Burton Ewert is a Biologist, BS 1996 San Diego State University, with the City of San Diego’s Environmental Services Department.  His continuing education includes a broad array of topics, from gnat catcher and fairy shrimp identification and survey techniques, to Manager of Landfill Operation certification.  He specializes in habitat restoration, with experience in extreme disturbance restoration, including establishing native vegetation and occupied habitat on “yellow fill” soils, experimentation with soil amendments, microsite modification, and control burn techniques.  He has extensive experience in plant propagation, such as greenhouse design, construction, and use, and various planting methods, ranging from container plantings, to broadcast, to hydroseed.  His strong interest in soil microorganisms enhances his current duties managing the composting operation at the Miramar Greenery, which has undergone recent modifications to include two multimillion dollar “aerated static pile” systems.

Session Name: Municipal Composting 2: Addressing Wasted Food through Reduction and Composting

Session Time: Wednesday, January 29, 1:45 to 3:15 PM

Presentation Title: 10 Years in the Making: Case Study describing the City of San Diego Food Waste Composting Project from Pilot to Full Scale and Beyond

Presentation Description: This presentation will discuss the development of the new City of San Diego food waste composting project. We will describe the original pilot implemented in 2009, the CalRecycle grant application process, start-up of the covered aerated static pile technology (CASP). The unique mobile design of the CASP allowed the facility to be sited atop the existing landfill on an unimproved surface using on-floor piping and off-grid power. The mobile CASP solution further allows the City of San Diego the flexibility to move the compost system to an alternate location at the time the landfill space is required and/or to re-purposed the mobile technology into a permanent compost facility solution to expand the capacity and take full advantage of the environmental controls.

Attendees of this presentation will take away an understanding of the challenges and lessons learned during the design, construction and process control benefits achieved for composting food waste using a covered aerated static pile system in the southern California climate.
