3G LITCHED LANDFILL

TFM / ETSAV-UPC / 2022 / Barcelona

Theinitial intuitions of the project were related to those landscapes where natural and human agents are in conflict, La Pedrera Vallsallent is an abandoned limestone quarry, proposed as a landfill. A landfill of inerts is nothing more than a cemetery of architectures, the effect of our architecture causes the need to find spaces to “bury” it, a process currently not considered at all when carrying out a project. The aim is to give a second life to these “dead architectures”, and since the landfill is going to be carried out, it is proposed to design it, organizing it by phases generating voids in the interior.

The recycling line of a landfill separates and shreds the waste, obtaining different granulometries and storing them in piles. The concept of “heap”, whether of waste, sand... is understood as the static form and in equilibrium that a heap of units of the same “element” reaches when they are dumped from above. Depending on its materiality, texture, adherence, humidity... this heap will have a more or less slender proportion in equilibrium.

Fines will be poured first and will be moistened depending on the slenderness of the desired “pile”. The aggregates will be mixed with lime, forming a conglomerate poured on top of the fines. Once it has dried, the fines will be extracted, generating an empty space with the shape of the “piles” of fines, a form that is structurally stable by nature.
