Newtrient Comments/Opinions:

Regenis is an experienced EPC Contractor on farm-based anaerobic digestion and nutrient recover systems having served in that capacity on 13 projects across WA, ID, OR and CA with on-going project development continuing across this and other expanded regions while also expanding in scope to include renewable natural gas (RNG) in addition to the combined heat and power (CHP) projects they have done in the past. Regenis will assist a project from cradle to grave putting the team together, grant writing, connecting to tech providers and financiers, assist is permitting, fabrication within our extensive metal fabrication facilities, and will provide service after the installation. They presently provide full service at several installations they have done as well as three other projects.   Regenis has traditionally done projects centered on DVO licensed mixed plug flow anaerobic digesters, but are willing and able to work with other technologies as well. On several projects they have installed and operate various post digestion treatment technologies including screens, DAFs, ammonia stripping, as well as CHP engines, H2S scrubbers, biogas conditioning equipment, pressure lines, and injection points to RNG pipeline. They are also doing projects at urban/rural interface using co-digestion and diverse feeds requiring non-farm placement and other key technologies like depackaging, etc. While their past experience is truly on-farm they are actively marketing to other areas that take advantage of their core expertise and expertise. Nutrient and water management is vital and Regenis is quickly moving towards being a provider of key technology to respond to the need of the dairy industry in these areas and they are becoming much more than an AD company.   Regenis takes an active part in industry outreach beyond their own sales and marketing. They are active in the American Biogas Council and other industry groups, and have shown a commitment to open transparency and moving the industry forward. Newtrient will continue to work with Regenis to further refine the cost and performance information as more information comes in with new commercial dairy installations.
