Four Canadian researchers make a case that lignin could become an important feedstock for bioplastics.
“Considering the current production of lignin from pulp and paper industries as well as potential future production from lingocellulosic ethanol industries, it is estimated that around 300 M ton/year of lignin will be produced in North America,” they said in an article presented at the Annual Technical Conference (Antec) of the Society of Plastics Engineers (SPE) held concurrently last month with NPE2012 in Orlando, FL. “Lignin is now considered as an inexpensive co-product and it is mainly used as a boiler fuel. The value of lignin can be better realized as a good source for new outlets such as renewable resource based materials.”

Styrene is one of the major building-block chemicals used to make many of the rubbery polymers and plastic materials we use today. More than 6 billion tons of it is manufactured each year in the United States alone, most of which goes into producing insulating materials, automobile tires, footwear, medical devices and hundreds of other widely used products. The problem is that all styrene is currently derived from a dwindling resource – petroleum – and its production requires one of the most energy-intensive processes in the petrochemical manufacturing industry. More than three metric tons of steam is necessary to produce just one metric ton of styrene. That excessive energy consumption also produces significant amounts of carbon dioxide, contributing to the detrimental buildup of greenhouses gases in the atmosphere.
At Arizona State University, David Nielsen and Rebekah McKenna are seeking ways to make styrene – and other common petrochemicals – using renewable resources. They want to produce materials that are more sustainable, require less energy to produce, and alleviate negative environmental impacts when they are manufactured. Nielsen is an assistant professor of Chemical Engineering in the School for Engineering of Matter, Transportation and Energy, one of ASU’s Ira A. Fulton Schools of Engineering. McKenna is studying to earn a doctoral degree in chemical engineering. They’re experimenting with engineering microorganisms to act as catalysts for making styrene from renewable resources – in this case biological materials, like sugars from plants.

German researchers from different institutes in microbiology, biochemistry and biotechnology found an alternative to produce Poly-3-hydroxybutyrate (PHB).
This study shows that, by introducing the bacterial PHB pathway of R. eutrophaH16 into the diatom Phaeodactylum tricornutum, PHB production is feasible in a microalgal system.
The PHB is a polyester with thermoplastic properties that is naturally occurring and produced by such bacteria as Ralstonia eutropha H16 and Bacillus megaterium. The PHB is biodegradable, and its production is not dependent on fossil resources making this bioplastic interesting for various industrial applications.
PHB is synthesized from acetyl-CoA by the action of three enzymes: a ketothiolase, an acetoacetyl-CoA reductase and a PHB synthase. Under optimal conditions bacteria such as Ralstonia eutropha H16 can produce up to 80 % PHB of cellular dry weight, and some companies have specialized on commercial PHB production (e.g.Metabolix Inc., Micromidas Inc.). Nevertheless, costs for PHB production by bacterial fermentation are still very high, which brought plants into focus as photosynthesis fueled low-cost production system. The three bacterial enzymes were expressed in the cytosol or targeted to different compartments of the plant cell leading to high amounts of PHB accumulation in the plastids of Arabidopsis thaliana (up to 40 % of dry weight). However, due to stunted growth and infertility, these plants were not suitable for large-scale cultivation. Read the rest of this entry »

Since its creation in 2009 Bamboo Fibers Technology (BFT) still develop its activities to propose more and more solutions to valorize every single part of its plant.
BFT news: Interview of M. Malvy, BFT CEO
This year, the rate of BFT bamboo fibers in biopolymers has exceeded 50 % which represent a great march. BFT developments enabled to obtain a great drop in mechanical performance of bamboo fiber reinforced composites: “We have exceeded mechanical performance of some glass fiber reinforced petroleum based matrix composites but with a 40% lower density”, said M. Malvy, the BFT CEO.
Besides, BFT develop fiber grease treatment to improve the fiber/matrix interface and so the mechanical properties but also thermal performances, hardness, impact resistance and electric conductivity.
In a long fibers way, BFT is testing new half-finished products in order to realize non-woven, roving and yarn.
The company has just opened a green chemistry department to develop new green resins, structural foams, additives, cosmetics, and also some biologic filters and flame retardant particles.
BFT also continue to reinforce its presence in its field of references like aeronautics, automotives, and armament.

For Christmas this year, British retailer Marks & Spencer will sell its Swiss chocolate range, especially mince pies, in innovative biodegradable corn starch-based organic plastic trays manufactured by Plantic Technologies. This bioplastic made from starch, is claimed to be completely compostable; it becomes moist under running water, dissolves within minutes and finally breaks down completely in three weeks.
The strain of the corn used is non-genetically modified. The packaging conforms to European standards (EN13432), and is made from renewable and sustainable resources (non-GM corn starch). Plantic uses polymers and its raw materials that are based on industrial starch with film-forming properties. This technology was developed by Australia’s Co-operative Research Centre for International Food Manufacture and Packaging Science with expertise from Swinburne University, the University of Queensland and the CSIRO.

Plaxica is a privately held technology company developing a new generation of polymers derived from sustainable resources. It was founded in 2008 and is based in London.
Plaxica is developing the next generation of polylactic acid (PLA) polymers from sustainable resources, which are expected to have improved physical properties compared with first generation biopolymers, a smaller environmental footprint, be fully recyclable, and cost competitive with current oil-based alternatives. These next generation PLA polymers are likely to replace conventional oil-derived products like PET, polypropylene and polystyrene in a range of textile, automotive, electronics, household and packaging applications. The novel chemistry underpinning this technology came from the laboratories of Professor Vernon Gibson FRS and Dr Ed Marshall at Imperial College London, one of the world’s leading science and technology institutes.
Plaxica’s management team includes Chief Executive John Hamlin (formerly of BP) who has held several senior international business and technology positions, most of which were in the chemicals and polymers sector, and Chairman Philip Holbeche (ex-Chairman, Ceres Power plc) who has more than 20 years experience in the financing and growth of entrepreneurial companies.

Effect of clay organomodifiers on degradation of polyhydroxyalkanoates
Polymer Degradation and Stability
Volume 94, Issue 5, May 2009, Pages 789-796
Perrine Bordes, Elodie Hablot, Eric Pollet, Luc Avérous
Abstract
Ammonium surfactants are commonly used as clay organomodifiers in nanocomposites. Their effect on the thermal- and thermo-mechanical degradation of polyhydroxyalkanoates (PHAs) is reported. Two poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) grades were tested and compared to polyhydroxybutyrate (PHB). Thermal stabilities were determined from thermogravimetric data and determination of molecular weight changes after processing was performed. The data revealed that all surfactants enhance the PHBV degradation. The results also highlight the preponderant effect of the initial Mw rather than the HV content on the thermal stability. The thermo-mechanical study confirmed the role of surfactants and their different behaviour towards PHBV degradation. This study demonstrates that all surfactants enhance the PHA degradation since their decomposition products most likely act as catalytic agents.
