Waste to Energy

Inexpensive natural gas, increased renewable energy utilization, and ever-tightening environmental regulations have limited the use of waste feedstocks for power generation. But while often dismissed out of hand, with proper planning and understanding of the market, power producers can realize benefits from waste-to-energy projects. It was a tropically hot day at the plant, and it […]

Is waste-to-energy the best greenhouse gas fighter among electric generating technologies? Or do trash burners spew dangerous air emissions? The answer may be a surprise. What electricity-generating technology results in net greenhouse gas (GHG) reductions, not just zero new emissions? According to the U.S. Environmental Protection Agency (EPA), it’s not nuclear, not wind, not solar. […]

The U.S. House of Representatives has passed, with bipartisan support, a bill that slackens emissions limits for power plants that burn coal refuse. The Satisfying Energy Needs and Saving the Environment (SENSE) Act passed the House with a 231–183 vote on March 15. However, the White House has said it strongly opposes the bill (H.R. […]

Advances in firing biomass, including bagasse, in Cuban sugarcane operations.

You can’t spell C-S-P without S-P-A-I-N. Though there are now many nations with concentrating solar power (CSP) plants in operation, and nations with larger ones than Spain possesses, it’s difficult to

Despite its apparent environmental benefits and strong government backing, generating power from landfill gas hasn’t gained traction for a variety of reasons in the U.S. Will the Clean Power Plan bolster this “dirty” renewable power source?  For the U.S. Environmental Protection Agency (EPA), the only clean thing about landfills—those engineered dumps that entomb America’s infinite […]

Biomass combustion should not be an approved compliance method under the Clean Power Plant because burning trees is not carbon neutral, both senators from Massachusetts told the Environmental Protection Agency (EPA) on Friday. In a letter to EPA Administrator Gina McCarthy, Sens. Ed Markey (D-Mass.) and Elizabeth Warren (D-Mass) said that treating bioenergy as having […]

Copenhagen could inaugurate, as early as 2017, a new combined heat and power plant that features a roof-wide artificial ski slope open to the public and blasts smoke rings through a 124-meter chimney.  The $611 million Amager Bakke plant is owned by five Danish municipalities and is being built by the Copenhagen-based waste management company Amager […]

Methane emissions are garnering increasing attention because of their potential impact on the climate. Though far less methane is released to the atmosphere than carbon dioxide, methane has 20 to 25 times the
