SAN ANTONIO, TX — Synthica Energy, a developer of anaerobic digestion facilities that convert organic waste into renewable natural gas (RNG), has selected Archer Western Construction (a subsidiary of The Walsh Group) as its partner for development of Synthica’s new facility in San Antonio, Texas. Archer Western has been issued limited Notice to Proceed with construction of the facility which, when completed, will have capacity to process up to 250,000 tons of industrial organic waste per year, diverting it from landfills and turning it into renewable energy. Synthica conducted a Request for Proposals process in Q1 of 2024 for selection of qualified construction partners to join the team during the detailed design phase of the San Antonio project. Archer Western was initially selected to provide preliminary services support, including design and constructability review, cost estimating, value engineering, evaluation of alternative construction means and methods, procurement support, and construction schedule optimization. “Throughout the pre-construction phase, Archer Western demonstrated capabilities and know-how that allowed Synthica to make some critical design decisions to maximize the value of the project,” said Craig Thompson, Technical Project Director for Synthica Energy. “Their exceptional experience in the water/wastewater sector and superior foothold in the San Antonio market, made them the ideal partner for us on this project." Synthica’s San Antonio facility will process organic waste in an advanced anaerobic digestion treatment process, generating biogas that will be further upgraded into RNG for injection into a nearby pipeline, displacing the use of fossil fuels. “Archer Western Construction is excited to partner with Synthica Energy on their San Antonio organic waste to energy facility,” said Jeff Polak, Vice President, Archer Western Construction Water Division. “We look forward to working together to deliver a cost-effective solution to keep organic waste from the local landfill and provide clean, renewable energy."
