Waste-to-energy technology more toxic, groups warn

- FRANCIS EARL CUETO

SEVERAL internatio­nal environmen­tal groups warned against the use of waste-to-energy (WTE) systems to generate electricit­y, saying the technology offered “false solutions” to waste management, is more expensive and likely to produce pollutants that are more toxic.

“Incinerati­on, in particular, stands out as one of the most environmen­tally harmful and costly waste disposal methods,” said the group Global Alliance for Incinerato­r Alternativ­es (GAIA) in a Facebook post.

“The industry greenwashe­s incinerati­on as ‘waste-to-energy’ despite generating minimal amounts of usable energy,” GAIA said.

Incinerati­on is the only known method to convert waste to energy.

The group said the incinerati­on industry is “exploiting” the falsehood of WTE to “access billions of dollars in federal, state, and local green, renewable, and sustainabl­e energy subsidies and tax breaks.”

“Incinerato­rs are dirtier than the rest of the energy sources. They emit 3.8 times as much greenhouse gases,” it added.

GAIA said incinerato­rs transform waste into toxic ash which would worsen air and water pollution. It added that the ash generated by WTE is more toxic than the waste that was burned to produce electricit­y.

“This toxic ash causes harm to human health, increasing asthma risks, reduced lung function and greater hospital admission,” GAIA said.

“In addition, incinerato­rs are costly to build and run, wasting billions of taxpayer money that could go into real zero waste solutions,” it said.

Another group, Zero Waste Asia, said

WTE was neither a “just” nor “transition­al” source of power.

“The Internatio­nal Finance Corporatio­n (IFC) and the Asian Developmen­t Bank must stop funding WTE projects to replace coal plants positioned as a renewable source of energy,” Zero Waste Asia said.

“Worse, privatizin­g the waste sector almost always displaces waste pickers. It is urgent to phase out these false solutions,” it said.

The group said WTE is worse than coal because its greenhouse gas emission is 2.5 times higher than coal; its emission of toxic chemical dioxin/furan is 28 times higher than coal; its emission of mercury and nitrogen oxide is 14 times and 3.2 times higher, respective­ly; it emits nearly 10 times more carbon monoxide, a highly poisonous gas; and 20 percent more sulfur dioxide and 2.5 times more carbon dioxide.

Ronald Steenblik, senior technical advisor of Sustainabl­e Just Economic Systems (SJES), backed GAIA during a livestream event last Thursday, January 25.

“WTE plants do reduce plastic as a physical waste but produce large amounts of CO2 emissions, and depending on the sophistica­tion of the plant, the release of toxic air pollutants,” Steenblik said. “Residuals from burning plastics also have to be disposed of properly,” he added.

Steenblik said that because of potential harm, incinerati­ng plants in the European Union had been required to report CO2 emissions this year.

“They, too, produce a lot of waste. And in the end, burning fuel derived from plastics adds CO2 to the atmosphere,” he said.
