Renewable Energy Group (REG) has completed upgrades to its 30 million gallon biorefinery in Newton, Iowa, US.
The plant can now produce an even higher purity biomass-based diesel from a variety of raw materials.
REG started work on the $13.2 million (€11 million) project in February and completed it in November, four months ahead of schedule and on budget.
A further $2.6 million was invested to expand storage capacity by 2 million gallons and improve logistics, for a total investment of $15.8 million.
The upgraded process, including distillation, removes impurities and creates a pure form of biomass-based diesel. The final product exceeds industry quality standards and meets REG's rigorous REG-9000 specifications.
'This increased feedstock flexibility drives demand for local feedstock suppliers, enabling them to keep their products in the region,' says Brad Albin, VP of manufacturing, REG.
