Technical lignin uses
WebbLignosulfonates (LS) are water-soluble anionic polyelectrolyte polymers: they are byproducts from the production of wood pulp using sulfite pulping. Most delignification in sulfite pulping involves acidic cleavage of ether bonds, which connect many of the constituents of lignin. Sulfonated lignin (SL) refers to other forms of lignin by-product, … WebbFör 1 dag sedan · Lignin fibers made from an aqueous solution of lignin, stabilized and carbonized endlessfibers. Photo: DITF A novel, both environmentally friendly and cost-saving process for the production of carbon fibers from lignin has been developed at DITF. It is characterized by high energy-saving potential. The avoidance of solvents and the use…

WebbLignin is one of the most abundant natural polymers. Produced as a by-product from the bio-refinery industries, it remains largely underutilised in high-value industrial applications. The valorisation of lignin in rigid polyurethane foam (RPUF) has been the focus of research, due to its potential to replace WebbWhile Kraft lignin is mainly used internally, lignosulfonates do have a market al-ready. From the annually 50–70 M tons produced lignin, just 1–2% are used for the pro-duction of added-value products. Lignosulfonates have more sulfur groups than Kraft lignin and thus are water soluble, which lead to a broad variety of products for lignosul-
