Shell Fiber Conversion Technology

Shell Fiber Conversion Technology is a bolt-on technology that enables producers of first-generation ethanol to significantly increase their profitability.

It converts lignocellulosic biomass, such as wet distillers grains (WDG) from corn ethanol plants, into enhanced-protein animal feeds, distillers corn oil (DCO) and cellulosic ethanol.

In addition, the Shell process uses a reusable acid, and the low-temperature operation is intrinsically non-fouling, which helps to reduce maintenance costs and improve the on-stream factor.

Shell’s Experience in Fuels and Biofuels

Shell is one of the world’s largest traders and blenders of biofuels. In 2019, we blended about 10 billion liters of biofuels, thereby helping retail customers decarbonize millions of journeys each year.

Benefits of Shell Fiber Conversion Technology

The technology enables corn ethanol producers to shift their product portfolio – making it both more valuable and more resilient. The process converts high fiber and relatively low-value products (WDG) into the following high-value streams:

  • Enhanced-protein animal feeds, which command a higher sales value than the feeds produced by first-generation ethanol plants, and are in high, and growing, demand.
  • DCO, which can be used as an advantaged feed for hydrotreated vegetable oil (HVO) units, including the Shell Renewable Refining Process. The technology can double the total DCO output of a dry mill.
  • Cellulosic ethanol, generating D3 RINs.

In addition, the technology has been designed with a focus on achieving benchmark levels of operability, reliability, and energy efficiency.

Shell Renewable Refining Process

Refiners can make profitable renewable fuels, comply with biofuels legislation, and generate trading credits with our HVO technology, the Shell Renewable Refining Process.


Co-processing renewable feedstock can be a low to no capital cost response for producing hydrotreated vegetable oil (HVO).
