Technology Combo Yields RNG And Compost
Leachate from the dry AD tunnels is collected and put into the wet AD tank along with any liquid organics that Surrey Biofuel receives.

The Surrey Biofuel facility employs wet and dry anaerobic digestion, and tunnel composting, to manage municipal and commercial organics.

Moving The Biogas Needle In North Carolina
A microgrid pilot project was installed at Butler Farms, a hog producer with an anaerobic digester. Components include a battery system and controller (below), solar panels, a diesel generator and a biogas-powered generator.

Could this state serve as a national model for how to catalyze the biogas economy?

Pipeline Injection Of Biomethane In California
Biogas is conditioned at the CR&R anaerobic digestion facility in Perris (CA) and then transported about 1.4 miles via a high-pressure steel pipe (shown here) to the SoCalGas interconnection “point of receipt” (see next photo).

Funds are available for project developers, and low carbon fuel market incentives are attractive. Will this lead to more RNG being injected into California’s gas pipelines?

Reducing Wasted Food In Tennessee
The Nashville Food Project (TNFP) brings people together to “grow, cook and share nourishing food, with the goals of cultivating community and alleviating hunger.” Delvin Farms shown donating strawberries to the TNFP.

About 15 percent of Tennessee households are food insecure, and almost 1.2 million tons of food are landfilled annually. The state is moving quickly to address both realities. Part I

Food Waste To Renewable Natural Gas
Solid food waste feedstocks will be depackaged, decontaminated and slurried to 10 to 14 percent solids in the Re:Sep system (example installation above). The unit includes a vertical paddle mill with 2 sizes of screen mesh.

Groundbreaking held in June for 180,000 tons/year anaerobic digester that will generate up to 3,000 dekatherms/day of renewable natural gas.

Food Waste Collection Truck Innovations
The ROTO-PAC® marketed by New Way has a retractable arm that can extend 12-feet (left) and a rotating auger mounted in the collection hopper (inset) that mixes and shreds organics, freeing up space in the truck body.

Manufacturers are responding to the increased demand for vehicles that can service commercial and residential source separated organics collection.

Phosphorus And Compost Use Dynamics
Excess amounts of phosphate can cause algae blooms to occur. Inorganic forms of phosphate pose the greatest risk to water quality.

Organic forms of phosphorus, such as biosolids and compost products, contain low to very low levels of water extractable phosphorus, but increasingly are regulated like inorganic P sources.
