Leadership Team

Chief Development Officer

Shawn Kreloff, Chief Executive Officer


Mr. Kreloff has a 30-year history of successful entrepreneurial ventures and investments. Throughout his career he has participated in the founding, operating, financing and advisory of over 25 different companies.

Bioenergy DevCo (BDC) began as a research project for Kreloff. Through his research, he quickly discovered the far-reaching benefits of anaerobic digestion technology including environmental sustainability, the creation of renewable energy, and excellent plant economics. Kreloff also recognized the urgent need for this technology to help tackle our planet's growing organic waste problem. Anaerobic digestion's natural microbial process is a truly sustainable solution to waste management yielding healthier and cleaner air, water and soil while simultaneously creating renewable energy and organic fertilizer.

Kreloff's investment thesis for BDC is to marry BTS's proven anaerobic digestion technology with plant financing, engineering, project development, and to guarantee energy yields and plant performance. The last part of the thesis is to bring this solution to the United States and the rest of the world.

Peter Ettinger, Chief Development Officer


Mr. Ettinger is focused on the complex chessboard that makes up the business of anaerobic digestion centered on corporate growth, product development and the forming of innovative partnerships. From municipalities and large food companies searching for solutions to combat incineration and landfill use, to energy and utility companies looking for sustainable sources of truly renewable natural gas, Ettinger ensures that BDC meets the financial, operational and sustainable solutions to the challenges presented by this diverse group. Whether it be business development planning and implementation or the high-level contacts needed to move projects forward, his success has been centered around first defining the vision and then surrounding yourself with really smart people. A believer in “doing well, by doing good”, Ettinger started out in the field committed to finding a solution to the issues surrounding healthy soils along the Chesapeake and found digestate from the anaerobic digestion process fit the bill. His insight and direction on what it takes to transition an idea from the bench to the marketplace has been credited with sales, operational growth, as well as helping raise millions in the venture and investment markets.
