Wood and its derivatives are highly attractive materials, not only due to their sustainability, low cost, and biodegradability, but also because of their intrinsic porous and hierarchical structure, excellent mechanical properties, and versatile surface chemistry. In this work, we present an ionic diode based on bipolar membranes fabricated from two oppositely charged wood membranes. The […]

This research explores the valorization of rice husk lignin, a renewable and low-cost agricultural byproduct, for the development of multifunctional, eco-friendly materials and cosmetic products. Lignin, a natural phenolic biopolymer, possesses intrinsic UV-blocking and antioxidant properties, making it a promising alternative to synthetic polymers and chemical UV filters. The study focuses on synthesizing spherical lignin
This multidisciplinary project tackles two key environmental challenges in Sweden and the EU: reducing peat extraction and managing sludge waste from pulp and paper mills. By repurposing abundant mill sludge as a sustainable alternative to peat, the project aims to advance peat-free mushroom cultivation—particularly for peat-dependent species such as the common button mushroom. The research
The construction sector in Sweden stands for about 22% of total greenhouse gas emissions. Reducing the embodied carbon in new buildings can be achieved by a transition to bio-based insulation materials since conventional insulation accounts for about 20% of the total embodied carbon. Additionally, bio-based materials are hygroscopic, i.e. they absorb moisture from the air
Our projects focus on the use of biopolymers such as cellulose, lignin, tannins and hemicellulose in formulations ranging from therapeutics, to home and personal care, agrochemicals and additive manufacturing, with the goal of reformulating without synthetic polymers. We are particularly interested in the use of green deep eutectic solvents to extract and modify cellulose, and

Cellulose is a renewable and biodegradable material, but its natural structure limits its use in some applications. Chemical modification can impart new properties to cellulose and expand its applications. This project will investigate methods to enhance cellulose reactivity and accessibility, aiming to improve the production of cellulose derivatives.https://www.kth.se/fpt/woodchem/research/cellulose-for-high-performance-derivatives-1.1244385
