Recovery Machinery Standards
Eight standard series covering anaerobic digesters, gas upgrading, CHP systems, feedstock preparation, and modular equipment — all tested and certified through accredited laboratory partners.
Standard Series
Performance and safety standards for anaerobic digestion reactors from 500 m³ to 25,000 m³, covering gas yield verification, process stability, mixing efficiency, and structural integrity testing.
Testing standards for biogas cleaning, H₂S removal, moisture control, siloxane treatment, and membrane upgrading systems, defining methane purity and contaminant limit compliance.
Certification for biogas compression, storage, and dispensing systems, verifying fuel quality, pressure safety, and dispensing infrastructure compliance for vehicle-grade renewable gas.
Performance standards for combined heat and power units and biogas engines from 100 kW to 10 MW, covering electrical efficiency, heat recovery, and grid synchronization compliance.
Testing protocols for de-packaging systems, macerators, pasteurization units, and hygienization equipment used in organic waste processing and anaerobic digestion feedstock preparation.
Standards for digestate dewatering, separation, and treatment systems, verifying nutrient content, pathogen reduction, and output quality grade compliance.
Scaled testing standards for containerized digesters, modular upgrading skids, and mobile waste-to-energy units, enabling certification of decentralized processing equipment.
End-to-end certification framework covering design review, laboratory testing, field commissioning verification, and ongoing surveillance for complete recovery and energy systems.
Why Standards Matter
