Dare to be sustainable
For years humankind has burned lignin instead of using it as nature intended – as a superior adhesive. We are here to change that approach.
The VIOBOND consortium aims to take essential commercialization steps based on the natural wood component lignin, creating industrial technologies to significantly reduce the share of fossil raw materials in phenol formaldehyde resin, which is widely used in various everyday products.
Under the auspices of the VIOBOND project, a first-of-its-kind flagship plant producing industrial-scale lignin phenol-formaldehyde (LPF) resins will be built in Latvia during the next five years. Production capacity of environmentally friendly resin will reach 45,000 tons per year and renewable lignin will replace over a third of the fossil materials used traditionally. Consortium members will use new resin for plywood manufacturing and coating, sandpaper adhesive and glass wool thermal insulation binder.
Why Are We Joining This Initiative?
The main target of the project is to build a new bio-based resin plant in Latvia, utilizing lignin from different biorefineries to partially replace phenol and formaldehyde in a variety of resin products.
Besides the resin value chain, there are also other lignin valorisation pathways to improve utilization of this valuable bioproduct. Lignin in composite application, as a replacement for bitumen in asphalt, advanced fuels and lignin carbon applications are currently among the most promising commercialization routes.
How Are We Going To Achieve This?
Replacing Toxic With Natural
Most plants, including trees of all species, contain 20-30% of lignin, a natural biopolymer that together with cellulose and hemicellulose forms the wood cell structure that allows trees to grow in length.
Nowadays, science and technologies have developed to the point that people can divide wood into its components. Phenol and formaldehyde, which are the compounds of the most commonly used resins, are harmful to humans, whereas lignin is a natural, sustainable by-product.
Extracted From Wood
Non-modified lignin is extracted from wood by means of unique technologies. After this process, lignin is already suitable for modification, which will be used for production of lignin-based resins for wide industrial applications. Examples include plywood, thermal insulation, sandpaper, floor and furniture production, etc.
Lignin resin can be used not only to produce plywood, but also in production of impregnated paper, which is used for plywood to reduce any unnecessary friction.
Historically, lignin was a by-product in the production of pulp, which, together with other by-products, was mainly used as a fuel for energy production. In recent years, the development of novel wood-processing technologies has made it possible to extract from wood chemically non-modified lignin highly suitable for further chemical modifications and functionalization.
