Ground limestone, which absorbs residual paint particles by means of a process known as dry separation, has proved extremely useful in the Paint Shop. 'No water is used in this method. Air containing ground limestone circulates in the system, capturing paint and varnish particles. At the same time, only 20% fresh air is supplied, which saves us 80% of the energy required for cleaning and preparing the air for the paint shop's operation,' explains Veronika Nýdrová from Paint Shop Process Planning. This pre-used raw material, which consists of paint-saturated limestone, finds a second application in a process called dry flue gas desulphurisation in the ŠKO-ENERGO heating plant.

Another example of a circular project is cooperation between Technical Development and the recycling company Praktik or granulate manufacturers to develop materials from used painted bumpers or to come up with ideas for reusing engine oil or brake fluid. 'We are also currently working on chemical recycling, which can use a thermal process to turn old plastic into virgin-quality material,' says Lukáš Zuzánek from the Corrosion, Weather Resilience and Material Development department. There are many concrete examples of the application of circular economy principles in the Czech carmaker, from increasing the proportion of recycled materials and reusing packaging in logistics to innovative technical solutions in manufacturing.
