Eversa® Advance

Don’t let FFA be a bottleneck in your biodiesel production. Process feedstocks with up to 20% FFA now

Enjoy smooth plant throughput with maximized profitability

The high and inconsistent free fatty acid (FFA) content in waste feedstocks is a challenge for many biodiesel producers, and often results in bottleneck issues and feedstock wastage. Eversa® Advance is a new enzymatic, biocatalyst specifically designed to convert up to 20% FFA of any feedstock to fatty acid methyl ester(FAME), ensuring no bottlenecks in production and ensuring that no feedstock is wasted. 

Eversa® Advance is easy to implement in your plant, making it ideal as a pretreatment for an existing transesterification process or as a drop-in solution replacing an existing acid esterification process. Expect reduced downtime and operating costs, and increased FAME yields with no side reactions.

Unlock the full potential of your biodiesel plant.
Advance your pretreatment. Advance your business. Advance today.

    Smooth plant throughput – avoid unexpected maintenance and yield loss from side reactions

Don’t let acid esterification reduce your returns

If you’re already converting waste feedstocks to biodiesel today, you’re likely running an acid esterification process. Acid esterification of waste feedstocks requires a high dose of acid and excess methanol. Acids are highly corrosive to equipment - resulting in significant maintenance cost and downtime. And the excess methanol requires rectification to be reused - increasing energy consumption and reducing throughput.

Eversa® Advance allows you to replace acids with enzymes (during pretreatment), while reducing the need for maintenance and methanol rectification.

So throughput won’t be reduced. Neither will your margins.

Don’t let waste
go to waste

Like many biodiesel plant operators, you want to start processing waste feedstocks, such as used cooking oil and tallow, at the lowest possible cost. High free fatty acid (FFA) content in waste feedstocks leads to soap formation during biodiesel processing, resulting in significant feedstock waste.

Eversa® Advance complements your existing transesterification process and selectively converts up to 20% FFA to FAME with easy implementation and low CAPEX.

So waste-based feedstocks are not wasted. And neither is your profit.

Successful customer implementation

Several biodiesel plants are already integrating Eversa® Advance to their operations.

One of the largest industrial biodiesel groups in Brazil, Olfar, was one of the first producers in the world to implement it in their plant.

According to Marcelo Pauletti, Head of Biodiesel at Olfar, “Eversa® Advance is a pathway to diversifying our feedstocks and more efficient processing of waste-based feedstocks as well as smoother operations and lower costs.”

How does the pretreatment of biodiesel feedstocks with Eversa® Advance work?

An add-on to your existing transesterification process, feedstocks are pretreated with Eversa® Advance, and then co-processed with chemical transesterification for on-spec biodiesel. If you already run an existing acid esterification process with alcoholic neutralization, Eversa® Advance can work as a drop-in solution that replaces your acid catalyst.
