In the classrooms of Diósgyőr High School, we selectively collect PET bottles and ALU cans. We do the selective collection a little differently within the framework of the campaign. Students often throw the bottles not in the selective bin, but among the other garbage, even though they could exchange them for 50 HUF. We encourage students to selectively collect by exchanging the bottles thrown into the bags and using the proceeds for charity. We donate the entire amount to an animal shelter.
