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 FACTS FOR ALL 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%, thus California Compliant for 80% (acc. to Rule 1133.3, Rule 4565, Rule 4566 & BACT)
- Greenhouse Gas Control
- Lowest possible emission rate (CO2 equivalent) compared to all other technologies
- 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.
U.S. EPA Pathogen Equivalency Committee:
GORE® Cover was approved to reduce pathogens (PFRP) further, achieving Class A biosolids compost certification. (EPA Part 503)
California Air Quality Regulators:
Field-tested and validated for >95% VOC and odor reduction, meeting and exceeding SCAQMD Rule 1133.2 and San Joaquin Valley APCD Rule 4565 standards.
Independent Municipal Pilots:
Performance verified through side-by-side city trials at regulated municipal sites.

INTERVIEW WITH A BIOSOLIDS EXPERT
Biosolids expert Dan Collins, P.E., shares insights on safe, efficient composting.
Summary of Performance GORE® Cover and Negative ASP
GORE® Cover was evaluated to quantify the performance versus an existing negatively aerated static pile.
Composting Facility Delivers Significant Environmental Protection
The East Coast’s largest food waste composting site processes 57,000 tons of organics annually.
Exceeding Air Quality VOC Emission Regulatory Compliance in California
SG systems consistently meet and exceed California air quality regulations.
Positive ASP Composting: the Future of Organics
Two of the biggest issues faced by commercial composting operators are emissions (odor and VOCs) and moisture management.
