The SUNRISE project kicks-off

  • Energy and environment

SUNRISE is a H2020 funded project that stands for “MultiSensor sorting tools in a circular economy approach for the efficient recycling of PVB interlayer material in high-quality prodUcts from laminated glass coNstRuction and demolItion waStEs”.

Laminated glass is obtained by bonding glass layers using a polymeric interlayer. Polyvinyl Butyral (PVB) is used as interlayer in laminated glass and their use in construction components is growing, therefore the end-of-life should be addressed. In EU, glass waste from Renovation and Demolition are quantified on 1.540.704 tons/year. The proper recycling of all building glass waste could avoid 925.000 tons of landfilled waste every year. Up to now, most of the post-consume PVB material in laminated glass is incinerated/landfilled, and only a 9 % is recycled in secondary uses. Recycling of PVB present several difficulties related with the contents of glass, humidity, mixing of compositions and polymer Optical degradation which impede reusing as interlayer.

SUNRISE will demonstrate within the current glass recycling business the application of an innovative optical multi-sensor sorting tool based on industrial in-line techniques (Raman, IRS, Fluorescence and Optical Spectroscopy) and AI algorithms which will allow optimal classification of laminated glass according to composition and degradation.

The project has a total budget of ~9.5M€ and will run for 4 years. The consortium is formed by 20 European partners including L’urederra (leader), and the Solar Energy Materials and Systems group at IREC.

In this project, IREC will apply the expertise in quality control and industrial monitoring compatible with industry 4.0 that allows optimizing the production of complex materials, including laminated glass.

The kick-off meeting of was held online on June the 17-18th, 2021. You can find the link on cordis at
