Numbers Game: Plant Pollution And Zero Liquid Discharge

Numbers Game Plant Pollution And Zero Liquid DischargePower requires water—whether generated through coal-fired or biomass plants, or consumed by manufacturing facilities. Cooling towers are a prime example—in many cases they utilize more than 90 percent of a plant’s water supply. And despite best efforts, the resulting “blowdown” is often dumped after three or four cycles, creating both efficiency and pollution problems. As noted by Water World, however, the rise of effective Zero Liquid Discharge (ZLD) technologies may now make it possible to create a closed system, reduce costs and ultimately improve environmental conditions.

Coal and The Cold Shoulder—UK Considers Closures

Coal and The Cold Shoulder—UK Considers ClosuresPower generation is a hot topic. Renewable energy sources like solar and wind power have grabbed public attention, while governments look for ways to minimize the environmental impact of traditional fossil fuels such as oil and natural gas. In the U.K., there’s talk of closing all coal-fired plants by 2023 in an effort to curb greenhouse emissions, while on American soil some coal plants struggle to deliver their power quota.

New Report Suggests Serious Water Worries as States Strike Back at EPA Rule

New Report Suggests Serious Water Worries as States Strike Back at EPA RuleHow safe is American water? The debate has been raging for years. The Environmental Protection Agency (EPA) says businesses aren’t doing enough to safeguard both small and large waterways, while companies and state lawmakers alike claim that the agency is overstepping its bounds. As noted by EP Online, a new report now argues that EPA numbers about water pollution are serious underestimates, even as multiple states line up to challenge the new Clean Water Rule. Bottom line? This is a murky situation at best.

Obama’s Clean Power Plan: Problem or Potential?

Obama's Clean Power Plan Problem or PotentialPresident Obama hasn’t made many friends with the announcement of his Clean Power Plan—power producers, Republican opposition leaders, and even typically supportive Democrats have spoken out against the proposed changes.

The plan seems simple enough: Reduction of air pollution from currently operating plants, significant limitations on any new plant emissions and state-by-state reduction goals designed to slash carbon dioxide emissions by 32 percent by 2030. But with all the conflict over Obama’s new plan it’s time to clear the air: Are power plants staring down the barrel of more problems or does this represent big potential?

Serial Soot? Power Producers Under Scrutiny Worldwide

Serial Soot? Power Producers Under Scrutiny WorldwideSoot ranks just behind CO2 when it comes to potential climate change culprits, but may also be responsible for several other ills—a recent study pegs it as the primary driver of glacier melt in Tibet, while residents of a Canadian town are finding ways to manage a veritable “soot storm”. Power providers are now under scrutiny across the globe to manage soot emissions and control this combustion byproduct, but can they get a handle on serial soot production?
