The article presents the research results on the influence of the PVD coating on the cutting tool on the surface roughness and energy consumption in the cast iron turning process. It was shown that using coated tools leads to obtaining a surface qualitatively corresponding to the ground surface and to reducing the power consumption of the machine tool. In addition, the process itself, carried out without a cooling and lubricating liquid, is more eco-friendly, as it excludes its use, disposal and negative environmental impact.

The issue of rubber waste management, among others, due to the intensively developing branch of road transport, and hence a large number of manufactured car tyres, is particularly important for the sustainable development paradigm. Tyres are used not only in internal combustion cars, but also in electric cars, which are considered more ecological. Worn car tyres are not the only type of rubber waste; however, due to the scale of production, they occur most often. The article discusses laws related to this group of waste and methods of its recovery and recycling. All discussed methods of disposal of rubber waste have been characterised in terms of their advantages and disadvantages. An innovative, newly designed pyrolytic installation has also been discussed.
