“A biotechnology company hidden among the forests of southern Finland thinks trees can help sustainability in Europe to become deep-rooted.
Sustainable multi-purpose products
Researchers at Metgen Oy are mixing enzymes and biomolecules from wood and bark to replace raw oil-based materials. Some of these renewable biomaterials have already been developed and used in different solutions for the packaging and construction industries.
Toni Grönroos is the technology development director at the company. He says that their main application, so far, is a shield that improves paper strength and water resistance. But they are also working on resins for gluing plywood together and raw material to produce insulation materials for construction.
Biodegradable packaging
One particular solution aims to replace the petrochemical-based coating used in cardboard packaging. A complex process turns the formula developed by researchers into a coating for paper surfaces. These coated surfaces are then tested to check their strength and water resistance.
Liji Sobhana is an innovation manager at Metgen Oy. She explains that the main advantage of this product is that it’s recyclable, biodegradable and compostable. “It replaces all the fossil-based chemistries, which now go to the landfills and are not biodegradable”, she adds.
Researchers at Metgen Oy feel that their work is putting science to the use of a greener planet, to create a greener tomorrow….”
