Cardia Bioplastics will supply major Chinese manufacturer Ben's Land Baby Articles Corp Ltd with a new compostable moisture barrier film ("Bio-Film") for the manufacture of a range of baby diaper/nappy and feminine hygiene products. The Australian sustainable resins and finished products supplier, Cardia Bioplastics was approached by Ben's Land to collaborate in the development of this specialist film product following demand from United States and European customers for more environmentally friendly hygiene products. Testing confirmed that, compared to conventional plastic films, Cardia Compostable "Bio-Film" provides the required high performance moisture barrier to prevent leaking, facilitates breathability to keep skin drier, and is soft for comfort. "Bio-Film" is part of the patented Cardia Compostable resins range. These resins are manufactured from renewable resources and are certified as fully compostable to international sta

Building on an enzyme found in nature, researchers at Rensselaer Polytechnic Institute have created a nanoscale coating for surgical equipment, hospital walls, and other surfaces which safely eradicates methicillin resistant Staphylococcus aureus (MRSA), the bacteria responsible for antibiotic resistant infections. "We're building on nature," said Jonathan S. Dordick, the Howard P. Isermann Professor of Chemical and Biological Engineering, and Director of Rensselaer's Center for Biotechnology & Interdisciplinary Studies. "Here we have a system where the surface contains an enzyme that is safe to handle, doesn't appear to lead to resistance, doesn't leach into the environment, and doesn't clog up with cell debris. The MRSA bacteria come in contact with the surface, and they're killed." In tests, 100 percent of MRSA in solution were killed within 20 minutes of contact with a surface painted with latex paint laced with the c

DuPont Apollo thin-film photovoltaic modules are used for commercial rooftop and large-scale applications. The solar modules can generate more wattage output under diffuse lighting conditions and consume only about 1/200 the silicon of traditional crystalline silicon solar cells, resulting in shorter energy payback times. DuPont™ Tyvek® Weatherization Systems are part of a system created to seal buildings from the inside and out. Tyvek® is an ENERY STAR partner that helps enhance the energy efficiency, indoor air quality and overall comfort of a home or commercial building. Tyvek®, which combines properties of paper, film and fabric, also is an ideal choice for reusable bags by environmentally conscious customers. DuPont™ Energain® decreases the amount of energy used in a building by controlling temperature levels and thus reducing the need for cooling and heating. The result is major cost savings and reduced carbon dioxide (CO 2 ) emissions. DuPont™ Sorona® renewably sou

Deltron’s manufacturing subsidiary Elasco, Inc., which manufactures engineered plastics and polyurethanes, has prepared eco-friendly skateboard wheels for Sector 9, a manufacturer of skateboards and apparels. Elasco formulated and manufactured Biothane brand polyurethane wheels made with soybean-based polyols, which delivers similar performance as petroleum-based polyurethane. Polyols are produced from pressed soybeans with isocyanate and other ingredients to create new polymers. Soy-based polyol resins are claimed to reduce carbon emissions from the manufacturing process by 36%, require less energy to produce, and are free of volatile organic compounds. Elasco provides complete design and manufacturing services, including prototype work, mold and tooling design, manufacturing, custom casting, plastic injection molding and proprietary polymer mixing.

Prescott's Manufacturing Inc.'s new line of sterile knob covers for surgical microscopes are made of Radel® R-5100 polyphenylsulfone ( PPSU ) resin from Solvay Advanced Polymers, LLC, for exceptional autoclavability and toughness. The high-performance thermoplastic also delivers more efficient and faster processing than the incumbent thermoset material. The knob covers are extensions of the microscope handle and are used to manipulate the microscope during surgery. The reusable covers come in repeated contact with medical personnel and must be sterilized after each procedure. Radel PPSU resin withstands repeated autoclaving - up to 1,000 cycles - while maintaining its toughness and impact resistance. "We evaluated a range of resins and found that Radel PPSU was superior in terms of autoclavability," said Philip Schloesser, Engineer for Prescott's Manufacturing. By tapping into its expertise in injection molding, Prescott's hoped to gain impr

A student at Germany’s Offenbach University of Art and Design, Alice Gruhle, has designed an innovative lamp, namely “Polymorph” lamp by taking its inspiration from origami and Lego™ concept. This “Polymorph” lamp, that can be easily adapted into different sculptural shapes, is formed from diamond-shaped modules made from 6mm-thick polypropylene ( PP ) sheets by using an injection molding process. Then the injected molded PP modules are linked together in order to allow folds at the joint. The first lamp prototype has been created with 150 modules, creating a cocoon-like hanging lamp. This innovative lamp concept has already won a competition at the Hochschule für Gestaltung Offenbach. It has also been featured in several German design magazines and has been showcased at the latest Euromold exhibition.

All over Europe, electrical and electronic scrap is the waste stream showing the highest growth rates. Since electronic equipment contains the most varied kinds of materials, the recycling of such waste involves high demands with respect to separation and sorting processes. The German plant manufacturer MeWa builds state-of-the-art recycling plants for large international waste management companies. In the United Kingdom MeWa realised a plant where old refrigerators, computers, vacuum cleaners, Hi-Fi systems, and other kinds of electrical waste are processed on two separate lines. For the recycling of high-quality plastics such as ABS ( acrylonitrile butadiene styrene ) or PC ( polycarbonate ) and of printed circuit boards MeWa uses three VARISORT N sorting systems made by S+S. "The decision to use E-Schrott Elektronic Waste S+S systems was based on the high output quality of these VARISORT systems. Only absolutely pure fractions can be sold at a good price in today&
