Lignin

Lignin is a natural adhesive, and is a green alternative to some of the glue components used in plywood and wood panel manufacturing. Research is underway to use lignin as a renewable, natural replacement for certain glue components used in the manufacture of plywood and engineered wood products such as laminated veneer lumber and oriented strand board. 

Lignin also offers potential for a wide variety of other novel applications, which includes resins, fuels, water and air filtration systems, rubber additives, thermoplastics, pharmaceuticals, and insulating foams.
Research is continuing on making carbon fibre from lignin that could be used in high-end sporting equipment such as bicycles, golf clubs and tennis racquets. Wood fibre has the potential to play a major role in the largest manufacturing revolution this century ― providing substrate for 3D printers from lignin, an affordable and renewable by-product of pulp mills.
