INTRODUCTION TO THE SUNRISE PROJECT

The main objective of the H2020 SUNRISE project (GA 958243) is the development of an innovative multi-sensor classification tool based on online industrial techniques that allows optimal classification of laminated glasses according to the composition and degradation of the PVB polymer present as interlayer. So far, only 9% of post-consumer PVB is recycled into secondary uses. The objective of the project is to generate categories of different qualities of this polymer, allowing high-added value uses for the highest quality categories by reintroducing the material again in interlayers for laminated glass.

The SUNRISE project has a duration of 42 months, it is currently in the last year of execution where some of the main results achieved are the construction of the multisensor tool that combines optical methodologies and AI algorithms for the analysis and classification of PVB within the glass and that allows the identification of the type of intermediate layer, the type of plasticizer and degradation aspects based on the optical properties (haze). The system has been integrated in Lurederra Technological Centre facilities in Spain where the mechano-chemical treatment plant is located for the purification of PVB and a second demo has been installed in Italy. The project has also worked on the analysis and optimization of the mechano-chemical cleaning process depending on the type of waste, construction or automotive and is currently working on the use of recycled PVB in final applications. For the largest volume application such as interlayer in laminated glass which would mean unlocking high volumes of this waste, the project is currently working on mixtures of recycled and virgin material. The project developments and solutions are also being analysed using environmental and cost analysis tools where the benefits have been confirmed compared to the current situation of no recycling. Likewise, work is being done on the creation of a CEN working agreement (CWA) in relation to the recycling of PVB currently not treated within the standards and standardization committees. The main impact of the project will be to unlock a large amount of current PVB waste. More than 125,000 tons could be recycled and reused in high-quality applications that represent economic, environmental and social benefits.

INTRODUCTION TO THE SURVEY

This survey prepared within the SUNRISE project is dedicated to study the potential for transference and replication of the recycling line. If you are reading this and your company deals with laminated glass recycling,  filling this survey you are helping to understand the needs and requirements of the sector and how the prototype solutions developed could fit in your current business and/or which modifications and directions should be addressed when passing to an industrial scale installation. The survey is divided in two parts, first involves some questions in order to understand recycling practices currently used and second part is dedicated to obtain the feedback from the solutions developed. It will not take you more than 5 minutes. We appreciate that you can fill as much as possible questions. THANK YOU FOR YOUR COOPERATION!!
