When green jewelry designer Kathleen Nowak Tucci of My Sister’s Art contacted us with the news that her recycled rubber jewelry made the cover of Vogue Italia I was thrilled; I’d seen her dramatic necklaces featured in Ecouterre and I am always happy when green fashion designers are recognized by mainstream fashion press. However, upon closer examination at the “Water & Oil” ed… Read the full story on TreeHugger

NSF Awards $510K to NDSU and Clarkson Researchers to Explore Use of Nanostructured Enzyme Capsules for Hydrolysis of Biomass for Fuels

The National Science Foundation (NSF) has awarded $510,335 to a collaboration between North Dakota State University and Clarkson University researchers professors for a research project to improve conversion and reduce costs of making fuels from cellulosic biomass.

The goal of the project—“pH-Responsive Capsules for Enhanced Delivery and Recovery of Cellulases for Biomass Hydrolysis”—is to enhance conversion of cellulosic biomass into fermentable glucose to convert into ethanol or other chemicals or fuels. Their work aims at improving efficacy and reducing costs of cellulase enzymes needed for converting biomass to soluble sugars.

Andriy Voronov, NDSU assistant professor in the Department of Coatings and Polymeric Materials, and Scott Pryor, assistant professor in the Department of Agricultural and Biosystems Engineering, will receive $309,357. Sergiy Minko, chaired professor of chemistry at Clarkson University, Potsdam, N.Y., was awarded $200,978.

Enzymatic hydrolysis of plant cell wall structural carbohydrates into soluble and fermentable sugars has been technically achievable for decades. Despite significant advances in the past five years, the economical production and use of cellulase enzymes for biomass hydrolysis remain key hurdles, whether the targeted end product is hydrocarbons or economical cellulosic ethanol.

The key to conquering these obstacles according to the collaborating PIs Voronov and Pryor rests in placing the enzymes in nanostructured capsules. These hybrid organic-inorganic microcapsules are loaded with a cocktail of cellulase enzymes for the conversion of cellulose into fermentable glucose.

The capsules protect the enzymes and preserve their activity, allow for a simple reuse/recovery process for the enzymes, and provide an opportunity to regulate enzymatic reactions using external signals, such as pH. This enzyme recovery and reuse, facilitated through the encapsulation process and magnetic separation, are expected to have significant impacts on processing costs to produce biomass-derived sugars.

The PIs plan to create a website as a means of sharing data and plans between the research groups at the two universities, and to allow public access to follow aspects of the project.

Report: Honda to Aggressively Price New Fit Hybrid In Japan

Kyodo reports that Honda Motor Co. has decided to sell its new hybrid car for around ¥1.59 million (about US$18,600), which will be the lowest price for a gasoline-electric vehicle sold in Japan, according to company sources.

The price of Honda’s new Fit compact car to be released in October will be some 300,000 yen lower than the 1.89 million yen price tag for the cheapest model of its Insight hybrid put on sale in February last year.

The move is expected to accelerate competition in the development and sale of environmentally friendly vehicles between Honda and Toyota Motor Corp., which is expected to release a new compact hybrid next year that will do more than 40 kilometers per liter [94 mpg US, 2.5 L/100km] of gasoline and have a price tag of around 1.5 million yen, analysts said.

The new Fit will feature a 1.3-liter engine and electric motor, with fuel economy of 30 km per liter (70.6 mpg US, 3.3 L/100km).

$2.2M Project to Advance Bio-Oil As Basis for Renewable Chemicals, Fuels and Energy

Aston University’s (UK) Bioenergy Research Group (BERG) is involved in a £1.4-million (US$2.2 million), two-year project aimed at developing technology for producing and fractionating bio-oil components as a basis for a biorefinery producing green chemicals, transportation fuels and energy.

The Bio-oil Refinery Project is part funded by the Research Council of Norway (RENERGI) program, and will develop new, integrated bio-oil technology to transform biomass more efficiently into biofuels through fast pyrolysis.

Coordinated by the Paper and Fibre Institute (PFI) in Norway, The Bio-oil Refinery Project involves Aston University and several partners from Norway and Sweden.

Biomass liquefaction is done by fast pyrolysis, a pretreatment technology that is very flexible with respect to feedstock. Fast pyrolysis also brings efficient energy densification, which makes the technology suitable for decentralized bio-oil production of wood waste materials with favorable transport costs.

his project will serve to form an international network between industry, academia and research institutes. We need to develop more efficient technologies to not only make bio-oil viable on a large scale at lower costs, but also to derive transportation fuels with similar objectives.

—Tony Bridgwater, Professor of Chemical Engineering and Head of BERG at Aston University

BERG has coordinated 11 substantial EC sponsored RTD projects and is managing SUPERGEN, a UK University Consortium in thermal biomass conversion, PyNe, a biomass pyrolysis network, and ThermalNet, a new European network for biomass pyrolysis, gasification and combustion.

Roush Yates to Supply Ford EcoBoost V6 Engines for American Le Mans

Roush Yates, one of racing’s premier designers and constructors of high-performance engines, will become an engine supplier in American Le Mans’ LMP2 starting in 2011. Its initial offering is the Ford V6 EcoBoost Turbo for installation in a variety of prototype chassis.

Chassis constructor Lola has already announced that it will offer the Roush-prepared EcoBoost as a standard installation in its open-top and coupe prototypes.

