Economic Solutions for a Sustainable Industrial Future
Advantages and Benefits
VOC emissions are a waste-to-energy opportunity fuel
VOC destruct removal efficiencies (DRE) achieve EPA and State air
pollution control standards
VOCGEN
Project economics provide a compelling case for use of energy
efficient combined heat and power for manufacturing industries
Operational savings provide a superior return on investment
when compared to conventional air pollution controls
The technology achieves a ≥50% reduction in carbon emissions
compared to purchased regional conventional generation
