Modular, Flexible, Scalable

Diverting organic wastes from landfills should be an immediate priority putting us on the quickest path to reducing short-lived climate pollutants (SLCP) and facilitating the circular economy

TNRE develops, builds, and operates state-of-the-art organics to renewable energy facilities, including large, regional, high solids anaerobic digestion (HSAD) infrastructure. These facilities reuse and repurpose organic resources diverted from landfills to create beneficial, sustainable products, including biogas, RNG for pipeline injection, and soil-amending compost. TNRE is focused on partnering with communities in California to meet local and state requirements for diverting organic waste from landfills and cutting short-lived climate pollutant (SLCP) emissions.


TNRE believes strongly in the importance and urgency of diverting organics from landfill – avoiding methane emissions and putting organic material to work. We are developing a solution that helps municipalities and waste management companies address changing collection behavior and increased percentage of food material in the organics stream. Developing, building and operating large-scale, regional, high solids anaerobic digestion (AD) facilities, with advanced composting, we can help meet big SLCP-reducing targets and minimize any new potential source of methane emissions.

Holistic solution for processing diverted organic materials


Putting organic streams to beneficial use, TNRE has developed a high solids anaerobic digestion solution, with advanced composting, capable of processing the entirety of the organic material stream. TNRE Organics Renewable Energy Facilities can process and recycle commingled (“mixed”) organic material. What does that mean? Mixed or commingled organic material can be food scraps, grass clippings, or yard trimmings. Plus, our facilities are versatile and can effectively process high rates of food as habits change and collection systems evolve.


Did you know that organics wasted at landfills constitute the largest component of municipal solid waste? When landfilled, those wasted organics result in the emission of super-pollutant methane. We are focused on eliminating these current practices with an efficient and effective circular economy solution, using naturally occurring bacteria to produce biogas, a renewable fuel. With a growing need and rapidly changing market for renewable natural gas (RNG), as well as federal and state procurement requirements, TNRE will have the ability to produce large amounts of RNG for pipeline injection or thermal applications to decarbonize industry, and hard-to-abate sectors, and work to replace fossil-derived gas.

Environmental Benefits and Valuable Products from a 600,000TPY TNRE OREF


We want to change the way waste is collected and disrupt how we think about recycling. By reusing and repurposing organics, diverted from our landfills, TNRE is creating useful, sustainable, beneficial products including a solid soil amendment organic compost. Producing large quantities
of soil-healing compost, TNRE will have the ability to service regional agricultural, farming and landscaping needs. Compost inspires microbes to improve soil structures enabling the soil to hold and transmit water, retain nutrients, leading to improved plant growth, increasing the organic matter in the soil, water holding capacity is improved as well as overall soil health. Recent research shows compost application is a carbon sequestering method plus, TNRE compost will enable a circular economy keeping nutrients in the loop, helping to reduce pesticide usage, and synthetic fertilizers.
