Bokashi is a centuries-old Japanese method of recycling household food waste into all-natural compost.  By employing a special culture of yeast and other microorganisms, bokashi is a compact, odorless process that takes only days instead of weeks or months. Now the Bokashicycle company is breaking the process out of the kitchen and into a commercial-scale food waste recycling operation, in partnership with New Earth Farm in Hillsboro, Oregon.

New Earth Farm takes in food scraps from Bon Appetit cafeterias on the nearby Intel Hawthorn Farm campus, which provides a significant waste disposal savings compared to disposing the scraps in landfills.  Waste reduction is one goal, and in an even more sustainable twist the composted soil is used to grow crops for Abundant Harvest, a local consumer-supported agriculture (CSA) store.

Some of the landfill gas at McCarty Road Landfill in Texas was captured for sale to a local utility, but the rest was just getting flared. Now, though, Ameresco Services captures that excess and sends it four miles through an underground pipeline to Anheuser-Busch brewery to meet their goal of getting 15 percent of their needs by 2010 promised a few years ago.

How much business is there to be made in capturing and using waste energy? Well, the company that developed the energy recycling waste-to-power system that helps fuel the biopower plant at the brewery has got to be one of the few companies in this economy to enjoy 47% growth over the last 5 years!

A team of researchers at MIT are engineering a strain of bacteria, which is similar to the type that causes tuberculosis, to produce biofuel.

The researchers say that the bacteria are useful because they are hungry for a number of sugars and toxic compounds and produce lipids that can be converted to biodiesel.

Waste uranium can apparently be recovered very cheaply from the polluted runoff from uranium mining using E. Coli and a phosphate storage molecule found in seeds, British researchers have found. They used the common bacteria with a chemical parallel of what is already found in agricultural waste: inositol phosphate.

Inositol phosphate is insoluble, so it forms a precipitate on the bacteria. The E. Coli then broke down the precipitate; releasing the phosphate molecules which then attached to uranium molecules to form uranium phosphate, which can then be harvested to recover the uranium.

What they have developed is a way for one contaminant to clean up another.

Magnum D’Or Resources Inc., a rubber recycling company, now owns one of the world’s largest tire landfills in Hudson, Colorado. But they’re not going to just leave it there. Old tires are bad because they breed mosquitoes, and a tire fire will burn for months. Read the rest of this entry »

2k Manufacturing based in Luton, England has come up with a process that can take any type of plastic - clean, dirty, or defected - and remake it into what they’re calling ‘EcoSheets’.  These EcoSheets are a composite material made to have the same mechanical properties as plywood.  They are the end result of a process called powder impression molding, which takes all forms of plastic and makes it into a fine powder.  The powder is then sandwiched in between two polymer films and is heat treated to form a viable substitute for plywood, a ubiquitous building material.

We live in an era where compute capability is ubiquitous, whether it be on a smart phone or mobile computer, and where “the cloud” can be accessed from anywhere.

In parallel, the ever-improving energy and carbon-efficiency of computers creates new opportunities to trade off atoms for bits, also known as de-materialization, and to substitute carbon-intensive activities, such as transportation, with tele-presence.

Here in Intel’s Eco-Technology group, we’re trying to learn precisely where these trade-offs exist, and under what conditions society can achieve net-positive outcomes, by harnessing technology in more environmentally beneficial ways. To that end, together with Microsoft’s sustainability group, we asked Dr. Jonathan Koomey, visiting professor at Yale’s School of Forestry and Environmental Studies and an expert in energy conservation technology, economics, policy and global climate change, to undertake a study of the environmental tradeoffs, between purchasing music in the traditional fashion (on CD from an online or brick and mortar store), versus purchasing and downloading the digital files.

The U.S position on Climate Change is overshadowing all other discussions in the lead up to Copenhagen, even at a conference I recently attended in Melbourne Australia - the 5th Australia-New Zealand Climate Change & Business Conference, August 24-26th. The Australian position requires global consensus for a greenhouse gas emissions target by 25% with a successful Post 2012 Agreement in place, but only 5% if that is not concluded. It all depends on what the U.S does in Copenhagen according to their minister Penny Wong.

The European Union is the only group that will continue with strong commitments independent of the U.S position with a 20% reduction of greenhouse gases on 1990 levels by 2020 and 30% if a global agreement is concluded.

Editor’s Note: Carrotmob is a form of consumer activism that invites businesses to compete in order to win a mob of customers. But everyone wins, because the extra money the winner makes goes toward things like improving their energy efficiency. Usually the business who promises the largest percentage of revenue from the event wins, but this Carrotmob was done a little differently. Each contestant explained what they’d do if they won, and what they were currently doing around sustainability, and the general public voted, actually choosing the one who had already shown the greatest commitment to sustainability. Epicenter wanted to get some feedback from the public around what type of to-go containers to use.

What is the most sustainable type of take-out packaging?

Ah yes, the burning question that keeps many an environmentalist tossing and turning well into the night. On the one hand, PLA, aka “polylactic acid” comes from plants, not petroleum, so it must be good, right? But which plants does it come from? And what part of the plant? Is it waste being upcycled? Is it replacing food crops? It must be good, right, it’s not petroleum!?

Epicenter Café, being a very conscientious Carrotmob winner, wants to be sure they make the right choice. They also want your input, sage readers. So I present to you the options, because even the Green Café Network does not take an official stance on this ever-evolving topic. There is an increasing array of options for eco to-go containers.

The U.S. Virgin Islands have a five times greater energy consumption per capita than the U.S. mainland. Oil fired generators provide the islands electricity.  But it also has a great resource for renewable energy.

Two million of us feasting tourists a year leave a lot of leftovers. So much so, actually, that the territory has faced EPA fines for excess solid waste and has almost run out of places to put the 146,000 tons of garbage we leave behind every year.

The Recovery Act offers $8 million for renewable projects in the Virgin Islands, which has no renewable power as yet, despite abundant solar and wind potential. But the energy potential of all those leftovers might be even greater. And here’s a company that wants to use it:
