ABSTRACT In an era of rapid change and global challenges, impactful educational experiences about sustainability become imperative. Especially in organic waste conversion bioprocess such as anaerobic digestion (AD). Here proposed, is a gamified approach to learn AD and hidden microbial interactions, bringing to real-life size an invisible phenomenon. In Methan-o-poly, participants roleplay cooperating microbes within a bioreactor engaged in four sequential mini-games to mimic organic waste degradation and methane production. Perturbations in the activity simulate real challenges, enhancing adaptability and problem-solving skills. Overall, this cooperative game promotes motivation, collaboration, and experiential learning. Its initial implementation received positive feedback across various age groups, enhancing green education initiatives.
