Composting Facility Maintenance
Infrared thermography uses a specialty camera (below) that displays and captures images color-coded by temperature (top, right). Users can quickly identify high temperatures on rotating equipment such as a bearing (bottom, right).

Composting facilities can develop a maintenance plan to ensure that the right resources are being used at the right time, minimizing surprises.

Smithfield Foods Goes Big On Biogas
Preconditioned biogas from the farms is routed to Optima KV’s central gas clean-up facility (above) on Smithfield Foods’ property. The cleaned biomethane is pressurized to pipeline standards and sold to Duke Energy.

A commitment to anaerobic digestion on 90 percent of its hog finishing farms in 3 states was followed by formation of a joint venture with Dominion Energy, called Align Renewable Natural Gas.

Anaerobic Digestion Of Aquaculture Organics
Salmon waste (top, right) is fed into an ensiling tank (center) equipped with an 18.5 kW stainless steel long shaft chopper pump (bottom, right). The “smooth purée” is then discharged into the pasteurizer.

Scottish waste authority recently installed a pasteurization system to enable it to accept salmon waste — and meet the UK’s Animal By-Product regulations.

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

Florida Organics Recycler Expands Exponentially
Sarasota-based 1 Stop Landscape Supply & Yard Waste Recycling Facility processes about 70,000 tons/year of yard trimmings, land clearing debris and pallets.

Acquisition of a 10-acre yard trimmings operation in 2004 laid the groundwork for a 100-acre facility that manufactures compost, mulch, soil blends and recycled concrete products.

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.
