Recycling is a process that allows the reuse of waste in the production process. It includes the processing of used materials into new products, so that potentially useful materials are not thrown away, but are used in new production. Recycling is based on a relatively simple principle: waste should be observed as a raw material, which at the same time reduces the need for the use of new natural resources, as well as the amount of waste that needs to be disposed of somewhere. Environmental protection is a set of activities and measures for the prevention of environmental hazards, the occurrence of damage and / or environmental pollution, the reduction and / or elimination of damage to the environment and the return of the environment to the state before the damage occurred. With my final thesis, my aim was to present to the children environmental problems of which they are not yet aware. Through implemented activities I tried to show them the process of paper recycling and how to get new paper without polluting the environment. I conducted the study on a sample of five children as well as their parents. The children are from the middle educational group in Kindergarten "Jelenko" in Osijek. While working with the children, I was convinced that children do have some knowledge regarding waste, and I additionally instructed them regarding the importance of recycling waste. Then, through communication and additional activity with the children, I showed them how they themselves can contribute to the preservation of the environment. I think it is important to state that children in kindergarten should be introduced to the topic of waste at this age, because they acquire good habits from an early age, and therefore learn how to deal with waste as well as paper waste.
