Water soluble circuit boards could revolutionize e-recycling (!)

Posted on November 7, 2012 – 07:00 by Beth Buczynski,EarthTechling

 Things labeled “just add water” are usually highly-processed foods and novelty bath tub toys, but new research from the UK’s National Physical Laboratory may change all of that.

Working together with In2Tec and Gwent Electronic Materials, NPS has developed a 3D printablecircuit board that dissolves when immersed in hot water.

The technology was created as part of the UK’s ReUSE (Reuseable, Unzippable, Sustainable Electronics) project which aims to increase the recyclability of electronic devices.

Although the circuit board is merely printed, it has been shown to withstand heat and other pressures of real life use. Yet, when the hypotheical device breaks down, disposing of the non-recyclable parts is as easy as adding water.

According to the NPL, researchers developed and tested a series of unzippable polymeric layers which, while withstanding prolonged thermal cycling and damp heat stressing, allow the assemblies to be easily separated at end-of-life into their constituent parts, after immersion in hot water. The project demonstrated a 90 percent recyclable inverter circuit for an electroluminescent lamp dissolving in a small amount of hot water.

While this application of 3D printing won’t make electronic devices more resilient or eaiser to repair, in fact, quite the contrary, it does bode well for the planet.

Electronics waste is the fastest growing waste stream in the world, and traditional recyclingmethodologies aren’t capable of keeping up. According to the NPL, the water-soluble technology lends itself readily to rigid, flexible and 3D structures, which will enable theelectronics industry to pursue new design philosophies – with the emphasis on using less materials and improving sustainability.

San Francisco hits 80 percent landfill diversion!

By Editorial Staff, Resource Recycling

San Francisco has set a new national recycling and composting record by achieving an 80 percent landfill diversion rate — the highest rate of any city in North America.

The City by the Bay now only sends 20 percent of its refuse to landfill as the result of aggressive effort by the city’s leadership along with its partnership with waste management company Recology to increase reuse, recycling and composting, as well as source reduction of waste.

“San Francisco is demonstrating once again that zero waste is an achievable and environmentally-responsible goal,” said David Chiu, board president of the San Francisco Board of Supervisors, in a prepared statement. “I thank Recology and the Department of Environment staff who are reaching out and educating our residents and businesses to make sure they continue to recycle and compost our way to zero waste.”

The milestone puts San Francisco closer to achieving its goal of sending nothing to landfills or incinerators by 2020.

Shaper’s All-Natural Boards Bring Sustainability Back to Surfing

  • By Blanca Myers

dannyhess_002Surfers are some of the most ardent environmentalists, yet their sport is awash in petrochemicals and carcinogens, from neoprene wetsuits and urethane leashes to polyurethane boards and epoxy. Danny Hess thinks there’s a better way, and he’s made bringing sustainability to surfing his life’s work.

The 37-year-old surfboard shaper is making waves in the $7 billion surfing industry with his adoption of salvaged wood, natural finishes and organic resins. Hess wants to transform how surfboards are made — and how they’re used. His boards are built to last, an anomaly in a sport where surfers might trash a board or two every season.

“What I’m trying to do is build heirloom surfboards that are passed on from father to son over many generations, rather than these disposable things that we’re just consuming,” Hess says. “The idea is that you just buy one and take care of it and hopefully you don’t have to come back and buy another surfboard.”

As a child, Hess possessed a keen interest in the outdoors and working with his hands. He was using beach trash to make bodysurfing handplanes and was shaping surfboards before he could even drive. Before founding Hess Surfboards, he lived in a straw-bale house in Colorado, studied sustainable architecture at the San Francisco Institute of Architecture, built tree houses and worked as a licensed contractor. But even as his remodeling business prospered, Hess felt frustrated and dissatisfied by his career. A dozen years ago, Hess found himself spending his spare time experimenting with surfboard technology to escape the creatively stifling world of zoning ordinances, building codes and government regulations.

His work as a contractor provided a solid foundation for his work as a surfboard shaper.

“One day I had this “aha” moment where I realized I could create these molds, like the ones I was using to bend wood for cabinet doors, for surfboards,” Hess says.

Wood surfboards are nothing new, of course. Boards have long been made of wood and natural oils, and some surfers have never ridden anything else. But polyurethane has been the standard for half a century, mostly because it is cheaper, lighter and easier to use than wood.

Polyurethane was originally developed as insulation for aircraft and refrigerators during World War II. Early pioneers like Bob Simmons, the father of the modern surfboard, began experimenting with foam in the late 1940s, and shapers like Whitey Harrison and Hobie Alter honed the process through the 1950s. By the early 1960s, polyurethane was the go-to material.

