting to look like common sense to many architects and their clients. Elmer Burger says the success of the PNC Firstside Center has led the company to adopt a new policy. All of their new corporate buildings will be designed to meet LEED requirements.
