Research Note: Eco-design of self-condensed tannin-based adhesives: A viable economic solution?
Tannins are chemical compounds that are widely distributed in all plant species. In the search for adhesives with low environmental footprints, tannins provide a great option. Tannin, although derived from forest industry residues, is relatively expensive, with costs in the order of $ 1,900 / tonne. This work explores the economic aspects of the development of self-condensed tannin-based adhesives. It has been observed that the high production costs of adhesives are largely attributable to the price of tannin. However, this study demonstrates at a cost of $ 1,900 / tonne of dry tannin extracts, the industrial production of self-condensed tannin-based adhesives could be profitable in Canada.
