Nanning Waste-to-Energy Power Plant is located on northwestern outskirts of Nanning. Backed by undulating karst mountains, the site is inspirational for its natural context. The main façade of the factory building is 200 meters wide and 55 meters high, aligning with a mountain col to the north of the site. Beyond the col, there is a plateau flattened by the mining of a cement plant. Given the perspective effect between near and far, the volume of the factory building is close to that of the background mountains. In order to respond to the natural environment and the memory of the site, the main facade of the building is featured by a pattern of undulating mountain range to visually remedy the damage to the maintains by human impacts, evoking the self-examination of human activities.
