In a circular economy where discarded materials are recycled in resource efficient manners, also a successful shift of textile waste recovery, from incineration to high quality recycled textile fibers is necessary. It has been identified that blends containing elastane (strong increase on the market, common in stretch jeans and leggings) and nylon are very problematic components in recycling processes. This is where we will pursue a novel biological-based enzyme engineering strategy in concert with thermo-mechanical processes towards selective separation of these blends. This approach will further be implemented in case studies on selected products of high importance for the industrial partners, and the process will be supported by sustainability and cost assessments to ensure the environmental and economical relevance of the recycling scheme. The ambition of the project is to accelerate the shift of the Swedish textile industry towards a circular economy.

The European Commission’s ambitious renewable energy goals, 20-20-20 objectives and Strategic Energy Technology Plan (SET Plan) request new technological and non-technological measures. Biogas is one of the promising energy sources that is not fully employed yet as a part of national gas and electric grids. BIOFEGG project will tackle this shortcoming by standardizing biogas quality. The project develops and pilots new control methods for anaerobic digestion process and a novel biogas cleaning and upgrading method for siloxanes and terpenes. The project also demonstrates a recently developed innovative real- time monitoring system for the biogas quality. The connectivity of biogas plants to gas grids, biomethane filling stations and future electric generation systems are studied in the project taking into account both technical issues and non-technical issues like regulations, environmental aspects and financial framework. The project is conducted by an international team consisting of four industrial partners and four research partners.

The project aims to develop novel bio-based technologies for the selective separation and recovery of synthetic textile fibers for recycling in the textile industry. This is based on the use of enzymes that can metabolize or degrade highly specific macromolecules. While the degradation of cellulose by enzymes has been studied in nature for 150 years and has also been used for decades for engineering applications, enzymes that are also able to metabolize synthetic fibers have been developed quite recently. Due to the high specificity of these enzymes, it is possible to gradually "extract" valuable components from textile residual flows of multi-material composition and / or to recycle certain fibers by systematic and gentle separation of unwanted fibers.
