86VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the prot

19Freestyle motorcycle riding in the French Alps film is gorgeous

Of the world's innumerable natural wonders, the French Alps are particularly spectacular. Stretching along the border between France and Italy, the mountain chain offers exceptional vistas and, for braver folk, incredibly challenging terrain. Freestyle trials rider Julien Dupont recently brought a few friends out for a day of playing in the mountains, and Ride the World Productions tagged along to film the whole event. The camera crew spent some time playing with its own toys, including a camera

5DuPont to sell $4B auto paint business?

Even though DuPont's automotive paints, or "performance coating," division brought in 12.1 percent of the firm's 2010 revenue, the pretax operating-profit margin was only seven percent, said to be about "half the corporate average." With the highly diversified firm making plays in more lucrative "megatrend" areas, Automotive News reports that DuPont has retained Credit Suisse to find a buyer for its two coatings divisions valued at $3-4 billion.

AddGenencor mixes up enzyme cocktail to boost cellulosic ethanol production

International enzyme development firm Genencor, a division of Danisco A/S, has announced it's now mixing up the fourth enzyme cocktail in its trademarked Accellerase line. Called Accellerase Trio, Genencor says that this latest enzyme is designed to boost production of cellulosic ethanol from non-food feedstocks. More specifically, Accellerase Trio is an enzyme cocktail optimized to break down C5 and C6 sugars in biomass feedstocks, improving cellulosic ethanol yields by up to 20 percent over Ge

AddDupont looking to corner U.S.' cellulosic ethanol industry with acquisition of Dansico

Nestled in the foothills of the Great Smoky Mountains is the town of Vonore, TN. While it's not exactly the type of city that one would associate with cutting-edge cellulosic ethanol production, it is here that DuPont, the U.S. chemical company, is trying to buy Danisco's joint-owned facility for nearly $6 billion in an attempt to gain a fair amount of control over the U.S.' cellulosic ethanol industry.

81Americans like White, the world likes Silver in new Color Popularity Report

DuPont has released its annual Color Popularity Report, and for the first time has converged data from across the globe to create a worldwide report on how we, as a species, prefer our cars to be colored. OK, maybe that's a bit hyperbolic, but the new worldwide report confirms that Black, Silver and White reign supreme regardless of borders. The three colors are tightly packed in North America, where White is most popular at 17.8 percent with Black (17 percent) and Silver (16.8 percent) not far

17DuPont chief calls on Detroit to make 'Car of the Future'... that uses his fuel

It's debatable whether or not now is the right time to make changes in the way our cars are made, with some believing that Detroit should follow the path it's already on and others claiming there couldn't be a better time to make major sweeping changes. Count DuPont head Chad Holliday among the latter. Holliday's so-called "Detroit Project" would challenge American automakers to introduce a new "Car of the Future" that would achieve 75 miles per gallon and run on butanol – an alcohol fuel

AddDupont and Genencor announce new cellulosic ethanol plant

Genencor, a subsidiary of Danisco A/S, and DuPont have announced a joint venture that promises cheaper cellulosic ethanol. Both companies will be investing $140 million in a plant that will use sugarcane bagasses and corn stover, although other sources such as straw will be used in the near future. A pilot plant will be ready by 2009. The joint venture integrates the proprietary DuPont pretreatment and ethanologen technologies with the innovative enzyme technology of Genencor. Cellulosic ethanol

AddDuPont and SAE say that environmental issues are the biggest challenge facing automakers

Seems like AutoblogGreen's been on to something these last couple of years as it relates to the greening of the automotive industry. For the first time in fourteen years, the annual DuPont Automotive/SAE survey of OEM and supplier designers and engineers, conducted by Consumer Insights, Inc, found that environmental concerns topped cost as the biggest hurdle automakers must overcome.

AddDuPont's Zytel can cut weight of auto components in half

DuPont has announced a new type of resin that can work as a metal substitute. The new Zytel® nylon resin has replaced steel in exhaust system parts on all Volkswagen vehicles built on the current Golf platform, cutting weight of the component by nearly 50 percent. The resin is used in the catalytic converter bracket to substitute a previous multi-assembled metal and rubber part, so the benefits are not only from the reduced weight but also in the ease of assembly. As stated in the press rele

47DuPont reports most popular color on earth

var digg_url = 'http://digg.com/autos/DuPont_reveals_most_popular_car_color_on_earth'; For seven long years, silver has reigned as the overall number one choice worldwide for car color. DuPont reports that those days are over, and the new color of choice is -- gasp -- white/white metallic. That means more people prefer white cars than silver or black cars, with white taking a decisive lead in countries like Mexico and Japan. A study done earlier this year found that 62-percent of cars sold ov

7Pricey Pickup: 1969 Rolls-Royce Silver Shadow truck for sale

All that money, and it looks like a lowered Ford Courier with a nice paintjob -- from the side, anyway. This Silver Shad-amino (Shadero?) has just undergone a two-year restoration by Florida's Foreman Motors. It'd be just the thing out on the Estate, cruising the grounds surrounded by sumptuous leather and wool with the Spirit of Ecstasy up on the prow. We think it's great; it's not like these particular Rollers are rare cars, anyway. The duPont Registry, want ads for those with excess filthy lu

AddDuPont Biofuels on track to commercialize its biofuel technologies, including biobutanol and cellulosic ethanol

This week at the Piper Jaffray Alternative Energy Symposium, which focused on industry and investment trends in solar, cleantech and biofuels, DuPont Biofuels Vice President and General Manager John Ranieri said that DuPont is well on its way to commercializing their biofuel technologies. These technologies include some of the lesser talked about fuels, such as biobutanol and cellulosic ethanol. They are doing this in cooperation with Pioneer, which is a subsidiary of DuPont.
