Newer Technology. Com.post.ability. Self Sufficiency. New adhesive system makes a circuit board that is 90% recyclable | Guardian Sustainable Business | Guardian Professional. Three British companies have developed a 90% recyclable and reusable circuit board, whose components can be easily separated by soaking in hot water. Funded by the UK government's Technology Strategy Board with a view to help industry conform to European electronic waste regulation, the National Physical Laboratory (NPL), In2Tec and Gwent Electronic Materials have devised an adhesive that helps manufacturers take apart electronic circuit boards and reuse their components to make new components.
They call it ReUse – Reusable, Unzippable, Sustainable Electronics. "What happens to end of life electronics is one of the fastest growing waste streams," says Chris Hunt, head of the Electronics Interconnection Team at NPL. "Existing electronic circuit assemblies are based on reinforced epoxy glass systems and solder. A circuit board itself is a significant part of a final product but it's made with a thermoset of glass that isn't easily recyclable. The design hub is funded by Nike. Biodegradable Plastic Option From Shrimp Shells. From the depths of the oceans to stomachs of whales waste plastics are out of control. Now there is a new entry in the quest for an alternative that won't require us to get more responsible about littering, although vegetarians may have very mixed feelings. Plastic waste is a classic tragedy of the commons problem. Even if we were able to get 90% of the people who currently dump products without thinking to mend their ways, the rest would still end up destroying marine life the rest of us love, just a little more slowly.
Twenty years ago there were hopes that starch or cellulose-based plastics would solve the problem. Since bacteria have had hundreds of millions of years to work out how to break these down they've got pretty good at it. But the products on the market have proven less than ideal. Some don't break down properly or do so only under certain circumstances, and they can cause problems for recyclers. Photo Gallery.
Macro Eco Solutions. O Eco Solutions. Panarchy. Panarchy What is Panarchy? Panarchy is a conceptual framework to account for the dual, and seemingly contradictory, characteristics of all complex systems – stability and change. It is the study of how economic growth and human development depend on ecosystems and institutions, and how they interact. It is an integrative framework, bringing together ecological, economic and social models of change and stability, to account for the complex interactions among both these different areas, and different scale levels (see Scale Levels). Panarchy’s focus is on management of regional ecosystems, defined in terms of catchments, but it deals with the impact of lower, smaller, faster changing scale levels, as well as the larger, slower supra-regional and global levels.
The development of the panarchy framework evolved out of experiences where “expert” attempts to manage regional ecosystems often resulted in considerable degradation of those ecosystems (Gunderson and Holling, 2002).

Seeds of a revolution Two years ago, Bhausaheb Thorat launched a campaign to turn a drought-stricken region into a lush forest. Huned Contractor traces his journey Every year since June 2006, 45 million seeds and saplings are planted in Sangamner tehsil (a group of villages), 200 km from Mumbai, to transform arid zones into green carpets. Behind the geographical metamorphosis lies the zeal of 84 year-old conservationist Bhausaheb Santuji Thorat. Thorat’s Dandakaranya Movement, which promises a thick wood cover in the years to come, was recently credited by the United Nations Environment Programme, with its website uploading a feature on Thorat’s initiative (www.unep.org /billiontreecampaign/CampaignNews/Dandakaranya.asp) as an example of how determination can work magic in the face of odds.
His story is also the subject of a Marathi book — Aadhunik Dandakaranyachi Kathaa (Ameya Prakashan; 2008) — by journalist Aruna Antarkar, who has travelled extensively with Thorat. Jean Giono - L'homme qui plantait des arbres. La nouvelle de Jean Giono qui suit a été écrite vers 1953 et n'est que peu connue en France. Par contre, traduite en treize langues, elle a été largement diffusée dans le monde entier et si appréciée que de nombreuses questions ont été posées sur la personnalité d'Elzéard Bouffier et sur la forêt de Vergons, ce qui a permis de retrouver le texte. Si l'homme qui plantait des chênes est le produit de l'imagination de l'auteur, il y a eu effectivement dans cette région un énorme effort de reboisement surtout depuis 1880. Cent mille hectares ont été reboisés avant la première guerre mondiale, surtout en pin noir d'Autriche et en mélèze d'Europe, ce sont aujourd'hui de belles forêts qui ont effectivement transformé le paysage et le régime des eaux.
Voici d'ailleurs le texte de la lettre que Giono écrivit au Conservateur des Eaux et Forêts de Digne, Monsieur Valdeyron, en 1957, au sujet de cette nouvelle : Cet homme parlait peu. Après le repas de midi, il recommença à trier sa semence. Meghalaya villagers create 'living' bridges by training roots across a river. By Daily Mail Reporter Updated: 15:35 GMT, 10 September 2011 Deep in the rainforests of the Indian state of Meghalaya, bridges are not built, they’re grown.
Ancient vines and roots of trees stretch horizontally across rivers and streams, creating a solid latticework structure strong enough to be used as a bridge. Ancient solution: The 'double decker' living tree root bridge in the village of Nongriat in Meghalaya, India. Locals have been using the bridges for over 500 years Some of the bridges are over a hundred feet long and can support the weight of fifty or more people. The Cherrapunji region is one of the wettest places in the world with many fast-flowing rivers and streams, making these bridges invaluable to those who live in the region.
Nature's incredible engineering: Some of the bridges can hold more than 50 people at a time. Interwoven: A close up of the solid lattice work that makes the bridges so strong. In time, a sturdy living bridge is produced. 12 Sustainable Design Ideas from Nature. “In this inspiring talk about recent developments in biomimicry, Janine Benyus provides heartening examples of ways in which nature is already influencing the products and systems we build.” -TEDx “Learning about the natural world is one thing, learning from the natural world is another.” - Janine Benyus There are 2 things that we need to ask ourselves in order to learn from the world around us. #1 How does nature make things?
When we make things we heat up materials and shape them into the products we use today. This has a 96% waste output and only 4% product output. With this in mind perhaps we are the ones that are not as technologically advanced as the world around us. Life makes everything by adding information or structure onto matter in order to give it function. #2 How does life make ‘things’ disappear into structure? 12 Sustainable Design Ideas from Nature 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12.

