Project Title: Development of green process technologies to produce chitosan from seafood shell waste

Applicant: Prof Chi Wai Hui, The Hong Kong University of Science and Technology

Total Approved Grant: $493,552

Duration: 1/6/2016 to 31/5/2017

Project Status/Remarks: On-going

Current chitosan production processes are highly polluting and use and discharge large volumes of contaminated acid, alkali and carbon dioxide gas. The study aims to modify the traditional chitosan production process with a view to developing a new Green Chitosan Production process based on:
(1) recovery of value-added by-products that are currently discarded as waste;
(2) reuse of energy by applying pinch analysis to optimize and recycle energy; and,
(3) recycle and re-use of unreacted raw materials for all the process chemicals involved.

Summary of the Findings/Outcomes:
To be available upon completion of the project
