No matter how sophisticated their waste management programs are, developed countries still face the challenge of how to keep residual municipal solid waste (MSW) out of landfill. Some high-income countries have managed to keep up to 90% of waste out of landfill. But overall the diversion rate for high-income countries is about 60%.
The residual MSW that winds up in landfill includes a high concentration of wet organics. When organic material in MSW decomposes, it creates methane, a greenhouse gas and a significant contributor to global warming. At the recent COP26 summit, more than 100 countries pledged to cut methane emissions by 30% by 2030 compared to 2020 levels.
In May 2021, the United Nations Environment Program (UNEP) released “Global Methane Assessment: Benefits and Costs of Mitigating Methane Emissions.” In this report, UNEP stressed the importance of reducing methane emissions to slow the rate of global warming. Methane emissions from the waste sector account for about 20% of global methane emissions from human activities. The report concluded that in Europe, eliminating MSW from landfill holds the greatest potential for reducing methane emissions.
Dryclone® DSRF-WTE Plants are the solution
With Dryclone® DSRF-WTE (Dryclone Solid Recovered Fuel Waste-to-Energy) Plants, there is finally a way to divert 100% of MSW from landfill.
- Divert 100% of MSW from landfill
- Produce baseload-quality renewable electricity
- Dramatically reduce methane emissions.
Dryclone DSRF-WTE Plants can accept the entire residual MSW stream. The result is the dramatic reduction of methane emissions from landfill. Dryclone DSRF-WTE Plants can also accept residual commercial and industrial (C&I) waste, hazardous waste, medical waste, tires, and some waste from the oil industry.
How it works
Dryclone DSRF-WTE Plants feature a unique combination of leading technologies:
- The plants are self-powered. The balance of the electricity produced can be sold to the grid.
- Dryclone DSRF-WTE Plants produce Dryclone Solid Recovered Fuel (DSRF). DSRF is unique because it contains the entire MSW stream, including even the wettest organics.
- The unique component of the Dryclone DSRF-WTE Plant is the Dryclone itself. With its aerodynamic pulverizing action, it removes surface and internal moisture from even the wettest residual waste, including organics.
- Dryclone’s unique capabilities ensure that DSRF is optimized for consistent energy recovery in the pyrolysis stage.
- The pyrolysis stage produces syngas and char, with zero emissions.
- The thermal oxidizer stage eliminates pollutants.
- The heat produced from the syngas in the thermal oxidizer is used to generate steam, powering turbine gensets that generate baseload-quality power.
