Biofuels from waste
Since our carbon recycling process occurs in closed tanks and the synthesis gas created by the decomposing waste is converted into biofuels and renewable chemicals, the low intensity/severity Enerkem process (lower temperature, pressure, and energy needs) do not cause combustion. Neither the feedstock nor the synthesis gas are burned. The resulting atmospheric emissions are limited, well below the environmental requirements, and clearly lower than those caused by burning waste, as most of the carbon, is converted into methanol or ethanol instead of carbon dioxide (CO2).
The Enerkem process produces small quantities of inert materials (residues) that can be converted into an aggregate and used as a building material. It is thus possible to utilize nearly all the waste disposed of in the landfill process. The residue from the thermochemical process is approximately 15%. We also use water in our process. The water is treated in accordance with strict standards before it is released.
Enerkem makes the best use of the experience gained through operations at its industrial facilities in Westbury and Edmonton to ensure proper management as well as control of potential nuisances caused by the presence and operations of treatment facilities, independent of their processing capacity.
The analysis and site selection shall take into account existing industrial areas or other surrounding land uses and proximity to populated areas. Enerkem facilities are designed to blend attractively with the surrounding architecture and landscape, minimizing visual impact. Access and egress are also designed to minimize any noise or congestion nuisances caused by vehicles serving our waste-to-biofuel facilities.
Moreover, Enerkem’s process equipment is selected to meet noise emission standards that promote the health and safety of the employees and the surrounding areas. From the tipping floor to processed material (Refuse-Derived Feedstock) storage, Enerkem’s facilities are all indoors and/or in enclosed conveyors. The buildings all have negative pressure as well as filters to prevent any odor issues. The rest of the process is in enclosed vessels that do not release odors or emissions.
