Title: Innovations by Tarja Tamminen
Introduction
Tarja Tamminen is an accomplished inventor based in Espoo, Finland. She has made significant contributions to the field of materials science, particularly in the extraction and application of valuable components from natural resources. With a total of three patents to her name, her work focuses on sustainable solutions for packaging materials.
Latest Patents
One of Tarja's latest patents is titled "Extraction of Valuable Components from Bark." This invention relates to a process for extracting valuable components from tannin-rich bark raw material. The process involves an alkaline cooking step followed by acid precipitation to separate the valuable components from the remaining bark pulp. This innovative method can be applied to a bark side stream of a chemical pulping plant, allowing the liquor remaining after extraction to be returned to the wood pulping process. The spent pulp can also be further processed, such as by bleaching to produce dissolved pulp.
Another notable patent is "Functionalized Lignin and Method of Producing the Same." In this study, commercially available softwood lignin was esterified with tall oil fatty acid (TOFA) and tested as a barrier material in fiber-based packaging. The modified lignin samples were applied to paperboard substrates, resulting in a significant decrease in water vapor transmission rate (WVTR) and oxygen transmission rate (OTR). The modified lignin coatings exhibited a high and stable contact angle without affecting the tensile strength of the paperboard. This demonstrates the potential of converting lignin into a value-added product, showcasing promising properties for sustainable barrier materials in packaging.
