The document proposes an eco-industrial park at the Port of San Francisco that would include a biodiesel plant and biosolids treatment facilities. The biodiesel plant would be an anchor tenant using feedstock from a rendering plant and water treatment plant. It would supply biodiesel to city and port fleets. The biosolids treatment would move pelletized biosolids by barge instead of trucks to reduce emissions. Adding food waste digesters could produce compost and methane. The eco-industrial park would create jobs and benefits for the community through reduced traffic, noise, pollution and odors.

The Pier 90-94 Backlands site (“Backlands”) -44 acre site located south and upland of Islais Creek, -Within the Port’s 278 acre Pier 80-96 Maritime complex. -Undeveloped former landfill Most of the Pier 90-94 Backlands is designated in the Port's Waterfront Land Use Plan -Surrounded by the Port’s remaining modern cargo terminals at Piers 80, 92, and 94-96 -Currently handle primarily bulk, break bulk and other non-container cargoes -Adjacent to the Port's freight rail facilities.
The potential development ideas for the 44-acre site, -750,000 square-feet of warehousing space, -however studies show this is not economically feasible given the underlying land is on non-engineered landfill -would require extensive piling. -engineering analysis indicated the site would not be cost-effective to erect foundation-supported structures -primarily due to fill characteristics of the site. -Eco-Industrial Park that could include -City-owned Bio-Diesel Manufacturing plant, -new Public Utilities Commission (PUC) Waste Water Treatment/Food Digestion to replace an existing plant -solar power production facilities -relocation of the Department of Public Works (DPW) Asphalt Batch Plant with a new facility, and -concrete and asphalt crushing and recycling. The Eco-Industrial Park development concepts are based on the principles of supportive and compatible uses with maritime businesses, economic development, environmentally sustainable development that provides benefits for the community.
Potential Eco-Industrial Site Plan
Built 1952 and expanded several times since then. Completed in 1982. Handles 80% of city’s wastewater (The other 20% is handled by the Oceanside treatment plant, on the west side of SF) Combined wastewater treatment facility: Stormwater runoff Domestic wastewater Industrial wastewater Wastewater treated in dry weather: 67 mgd Wet season capacity: 250 mgd
What are biosolids?: Ninth stage of wastewater treatment production at SE facility Solids are thickened and mixed with other parts of previous treatments: Sludge Scum Anaerobic bacteria eat solids in digesters to stabilize sludge Byproduct is methane gas Gas is used fuel boilers, which warm digesters Co-generation facility onsite provides 30% of facility’s power needs

Dedicate 14 acres of Backlands for Biosolids Segment of Water Treatment Current facility to be reconstructed (build in the 1950s) Current facility in extremely close to residential neighborhood Backlands site is downwind of the community
Transport solids such as biosolids pellets by barge rather than truck for inland agricultural uses Water transportation much more energy efficient and produces much lower carbon emissions
Reduce odors and emissions (?) by moving to other side of residential development Creates jobs [get numbers]: 9910 program Apprenticeship program Construction jobs Excess methane could be stored rather than flared (?) Transport of biosolids pellets by barge rather than truck reduces traffic and particulate emissions (?) Visual mitigation potential (some treatment sites look nice!)

The new facility could potentially add food waste digesters (which can use scraps from Norcal Waste located nearby, or [GET NAME] facility, located in the backlands property) Food waste can be turned into compost The digesting process produces methane, which can be captured, stored, and burned for energy with a cogeneration facility. (Potential to produce 100% of facility’s energy needs.)
