Phosphorus Innovation Challenge

Thank you for your interest in the Phosphorus Innovation Challenge!   

Six Proposals Awarded Funding for Stage Two of VPIC:

Recipients of Stage Two Funding through the Vermont Phosphorus Innovation Challenge awarded by Governor Phil Scott.


DVO, Inc. and University of Vermont (UVM) – Chilton, WI – 45,000.00

Thirteen anerobic digester vessels situated statewide will be utilized with enhancements for solids control using Dissolved Air Floatation (DAF) processes and will develop a ‘p-cake’ product that is high in phosphorus for potential nationwide resale that will have a verified and significant value to agriculture.

Rock Dust Local, LLC – Bridport, VT – $25,000.00

Manufacture, apply, and study mineral and mineralized bio-carbon soil amendments (aka Biochar) deployed in the field to manage solution reactive phosphorus (SRP) and nitrogen loss through broadcast field applications, animal bedding admixtures and in-situ filtration media.

Green State Biochar – Barton, VT – $30,000.00

Use of local renewable organic waste materials that are processed in an innovative machine developed in Vermont as a prototype pyrolysis machine that produces a sequestered carbon product called Biochar. This Phosphorus Capture System utilizes this Biochar to act as a filter that efficiently captures the majority of the phosphorus, while producing valuable soil amendment/fertilizer products for local reuse.

Agrilab Technologies Inc. – Enosburg Falls, VT – $50,000.00

Use of a combination of existing phosphorus (P) recovery technologies, composting and drying equipment, and associated best management practices to demonstrate the technical feasibility of stabilizing and adding value to recovered “p-cake” and similar materials.

Agrilab Technologies uses composting and energy captured from the decomposition process to dry and stabilize phosphorus products

Digested Organics – Ann Arbor, MI – $45,000.00

Use ultrafiltration system on a Vermont dairy farm to remove most of the present phosphorus, suspended solids and pathogens in liquid manure, producing a transparent liquid ideal for field application, known as “UF Permeate” (a.k.a. “tea-water”) and a concentrated fertilizer that is readily transportable, known as “UF Concentrate.”

Village of Essex Junction, Chittenden County Solid Waste District and UVM – Essex Junction, VT – $45,000.00

Use of proprietary pipe descaling technology (PDT) to effectively remove phosphorus in Vermont sized wastewater applications. The technology uses an induced electric field of variable amplitude and frequency that can promote precipitation of crystalline minerals (struvite) without the dangerous and damaging adhesion to pipes, pumps or in tanks. The PDT coupled with electric-filtration cell will be employed to enhance phosphorus capture.

Using this innovative method of identifying solutions to problems or challenges, we hope to identify one or more technologies that could help mitigate the impact of phosphorus in our watershed by ensuring that the right amount of phosphorus is applied to the soil at the right time and in the right place, which will in turn minimize losses to our rivers, lakes, ponds and streams.
