Carbon Reduction

Carbon Emissions
from Landfills

When waste goes to a landfill, the organics break down and release about half CO2 and half methane. According to the U.S. Environmental Protection Agency, methane is 28-36 times more potent as a greenhouse gas than CO2. Despite efforts to place containment measures and burn the methane in combustion engines on landfills (which still releases CO2), landfills are still the third largest source of methane emissions in the United States (according to 2017 data). Plus landfill gas is filled with other toxins – the EPA has identified 94 organic compounds in it, including toxic chemicals like chloroform and carbon tetrachloride.

Coal Consumption in the Power Sector

Coal remains a major global energy source, making up 27% of the world’s electricity production. In fact, global coal production increased in 2019 by 1.5% (source: BP). Whereas global coal fire power in 2000 stood at 1,057,885 MW, this figure has nearly doubled today, with 2,044,831 MW of operating coal power.

Coal Consumption in the Cement Industry

While the cement industry is transitioning to alternative fuels wherever possible, coal remains a major energy source of the global cement industry. Still in 2018, over 80% of the cement industry’s energy source was fossil fuels. It takes nearly 200kg of coal to produce a metric ton of cement, and more than that is needed to produce just a single cubic meter of cement (typical cement density is 1,440 kg/m3).

How Does Ecogensus Help?

When Ecogensus systems are deployed, they divert waste away from the landfill, where there are nearly equal emissions of CO2 and methane. A single Model EGS-5000L can prevent 20 tons of waste from being landfilled per day, or 7,000 tons per year (based on 350 days/year operation). The resulting Ecogensus fuel can replace coal in power plants, industrial boilers or cement factories. This keeps coal in the ground, preventing the associated CO2 emissions. The carbon emissions from the coal-replacement fuel would have occurred anyway at the landfill, but about half of it would have been in the form of far worse methane. While Ecogensus’ technology can enable near-term, significant greenhouse gas reductions, we remain committed to continuing our work to improve and achieve even better results each day.
