Effective waste management is critical to maintaining a high quality of life, but it re-quires both individual and institutional responsibility. The high consumption of goods driven by economic and societal trends necessitates the adoption of new behavioral pat-terns that promote social, economic, and environmental development. Believing that "so-cial responsibility and environmental preservation mean a commitment to life and the fu-ture", in this paper is proposed participatory strategies to awareness the citizens regarding conscious purchasing, prevention, recycling, proper waste disposal, the impacts of waste on public and environmental health. The aim is to increase participation, in an informed way and minimizing environmental and public health impacts of waste management system in Sintra.engEnvironmental education and awarenessUrban waste managementUrban waste recyclingSustainable development goalsSMAS SintraSustainabilityconference object10.1201/9781003345084-49
