Oregon State University researchers have discovered that sugar could replace some toxic binders in metals manufacturing.
Experts in adhesion science at the OSU College of Forestry have discovered that sugar could replace toxic resins used in the process of making molds for metals products. Its use would cost less than other binders and is much more environmentally friendly.
[Professor Kaichang] Li and an OSU faculty research assistant, Jian Huang, identified combinations of sugar, soy flour and hydrolyzed starch — or even just sugar by itself — that should work effectively as a binder in sand molds for making various types of metal parts.
