Key Staff

Joyce Davis, P.E. (Retired)   President / CEO

Joyce Davis specialized in civil engineering and project management for public works and private development projects with knowledge and understanding from both business and agency perspectives. She has extensive experience in feasibility assessment, planning, design, and construction administration of projects including large commercial and industrial developments, state prisons and other justice system facilities, subdivisions and planned communities, and streets and roadways. She has served as project manager on a variety of projects ranging in cost from under $1 million to over $50 million.

In her capacity as project manager on several large, complex site development projects for the California Department of Corrections, Ms. Davis supervised multi-disciplinary teams including environmental, geotechnical, civil, mechanical and electrical engineers, architects, and land surveyors. The projects ranged in size from 262 to 640 acres and were equivalent to developing a small city from the ground up. She is also experienced in engineering design and calculations, specifications, constructability reviews, and overall quality assurance. 

As Consulting City Engineer for nearly eight years, Ms. Davis’ duties included the review of proposed development projects, as well as the review of construction work for compliance with plans and specifications. She represented the City in meetings with Caltrans, Placer County Transportation Planning Agency and the California Regional Water Quality Control Board. She organized the City’s wastewater improvement program in response to a cease and desist order from the Regional Board. She was also responsible for preparation of government grant proposals, and management and administration of federal and state funded construction projects for the City.

As a consultant to the prime architect, she was the lead civil engineer for the General Purpose Warehouse at the Tracy Army Depot and for the administrative facilities expansion at the Sacramento Regional Wastewater Treatment Plant. She also served in this capacity for the International Security Research Facility at Lawrence Livermore National Laboratory and for the multi-phased expansion of the Department of Veteran Affairs’ (VA) Sacramento Medical Center at Mather Field in Sacramento County. Under separate contract directly with VA, she was responsible for completing surveying, design and preparation of final documents in less than 6 weeks for construction of a new parking lot for the Engineering Complex at the Sacramento Medical Center campus.

Michael Theroux     Vice President

Michael Theroux is a retired California Registered Environmental Health Specialist with more than 35 years of diverse environmental planning and resource management, multiple use permitting and regulatory compliance experience. He has served as coordinator for project development, feasibility analysis, facility siting, permitting, right-of-way acquisition, and utilities research for many large-scale, long term municipal, institutional and industrial projects. He is dedicated to advancing resource recovery through the clean conversion of waste into renewable energy, fuels and bioproducts, and to the commercialization and vertical integration of advanced Conversion Technologies (CTs).

Developing and implementing a diverse, renewable, economical and environmentally sane national energy program at the local and regional levels are specific long-term personal goals. Mr. Theroux maintains a proprietary global database of CTs and ancillary subsystems, along with the industries, agencies, institutions and associations pertinent to this industrial sector. He has launched an industrial advocacy website,, to incite and inform the on-going public/private dialogue focused on conversion of waste for resource recovery.

Mr. Theroux is focused on providing clear guidance through the industrial and regulatory intricacies of waste management, resource recovery and implementation of distributed renewable energy generation. He is proficient in state and federal regulatory pathway interpretation and development, multi-task integration and document preparation through permit application and approval. Long-standing excellent relations with California’s regulatory community provides the inside understanding needed to avoid difficulties and streamline environmental quality compliance. He has developed State and Congressional legislative relations, provided and organized Briefings, and engaged directly in the legislative process advancing key bills related to waste conversion and resource recovery.

Mr. Theroux served for five years as a technical and regulatory specialist on the Alternative Technology Advisory Subcommittee (2003-2008) to the Los Angeles County Integrated Waste Management Task Force, providing guidance throughout Phase I, Phase II and during development and planning of Phase III and IV of the Conversion Technology program for Southern California. Services included global assessment of hundreds of advanced conversion technologies to determine efficacy of systems for ultra-clean, community-scaled conversion of municipal solid waste (especially post-recycling residuals) into energy, fuels and co-products. Mr. Theroux assisted with development of technology assessment criteria, ranking procedures, and methods of comparison; provided regulatory path analysis and guidance; identified and assessed concurrent national and international programs and policies; provided guidance to defining the difference between “conversion” and “incineration”.
