Integrated technologies to recover metal and plastic from electronic waste

VTT Technical Research Centre of Finland has developed a new electronic waste recycling concept that combines a range of technologies and reduces waste. One of the technologies included in the concept is gasification, which is used to recover not only metals and rare-earth elements from the waste but also organic components that can be used to produce energy or products, such as plastic and chemicals. VTT has brought together a group of Finnish partners to promote material-efficient production.  Vast amounts of valuable raw materials are lost through recycling and processing: As much as

VTT recovering metals and minerals from waste

Scarcity of clean water is one of the most serious global challenges. In its spearhead programme, VTT Technical Research Centre of Finland developed energy-efficient methods for reuse of water in industrial processes and means for recovering valuable minerals and materials from waste for recycling. Rapid tools were also developed for identification of environmental pollutants. When water and wastewater systems are developed in a comprehensive manner, it is possible to recover valuable metals and other materials and secure availability of clean water. Cleaning and treatment processes can

More profitable biogas production by optimization of anaerobic waste digestion

VTT Technological Research Centre of Finland (VTT) coordinates a new European project, which focuses on studying anaerobic digestion (AD) of organic waste and developing its control. AD process can be optimized to produce either biogas or volatile fatty acids that are even more valuable products than biogas. The produced volatile fatty acids can be converted further to raw materials with which it’s possible to produce oil-replacing biobased products, such as bioplastics. During the anaerobic digestion process, which contains four main steps, the organic matter is degraded by bacteria to

Towards better recovery of waste resources

Finnish researchers evaluate waste chain development needsA considerable amount of valuable raw materials is lost in waste utilization and processing chains. It would be worth, for example, effecting better recovery of the valuable metals contained in electronic equipment. Research carried out by VTT Technical Research Centre of Finland, Aalto University, the Finnish Environment Institute (SYKE) and Lappeenranta University of Technology has provided new information on the development needs of waste management.Waste is being turned into a global trading commodity. Stricter recycling
