Laboratory Scale Production of Pine Needles Based Adhesives and Coatings, G.S. Chauhan, Department of Chemistry, HPU, Shimla - 5

The present report contains information regarding the preparation of novel adhesives for multiple applications from dried and fallen pine needles. Pine needles constitute a huge natural forest waste feedstock of cellulose, that is abundantly available in the Himachal Himalaya. In this study the investigator has utilized pine needles to extract cellulose for use as supports for enzyme immobilization and sorption of metal ions. This renewable resource has be modified as adhesives for specialty applications by combination with the other component to keep the final formulation low cost, eco-­friendly yet effective for use in biomedical and industrial applications. One formulation, despite its better scientific attributes, is not commercially viable as one of the components is high cost prohibitive (approximately, Rs. 5,000/-per Kg). It follows that eco-friendly and low cost specialty adhesives can be successfully prepared and good commercial potential.
