What "Performance" means to us
Performance Isn’t Just Efficiency — It’s Environmental Responsibility.
At SG, performance is more than processing capacity. It's about protecting air quality, safeguarding water resources, controlling odors, ensuring regulatory compliance, and producing compost that's clean, safe, and market-ready
Our SG ADVANCED COMPOSTING™ Technology is designed to exceed environmental benchmarks, reduce risk, and optimize operational outcomes.
COMPLIANCE AND PERFORMANCE FACTS FOR SG COMPOSTING SYSTEMS:
- Pathogen Reduction and Hygenization
- Meets PFRP, VAR, Hygiene, and ABPR EPA 503: Alt 5: Use of PFRP [503.32(a)(7) and (B)(1) of Appendix B]
- Effective Odor Control for Good Air Quality - Odor reduction 90-95% (Odor emission study)
- VOC emission: US/Cal: > 95% (independent third-party testing). Applicability to California air district rules is evaluated for each facility and permit
- Greenhouse Gas Control
- Aerobic, positively aerated process designed to limit methane and other greenhouse gas emissions (CO2 equivalent)
- Dust and Bioaerosol Control Bacteria retention > 99%, e.g. Aspergillus fumigatus
- Dust and Particulate Matter (PM) Retention > 99% (Thesis Dr. Kühner: Emission Study ) Water Protection
- Waterproof GORE® Cover Protection from groundwater contamination
- Clear separation of leachate from stormwater
Validated Environmental Performance
Certified. Repeatable. Reliable. Reproducible
SUSTAINABLE GENERATION® is more than a name. It’s a performance standard.
From VOCs and odors to permitting and scalability, SG ADVANCED COMPOSTING™ Technology helps facilities succeed in the field, not just on paper.

Independent Third-Party Validation You Can Trust
SG ADVANCED COMPOSTING™ Technology has been rigorously vetted and certified by top regulatory agencies, universities, and environmental engineers.
Why it matters:
Independent validation protects your project’s credibility, secures easier regulatory permitting, and ensures you meet air and water quality requirements without guesswork.
EPA Part 503 Pathogen Reduction:
Designed and operated to meet applicable Part 503 PFRP time-and-temperature requirements when approved operating procedures and project conditions are followed, supporting Class A biosolids compost.
California Air Quality Regulators:
More than 95% VOC control in independent third-party field testing. Certain tested configurations have demonstrated performance relevant to SCAQMD and San Joaquin Valley APCD composting rules; applicability is evaluated for each facility and permit.
Independent Municipal Pilots:
Performance verified through side-by-side city trials at regulated municipal sites.
