In California, the Santa Barbara County Department of Public Works, in collaboration with the cities of Santa Barbara, Goleta, Solvang and Buellton, hopes to modify current waste management operations at the Tajiguas Landfill by adding a materials recovery facility (MRF) and dry fermentation anaerobic digestion (AD) facility. The proposed MRF would sort MSW into recyclables, organics and residue and have a design capacity of up to 800 tons per day of MSW or up to ap-

proximately 250,000 tons per year. As much as 90,000 tons per year (290 tons per day) of recyclable material would be recovered and sold for reuse. The adjacent 63,600-square-foot AD facility would be capable of processing up to 73,600 tons of material per year, made up of organics recovered from the MRF as well as other source separated organic wastes brought to the project site. The AD facility would use a dry AD process developed by the German Company BEKON.

Ameresco completes 16-MW LFGTE project in Illinois In late October, Ameresco Inc. announced the completion of a 16-MW landfill gas-to-energy (LFGTE) project at the Orchard Hills Generating Station near Rockford, Illinois. Ameresco contracted the Rockford LFGTE project in July 2014. The engineering,

procurement and construction contract for the project included comprehensive design, engineer-procure, permit and construction services. Ameresco is also operating the project for Hoosier Energy. According to the company, the LFGTE project is the fourth biogas-fueled project the

company is operating for Hoosier Energy. The facility turns landfill gas into electricity. It is powered by six 620 Jenbacher engines and capable of producing enough electricity to power more than 8,000 homes that use 1,200 kWh of electricity per month.
