Advantek®’s Terminal
Island Site

The largest carbon removal facility on earth, using the most advanced biosolids management technology anywhere







Municipal Waste Management Through Deep Earth Injection

Located at the Terminal Island Water Reclamation Plant in the City of Los Angeles, California, Advantek’s Terminal Island Renewable Energy site (TIRE) is the world’s first permanent facility injecting organic materials like biosolids and treated sewage sludge. TIRE also injects filtrate brine from the City’s reverse osmosis water recycling processes.

Our facility was developed in partnership with the City of Los Angeles, the US EPA, and the US Department of Energy and commenced injection operations in July, 2008. The site now manages 100% of the biosolids from the City of Los Angeles Terminal Island Plant and about 20% of the residuals output from the Hyperion Treatment Plant.

Municipal Sludge – A Growing Challenge
Each year, millions of tons of sewage sludge and biosolids are generated by municipal sanitation agencies around the world. In the United States and elsewhere, most biosolids are trucked long distances and spread on rural land or, in some cases, pumped into waterways or oceans. For example, in the City of LA, the biosolids which are not injected at our facility are dewatered and hauled nearly 300 miles round trip to be land applied in another county.

Advantek’s patented Deep Earth Digestion / Sequestration technology covers all aspects of a successful project: appropriate geological formation selection, well design, and advanced geophysical monitoring. Using our technology, biosolids can be injected and permanently sequestered within the soft, porous, sand formations in the deep subsurface, around 5,000+ ft below ground. Doing so provides significant environmental benefits, including: eliminating land application and discharges into waterways (and their associated emissions and odors), geologic sequestration of CO2 and CH4 generated by biosolids decomposition, improving environmental justice, eliminating trucking, and providing greater local control.

Moreover the facility has the capacity within its permitted wells to handle up to 100% of the city’s biosolids for the next century, an unprecedented capacity unmatched by any of the city’s other management options.

In 2010, the TIRE project received the National League of Cities (NLC) Award for Municipal Excellence. The award recognizes cities and towns for outstanding programs that improve the quality of life in America’s communities.

Carbon Credits
TIRE permanently sequesters more biomass carbon than any other publicly known facility. Carbon credits from this facility are being marketed by our exclusive partner, Vaulted Deep.
