A nontoxic glue for plywood — from glucose, citric acid

The go-to materials for building home furniture, décor and floors are composite wood products that come in large sheets. But the glues and resins holding together particleboard, fiberboard and plywood usually contain formaldehyde and could release this probable carcinogen into the air. To develop a nontoxic adhesive, researchers have combined glucose and citric acid — sugar and an orange juice ingredient — into a strong, water-resistant wood glue for plywood.
