Converting paper waste to biogas
Project 1 – Catalyst Paper Waste Activated Sludge (“WAS”) to Biogas Production
Project 2 – Catalyst Paper WAS to Biogas Production, Closed Loop
In 2010, BCBN provided Paradigm Environmental Technologies and partner firm, Elemental Energy, with $1.8 Million of the $6.6 Million needed to develop and demonstrate its wastewater treatment technology at Catalyst Paper Corporation’s pulp and paper mill in Crofton, BC.
By testing the technology in a self-contained system at 1% the size of full-scale implementation, Paradigm’s performance data proved the technology’s three main benefits:
- The “digestion” time needed to process waste was greatly reduced, thus increasing throughput which dramatically reduces operating and capital costs;
- By efficiently liquefying waste-activated sludge, MicroSludge® reduced the volume of bio-solids that needed to be transported offsite for disposal; and
- A much higher percentage of those bio-solids were converted to methane gas, which can be used as energy.
With paybacks in less than three years at full-scale, this technology could dramatically increase the capacity and sustainability of existing wastewater treatment systems in pulp and paper and municipal sectors.
