GSR helps farms, food and beverage operations, industrial facilities, and other nutrient-generating operations manage excess nutrients more effectively. Our nutrient recovery solutions are designed to reduce waste burdens, support water-quality goals, and create useful product pathways from nutrient-rich residuals.
Agricultural Farm Operation

Creameries, Breweries, & Distilleries
Food & Beverage
GSR helps electricity or RNG generating anaerobic digester operators manage excess nutrients in digestate while creating additional value from low- or no-value residual streams. Our platform is designed to support farm, food, industrial, and municipal digester settings seeking stronger water outcomes, improved resource recovery, and better project economics.

Industrial Digesters
Agricultural Digesters
Municipal Digesters
GSR’s nutrient recovery solutions are designed for nutrient-rich runoff and wastewater streams that create environmental, operational, and compliance challenges. We help recover excess nutrients from farm, industrial, and other organic wastewaters while supporting cleaner water and practical value recovery.

GSR's process converts excessive waste nutrients into certified organic fertilizers , agricultural biologicals , and other soil amendments for food producers and gardeners. Our patented technology produces balanced, nutrient-rich fertilizers containing nitrogen (N), phosphorus (P), and potassium (K) in both solid and liquid forms that can help supplement soil nutrients and support soil fertility. Unlike conventional synthetic fertilizers, products from GSR’s process may also provide secondary nutrients, trace elements, and organic matter that support plant growth, soil health, and overall crop performance. The platform also supports agricultural biological product pathways, including biofertilizers, biostimulants, biopesticides , and related products. These products have demonstrated strong yield performance in independent trials, and several are already available in the market.

GSR’s innovative process transforms clean organic waste streams into high-value antioxidants, feed ingredients, and supplement-related products for growing animal nutrition and nutraceutical markets. The platform supports product pathways relevant to a broad nutraceutical category, including food supplements, antioxidants, high-protein additives, and oils. It also supports the development of protein feed supplements for livestock animals. These products, rich in essential nutrients, include:
Animal Feed
Nutraceutical Supplements
Protein Supplements
Salmon Coloring
The GSR-BOLTTM is designed to improve the economic and environmental performance of digesters producing power and renewable natural gas by creating additional value from digestate and other low-value residual streams. Building on this foundation, GSR’s platform also supports pathways to advanced fuels and other higher-value energy-related products derived from nutrient recovery and algae-based intermediate processes. This work expands the potential of nutrient-rich organic residuals beyond waste management alone, helping connect resource recovery with broader energy and fuel opportunities. With our waste-to-value technology, we are uniquely positioned to reduce the cost of liquid fuel production, as demonstrated in our Farm to Fly project supported by fuel end users. This vision aligns with broader efforts to scale aviation fuel from agricultural and waste feedstocks.

Bio Molecules
Development of Bioplastics Algal-based bioplastics are in the early stages of development to meet the high demand in the bioplastics sector. Various bio-plastic opportunities in the market include cellulose-based plastics, poly-lactic acid, and bio-polyethylene. Our waste-to-value technology elevates this option to the next level, providing biodegradable alternatives to conventional plastics.
Emerging Chemical Molecules A new world of chemical molecules is emerging from algal-based feedstock inputs, including: Bio-succinic acid (an alternative to phthalic anhydride, adipic acid, and maleic anhydride) Arabinitol Aspartic acid Glucaric acid Levulinic acid Malic acids Sorbitol Succinic acid Xylitol We are collaborating with our partners to bring this potential to the market, harnessing the full range of chemical molecules derived from algae.
