What We Do

Cogen Landfill

Old closed landfill site owned by LA County Department of Public Works. Biogas designed and permitted an activated carbon treatment system to capture volatile organic compounds of the landfill gas generated at this site. Biogas provided construction support and commissioned the Site and performed O&M of the wellfield and carbon treatment system upon completion.

Ventura Regional Sanitation District

Biogas has been providing ongoing engineering support to the VRSD landfill sites (active and closed) since 2016. At these facilities Biogas has:

Designed and installed condensate injection system to destroy the condensate in the existing flare
Landfill gas Hydrogen sulfide removal system design
Landfill gas wellfield expansion
LFG collection system header design
LFG ultra-low NOx flare design

Burbank Landfill

Biogas was hired to replace main LFG collection piping which was destroyed in wildfire. Biogas replaced the section of the main header damaged and restarted the LFG collection system upon completion. Since 2018, Biogas has redesigned and replaced section of headers, installed additional wells and provided support for improvements of the LFG collection system.

Lakeside Dairy Cluster

Biogas designed 30 miles of raw biogas collection pipeline to collect compressed raw biogas from various dairies in the cluster. Biogas also designed centralized dairy digester gas upgrading facility which received the gas from the dairies in the cluster and upgraded it to meet So Cal gas pipeline specifications.

Merced Dairy Cluster

Biogas designed 40 miles of raw biogas collection pipeline to collect compressed raw biogas from various dairies in the cluster. Biogas also designed centralized dairy digester gas upgrading facility which received the gas from the dairies in the cluster and upgraded it to meet So Cal gas pipeline specifications.

Keys Dairy Cluster

Biogas designed 35 miles of raw biogas collection pipeline to collect compressed raw biogas from various dairies in the cluster. Biogas designed and supplied raw biogas compression and dehydration skids at several dairy facilities. Biogas also designed a centralized dairy digester gas upgrading facility which received the gas from the dairies in the cluster and upgraded it to meet PG&E gas pipeline specifications.

VVWRA wastewater

Design and management (while working for Anaergia) of 1.6 MW (two 800 kW MWM IC engines) power generation facility using DG at VVWRA.

San Ramon Wastewater Treatment

DSRSD wastewater treatment plant management asked Biogas to evaluate the existing digester treatment and utilization equipment at their facility processing approximately 200 scfm of DG. Currently, the DG is being used in the IC engines to generate electricity. DSRSD is planning on accepting food waste which will produce additional DG.

EBMUD, Oakland, CA

Prepared engineering design for the processing of 60,000 tons/year of organic waste at the EBMUD waste water treatment plant. Harvest Power Inc. was developing the site to process the organic waste and digest the waste into the EBMUD digesters and utilize the digester gas to make compressed natural gas (CNG) to fuel the vehicles. Prepared engineering design drawings and managed the project.

DRSD

Cogen Carbon System

The Cogen landfill is an old closed landfill, and a portion of the site is owned by the LA County DPW. Prepared design for an LFG collection and treatment system for County owned portion. Prepared LFG design drawings and assisted client with a Mitigated Negative Declaration (MND) process. Designed LFG migration monitoring probes to monitor offsite LFG migration, coordinated work with the client and addressed Local Enforcement Agency (LEA) comments.
