The aim of the project is to educate citizens on how to prevent the spread of the tiger mosquito. Residents of the City of Ljubljana are invited to events to which they can bring old ceramic, plastic or metal containers. In exchange they receive different plants which repel tiger mosquitos and high-quality compost produced in RCERO Ljubljana from separately collected biological waste. Gathered containers planted with plants are used for making public spaces greener and are distributed among the visitors of our events.
