Abbotsford, BC – December 14th, 2018 Earlier this year Trident had an opportunity to work with the BioCycle Magazine on a story titled “Recovering Nutrients In Digested Dairy Manure”. Author Peter Gorrie connected with nutrient recovery experts to share their perspective on technology, the future of dairy farming and to provide insight in existing nutrient recovery installations across North America.
The agricultural landscape has changed drastically over the past few years. The U.S. dairy industry is currently going through a serious consolidation process. The dynamics created by global markets, changing consumer behaviour and environmental regulations add additional pressure. The concept of “planetary boundaries”, established by a global group of environmental researchers, makes clear how important the environmental aspect is.

The management of Phosphorus and Nitrogen is identified as high risk area that is currently beyond the zone of uncertainty. Source http://science.sciencemag.org/
This is where programs like the EPA’s Nutrient Recycling Challenge or several state and provincial initiatives come into effect, to stimulate technological advancements that offer solutions for better nutrient management for raw or digested dairy manure. Trident continues to work with different government groups to actively drive and improve solutions to the problem.
Five years ago Trident Processes (back then operating as KPD Consulting) presented its nutrient recovery technology, and shortly after installed the first fully automated nutrient recovery system on a dairy farm in North America. Over the years it became clear how big of a step this really was for the entire dairy industry. To this day, the partnership with 350 cow dairy SeaBreeze Farms in Delta BC, run by the Keulen family, is an impressive example of how a small group of dedicated people set out to pioneer a solution that addresses a global issue.
Prairie’s Edge Dairy in Fair Oaks, IN is the second installation site that the author describes in his article. Although a much larger operation with many different business divisions, Prairie’s Edge also shares similarities with Seabreeze. Both have invested into anaerobic digester and nutrient recovery technologies for digested dairy manure, and are committed towards zero waste agriculture. Much of their waste streams is processed into valuable commodities that are reused.
