The concept of sustainable development arises because of concerns about the accelerated deterioration of environmental conditions caused by behavior that only aims to meet needs without considering the negative impact on the environment in the future. One of them is the waste management system which is still carried out with the collect-transport-disposal system. To prevent the negative impacts of waste that are increasing all the time, such as the emergence of vectors, odors, and smoke due to combustion, a better way of waste management is needed, namely reducing waste through reduce, reuse, and recycle (3R). Through fostering students' eco-literacy about the importance of the 3Rs, it is hoped that there will be a change in students' mindset from an early age to prevent future environmental crises and a behavioral transition to a sustainable lifestyle, especially those who are accustomed to reducing waste. The purpose of this activity is to increase school commitment and student behavior to get used to the 3Rs in everyday life. This activity was carried out at SDN 08 Koto Gadang, District IV Koto, Agam Regency, in the form of counseling, 3R leaflets, and the provision of separate trash bins between organic, paper, and plastic. Pre-test and post-test activities were carried out to assess changes in students' knowledge about the extension material provided. This activity indicates an increase in students' knowledge about reducing, reuse, and recycle. It is hoped that schools can take advantage of the trash bins provided so that all school residents can dispose of waste according to its type so that the remaining waste is easier to process in subsequent handling.
