Advanced Anaerobic Digestion

The Planets Most Advanced & Efficient Waste-to-Energy System

Advanced Anaerobic Digestion

The Planets Most Advanced & Efficient Waste-to-Energy System

Our Advanced System

Our highly efficient Tribrid-Bioreactor™design and superior end-to-end process is uniquely designed to treat organic byproducts and wastewater from your food or beverage plant without trucking or burdening public waste treatment resources, this creates a positive environmental impact and substantial cost savings. ­Green Energy Resource waste-to-energy plants are built on our robust, uniquely patented, technology featuring self-buffering operation, a small physical footprint and the separation of hydraulic and organic treatment zones. The process cleans the incoming feedstocks by converting the organics, in the wastewater and other streams, into biogas – a renewable fuel.

Hasper Kuno

Technical Sales Executive

It wasn’t long after returning from a six-month stint in Denmark, working with renewable energy systems, that Hasper found himself in South Burlington, Vermont, helping PurposeEnergy with their revolutionary anaerobic digestion technology. Fast forward ten years and Hasper has become an instrumental part of the team at PurposeEnergy. After building an impressive skill set as PurposeEnergy’s Chief Operator and Operations Manager in Vermont – including the GMWEA 2017 Industrial Wastewater Operator of the Year Award – Hasper has most recently transitioned to business development and feedstock origination. His hands-on experience and unique technical understanding of industrial systems allows Hasper to bring value in assisting new partners, process design, startup, commercialization, and the trouble shooting of treatment systems.

 

A graduate of St. Lawrence University in Upstate New York, Hasper enjoys the great outdoors, playing ice hockey year-round, and spending time with family and friends.

Sean O’Neill

Vice President, Development & Offtake

In the energy world, Sean O’Neill has covered a lot of territory.  He designed and ran energy efficiency programs for large residential and commercial buildings in New York City, closed some of the most innovative financings for energy system retrofits in both public and private property, led development of cogeneration plants and solar projects, and developed large greenhouses in an effort to reduce emissions from agriculture.  Along the way he has advised city and state governments, universities, and leading environmental non-profits.  On a pro bono basis, he helps bring solar power to public and private schools by turning conventional lenders into investors.

When he is not developing energy projects, O’Neill plays a leading role in creating policies that promote a cleaner planet.  He founded the Investor Confidence Project, now part of the US Green Buildings Council, and co-founded the Green Lease Forum with the Natural Resources Defense Council.  He lives on a small farm in Massachusetts with his horse whisperer wife, sundry animals and too many chores.

Todd Hasselbeck

VICE PRESIDENT, WORLDWIDE SALES

With a decade of experience converting food byproducts to energy, Todd had led the company’s acquisition of new projects from its first system to our current nationwide footprint. Prior to that, he spent 2 years in Mozambique’s Gorongosa National Park leading the park’s restoration for a US based NGO. He was selected as a Clean Energy Fellow by the New England Clean Energy Council. Prior to his work in the renewable energy industry, Todd helped to build a string of early-stage companies in the communications industry including; Common Voices, Summa Four (merged with Cisco Systems) and Boston Technology.

A graduate of Cornell University, Todd is at the helm of PurposeEnergy’s worldwide sales organization (did we mention he has built several worldwide sales organizations in the Americas, Africa, Asia and Europe?) His is focused on identifying prospective feedstock partners across the food and beverage industry, and managing the PurposeEnergy sales team.
