    Kazakhstan will next year adopt laws to regulate its fledgling biofuel industry and plans to construct at least two more plants in the next 18 months to produce environmentally friendly fuel from crops, industry officials said. According to Akylbek Kurishbayev, vice-minister for agriculture, he Central Asian country has the potential to produce 300,000 tons a year of biodiesel and export half. Kazakhstan could also produce up to 1 billion liters of bioethanol, he said. "The potential is huge. If we use this potential wisely, we can become one of the world's top five producers of biofuels," Beisen Donenov, executive director of the Kazakhstan Biofuels Association, said on the sidelines of a grains forum.

    SRI Consulting released a report on chemicals from biomass. The analysis highlights six major contributing sources of green and renewable chemicals: increasing production of biofuels will yield increasing amounts of biofuels by-products; partial decomposition of certain biomass fractions can yield organic chemicals or feedstocks for the manufacture of various chemicals; forestry has been and will continue to be a source of pine chemicals; evolving fermentation technology and new substrates will also produce an increasing number of chemicals.

    Analysts think Vancouver-based Ballard Power Systems, which pumped hundreds of millions and decades of research into developing hydrogen fuel cells for cars, is going to sell its automotive division. Experts describe the development as "the death of the hydrogen highway". The problems with H2 fuel cell cars are manifold: hydrogen is a mere energy carrier and its production requires a primary energy input; production is expensive, as would be storage and distribution; finally, scaling fuel cells and storage tanks down to fit in cars remains a huge challenge. Meanwhile, critics have said that the primary energy for hydrogen can better be used for electricity and electric vehicles. On a well-to-wheel basis, the cleanest and most efficient way to produce hydrogen is via biomass, so the news is a set-back for the biohydrogen community. But then again, biomass can be used more efficiently as electricity for battery cars. Canada.com - November 21, 2007.

    OPEC leaders began a summit today with Venezuelan President Hugo Chavez issuing a chilling warning that crude prices could double to US$200 from their already-record level if the United States attacked Iran or Venezuela. He urged assembled leaders from the OPEC, meeting for only the third time in the cartel's 47-year history, to club together for geopolitical reasons. But the cartel is split between an 'anti-US' block including Venezuela, Iran, and soon to return ex-member Ecuador, and a 'neutral' group comprising most Gulf States. France24 - November 17, 2007.

    Canada's Gemini Corporation has received approval to proceed into the detailed engineering, fabrication and construction phases of a biogas cogeneration facility located in the Lethbridge, Alberta area, the first of its kind whereby biogas production is enhanced through the use of Thermal Hydrolysis technology, a high temperature, high pressure process for the safe destruction of SRM material from the beef industry. The technology enables a facility to redirect waste material, previously shipped to landfills, into a valuable feedstock for the generation of electricity and thermal energy. This eliminates the release of methane into the environment and the resultant solids are approved for use as a land amendment rather than re-entering the waste stream. In addition, it enhances the biogas production process by more than 25%. Market Wire - November 7, 2007.

The Renewable Fuels Agency will be responsible for the day to day running of the Renewable Transport Fuels Obligation, coming into force in April next year. By 2010, the Obligation will mean that 5% of all the fuels sold in the UK should come from biofuels, which could save 2.6m to 3m tonnes of carbon dioxide a year. eGov Monitor - November 5, 2007.

    Prices for prompt loading South African coal cargoes reached a new record last week with a trade at $85.00 a tonne free-on-board (FOB) for a February cargo. Strong Indian demand and tight supply has pushed South African prices up to record levels from around $47.00 at the beginning of the year. European DES/CIF ARA coal prices have remained fairly stable over the past few days, having traded up to a record $130.00 a tonne DES ARA late last week. Fair value is probably just below $130.00 a tonne, traders said. At this price, some forms of biomass become directly competitive with coal. Reuters Africa - November 4, 2007.

The news was announced during a meeting of the Haryana Renewable Energy Development Agency (HAREDA). Six pilot plants have demonstrated the efficiency and practicability of small-scale biomass gasification. Capital subsidies will now be made available to similar projects at the rate of Rs 2.5 lakh (€4400) per 100 KW for electrical applications and Rs 2 lakh (€3500) per 300 KW for thermal applications.

The bioeconomy at work: researchers develop 'nanohybrid' bioplastic that biodegrades much faster

Scientists in New York are reporting the development of a new biodegradable 'nanohybrid' plastic that can be engineered to decompose much faster than existing renewable plastics used in everything from soft drink bottles to medical implants. The study appears as an open access article in the journal Biomacromolecules, a publication of the American Chemical Society.

The plastic is a modified form of polyhydroxybutyrate (PHB), a promising biodegradable thermoplastic produced by the fermentation of renewable biomass by bacteria (previous post) that has been widely hailed as a 'green' alternative to petroleum-based plastic for use in packaging, agricultural and biomedical applications. Although commercially available since the 1980s, PHB has seen only limited use because of its brittleness and unpredictable biodegradation rates.

In the new study, Pralay Maiti, Carl Batt, and Emmanuel Giannelis from Cornell University's Department of Materials Science and Engineering compared the strength and biodegradation rates of raw PHB to a modified form of PHB that contains nanoparticles of clay or 'nanoclays'. One advantage of clay nanocomposites is their improved barrier properties while retaining the flexibility and optical clarity of the pure biopolymer. The use of such particles has been reported in biodegradable aliphatic polyester nanocomposites, but this is the first time they were introduced into PHB/layered silicate nanocomposites:

The main objective of the researchers was to study the effect of nanoclays on biodegradation. Although the biodegradation of neat PHB enzymatically and in seawater was already studied, this is the first report of biodegradability of PHB nanocomposites.

Biodegradation tests were carried out at room temperature (20 C) and at 60 C. The scientists found that the modified PHB was both stronger and decomposed faster than regular PHB. The nanohybrid PHB decomposed almost completely after seven weeks, while its traditional counterpart showed almost no decomposition (image, click to enlarge). They also showed that degradation could be fine-tuned by adjusting the amount of nanoparticles added.

The study is the first report of the biodegradation of PHB nanocomposites and could lead to wider use of PHB plastics, the scientists say.

Nanotechnology and the field of nano-enhanced bioplastics is having concrete results. Recently a specialty chemicals company announced that it succeeded in embedding dispersible nanoparticles into polylactic acid (PLA) based bioplastics which makes them considerably stronger and less hazy (previous post). This is a much needed improvement, overcoming one of the key weaknesses of PLA bioplastics.
