Proof of Concept
Integrating energy efficiency monitoring,
control and optimization for plastics industry
• Develop a new generation of low cost energy monitoring system which can be easily
integrated with existing or new processes and validate it on a wide range of extruders.
• Build intelligent energy efficient control and optimization system and merge functions
from 1.
• Patent the concept and develop a prototype system for dissemination and exhibition.
