Torrefaction is a heating process of biomass in a non-oxidizing atmosphere, necessary to improve raw biomass materials. Torrefied biomass properties include a lower moisture percentage, a higher energy density and heating value. Torrefied material is easier to grind and to pelletize. These properties all translate into a sustainable and economic higher value.

During this torrefaction process, combustible emission gasses are released. The Yilkins torrefaction technology brings these combustible emission gasses back into the main process to provide the required process heat, making Yilkins torrefaction a very economic technology.

Projects/partnerships  highlights

Thyssen Krupp selected the Yilkins torrefaction technology for the preparation of various biomass for their entrained flow gasification technology to turn biomass into high-quality syngas for production of SAF, renewable diesel, green hydrogen, chemicals, renewable electricity etc.

A major beer brewer has selected Yilkins drying technology turning spent-grains into local energy production. A pilot project is underway that may lead to implementation at 30 plants around the world.

Yilkins is developing a torrefaction plant for one of the largest Refinery and Petrochemical conglomerates in India

Developing a facility for a large, international biomass industry partner in North America.

Yilkins torrefaction technology has been selected by a Japanese company