Urban Green Council report: How New York City could cut emissions by 90 percent by 2050. Photo by Mario Tama/Getty Images Climate scientists have estimated that, in order to avoid runaway global warming, the world would need to cut its carbon emissions roughly in half by 2050.
Since emissions in developing countries like China and India are still rising fast, meeting this target would require developed nations to aim for a figure more like 80 percent. When you consider that the United States, the largest polluter in the developed world, has no real strategy in place to achieve that—and that no binding international agreements appear to be on the horizon—the goal can start to sound nigh impossible. The task is so intimidating that even serious people are starting to entertain extreme-sounding geoengineering ideas like flying business jets into the stratosphere and spraying sulfuric acid all over the place to try to deflect sunlight before it reaches the Earth.
To get those emissions under control will require three main steps, all difficult but none inconceivable. Www.planetshifter.com | Come Together. TreeHugger. iFixit/CC BY-ND 3.0People are talking a lot about cell phone unlocking in the news this week. Until recently, unlocking mostly flew under the radar—a common technique used by consumers who need to use their phones with more than one carrier. But late last year the Librarian of Congress banned the practice, catapulting cell phone unlocking into the national spotlight.
Unlocking is a software tweak that disables a device’s SIM lock. So, once the contract is over, owners of unlocked devices can switch to the carrier of their choice. Carriers including AT&T and Verizon argue that unlocking a cell phone without permission is a violation of copyright under the 1998 Digital Millenium Copyright Act—a law originally designed to prevent piracy. For the past three years, cell phone unlocking has been exempted from the DMCA. Immediately after the ban took effect on January 26, the internet lit up in protest. On Monday, the fervor prompted a White House response. Cell phones and the environment. World Changing Ideas: 20 Ways to Build a Cleaner, Healthier, Smarter World. What would happen if solar panels were free?
What if it were possible to know everything about the world—not the Internet, but the living, physical world—in real time? What if doctors could forecast a disease years before it strikes? This is the promise of the World Changing Idea: a vision so simple yet so ambitious that its full impact is impossible to predict. Scientific American’s editorial and advisory boards have chosen projects in five general categories—Energy, Transportation, Environment, Electronics and Robotics, and Health and Medicine—that highlight the power of science and technology to improve the world.

Growing Power. How to Make The Most of Your Yard (Including Weeds!), Permaculture Style. Not all the world hates weeds. Sure, there are many gardeners scuffling around in the clogs, cursing those pesky dandelions (actually a highly medicinal plant) and that crabgrass blemishing their flower beds. They offer theories as to how to prevent them, when to get rid of them and, at the weakest and worst moments, may even spray a little agent orange, aka Roundup, to kill them dead, dead, dead.
However, it doesn’t have to be this way. In fact, with a little effort and a good plan, weeds and gardeners can live in harmony. In fact, it’s not just weeds. It’s all those twigs and sticks that loiter round beneath trees. That’s right. Step 1: More Garden, Less Grass The first and most exciting step of making your yard work for you is getting rid of the grass and making a garden (Here are ten reasons to do it!). The ultimate goal for maximizing your yard would be to have every square foot of it that isn’t a path be a garden bed. Step 2: Weed With a Purpose Step 4: Learn the Lay of the Land. Fix the planet. The problem with e-waste ¶ What is e-waste? ¶ Many people don't know that electronics have all kinds of nasty chemicals in them. For example, the glass in a typical CRT has about ten pounds of lead in it. Most flat panel displays contain significant amounts of mercury.
What happens to e-waste? To recycle electronics properly, you must carefully disassemble them and separate out each type of material. Why? From UNEP/GRID-Arendal Maps and Graphics Library But labor is cheap in the developing world. The United Nations Environmental program explains this process: "In many countries entire communities, including children, earn their livelihoods by scavenging metals, glass and plastic from old computers. How you can save the planet ¶ Use devices as long as possible ¶ Maintaining and repairing devices dramatically improves their usable lifespan. You have a responsibility to humanity to keep things working as long as possible and to dispose of them properly. Join the crusade ¶ Dry San Diego to look to sewers as water source. SAN DIEGO (AP) — Acknowledging California's parched new reality, the city of San Diego has embraced a once-toxic idea: turning sewer water into drinking water.
The City Council voted unanimously Tuesday to advance a $2.5-billion plan to recycle wastewater, the latest example of how California cities are looking for new supplies amid a severe drought. Each of the nine council members effusively praised the effort before the vote as a way to make San Diego less dependent on imported water and insulated from drought. "We're at the end of the pipeline," said Councilman Scott Sherman. "We have a real problem getting water down here. " Such recycling, called toilet-to-tap by critics, has suffered an image problem that industry insiders call "the yuck factor.
" San Diego, a city of 1.4 million people that imports 85 percent of its water from the Colorado River and Northern California, has slowly warmed to the idea. Still, it remains rare to turn sewage to drinking water. Review of solutions to global warming, air pollution, and energy security. Our Technical Reality. Eco Ontology. Humane Ecology. Recycle Reuse.
