Starch adhesive innovation for green adhesives

Innovation is of major importance to AVEBE

Besides continuously optimising current products, production process and adhesive recipes, we are working on the development of the next generation of starch based adhesives. The second topic is to (partially) replace synthetic adhesives. The replacement is based on the 12 principles of green chemistry by Paul Anastas.

The next generation starch based adhesives

AVEBE has a new and unique starch: waxy potato starch. Waxy potato starch contains over 99% amylopectin molecules and with the highest purity (low fat or protein content) of standard potato starch.

Pure amylopectin starch allows the development of adhesives with unique viscosity/dry solids ratio, better visco-stability, unique clarity and higher wet tack. It is the world's first amylopectin potato starch obtained through traditional and well accepted plant breeding techniques.

Synthetic polymer replacement

Important challenges facing adhesive manufactureres and users are increasing raw material costs, reducing carbon footprint and the forthcoming REACH legislation, the changing legal requirement from the EFSA.

One way to deal with these challenges is the replacement of adhesive systems based on synthetic adhesives with systems based on starch derivatives. AVEBE is developing products which (partially) replace typically synthetic adhesives like polyvinylacetate disersions (PVAc), polyvinyl alcohol (PVOH) in various markets.

Following the 12 principles of green chemistry by Paul Anastas

Prevent waste: Design chemical syntheses to prevent waste, leaving no waste to treat or clean up.
Safer chemicals and products: Design chemical products to be fully effective, yet have little or no toxicity.
Less hazardous chemical syntheses: Design syntheses to use and generate substances with little or no toxicity to humans and the environment.
Use renewable feedstock: Use raw materials and feedstocks that are renewable rather than depleting. Renewable feedstocks are often made from agricultural products or are the waste streams of other processes; depleting feedstocks are made from fossil fuels (petroleum, natural gas, or coal) or are mined.
Use catalysts, not stoichiometric reagents: Minimise waste by using catalytic reactions. Catalysts are used in small amounts to carry out a single reaction many times. They are preferable to stoichiometric reagents, which are used in excess and work only once.
Avoid chemical derivatives: Avoid using blocking or protecting groups or any temporary modifications if possible. Derivatives use additional reagents and generate waste.
Maximize atom economy: Design syntheses so the final product contains the maximum proportion of the starting materials. There should be few, if any, wasted atoms.
Use safer solvents and reaction conditions: Avoid using solvents, separation agents, or other auxiliary chemicals. If such materials are necessary, use innocuous chemicals. If a solvent is necessary, water is a good medium as well as certain eco-friendly solvents that do not contribute to smog formation or destroy ozone.
Increase energy efficiency: Run chemical reactions at ambient temperature and pressure whenever possible.
Design chemicals and products to degrade after use: Select chemical products which break down to innocuous substances after use so they do not accumulate in the environment.
Analyze in real time to prevent pollution: Include in-process real-time monitoring and control during syntheses to minimize or eliminate the formation of by-products.
Minimize the potential for accidents: Design chemicals and their forms (solid, liquid, or gas) to minimize the potential for chemical accidents including explosions, fires, and releases to the environment .
