VTT to add new methods to the plastics recycling chain

Thermochemical treatment to recycle low-quality plastic wastePress release 11 June, 2019 A portion of collected plastic waste does not qualify for mechanical recycling and ends up incinerated instead. VTT complements the selection of sustainable recycling methods with chemical recycling based on pyrolysis, which will turn nearly all plastics and their mixtures into oil – the raw material of fuels, plastics and other chemicals. Mechanical recycling suits the most common plastic bottles, bags and wraps. They are sorted, washed, melted and moulded into new products. However, 40 to 60

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: Demolition planning as part of construction – reuse and recycling of parts improves the eco-efficiency of buildings

With good planning, it is possible to promote the reuse of construction and demolition waste and thereby both conserve the environment and save on material costs. In the future, it will be even more important to assess how buildings can reasonably be repaired or demolished into parts, together with how the remaining service life of the parts can be utilized in new applications. The best method is to implement demolition planning already as a component of construction design.Reuse of construction parts is always worthwhile from the perspective of the environment, and can also be

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

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
