the first place winner proposes an enormous, vertical waste treatment plant that produces methane for energy. designer marko dragicevic of serbia elaborates: ?the towers are module-based, and every tower is consisted of waste capsules that are attached to the concrete core. firstly, city waste is being delivered to sorting facility, where it is categorized by type (glass, plastic, organic matter, paper, wood, metal), after which it is sent to temporary landfill. the recyclable waste is taken to recycling facility, and organic matter, parts of wood and paper materials are gathered and disposed into modular waste capsules. these capsules are attached to the tower core by cranes. every capsule is equipped with inhaler and pipeline that connects to the methane tank, and when organic matter rots, methane produced by the process is drawn from each capsule and later transformed into energy.?
