A lightweight multi-functional crankshaft cover in Royal DSM’s EcoPaXX high-performance polyamide 410 was top in the Powertrain category at the Society of Plastics Engineers Automotive Division Innovation Awards Competition and Gala in Detroit. The 70% bio-based EcoPaXX is made principally from topical castor beans and is 100% carbon neutral from cradle to gate. Castor oil is obtained from the Ricinus Communis plant, which grows in tropical regions on relatively poor soil, and does not compete with the food-chain.
The EcoPaXX crankshaft cover is produced by DSM’s automotive component specialist partner KACO in Germany for the latest generation of MDB-4 TDI diesel engines developed by the Volkswagen Group. The engines are fitted to various car models made by VW, Audi, Seat and Škoda. Dr. Lutz Wohlfarth from Volkswagen, and Marcio Lima from KACO were both at the Gala in Detroit to collect the SPE award.
Study: open trash burning worldwide significantly worsening air pollution; unaccounted for in emission inventories
August 28, 2014
Unregulated open trash burning around the globe is pumping far more pollution into the atmosphere than shown by official records. A new study led by the National Center for Atmospheric Research (NCAR) estimates that more than 40% of the world’s garbage is burned in such fires, emitting gases and particles that can substantially affect human health and climate change.
The new study provides the first rough estimates, on a country-by-country basis, of pollutants such as particulates, carbon monoxide, and mercury that are emitted by the fires. Such pollutants have been linked to serious medical issues. The researchers also estimated emissions of carbon dioxide, the most common greenhouse gas produced by human activity. Their paper is published in the ACS journal Environmental Science & Technology.
MIT team proposes process to recycle lead-acid batteries to fabricate solar cells
August 18, 2014
Researchers at MIT have devised an environmentally-responsible process to recycle materials from discarded automotive lead-acid batteries to fabricate efficient organolead halide perovskite solar cells (PSCs)—a promising new large-scale and cost-competitive photovoltaic technology. The process simultaneously avoids the disposal of toxic battery materials and provide alternative, readily-available lead sources for PSCs.
The system is described in a paper in the RSC journal Energy and Environmental Science, co-authored by professors Angela M. Belcher and Paula T. Hammond, graduate student Po-Yen Chen, and three others.

Critical review finds actual measurement data on segments of natural gas lifecycle sparse or lacking
July 08, 2014
After a critical review of the literature on the air impacts of increased natural gas acquisition, processing, and use, a team of US researchers has determined that that actual measurement data on various individual segments of the natural gas life cycle are sparse or critically lacking.
National and state regulators primarily use generic emission inventories to assess the climate, air quality, and health impacts of natural gas systems. These inventories rely on limited, incomplete, and sometimes outdated emission factors and activity data, based on few measurements, they found. In their paper, published in the ACS journal Environmental Science & Technology, they make a number of recommendations to maximize the benefits and minimize the negative impacts of the natural gas resource.
Ford tops 50 Best Global Green Brands list for 2014; Toyota, Honda and Nissan 2nd, 3rd and 4th
June 25, 2014
Automakers took the top four slots in the 50 Best Global Green Brands list for 2014, published by Fortune magazine in conjunction with the consulting firm Deloitte and Interbrand. Ford bumped last year’s leader, Toyota, to take the top spot. Toyota came in second, followed by Honda and Nissan. Panasonic was in fifth place.
The list was first created in 2011. This year’s nominees were drawn from Interbrand’s annual Best Global Brands report, which ranks the world’s 100 most valuable brands. The 50 companies on Best Global Green Brands list were ranked in two ways: on the strength of their sustainability initiatives and on how the public perceives those efforts.

May 27, 2014
|New two-wet monocoat paint process. Click to enlarge.|
Ford began production of the North American Transit at Kansas City Assembly Plant on 30 April, and vans will be available in US and Canada this summer. Transit vehicles built in Kansas City are the first to use a new two-wet monocoat paint process developed by Ford and its paint suppliers. The technology results in more durable paint, uses less energy and water, and reduces carbon dioxide and particulate emissions compared with conventional paint processes.
The new paint was subjected to testing simulating typical conditions the vehicle will see over 10 year—e.g., resistance to chipping and scratching, pollutants and sun exposure. Data from preliminary advanced weathering testing indicates that paint applied with the new two-wet technology will retain 90% of its gloss at four years in service compared to 1% gloss retention for paint applied using a conventional monocoat process.

Honda marked the opening of Honda Smart Home US, showcasing technologies that enable zero net energy living and transportation, including Honda’s home energy management system (HEMS), a proprietary hardware and software system that monitors, controls and optimizes electrical generation and consumption throughout the home’s microgrid.
The home, located on the West Village campus of the University of California, Davis, is capable of producing more energy on-site from renewable sources than it consumes annually, including enough energy to power a Honda Fit EV for daily commuting. Honda Smart Home is expected to generate a surplus of 2.6 MWh of electricity over the course of a year, while a comparable home will consume approximately 13.3 MWh. The home’s occupant will be able to use less than half of the energy of a similarly sized new home in the Davis area for heating, cooling and lighting. The home is also three times more water-efficient than a typical US home.
