This thesis explores the potential to use factories as sources of water and energy for peri-urban industrian contexts in developing countries. The project is situated in Bandung, Indonesia, on the border wall of a large textile factory surrounded by informal settlements. The project transforms the wall of the factory into a public facility that consists of a public toilet, food market, and factory worker housing. The facility produces energy in the form of biogas, and filters waste water from the toilet for it to be reused by the factory.
