Certification included an audit performed by independent third party auditor, Carolina Management System Services. Chris Garth, who completed the audit, said the biodiesel coming out of the Big Island plant "is made efficiently, yielding high quality fuel," and the company has developed "an organizational culture that scores very high – and drives continual improvement – in quality, environmental, health, safety and sustainability metrics.”
The audit considered a range of areas, including air emissions, water consumption savings, energy consumption, purchasing policies and community benefits. The review also considers if the facility is consistently working towards zero-waste production.
The sustainable sourcing, manufacturing and use of renewable fuel sources like biodiesel is critical for Hawaii, which has a 100% renewable energy mandate it must meet by 2045. In its most recent power supply plan, the Hawaiian Electric Company estimated that biofuels will make up more than a quarter of its generation supply by that time, though that number could increase if advances in biofuel production lowers prices.
