Epidra, a private firm in Athens, Ga., is exploring larger-scale applications, such as pyrolysis systems that can produce both enough energy to power a tractor and a biochar tailored to improve particular soils. "If you're going to grow food, you have to do it responsibly," says Bob Hawkins, Eprida's project manager. "And one way of doing that is to use it to generate sustainable energy." A prototype can turn a ton of ground peanut shells into 600 lb. (270 kg) of biochar, with energy as the bonus...
...policies. Some cutbacks are inevitable, he believes, but "sustainable development is now an integrated part of doing business. It's not a question of environment versus business. It's a business issue, and if companies don't address it, they will have problems with their license to operate and grow." His business council has been working with most of the leading players in the cement, metals and mining, and electric-utility industries to define specific targets for such things as CO2 emissions and responsible use of fuels and materials that the firms then commit to meet...
...year, and consumer luminaries alone - excluding the market for bulbs - is almost one-third of that. Philips is moving fast to expand from its traditional European base. Bijlsma reckons the firm's sales of LED and other low-energy lighting will double every year in emerging markets, and grow "at a fast pace" in mature markets. Philips is targeting Latin America, and also Asia, where it is planning branded showrooms in stores...
...Through air that shimmers in the blast furnace of a July day, you can see how far Mead's water level has fallen. White bathtub rings of mineral deposits, measuring high-water marks that grow less high every year, circle the edges of the reservoir. Today Mead's water level is 1,108 ft., down from more than 1,200 ft. in 2000. (The official drought level is 1,125 ft.) If the water continues to decline, says marine geophysicist Tim Barnett of the Scripps Institution of Oceanography, "buckle up." Barnett co-authored a study estimating a 50% chance that...
...reason for the world's growing water woes is evident in the numbers. The planet fairly sloshes with water--326 quintillion gal. of it--but only 0.014% of that is available for human use. The rest is nonpotable ocean water or inaccessible freshwater, most of it frozen in polar caps. And the available water we do have is far from evenly distributed. About 1.1 billion people have no access to clean water, and half the planet lacks the same quality of water that the ancient Romans enjoyed. And while the amount of water on the planet remains fixed, the number...
