101 For Low Carbon Fuel Standard
In-state RNG projects, such as this anaerobic digestion facility in South San Francisco, are eligible under the LCFS for either self-use, direct sale as a conventional fuel replacement, or by injecting into a pipeline and demonstrating RNG use as a vehicle fuel.

California’s Low Carbon Fuel Standard, which grew out of the state’s Global Warming Solutions Act, is stimulating markets for biogas, including renewable natural gas.

Deep Dive Into Danish Biogas
Biogas became a political priority in Denmark as a means to control agricultural waste management problems and provide a flexible renewable energy product. (Photo on left, taken at Nature Energy Månsson biogas plant in Brande.) Receiving hall for deep litter (non-liquid manure) at the Midtfyn Biogas Plant (right).

The state of biogas in Denmark has been driven by economies of scale, standardized designs, buy-in from farmers and, not least, strong, bipartisan policy support.

Managing Compost And Mulch Fires
Photos taken from the safety of a vehicle illustrate the level of devastation at the LCEC. High winds at 50 mph spread the Creek Fire through the site, quickly engulfing large equipment.

Planning for proper procedures to prevent fires, and to manage them when they occur, are key components of every facility’s operation protocol.

The Warm Hug Of Compost
In the “heating loop” warmed glycol, from the aeration pad, circulates into the pump house (1) via two variable speed and energy efficient pumps (2). This building houses the heating/cooling exchange system. Here, warmed glycol preheats domestic hot water that is used in the office and is pumped into the adjacent office/shop building. The system features manual valves (3) to switch between the compost-warmed glycol and well-water cooled glycol.

The Dirt Hugger composting facility utilizes heat recovered from active composting to warm its new
office building and mechanics shop.
