A new concept for a mobile sugar beet refinery plant with a pyrolysis plant has been developed in a cooperation between UT and WUR;
The mobile concept is sustainable, has promising characteristics:
A follow-up project is needed for a detailed design of the mobile concept, and further research on economic feasiblity is required!
Summary
Advantages: • Low transportation cost for sugar beet• Improved energy efficiency• Extended process season• Closed minerals cycle• Utilization of waste biomass