Surprisingly, the fundamental technology has changed little in the decades since, largely because Clark Foam dominated the field. At its height, the California company supplied more than 90 percent of U.S. market for the inexpensive foam slabs, called blanks, that shapers use to make surfboards.

But polyurethane is nasty stuff. It contains toluene diisocyanate (TDI), a cyanide-rich compound that, when heated, releases fumes that can cause asthma, cardiac arrest, respiratory failure, hearing and vision loss, and other problems. Increasing harassment from state and federal environmental regulators prompted Clark Foam — where, media reports later showed, there was one TDI-related death — tosuddenly close its doors on Dec. 5, 2005. It simply shut down without warning, an incident known asBlank Monday.

“There was just no foam one day,” Hess says.

Clark Foam’s closure prompted a discussion among surfers and shapers about the sustainability of their sport, a topic Hess was well-versed in. He started using natural materials in 2000, drawing ideas and inspiration drawn from luthiers, boatmakers and other artisans. Going green, he says, is good for surfing and for surfers.

“I think our bodies are more in tune with organic materials,” Hess says. “My boards feel more natural than foam boards. I get a lot of people saying my boards feel really different, but really familiar at the same time.”

Today, he hand crafts 150 boards each year using raw materials like reclaimed poplar, cork and blocks of recycled expanded polystyrene. The surfboards, which range in price from $1,295 to $1,800, take about 10 and 16 hours to build. Whereas conventional shapers carve a big slab of polyurethane, called a “blank”, down to the shape they want, Hess builds his boards from the interior. First, he crafts an interior skeleton for his boards using a system of vacuums, one of 20 molds, and autoclaves. Hess then fills the framework with the foam, covers it all with salvaged wood and seals it with a sap-derived epoxy.

“I’m building from the internal frame structure to the exoskeleton of wood,” Hess said. “I have a system of vacuum molds and forms, autoclaves, that I use to create a specific curve or shape for the wood.”

Most surfers are initially attracted to Hess’ surfboards because of their eye-catching design aesthetic, but they also offer more flex. “When you ride them you find they have a really unique springy responsiveness. The way the strength is built along the rails gives you an immediate responsiveness to flex. And they’re light,” said Luke Bartels, a longtime Hess Surfboard owner and furniture designer in San Francisco.

Each of Hess’ boards are constructed at Woodshop, a studio Hess shares with three shopmates not far from San Francisco’s Ocean Beach. Being so close to the ocean makes R&D a breeze, as the beach is but a quick skateboard ride away. That led Hess to his latest endeavor – making skateboard decks using scraps lying around the shop.

“These skateboards are made for cruising down to the beach to check the surf and getting a six pack on the way back,” Hess says with a laugh. His skateboards echo the experience of surfing.

“When you’re skating on these boards and you flex into a turn you spring out,” said Hess. “It really feels like you’re surfing.”

It’s all about the surfing for Hess, and bringing innovation to the sport. He isn’t embracing sustainability for sustainability’s sake, but because he believes natural materials are genuinely better.

“My whole motivation has been about moving the ball forward for what surfboards could be, rather than sitting on a technology for 50 years,” Hess explains. “I have an idea, I come into my shop, and I do it. I’m always learning.”

That attitude led Hess to embrace Super Sap, the first USDA BioPreferred Certified liquid epoxy resin. And he’s experimenting with organic foam and salvaged redwood in a continued quest to build a truly green surfboard.

“My ultimate goal has always been to build a surfboard from locally sourced salvaged wood that contains no petrochemicals,” Hess says. “I don’t think we’re too far off from it.”

We hope olympians won’t have to test the mettle of their medals by selling them as scrap metal

LONDON – The value of an Olympic medal, for many the crowning achievement of a lifetime’s work, is of course priceless – an irreplaceable memento to outstanding athletic achievement.

Yet in real terms, at least for the third place finishers at London 2012, the actual monetary value of medals is astonishingly low.

 The bronze medals awarded at these games have been valued at just £3 ($4.71).

[ Photos: U.S. medal winners ]

 

Those that occupy the bottom rung of the podium are given prizes that are made up of 97 percent copper, 2.5 percent zinc and 0.5 percent tin, which according to London’s Daily Mail newspaper makes them worth £3 at current prices.

“Copper is not a particularly valuable metal,” jewelry expert Dan Cohen said in a telephone interview with Yahoo! Sports. Cohen is director of Bellore, a leading store in Hatton Garden, the famous jewelry quarter of central London. “Copper prices have gone up recently though, so much so that people have been stealing brass cables and so on. One and two pence pieces in the United Kingdom are no longer made of copper, because they would be more valuable if they were melted down.”

London 2012 medals weigh just under one pound and at three inches across are the biggest ever awarded at a Summer Olympics. They were designed by artist David Watkins and 4,700 of them will be handed out over the course of the event.

