From Science & Research

From Science & Research Financial considerations Ongoing work will evaluate the financial performance of the above CW biorefinery system. Based on recent market prices for ethanol and LDPE [6, 7], process costs for converting ethanol to LDPE would have to be less than ~###COLUMNCONTENT###.20/kg LDPE to offer a competitive use of ethanol without subsidy. The financial attractiveness of LDPE production from CW is affected by the high market price of ethanol, which results in part from existing policies that mandate its use as a transportation fuel. Currently, similar support is not available to biomass-derived chemicals or plastics. Summary Conversion of CW to renewable LDPE is demonstrated to have the potential to significantly reduce life cycle GHG emissions compared to LDPE produced from fossil fuel or sugar cane. Utilizing global CW supply for producing LDPE would provide up to 3.5% of worldwide demand [8] and reduce emissions by approximately 3.4 million tonnes CO 2 eq./yr, while simultaneously addressing environmental concerns related to CW disposal practices.

Chinaplas Review Chinaplas 2013 took place from May 20 - 23 in the southern Chinese city of Guangzhou, being Asia’s No. 1 and the world’s no. 2 plastics and rubber exhibition. More than 2900 exhibitors from 38 countries showed their expertise on 220,000 m² of floor space. Chinaplas expected to attract more than 115,000 Chinese and foreign visitors from 150 countries looking to learn about, exchange and source chemicals and raw materials and a variety of plastics and rubber machinery. In a special Bioplastics Zone in hall 12.2 again more than 30 companies were listed in the show catalogue to present their products and services in terms of biobased and/or biodegradable plastics. Still there were a significant number of companies offering traditional PE or PP filled with starch, straw or bamboo and it could be argued whether or not such blends should be considered as bioplastics. The 5th International Seminar on Bioplastics Applications took place on May 18-19 in a Guangzhou hotel, sharing the latest trends, government policy on bioplastics and lowcarbon economy, and the technologies of the bioplastics industry. Key material suppliers, manufacturers, professional research organizations and machinery suppliers were invited to offer their expertise. As in previous years, the booth of bioplastics MAGAZINE was very well visited. We had lots of interesting talks and many visitors seriously interested in bioplastics. The 1000 copies of bioplastics MAGAZINE that were printed specially for this show were gone after two and a half of the four very busy days at Chinaplas. In addition to the Chinaplas Preview that we published in the last issue, we now add some more small reports about selected companies from the Bioplastics Zone in Guangzhou. Hubei Guanghe Bio-technology Co., Ltd. Since 2006 Hubei Guanghe Bio-technology has been engaged in the development of ultra-high molecular weight PLA compounds in cooperation with different universities and colleges. At Chinaplas they presented four different grades: GH401 for injection moulding, GH501 for sheeting, GH601 for stretch blow moulding and GH701 for film. Products made from the GH materials include disposable tableware, hotel consumables, agricultural applications and bags. All GH reins are OK-Compost certified (EN 13432). Jiangsu Jinhe Hi-tech Co., Ltd This company is located in Yangzhou (Jiangsu province) near Shanghai. The main products are starch and straw filled polypropylene. The materials are well suited for injection mouding of high quality products such as cutlery, plates and bowls or even coat hangers, child chairs and toothbrushes. Guangzhou Bioplus Materials Technology CO., Ltd Bio-plus Materials Technology is specialized in the development of modified PLA. The predecessor, Junjia Technology Co., Ltd., was founded in 1998 and in 2006, the company started to step into the field of modified PLA and its application. Their current focus is on property improvement of PLA, especially on heat resistance and impact strength. By now, we have already made great progress on its heat resistance. Bioplus’ products include grades for injection moulding and such for extrusion and thermoforming with heat deflection temperatures up to 100°C without inorganic filers and such with white inorganic fillers. Special grades for foam appications and for bottle blowing as well as such for melt spinning are also available. bioplastics MAGAZINE [03/13] Vol. 8 31
