Ensuring recyclability
For the first time, the new multi-year research project of the Fraunhofer LBF will provide answers to the recyclability of halogen-free flame retardant plastics and suggest ways to ensure recyclability. At the same time it will make an important contribution to the socio-political issues of resource efficiency and security. The research will be carried out as part of the project funding Industrial Community Research of the AiF (German Federation of Industrial Research Associations, here Forschungsgesellschaft Kunststoffe e.V., www.fgkunststoffe.de) and with the participation of member companies of PINFA. PINFA (Phosphorus, Inorganic & Nitrogen Flame Retardants Association, www.pinfa.org) represents manufacturers and users of halogen-free flame retardants and is part of the European Chemical Industry Council (Cefic).
The companies concerned will benefit from the new research project in many ways. They will be better able to use their own product waste in the case of flame-retardant formulations and to save costs. The findings will lead to enhanced quality products with high safety standards, potential hazards of degradation products will be identified and can be eliminated. . Competitive advantages will continue to exist for using recycled plastics as a marketing tool and for constructing new products based on them.
Companies will be able to implement results immediately
As the institute draws on application-relevant and current commercial formulations, interested companies will be able to implement the findings immediately and directly. The ability to reuse production waste using the knowledge gained will generate a definite competitive edge. When using recyclates, it will be possible to minimize risks such as product liability based on the data compiled.
Due to the targeted mechanical recovery of recycled halogen-free plastics, the research project will reduce the use of raw materials and contribute to conserving and using resources more efficiently. Thanks to the improved properties of recycled plastics, such as the mechanical characteristics, it will be possible to open up new applications for these recyclates and build up new business areas. With a market volume in Europe of three billion euros for halogen-free flame-retardant plastics, the Fraunhofer LBF estimates the potential cost saving due to using production waste at 150 million euros per year. The potential value for used plastics is significantly higher.
Recycling additives play an important part in quality improvement in the mechanical recycling of plastics. With the addition of customized stabilizers, compatibilizers and reactive additives, recycled materials achieve qualities that can compete with those of new material. The number of recyclate additives has increased considerably in recent years. The difficulty arising from this for producers is how to develop the best solution technically and economically for the desired property profile. This is where the Fraunhofer LBF with its plastics division is available as a neutral partner that is continuously extending its knowledge of recyclates.
