Better bugs to make plastics
MIT Technology Review    Share   Share on FacebookTwitterShare on LinkedinE-mail article
A startup that has successfully engineered bacteria to make common industrial chemicals is now using its technology to engineer organisms to make renewable fuel. OPX Biotechnologies, based in Boulder, Colo., says its strains of E. coli can be used to convert sugar to acrylic acid — a key component of paints, diapers, and adhesives — at lower costs than making it from petroleum. The bacteria-based process produces 75 percent fewer carbon-dioxide emissions than making the same amount from oil, and a single commercial plant using the process could reduce petroleum consumption by over 500,000 barrels per year.

Preparation and characterization of nanoclay-filled polymer blends
SPE Plastics Research Online    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Thermoplastic polyurethane (TPU) is attractive because of its high abrasion resistance, tensile and tear strength, flexibility, and shock-absorbing capabilities. However, it has certain disadvantages, including high cost, moderate thermal stability and mechanical strength, and limitations as regards to chemical resistance and processability. On the one hand, polypropylene (PP) is usually added to TPU to improve the thermal stability of the latter, as well as its chemical and mechanical properties (modulus, strength, hardness), processing performance and to reduce cost. On the other hand, TPU is blended with PP to improve the properties of PP (e.g., impact strength, adhesion and paintability/printability). Blends of TPU and PP are highly incompatible because of the compounds' large differences in polarity and the resulting high interfacial tensions. More

Crude oil may fall as supplies climb, survey shows
Bloomberg Businessweek    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Crude oil may fall this week on speculation that U.S. inventories will climb as fuel demand declines, a Bloomberg News survey showed. Seventeen of 30 analysts, or 57 percent, forecast crude oil will decline through Oct. 1. Nine respondents, or 30 percent, predicted little change, and four estimated prices will rise. Last week, 52 percent said crude would decrease. More

Recession is officially over, but anxiety lingers
The Washington Post    Share    Share on FacebookTwitterShare on LinkedinE-mail article
On the day that the Great Recession was officially declared to be part of history, President Obama confronted deepening angst from business leaders and ordinary Americans who have little faith that the recovery is for real. The determination that the U.S. recession ended in June 2009, made by a panel of private economists who are the arbiters of business cycles, confirms that the 18-month downturn was the longest recession of the post-World War II era.

Manufacturing probably cooled this month: US economy preview
Bloomberg    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Manufacturing probably cooled in September and consumer spending stabilized last month, underscoring the Federal Reserve's forecast of "modest" U.S. growth in coming months, economists said before reports this week. The Institute for Supply Management's factory index fell to 54.5 from 56.3 in August, according to the median of 63 forecasts in a Bloomberg survey ahead of the Oct. 1 report. Household purchases rose 0.4 percent last month, the same as in July, Commerce Department figures may show. More

PE, PP prices rising, buyers say
Plastics News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Higher feedstock costs have sent North American polypropylene prices higher since Sept. 1, while a push for margin improvement has done the same for polyethylene prices in the region in that same time frame. Regional PE prices are up an average of 5 cents in that period, while PP prices have bumped up an average of 3 cents . The PE move reverses a trend in which high density PE and linear low density PE prices had fallen an average of 12 cents per pound since May 1. More
