Sandwell is reviewing all technology documentation provided by Raven and discussing the findings with specialists who are advisors to Raven that were involved in extensive pilot scale testing and research on this technology. This will form a report to identify areas that require further focus for the final engineering package. Sandwell's findings on furfural and ethanol yields from lodge pole pine, benefits of integrating with existing pulp mills, and suggestions on further improvements will require further development during subsequent phases of this project. Further lab testing or pilot plant runs will be required to confirm design criteria parameters for commercial development of the refinery.
