Utah’s first anaerobic digester for food waste will produce enough renewable natural gas to power 15,000 homes. DMT Clear Gas Solutions is an integral part of this project by providing the upgrading technology for the biogas.

Approximately one-third of the food produced for human consumption annually gets lost or wasted. The Wasatch Resource Recovery project will become an advanced food waste digestion facility that will process approximately 180,000 tons of food waste per year that will be diverted from landfills. By processing the food waste on this progressive resource recovery site, the life of the local landfills will be extended. Greenhouse gases will be reduced by an equivalent of over 75,000 cars. Not only the methane will be used as natural gas but also part of the CO2 will be reused to grow algae. The Wasatch Resource Recovery site in North Salt Lake, UT has selected DMT Clear Gas Solution’s upgrading technology for their recovery site. Read full article


Biosolids are becoming increasingly economical valuable and are no longer a waste product but a valuable resource. But how to get the most value out of your project?

Increasing the value of your biosolids is dependent on the overall design of the plant and how to integrate the latest technology with RIN revenues, class A+ land application and nutrient recovery.
The digester is the heart of the system. But like a human body, the organs around the hearth make it pump the most efficient. Starting with high pressure thermal sludge hydrolyses to effectively get the organics available for the bacteria. This will increase the amount of organics that is digested by about 30%, decreasing digestate and increasing biogas production. But it also increases the digestion process, reducing the retention time so a smaller digester is needed (or more solids can be processed). Biogas depressurization and upgrading makes the best business case. By using a combined chemical scrubber with biological regeneration, the H2S can be converted to elemental sulfur and sold as fertilizer. Thanks to the thermal hydrolysis the digested can be used for class A fertilizer. Nutrients can be recovered to Struvite; ammonium sulfate and/or mixed with the Sulfur. All the technologies are readily available and the economical incentives are growing.

DMT is here to help you with the Clear and Prosperous future.
