Lignin as Material of the Future: Key Information and Development Prospects

Abstract

In the article was given toward the aspect of homogeneous and heterogeneous depolymerization of lignin in ionic liquids. Thus, their roles and the mechanism of possible depolymerization of, for example, β‐ O ‐4. The presentation of possible ways to modify ionic liquids, including oxidation, which would allow to transform the biopolymer into a functional component of advanced hybrid materials was also an important aspect of the study. In addition, the study highlights the properties and use of exemplary lignin systems. The review was summarized and perspectives of further development were presented, with special attention directed to, for example, obtaining materials with defined properties, which may be used as potential platforms for the construction of modern biosensors, functional fillers for polymers, or electrochemically active materials.

Synthesis and Application of Modified Lignin Polyurea Binder for Manufacturing a Controlled-Release Potassium Fertilizer

“…Taking into account the growing shortage of petrochemical resources, it became imperative to develop technology capable of relieving the stress of raw materials in polyurea production. Lignin is the largest natural aromatic biopolymer with rich hydroxyl groups, a low production cost, and eco-friendly behavior [41]. The global production of industrial lignin, a by-product of the paper and hydrolysis industries, is 15 billion tons per year, yet the majority is burned or leached into the environment as wastewater, posing a serious threat to the environment in the course of processing [42].…”
