City Centre Biogas Factory and Park, 2012


A biogas factory in the heart of Budapest; normally a function that is supposed to be outside the city limits, but which in fact can have huge benefits for the city and it’s inhabitants, if used in the right way. The main aim was to create a unit, which is as much part of the city, as it is part of the strange hybrid nature of our times.

The proposal aims to create a symbiosis between city, infrastructure and nature. Sewage water is best treated in smaller, decentralized sewage plants to maximize energy gains in the form of biogas. The water is retrieved from the main pipes near on the circular road near Corvin quarter, and led to Markusovszky square, a long derelict, but huge free area in the centre of the city, with a variety of free growing trees. There, water gets treated in wastewater treatment pools, where tropic plants are planted on metal grids, doing the cleaning with their roots and microbes, according to „Organica Water’s” licensed „living-machine” technology. The planthouse-like pools are covered with Etfe membrane, and work as pneumatic structures. Edges of the pools are walls and pedestrian paths at the same time, meandering amid the landscape. Cleaned water gets redirected to the Danube, while wastewater sludge gets into the main building, where digester tanks transform it into biogas, and dewater the neutralized rest. This neutralized rest falls into a huge compost container at the foot of the main building. The resulting earth can be retrieved at the base of the building, falling out on 3 sides. The earth is transported away or used to build the small hills on the square, between the trees;

The building builds its own landscape.

Heated air generated during the process heats the complex, and also through pipes inflates the etfe domes.

The secrets of the inner workings of the unit lure the people to have a looks inside, and ascend to the open loggia on the tree level. There they can enjoy the view with some coffe or wine, chatting about the lates exhibition, while the piano plays.

The main building is one thing, one creature, without windows on the façade; inner processes run fully automatically. The inner „organs” fill it up, while a Y-formed loggia creates a place for the public. The public staircase is at the same time an exhibition space for the biogas process and other energy saving methods, while being of transparent polycarbonate sheets, offer insight into the inner working of the main factory.

The structure holding the inner parts of the building is a transverse row of concrete walls, with holes for the units and free spaces, like ribs. The closed facade is a layer of shot concrete, covered with shot closed-cell-polyurethane for heat and rainwater insulation.
