The process requires no added catalyst and no enzyme, removing two of the most expensive and maintenance-heavy inputs in biodiesel manufacturing. At WIE, the SimplEster add-on integrated directly into an existing sodium methylate transesterification system without replacing it, increased plant capacity by approximately 15%, and produced on-spec biodiesel. That flexibility matters for producers who need to stay under the 0.5 mg KOH/g acid-value threshold for finished fuel, as they may lack certain downstream processing equipment. 'For a producer already operating a sodium methylate system, adding SimplEster is a straightforward way to expand feedstock flexibility and capacity. Pairing it with CPM|Crown's sodium methylate biodiesel processing technology is a strong step forward for both companies.'
