WM unveils LEED Gold organics processing facility
Waste Management of Alameda County (WMAC)
has unveiled its $11 million, state-of-the-art LEED Gold Organics
Processing and Transfer Facility at the Davis Street Resource
Recovery Complex. Only the third Leadership in Energy & Environmental
Design (LEED) Gold building in San Leandro, it is the first industrial
building designed to Gold standard in the city.
Among the building’s distinguishing features are:
- State-of-the-art biofilter to eliminate odor;
- High-speed rollup doors to contain odor and prevent bird
- Daylighting via translucent panels and solar tubes;
- Mechanically stabilized embankment walls built with 100
percent recycled aggregate;
- Ninety-five percent of construction waste recycled;
- Forty percent of building materials sourced locally; and
- Twenty percent of building materials from recycled sources.
In addition, local contractors provided the majority of construction
services and 92 percent were union jobs.
The 34,967 sq. ft. building includes 1,127 sq. ft. of office
space. The balance is dedicated to the processing and transfer
of 150,000 tons of yard trimmings and food scraps annually. Residential
organics are sent to WMAC’s Organics Material Review Institute
(OMRI)-listed composting facility in Marin County. Excess materials
are sent to third-party composters and in the case of nearly
500 tons of Christmas trees to biofuel facilities.
A prototype natural gas collection vehicle, currently being tested
in the City of Oakland, was on hand to inaugurate the building.
Powered with biofuel made from landfill gas at the Altamont Landfill
in Livermore, the truck drove into the new facility following
the ribbon-cutting ceremony.
Celebrants included representatives from Alameda County Board
of Supervisors, City of San Leandro, the Oro Loma and Castro
Valley sanitary districts and many others. They toured the new
building as well as the $1.5 million Public Area Materials Recovery
Facility (PAM) that opened last month and created eight new green
The PAM is designed to process 60,000 tons of construction and
demolition material per year, diverting recyclables from landfills.
Clean construction lumber is sent to WMAC’s mulch facility in
Fremont. There the wood is ground into mulch for gardening. It
is part of the closed-loop approach of WM EarthCare, a new landscape
product line of locally sourced, 100 percent recycled compost
and mulch available at WMAC’s seven Bay Area facilities.
