The NGO “Zeleni Sad” has successfully completed the implementation of the Eco-coloring book project, supported by the City Administration for Environmental Protection of Novi Sad. During the project, cooperation with kindergartens and over 400 children was established. The children had the opportunity to first come up with the concept of RECYCLING and learn that the reuse of waste provides a healthy environment and saves natural resources. In a creative way, they have learned that there are different types of waste and that it does not go together into the same bin, but is sorted into bins of different colors depending on the material of which the product is made. Through this project we have contributed to raising awareness of the environment, its protection and sustainability among the youngest.
