The development of the Weyland process started in the laboratories at the Bergen University College in 1987. Our technology is based on concentrated acid hydrolysis, and makes it possible to produce bio-ethanol from cellulose-containing materials which is not suitable for food, so called second-generation bioethanol.
Video presentation:
The process has been developed and refined based on more than 1000 lab and bench scale test. A wide variety of feedstock has been tested, including soft wood, hard wood, bagasse, corn cobs, rice straws etc.
The results have proved that the process is very robust and provides a high yield, independent of feedstock types.
The technology has several advantages, amongst other:
- Flexible with regards to feedstock
- High ethanol yield
- Very good industrial scalability
- The process is largely driven by low grade energy, and can therefore utilize waste heat in the production
