Alex Stege is a Vice President, Senior Project Advisor, and SCS Engineers’ National Expert on Landfill Gas Modeling. He leads SCS’s non-regulatory landfill gas (LFG) recovery modeling services to support LFG-to-Energy and high-Btu methane utilization project development. Over the past 25 years, Mr. Stege developed and refined SCS’s U.S. LFG recovery model that leverages our companywide expertise in LFG collection to assess methane recovery more accurately. This model uses a database of over 1,300 years of measured LFG flows and SCS assessments of collection system performance at over 250 landfills to empirically define LFG model input assumptions. Mr. Stege has prepared domestic and international LFG modeling/due diligence studies for hundreds of landfills in the United States and around the world for the USEPA, World Bank, International Finance Corporation, landfill owners, municipalities, and LFG project developers.
