LignoLight
LignoLight is a carbon-based material (carbon quantum dots) produced from wood waste, more specifically from lignin, that has UV light absorption properties. It offers a more environmentally friendly and safer alternative to the UV-protection additives currently on the market, which may contain metals or are often petroleum-based. This additive can be used, for example, in food films, food packaging, or cosmetic products such as sunscreens. As carbon quantum dots are highly effective UV blockers, this solution is well suited for products that need protection from UV radiation, for example to help extend the shelf life of certain products.
LignoPrint
LignoPrint is a 3D printing material made from wood waste, specifically lignin, where up to 30% lignin is added to conventional PLA material. This solution is more environmentally friendly and potentially more cost-effective, as it reduces the amount of PLA required. The added lignin also improves the material’s properties, making it more heat-resistant and easier to print. The solution is designed for use in commercial 3D printers and is particularly suitable for prototyping. This material could be of interest to educational institutions as well as industries moving toward more sustainable and environmentally friendly production.
LignoQuat
LignoQuat is an antibacterial additive for textile coatings derived from wood waste, specifically lignin. It gives fabrics antimicrobial properties without the use of metals or toxic chemicals. The solution offers a more environmentally friendly and safer alternative to current silver- or chemical-based antimicrobial treatments used, for example, in medical and workwear textiles. Its main applications include medical textiles, protective clothing, and other hygiene materials where reducing the spread of bacteria is essential.
