With the constant increase of oil prices and with the dwindling of fossil resources, "green" alternatives must be found. Thus, first research was conducted on the possibility to develop synthetic phenolic adhesives for wood-based panels where a part of phenol was substituted by wheat proteins. Similarly, tannins which are natural polyphenolic molecules can be used as an alternative to synthetic chemical products. Chestnut tannin, a hydrolysable tannin was used to substitute part of phenol during the synthesis of phenolic resins. The characteristics of these resins were studied and the resins used for the manufacture of rigid phenolic foams. This is a new step towards the development and future commercialization of more environmentally frien...
