News and Topical issue. How has waste production changed in Slovakia since the beginning of the coronavirus crisis and where should we throw away, for example, a polystyrene single-use lunch box? We asked Martin Maslák, chairperson of the Board of Directors of Bratislava solid waste management company. Did you know that up to 45% of our regular waste is composed of bio-waste that could be used in compost? In our second interview, Eliška Behalková from the CUKETA civic association will explain how to create your own vermicomposter. And, in the third part of our programme, zoologist Karolína Sobeková will tell us more about the importance of river channels and the Danube inland delta full of diverse forms of life.