The gold and silver medals, naturally, have a greater actual value. A gold is worth $644, yet is only one percent gold, with the rest made up of silver and copper. The silvers replace the gold element with extra copper, and are worth about half as much.

Such prices are effectively irrelevant though, as any Olympic medal that comes on the collectors market can command huge sums from memorabilia hoarders.

Ewok treehouse goes green

Posted on July 21, 2012 – 11:12 by Susan DeFreitas, EarthTechling

If you ever had a tree house as a kid, or saw The Return of the Jedi, or both, chances are, you’ve dreamed of a tree house village.

Erica and Mateo Hogan did, and in 2005 — with the help of some friends who shared that dream — they created Finca Bellavista, a tree house community nestled high in the canopy of the Costa Rican rainforest connected via ziplines.

Billed as the world’s first planned, modern, sustainable, and truly arboreal tree house community, this neighborhood (which comes to us via Inhabitat) is located in the south Pacific coastal region of Costa Rica.

Offering comfortable-yet-rustic private lodgings for those seeking a home (or a second home) in the trees, the neighborhood features a base camp with a dining hall, an open-air lounge (with Wifi, of course!), a rancho, a bath house, a campfire ring and a wedding garden.

Nearly half of the community’s SkyTrail transportation network is currently up and running, offering views of the forest canopy and Bellavista River, which runs through the property. Treehomes are now starting to speckle the skyline, along with a handful of cabinas and treehouses that are ready for rentals and tours.

The community offers eco-lodgings for the tourist craving a natural retreat from civilization — the closest town to the community  a school, a church, a pulperia, a bus stop, a handful of houses, and of course, a soccer field, but nothing else: no souvenir shops, no mini-malls, no billboards and no bars.

And for those who’d like to make that kind of peace and quiet a regular part of their lives, the community offers a limited number treetop “plots” where you, too, can building your dream treehome. (A number of these are currently under construction.)

In addition to maintaining sustainable practices throughout the community — including sourcing all of its food from within five miles, and growing much of it on site — Finca Bellavista fundsconservation programs centered on the southern zone of Costa Rica, where it’s located. 

It also works to assist communities throughout Latin America in regenerating rainforest assets and restoring native habitats to encourage healthier lifestyles, economies and opportunities. More information is available online.

12-Year-Old Starts Recycling Business, Donates Profits to Charity

Stephen Messenger Living / Culture June 4, 2012

NBC News/Screen capture

When Sam Klein was still in kindergarten, he became fascinated with the things we throw away. Every week, on trash-collection day, the curious youngster would wait outside his house in St. Louis to watch, talk with, and oftentimes assist the visiting garbage men as they made their daily rounds. It was then, perhaps, that Sam first learned of the ugly realities of landfills — which may be why the now 12-year-old entrepreneur has entered the national spotlight for his recycling business.

“When you throw something away … it hasn’t gone away,” says Sam. “It’s just gone to a different location.”

So, for the last few years, Sam has dedicated his free time visiting local businesses to collect their empty printer ink cartridges, an easily recyclable item too often destined for the local dump. Once he gathers enough, Sam sorts them and sends them back by the box-full to the manufacturers, who pay sometimes as much as $200 for the recycled materials.

While his bold plan has shown that recycling can be profitable for both the environment and business-owners, the preteen pioneer never intended to line his pockets. Sam has donated all proceeds from his recycling charity — around $1,000 so far!

“It hurts him to see someone tossed aside, whether it’s a person or it’s garbage,” says Sam’s mother, Rachel.

Earlier this week, Sam garnered some well-deserved national attention. The story of this recycling philanthropist’s remarkable work was featured on NBC Nightly News — inspiring countless others with Sam’s youthful wisdom and contribution to making the world a better, cleaner, place.

School kids urge Crayola to rethink recycling

 

A group of California grade school students wants Crayola to start a recycling program for spent plastic markers, but the company doesn’t appear ready to make such a move.

About 40 students at Sun Valley elementary school in San Rafael, Calif., have been promoting an online petition aimed at nudging Crayola, a subsidiary of Kansas City-based Hallmark, into developing a “take-back” program for used-up markers.

Principal Julie Harris said Wednesday that the student group has been meeting at lunchtime for a couple weeks to discuss the project and monitor the petition’s progress. The petition on Change.org had more than 60,000 signatures by Saturday.

The students plan to present the petition to Crayola, Harris said.

“I don’t think they thought they were going to get there so quickly,” she said. “They were hoping the Crayola company would take notice of it.”

Crayola has, but spokeswoman Stacy Gabrielle said in an email that while the crayon maker encourages “children to share their ideas,” the company has no plans to offer a recycling program for its markers.

