General Systems Research (GSR)

About the Company:

GSR started at the turn of this century, when its co-founders were developing a new approach to the general systems theory for complex systems that cannot be easily modeled. After a decade, they extended their passion for general systems and firsthand experience with Chesapeake Bay and Lake Champlain health issues into creating value from waste nutrient inflows, and in 2008 they created the General Systems Research (GSR) company. GSR grew with stakeholder partnerships and industry relationships, and in 2014 became ‘GSR Solutions’ – a company with a vision of transforming agricultural and industrial waste processing using innovative systems to capture waste stream nutrients, create high value products, reduce operating costs, and enable growth by addressing waste management subject to regulatory discharge standards.

About the Solution:

GSR's patent-pending, scalable, bolt-on platform changes the waste nutrient management game.  It converts the growing problem of excessive nutrients into an enormous opportunity by generating new revenue sources from clean, organic streams of recovered materials and saving on treatment costs - nationwide and worldwide. GSR's process combines cutting edge technological advances with mass production of biomass grown on excess nutrients to transform waste into valued products and services for fast growing markets such as waste remediation, water reclamation, fertilizer, feed and fuel.

GSR’s technologies are designed to benefit their partners (dairy farms, food and beverage industries, municipalities) managing wastes with or without anaerobic digesters. The technology for digesters is efficient in recovering nitrogen and phosphorus from the digested effluent, further reducing the Biochemical Oxygen Demand (BOD) of anaerobically treated effluent, enabling the production of valued byproducts including soil amendments, fertilizer, and fuel. This system enhances the economic and environmental performance of digesters as demonstrated in GSR’s EPA supported project that utilized dairy and industrial effluents. An alternative system designed to recover nutrients without going through the anaerobic digestion process can address the needs of hosting sites that have no on-site digesters. Among several projects organized, managed, and completed by GSR, a recently completed project supported by the USDA at a dairy farm has culminated into a new project involving few other farms further supported by the USDA.

Newtrient Comments/Opinions:

GSR Solutions began its work with the dairy industry through a R&D project to grow algae using cow manure nutrients to make aviation grade biodiesel as part of the "Farm to Fly" project funded by DOE. They have expanded the offering of their system to include two specific processes and their goal is to support the dairy industry in addressing their nutrient recovery needs. Newtrient is not currently aware of any active systems associated with this project. GSR has not been evaluated using Newtrient's 9-point scoring process because this solution is not yet commercially available.
