Nowadays, many Croatian citizens do not demonstrate consciousness for waste disposal which is one of the biggest ecological problems of contemporary time. Inadequate waste disposla effects the environment, human health and quality of life. Massive amounts of waste are produced daily and such waste should be disposed in an adequate way. This paper will research all the procedures of adequate waste disposal and try to encourage citizens to manage waste properly through posters. Concept designs of posters will be different in color, typography and motifs to convey the proper message through different visual aids. In order to better adjust the visual appearance to the broad population, an online survey will be conducted. It will contain two options for poster design and it will test out which priniciples of design appeal best to the surveyed group. It will also explore consciousness and attitudes of people about the consequences of poor waste disposal. The goal of the paper is to provide an insight into different design aspects that appeal more to a certain group. It will also demonstrate a poster that was chosen through the survey as the final design and the poster that should encourage people to properly dispose of waste in the best possible way and also to preserve the environment and future of their country and city.
