This project is a farm-based anaerobic digester
project that will process the farm’s dairy manure as well as approximately
12,000 tons/yr of off-farm organics. The facility will produce biogas that
will be cleaned and then sold to FortisBC and injected into the existing
natural gas pipeline. A unique aspect of this project is the digestate that
is produced will be further processed on-site to produce a number of
co-products. First the digestate will be solids separated to produce bedding
that is used on the farm. Due to the high level of phosphorus in the soil in
the Delta area, phosphorus will be recovered from the liquid digestate to
create phosphorus rich mulch, which can then be used by area farmers who are
currently importing phosphorus onto their farm for their crops. This process
will leave a liquid digestate with lower phosphorus levels that can be more
easily applied to the surrounding fields at the farm.
A feasibility study for this facility was carried
out in 2010 as part of a study for ARDCorp to determine the feasibility of
biogas projects in British Columbia. Following this study Jerry Keulen, the
owner of the farm, decided to continue to develop the project. The facility
began construction in the spring of 2014 and is operational since early 2015.
CH Four has worked with Western Organics Management and Kloot Construction to
build this complete waste management facility.
CH Four has worked closely with Metro Vancouver to
obtain an Air Permit and to ensure that the facility will be able to manage
any potential odours associated with the project. Part of this was the
development of a Progressive Odour Management Plan for the facility.
