Une étude très intéressante sur l’amélioration de la stabilité du PLLA lors de sa mise en oeuvre à l’aide d’un “waterscavenger”; un poly-carbodiimide plus réactif à l’hydrolyse que le PLLA !

American bio-plastics producer Cereplast is gearing up for greater volumes and restructuring its manufacturing operations with the start-up of production at its Seymour, Indiana, facility where it will now concentrate all its core manufacturing assets. The restructure is intended to cut manufacturing costs and enable delivery of polymers in larger quantities. Chairman and chief executive Frederic Scheer described the move as accelerating the company’s transition from small manufacturer to thriving, full-scale bioplastics company.

Natureplast est un fournisseur Français de PLA, PHA et de TPS. Une gamme de PLLA sans OGM est également disponible !
Leur site internet est très didactique, on y trouve notamment des définitions claires de la biodégradabilité, de l’oxo-dégradabilité et de la bio-désintégration.
Plastic industry is taking a closer look at the origin of biopolymers. Indeed we can now find “non GMO based” PLLA or “non edible crop based” polymers !
Here are a couple of interesting posts on this point: Lisez la suite de cette entrée »
Le nombre d’industries produisant des bioplastiques en Allemagne est en forte augmentation !
BASF a déjà annoncé la création de deux nouveaux sites. A présent c’est “Plantic” (Australien) qui met en place un centre de thermoformage pour l’amidon, et ”Pyramid bioplastic” (Suisse-Allemand) qui sont intéressés par produire du PLLA !
Archer Daniels Midland Company (ADM) and PolyOne Corporation have recently announced that they have agreed to collaborate on the development of bio-based plasticizers for use in polymer formulations.
Article très intéressant, car on sait combien il est difficile actuellement de trouver sur le marché des plastifiants adaptés aux cahier des charges des bioplastiques, c’est à dire des plastifiants qui soient biodégradables et/ou biosourcés.
Sainsbury’s has launched compostable packaging for wet products, which will be tested in 40 of its stores, Recycling & Waste Management News & Information reports. The retailer teamed up with Amcor Flexibles to use a compostable film in its So Organic Wild Rocket range. The packaging took Amcor Flexibles 18 months to develop and has passed all health and safety food contact legislation.

Un nouvel article issu de PakBec, très intéressant, relate la vision de Nature Works sur le développement de son marché! Il s’agit en fait d’une réponse de NW à un article du Guardian remettant en cause l’utilisation des biopolymères dans les emballages. des déclarations très intéressantes sont cepenandt à vérifier: “la quantité de CO2 engendrée par la production de PLLA serait deux fois plus faible que celle de la production des polymères synthétiques, le PLLA serait recyclable à volonté, …“
L’article initial du guardian souligne les désavantages des bio-plastiques (dits compostables) ainsi que des oxo-dégradables (dits fragmentables).

D’ailleurs voici l’article sur “The guardian” “Sustainable bio-plastic can damage the environement” http://www.guardian.co.uk/environment/2008/sep/23/waste.pollution
Et la réponse de Natureworks : http://www.guardian.co.uk/environment/2008/sep/23/waste.pollution
Cet article est à mettre en parralèle de l’un de mes ancien posts, il est cependant beaucoup plus complet. A lire sur PakBec. L’article rappelle comment la ville de Sherbrooke veut être reconnue comme pôle environnemental spécialisé dans les bioindustries.

European Polyemer Congress
Sessions will cover the whole range of polymer science comprising contributions on synthesis, characterization, processing,
application and theory.
session 1:
Polymers from bioresources
This session is focussing on macromolecules made by biological systems or from biological resources. Contributions with respect to analysis/characterization, synthesis/transformation, process technology and modelling are welcome.
EPF’09 – European Polymer Congress
12–17 July

Graz, Austria
Organic Waste Systems (OWS) is a private company under Belgian law, constituted in 1988 with a capital of 1.240.000 Euro. OWS is specialised in biological treatment of solid and semi-solid organic substrates by means of anaerobic digestion. OWS has developed the DRANCO, SORDISEP and DRANCO-FARM processes.

ProcuraSell scooped theWelsh Assembly Government’s Business Start-up Award for the development of its compostable trays designed for use by food retailers, the catering industry and others.
The company, which has offices in Redwither Tower on Wrexham Industrial Estate, makes its newcompostable trays from natural fibre left over from the sugar refining process. The trays aremade for the company in China and are said to be an ideal replacement for packaging materials such as plastic and aluminium.

Biodegradable plastic made from renewable resources always sounds better than petroleum-based plastics, right? Well, kind of. We know that most bioplastics aren’t biodegradable in the sense that you can toss it in a compost bin and expect it to quickly disintegrate. Bioplastics still often have to go through an energy-intensive recycling process to get them to fully degrade. So, does this make them equally undesirable? Exactly how do they measure up to conventional plastics?
A new study by researchers at the University of Hawaii, Honolulu aimed to find out, and they discovered a few leg-ups that bioplastics have over conventional plastics during the production phase, primarily that bioplastics emit fewer carbon emissions when manufactured.
Ever since plastics revolutionised product manufacturing in the late 19th century, these materials have grown to dominate modern consumerism. From the computer keyboard to outdoor furniture, plastics are one of the most versatile materials available to manufacturers. However, they may no longer be one of the cheapest materials available. Oil price hikes are seeing to that, and pushing science to search for new, low-cost, ‘greener’ options to fill the world’s need for versatile plastics.
Some product alternatives to plastic have already travelled the path to market, such as the edible chocolate trays made of corn starch developed by CSIRO and other Food and Packaging Cooperative Research Centre (CRC) partners and now manufactured by biodegradable packaging company Plantic. Overseas, similar biodegradable polymer materials are being used for plastic wrap and supermarket meat trays.
Demand for biodegradable plastic in the U.S. is forecast to expand nearly 16 percent per year to 720 million pounds in 2012, valued at $845 million, according to a new report by market research firm The Freedonia Group.
According to the report, entitled “Biodegradable Plastics”, “Polylactic acid (PLA) demand will present good opportunities through 2012, reflecting price declines, improved product performance and greater processor familiarity.”

Chances are, parts of your car are made from Ontario-grown corn and soybeans.
Didn’t know that?
Not many people do, but it’s a growing reality as auto parts makers look for cheaper, more environmentally friendly alternative materials.
And local farmers are getting in on a piece of the action.
“Our goal is to have 300 kilograms from agriculture in every vehicle,” Gord Surgeoner, president of Ontario Agri-Food Technologies, told the Western Fair Association last week.

Current European consumption of bioplastics is limited, at between 75,000 and 100,000 tonnes, industry association chairman Harald Kaeb put forward at an Interpack conference on the topic. While this is clearly miniscule compared with a figure of nearly 50 million tonnes for standard plastics, the bio sector does offer growth rates in excess of 25%, he noted.

De nouveau un billet autour de la remise en question des bioplastiques, sont abordés:
En revanche, et c’est dommage, rien n’est dit sur la comparaison des cycles de vie et du potentiel de synthèse chimique …
Par ailleurs de nombreux exemples sont donnés