She said Crayola does not have “the facilities or a process” for a recycling program, but that the markers’ caps can be recycled at facilities that take that type of plastic. She also said because of the contents of the markers, the company doesn’t recommend recycling them.

“Because only the marker plastic is recyclable, not the ink reservoir or the tip, we do not recommend that consumers recycle the markers themselves,” she said. “It would require the removal of the nib and reservoir which could create small parts, a choking hazard to small children.”

Crayola is, however, “very committed to doing our part to take care of the environment,” Gabrielle said. She said Crayola uses solar energy to manufacture about 1 billion of the 3 billion crayons it makes each year and its markers are made with recycled plastic.

Land Wilson, the Sun Valley school parent who helped the students with the petition, said Thursday he’s not discouraged by the company’s response and hopes the company will reconsider.

“We’re moving forward,” Wilson said. “We love Crayola. This is all a very positive thing. … (The kids) want to keep using their products, but they want to be green.”

Wasted Food No More


Massachusetts may ban big institutions from discarding food in the trash in a bid to cut down on the methane from landfills. David Biello reports
| Sunday, May 13, 2012 | 4

When you don’t clean your plate, microbes feast. And Americans are awfully good at feeding microbes, wasting some 222 million metric tons of food a year. That’s a quarter of our food.
Much of that wasted food ends up in garbage dumps, turned by microbes into methane, a powerful greenhouse gas and one of the primary culprits behind global warming.
Now government officials in Massachusetts would like to ensure that restaurants, universities, hospitals and other large institutions don’t exacerbate that problem. The idea is to make sure all that wasted food doesn’t end up in landfills but instead becomes either compost or energy.
The same microbes that turn food into methane in a landfill can turn food into methane in a biodigester and that methane can then be used as a fuel. More importantly, from the Bay State’s perspective, it will keep the state’s landfills from filling up.
Of course, the methane from landfills can also be harvested, and often is. And, as the Pilgrims knew, it would be even smarter not to waste the food in the first place. But let’s give thanks for another helping of new ways to curb climate change.

Californians recycled over 16 billion beverage containers in 2011

By Editorial Staff, Resource Recycling

California’s beverage container recycling rate stayed essentially flat last year, but still reached gaudy heights according to a recently-released report by the state’s Department of Resources Recycling and Recovery (CalRecycle).

According to CalRecycle’s Biannual Report of Beverage Container Sales, Returns, Redemption, and Recycling Rates the Golden State recovered 16.7 billionbeverage containers in 2011, for an overall, program-wide recycling rate of 82 percent.

In order of reported rates from CalRecycle, the recycling rate for HDPE was 104 percent, aluminum was 97 percent, glass was 84 percent, 67 percent for PET, 16 percent for bi-metal containers and 15 percent or less for LDPE, PVC, PP, PS and other materials.

Resource Recycling reached out to several officials at CalRecycle for comment on the methodology used to calculate these numbers, but did not receive responses by press time.

“The California program is the largest beverage container recycling program in North America, recovering approximately one-fifth of all the beverage containers recycled in the U.S., annually,” said Susan Collins, executive director of the Container Recycling Institute, to Resource Recycling. “In addition, this program recovers containers that are worth over $300 million in scrap value each year, which is a valuable economic boost for the Golden State.”

Collins also noted that a less well-known fact about the program is that scrap values of aluminum and PET — which account for 83 percent of the containers in the program — are lower than the state-audited “cost to recycle,” meaning that beverage manufacturers pay zero processing fees for these materials.

“Another little-known fact is that California curbside programs receive payments of over $100 million per year for collecting beverage containers,” Collins said. “This is the largest program in the U.S. to financially support municipal curbside programs without payments by taxpayers or rate payers.”

Carbon Fiber Recycling program picking up steam

Trek Bicycle has announced that it has recycled over 700,000 pounds of carbon fiber, a material used to make high-end bikes, as well as other purposes, since launching a pilot program last year.

The Waterloo, Wisconsin-based bicycle manufacturer launched the pilot program seeking to collect scrap carbon fiber used in its bike frames for recycling. The lightweight and strong material is used by the aerospace industry as well as by bicycle manufacturers. It was previously thought to be unrecyclable, and the initiative by Trek was one of the first forays into recycling the material. Bike maker Specialized also launched a similar initiative last year.

As part of the project, Trek worked with Materials Innovation Technologies LLC and its subsidiary MIT-RCF, which processed the material at its South Carolina facility. Since last year, Trek has sent all of its carbon fiber manufacturing scraps, non-compliant components and reclaimed frames to MIT for repurposing in reinforced thermoplastic applications, such as aerospace, automotive, medical and recreational purposes.
