Biocomposites are key to the sustainable transformation of our materials world. They combine renewable raw materials such as natural fibers with bio-based or recyclable plastics, thus enabling durable, functional materials with low environmental impact. Their potential lies primarily in circularity: Instead of disposable materials and waste, we are focusing on closed material cycles – a crucial step, especially in the plastics sector. Innovative approaches are creating new applications that combine ecological responsibility with economic benefit. Biocomposites thus create real added value – for the environment, the economy, and society.