This…is another example of a manufacturer that shares our view of racing’s relationship to the showroom—using a high-performance environment such as the American Le Mans Series to develop relevant, innovative technology that can be transferred to production cars. We continue to stand alone as motorsport’s leader in manufacturer diversity and innovation, two traits that we believe were critical to Roush Yates’ decision to supply Ford engines for LMP entrants starting next season. With today’s announcement we now add another major brand to the list of LMP engine suppliers for 2011—Honda having already announced and displayed its new LMP motor at Le Mans earlier this year. The addition of Roush Yates and its Ford engine now gives LMP entrants two excellent choices with more still to come.

—Scott Atherton, Series President and CEO

Roush Yates joins a number of committed engine suppliers for LMP competition in 2011, including Honda, along with longtime Series competitors AER and Judd. With next year’s LMP2 regulations specifically targeting production-based engines with reduced horsepower and increased efficiency, other manufacturers such as BMW, Ford, Jaguar, Nissan and Toyota have each been actively rumored as potential suppliers next season as well.

In addition to the V6 EcoBoost Turbo, Roush Yates also is evaluating its Mustang V8 for LMP competition. Both the engine constructor and Lola are investigating the potential for LMP1 cars in the future, perhaps as early as next year.

JRC Report Concludes Extreme Weather Wont Affect Average Levels of European Crop Output for 2010; Yields Up, Although Acreage Down; Heat and Drought Have Huge Impact on Russia

The European Commission says cereal production in 2010 will be close to the average recorded since 2005. According to a report drafted by the Joint Research Centre (JRC), the yield per hectare will be 5% above average, while cultivated areas will shrink on the whole.

Europe has faced a number of extreme weather events, such as floods and rain shortages, since the start of the year. In its report, the JRC notes that bumper harvests in some EU areas have helped counterbalance the effects of poor weather on crops in other areas. The report also says that even though the EU’s cereal harvest should reach average levels this year, extreme hot and dry conditions will have a huge impact on winter crop production in Russia.

Russia has already issued a ban on exports of wheat, corn, barley, rye and flour from 15 August through to the end of the year due to the wildfires that have devastated the country. Russia ranks fourth on the global list of wheat exporters.

Europe was hit by very low temperatures in December 2009, as well as in the first three months of 2010. The extreme cold kept farmers from starting their season on schedule. Meanwhile, both spring and early summer brought a severe shortage of rain to Belgium, the Czech Republic, northern Germany, Greece, France, Luxembourg, the Netherlands, eastern Poland and the UK. The Czech Republic, Hungary, Poland, Romania and Slovakia were hit by floods in the spring. Very high temperatures were recorded in Belgium, Germany, France, Luxembourg and the Netherlands in June and July coupled with low rainfall.

The JRC used an novel crop yield forecasting system to provide yield estimates for the main crops across the EU. Based on its findings, the yield forecast for cereals, including wheat, barley and maize, is 5.1 tonnes per hectare across the EU, up 0.7% year-on-year, and 5.0% higher than the five-year average.

Estimates show that the overall area used in the EU for cereals in 2010 shrank by 3% year-on-year. Since 2005, individual crop yield figures in general rose in the EU-27. For cereals, grain maize recorded the biggest jump (+7.7%), followed by barley (+4.4%), soft wheat (+1.7%) and durum wheat (0.3%). For other crops, sunflower increased 7.2%, representing the highest increase in the bunch, followed by potato (+6.9%) and sugar beet (+2.3%). Rape seed was down 2.4%.

The report also estimates that the yield for soft wheat will top the five-year average. However, two leading producers from Germany and France show below average yields that are also below the level recorded in 2009. It should be noted that the dry and hot conditions that surfaced there in recent weeks have also played havoc with the yields.

Spanish farmers will likely see their yields of durum wheat drop 16% below average thanks to the excessive rainfall that affected Andalucía during the winter, while their Italian counterparts, the major producers of durum wheat, will post a similar average yield to their French neighbors.

The report also notes that the dry and hot conditions did not make a huge impact on winter barley. Germany and France will likely report average levels compared to the five-year average, but a 4% drop on 2009 levels. Spain, which covers around 25% of the spring barley output, will probably have a yield that is 15% above the five-year average.

GM Will Re-Introduce “Mild Hybrids”


Remember a few years back, when all of the sudden the market was flooded with hybrids? I’m not talking about the Prius or the Insight, genuine hybrid cars, but rather the “half-hybrids” cranked out by GM and Chrysler prior to their bankruptcy proceedings. There was the Saturn Vue Green Line, Cadillac Escalade Hybrid, the Chrysler Aspen Hybrid, even the Chevy Silverado Hybrid. Rather than running on electric engines at low speeds, some of these systems (like those in the Vue) used stop-start technology to save fuel when at a stop sign. Kinda half-hearted if you ask me.

After canceling all their hybrids, GM is set to return with their “mild-hybrid” system sometime next year. So will it meet with more success than the first time around?

A university study on Lake Erie walleye may help scientists spot rivers that are at risk of overfishing. Researchers at Ohio State analyzed chemicals found in walleye ear bones, and were able to figure out which fish returned to their hatching site to spawn, and which ones went elsewhere, creating some rivers that are vulnerable to overfishing. The fish seem to be saying, “Can you hear me now?”… Read the full story on TreeHugger

Though it may seem like a no-brainer to some, incorporating and encouraging biodiversity-friendliness in newer sustainable buildings is a must. With major declines observed in bee, bat, bird and other critical species, it makes sense that newer built environments now being designed with zero- or low-carbon status in mind should also integrate ways to boost wildlife diversity as well.
