HDS to Install Anaerobic Digester in New Brunswick, Canada

Anaerobic digestion

Company enters into seven-year agreement with the city of Saint John, New Brunswick.

REW Staff December 7, 2012
HDS International Corp., Providence, R.I., a renewable energy, waste management and eco-sustainability company has announced its wholly-owned Canadian subsidiary HDS Energy & Ecosystems NB Ltd. has entered into a seven-year exclusivity agreement with the city of Saint John, New Brunswick, Canada for the installation of an anaerobic digester waste-to-energy system. 
 
Having identified the city’s Lancaster wastewater treatment facility through more than a year of discussions with the city as an attractive potential location capable of supporting up to 5 Megawatt of electric power, HDS will lead a feasibility study for Lancaster with support from the city. The study will gather information to produce detailed budgetary data, define milestones and optimize the structure and risk/return profile fitting the project’s various constituents. 
 
The envisioned Lancaster digester will draw biosolids and sludge directly from raw wastewater, prior to entry into Lancaster’s treatment lagoon. This biowaste, along with other biodegradable materials, will be processed by the digester, producing biogas, energy and other byproducts that will be marketed and sold to generate revenue. The digester is expected to reduce the city’s operating costs while increasing facility capacity and delivering significant benefits to the environment.
 
The project at Lancaster will incorporate HDS’ carbon dioxide capture and reutilization technologies, unlocking substantial opportunities for value creation incremental to those in classical digestion, says the company. The feasibility study will incorporate the possibility of removing carbon dioxide from pre-combustion biogas, enabling the compression of biogas; controlled-environment algae biomass production in the Lancaster lagoon utilizing wastewater nutrients and recycled carbon dioxide; and supplementing digester biomaterial with algae to boost biogas production.
 
By leading a partnered design, build, operate and maintain project, HDS says it stands to create value for its shareholders through economic participation in the project, which will be anchored by proven digester technologies. 
 
Tassos Recachinas, HDS president and CEO, says, “Today’s announcement represents a pivotal milestone for HDS, and I couldn’t be happier than I am in announcing a partner in Saint John. The potential synergies between HDS’ leading proprietary intellectual property combined with the abundant economic potential of a thriving industrial center, plus the attractive geological and environmental characteristics of Saint John, make for limitless long-term possibilities.” 
 
Under the terms of the agreement, HDS has received exclusive rights to any digester project involving the city’s municipal infrastructure for a period of seven years. The city of Saint John will assist HDS during the study by contributing staff support and through other internal means. The potential system is viewed as being aligned with the city’s planning and sustainability goals, and was executed by the Mayor and Common Clerk following a resolution by Common Council.
 
Graham Huddleston, P.Eng., operations manager of Saint John Water, says, “The idea of converting wastewater treatment byproduct from a substantial operating expense into a source of renewable energy and revenue while improving sustainability is exciting, to say the least. This project has the potential to deliver significant benefits to the environment and the utility ratepayers, and we are anxious to continue working closely with HDS while they lead this feasibility study.”
