Lignin is a natural biopolymer found in plant cell walls and produced in large quantities worldwide as a by-product of the paper and pulp industry. Thanks to its versatile properties, lignin has numerous potential applications – for example, as a raw material for bio-based plastics, binding agents, cosmetic products, battery materials and building materials.
Lignin could be a game-changer for greater economic efficiency and sustainability in industry
Lignin thus plays a central role in the development of sustainable alternatives to fossil raw materials such as petroleum or coal. Despite its enormous potential, lignin has only been used to a limited extent as a material to date. Economic and regulatory hurdles are hampering the market launch of innovative lignin-based products. There is a lack of uniform standards, and cooperation between stakeholders in the value chain still has room for improvement. This is the conclusion of the latest analysis of the lignin value chain as part of the "Bioeconomy Deep Dives" conducted by the innovation hub RootCamp on behalf of Landwirtschaftliche Rentenbank and the Federal Ministry of Food and Rural Affairs (BMLEH). The study identifies concrete solutions for how lignin can become a key raw material for the bioeconomy.
