It especially makes its mark on the business unit Environmental Technology with smart waste disposal technology. What is still an individual solution in Germany is already standard in Italy: entire municipalities handle refuse disposal with a so-called e-Gate waste lock made by emz. By recording the volume of each refuse unit thrown in, the costs for waste disposal are recorded fairly for each consumer and invoiced automatically to the person concerned. This not only means considerable potential savings for individuals, but is also an incentive to separate waste systematically.
