The start-up Saperatec has developed a process with which aluminium composites can be broken down into their individual components. The first commercial recycling plant is scheduled to go into operation at the end of 2022.<\/p>\n

In Germany, 18.7 million tonnes of packaging end up as waste every year. An innovative technology now makes it possible to break down aluminium composites into their individual parts. High-performance adhesives<\/strong> support the process.
\n<\/strong><\/p>\n

Flexible packaging often consists of so-called aluminium composites - with layers of polyethylene, aluminium and PET. These are firmly bonded with a two-component polyurethane laminating adhesive. After disposal, they can often only be utilised thermally. The adhesives industry is constantly working on ways to enable material recycling, develop high-performance adhesives that also support innovative recycling processes<\/strong>. The current example of the start-up Saperatec<\/a> shows that it can work when waste management companies and adhesive developers work together.<\/p>

Saperatec process contributes to the circular economy<\/strong><\/h2>\n

And this is how the process works: First, the material is shredded in order to maximise the contact surface for the Innovative release fluid<\/strong> to create. In the second process step, the shredded composite material is treated with it. The separation process takes place with stirring and heating and the individual fractions are present in the liquid.<\/p>\n

The highlight of the innovative technology: the composition of the separating liquid. It easily breaks down the path between the individual layers<\/strong> of the composite material in order to separate them and was formulated in such a way that it can separate aluminium foil composites, metal-coated composites and inner foils made of liquid cardboard - because these often accumulate as a mixture in household waste.<\/p>
