China Burns Corn Stalks and Cotton Stalks to Generate Electricity
A small power plant that burns corn stalks and cotton stalks to generate electricity for nearby villages and steam for a neighboring industrial complex is being built in Boxing, China and should be open next year. The plant would be ready sooner, but only four companies in China make the specialized precision boilers that the biomass plant requires. The same utility company, building the green plant in Boxing, opened a coal-fired plant in southernmost China...[MORE]

Grocer Pushes Earth-Friendly Store Design
Hannaford Bros. Co., a Maine-based grocery chain, announced plans for a green supermarket. Plants will be grown on the store's roof to add insulation and control storm water.
