Recover Nutrients. Create Value. Support Cleaner Water.
GSR BOLT™ helps farms, digesters, processors, utilities, and project partners convert nutrient-rich liquid residuals into recovered fertilizer, recycled water, and other resource pathways.
Core Platform
GSR BOLT™ is the platform foundation.
GSR BOLT™ is GSR’s core nutrient transformation platform for manure, digestate, food-processing residuals, and other nutrient-rich liquid streams.
Receives
Nutrient-rich liquid residuals from farms, digesters, processors, and related sites.
Recovers
Targets nitrogen, phosphorus, organic value, and recoverable material streams.
Converts
Routes recovered value into fertilizer, recycled water, and other useful outputs.
Integrates
Fits around existing farm, digester, processor, and project infrastructure.
Platform Overview
From liquid residuals to recoverable outputs
The GSR BOLT™ platform captures nitrogen, phosphorus, and organic value from nutrient-rich liquid waste streams, then routes that value into fertilizer, cleaner recycled water, and other resource-recovery pathways.
The same core platform can be configured for digester and non-digester sites, depending on the waste stream, operating environment, and desired outputs.
How the Platform Works
A practical recovery sequence
The platform uses a configurable process that combines treatment, nutrient capture, separation, and output development.
Receive
Take in nutrient-rich liquids such as manure, digestate, food residuals, or processing wastewater.
Treat
Use biological treatment to help transform the liquid stream and support nutrient capture.
Separate
Use physical separation to route captured value into more useful and manageable streams.
Reuse
Create pathways for fertilizer, cleaner recycled water, and other site-specific resource outputs.
Where It Fits
GSR BOLT™ fits where nutrient-rich liquid residuals create treatment, hauling, land-application, or water-quality challenges that can be improved through recovery and reuse.
- Farms managing manure or digestate
- Digesters producing nutrient-rich liquid effluent
- Processors with organic and nutrient-rich residuals
- Sites seeking fertilizer, water, or resource-recovery outputs
Conservation Relevance
“Managing nutrients in manure and wastewater is a priority for protecting soil and water resources. Waste treatment and nutrient management practices can help address on-farm nutrient challenges and support water quality goals. Demonstration efforts evaluating nutrient recovery approaches, including one demonstrated with GSR Solutions, can expand the options producers can consider as part of conservation planning in different farm settings.”

Technology Pathways
One platform, multiple configurations
GSR BOLT™ is the core nutrient-recovery platform. Its pathways are configured around site type, waste stream, and desired outputs.
AD BOLT™
For anaerobic digester operations managing liquid digestate.
BOLT FLO™
For farms, processors, breweries, and sites managing nutrient-rich residuals without digesters.
BOLT Harvest™
For nutrient recovery and fertilizer-output pathways.
BOLT ClearFlow™
For optional water polishing and cleaner recycled-water pathways.
AD BOLT™ for Digester Operations
Anaerobic digesters can generate electricity, biogas, or RNG while still leaving nutrient-rich liquid digestate that requires downstream management. AD BOLT™ adds a nutrient-recovery and value-creation layer.
- Designed for dairy, food-waste, and mixed organic digesters
- Targets nutrient recovery from liquid digestate
- Supports fertilizer production and cleaner water-output goals
- Can improve digestate management and project economics
BOLT FLO™ for Non-digester Operations
Not every site has or needs an anaerobic digester. BOLT FLO™ is designed for livestock farms, food processors, breweries, and other operations managing nutrient-rich liquid residuals.
- Designed for non-digester sites
- Applicable to manure, food, and beverage residuals
- Supports treatment and nutrient recovery goals
- Creates pathways for fertilizer and resource value
Implementation
From screening to commercial deployment
GSR BOLT™ can be deployed based on site readiness, project goals, waste-stream data, and commercialization needs.
Feasibility Screening
Initial review of site conditions, waste-stream profile, nutrient characteristics, operating constraints, and recovery potential.
Pilot Validation
Site-specific testing to evaluate recovery performance, product outputs, water quality, operating requirements, and integration needs.
Commercial Implementation
Deployment support for nutrient recovery, fertilizer production, optional water polishing, project integration, and long-term operating alignment.
Agriscience Platform
From recovered nutrients to plant nutrition
GSR Agriscience develops organic fertilizer and plant nutrition products that help return recovered nutrient value to productive use in crop, soil, and garden applications.
GSR collaborates with the NutriHarvest® platform to connect recovered nutrient streams with product development, field validation, and market channels.
Resource Recovery and Energy-Linked Pathways
Selected opportunities where feedstocks, site goals, and economics fit
GSR’s broader waste-to-value experience can support selected resource-recovery and energy-linked opportunities where project conditions align.
Waste-to-Value Platform Logic
GSR’s patented nutrient transformation capabilities connect waste management, recovered biomass, fertilizer production, agriscience, and downstream waste-to-value opportunities where project goals align.
Farm-to-Fly and Fuel-Linked Pathways
GSR supports partners evaluating how recovered nutrients, biomass, and organic residuals can be converted into higher-value products through project collaboration, technical support, and technology licensing.
- Alternative liquid-fuel pathways
- Digester value enhancement
- Recovered biomass opportunities
- Resource-recovery project development
GSR Insights Series
Managing Waste Runoff Nutrients
Excess nutrients, particularly nitrogen and phosphorus, from farms, food and beverage facilities, and anaerobic digesters can become runoff. Practical nutrient recovery can help keep these nutrients in productive use instead of becoming pollutants.
Platform FAQs
Common questions about GSR BOLT™
Answers about the platform, how it fits into farm and digester operations, and how nutrient-rich residuals can become useful outputs.
What does GSR’s platform do?
GSR’s platform is designed to recover nutrients from manure, digestate, food and beverage residuals, and other nutrient-rich liquid waste streams. The recovered nutrients can then be directed into fertilizer, recycled water, biomass-based materials, and other resource-recovery pathways.
What does “bolt-on nutrient recovery” mean?
“Bolt-on” means the platform is intended to integrate with existing farm, digester, waste-management, or processing operations rather than replace the entire site infrastructure.
What types of sites can use the platform?
The platform is relevant for dairy farms, anaerobic digester operations, food and beverage processors, utilities, municipalities, renewable energy project partners, and other sites managing nutrient-rich organic residuals.
Does the platform work only with anaerobic digesters?
No. GSR’s platform can support digester-based and non-digester applications. For digester sites, the system can be configured to treat liquid digestate. For other operations, it can be evaluated for manure, agricultural wastewater, food-processing wastewater, or other organic liquid streams.
What comes out of the system?
Outputs depend on the site and configuration, but may include recovered nutrient materials, organic fertilizer pathways, cleaner recycled water, biomass-based intermediates, and other value-added resource-recovery streams.
How does this support water quality?
By capturing nutrients before they are lost to water systems, GSR’s platform is designed to help reduce nutrient-loss risk and support cleaner water-management outcomes.
