News 3rd WPC Congress

News 3rd WPC Congress Even in the current economic crisis international sales figures of Wood Plastic Composites (WPC) are increasing. The 3rd German WPC Congress in Cologne in early December wasn’t exactly a German congress as about 300 delegates from 26 countries met for this international industry get-together. The audience acted as the judging panel in deciding to give the WPC Innovation Award to STAEDTLER for a new sustainable pencil. The second and third places went to Hiendl for an assembly profile system and Qingdao HuaSheng for a thermally insulated siding (cladding) system for buildings. Today more than 1.5 million tonnes per annum of WPC are produced globally, mainly in North America (approx. 1 millon tonnes), China (200,000 tonnes), Europe (170,000 tonnes) and Japan (100,000 tonnes). In Europe Germany is the leading country with more than 70,000 tonnes of WPC, as well as being the most significant machinery manufacturers. The most important applications are found in the automotive sector as well as in deckings, i.e. outdoor floor coverings for patios or public places. WPC is establishing itself more and more as an alternative for tropical wood solutions. Award winning assembly profile system made with Hiendl NFC ® (photo nova Institut) However, although WPC incorporates up to 70% wood as a natural ingredient bioplastics MAGAZINE asked about the steps being taken towards using bioplastics as matrices. Helmut Hiendl, owner and CEO of the award-winning company Hiendl, firstly wanted to make a product that functioned properly. After this first, and successful, step of replacing 70% of the fossil based material by renewables (wood) they of course are now seriously looking at the remaining 30% - the matrix. Helmut Hiendl indeed sees that some of what he called ‘green plastics’ could be used in his products. Dr. Matthias Schulte of WPC converter Werzalit tempered this view a little by commenting that feasibility and marketability must be checked, but basically WPC with biobased polymers will come. Extrusion and compounding machinery maker Reifenhäuser, represented by Dieter Thewes, Head of Business Area Extrusion Center, sees an increasing use of biopolymers, now that more production capacity is being installed. Finally conference organizer and MD of the nova Institute Michael Carus added that WPC with biobased matrices will open up new potential applications. MT www.nachwachsende-rohstoffe.info SPI Bioplastics Council Position Paper on Oxo- and Other Degradable Additives The Bioplastics Council, a special interest group of SPI: the Plastics Industry Trade Association, recently announced the release of a position paper that questions the scientific validity of biodegradability claims made by producers of ‘oxo-degradable’ and ‘oxo-biodegradable’ products. The Council’s paper formally supports the point of view put forth by European Bioplastics in a July 2009 publication. Download the complete Position Paper from www.bioplasticsmagazine.de/201001 Producers of pro-oxidant and biological additives use the term ‘oxo- biodegradable’ to describe the resulting products made using the additives. This term suggests that the products can undergo rapid biodegradation under many different end-of-life conditions. However, the main effect of oxidation is fragmentation, not biodegradation, into small particles which remain in the environment for an undetermined amount of time. These results do not meet the internationally established and acknowledged standards and certifications that effectively substantiate claims on biodegradation under certain specific endof-life conditions. “In 2010 we made a pointed decision to insist on bringing clarity to the bioplastics market,” said Bioplastics Council Chair Frederic Scheer, CEO of Cereplast, Inc. “Allowing the brand owner, retailer or ultimately the consumer to decide what they consider a biodegradable product to be is risky, as they may lack the scientific knowledge to make an accurate decision. The Bioplastics Council supports legitimate scientific data as recommended by state and federal agencies and stresses the need for all companies, when making product claims, to work along guidelines defined by the Federal Trade Commission.” MT bioplastics MAGAZINE [01/10] Vol. 5

This includes comprehensive descriptions of the biopolymer market, the different materials and suppliers as well as production-, processing-, usage- and disposal properties for all commercially available biopolymers. The unique book represents an important and comprehensive source of information and a knowledge base for researchers, developers, technicians, engineers, marketing, management and other decision-makers. It is a must-have in all areas of applications for raw material suppliers, manufacturers of plastics and additives, converters and film producers, for machine manufacturers, packaging suppliers, the automotive industry, the fiber/nonwoven/textile industry as well as universities. Content: • • • • • Definition of biopolymers Materials classes Production routes and polymerization processes of biopolymers Structure Comprehensive technical properties Comparison of property profiles of biopolymers with those of conventional plastics Disposal options Data about sustainability and eco-balance • • • • • • • • • • Important legal framwork Testing standards Market players Trade names Suppliers Prices Current availabilities and future prospects Current application examples Future market development • • Rainer Höfer (Editor) Sustainable Solutions for Modern Economies ISBN: 978-1-84755-905-0 Copyright: 2009 / Format: Hardcover / 497 pages Sustainable Solutions for Modern Economies is an essay to reflect the aspects of sustainability in the different sectors of national and global economies, to draft a roadmap for public and corporate sustainability strategies, and to outline the current status of markets, applications, use and research and development for renewable resources. The book brings up philosophical aspects of the relationship between man and nature and highlights the key sustainability initiatives of the chemical industry. The position and the systemic role of the financial market in the economic circuit is depicted in one chapter as well as recently developed key performance indicators for the sustainability rating of companies. The eco-efficiency analysis is described as a management tool incorporating economic and environmental aspects for the comprehensive evaluation of products over their entire life-cycle. Another chapter describes a holistic approach to define sustainability as a guiding principle for modern logistics. Consumer behaviour and expectations, indeed, are crucial aspects to be considered in this book when dealing with further development of the sustainability concept. The achievements of food security are specified at a global level as a key element of sustainable development. Energy economy and alternative energies are key challenges for society today, dealt with in a separate chapter. Tens of millions of years ago, biomass provided the basis for what we actually call fossil resources and biomass again is by far the most important resource for renewable energies today. The efficient complementation and eventual substitution of fossil raw materials by biomass is the subject matter of green chemistry and is comprehensively described. The chapter „Biomass for Green Chemistry“ in particular highlights the potential of sucrose, starch, fats and oils, wood or natural fibres as building blocks and in composites of bio-based plastics and resins. Reduction in greenhouse gas emissions, energy and water usage are examples of the benefits brought about by greener, cleaner and simpler biotechnology processes, comprehensively dealt with in the last chapter „ White Biotechnology“. This includes PLA as one bioplastics example for White Biotechnology. Order your english copy now and benefit from a prepub discount of EUR 50.00.
