ACTIVE EDGE MANIFESTOActive Edge is a radical strategy that specifically addresses the unitary dimension (spatial and biological) characterizing every landfill, retracing it in order to visualize and nurture its presence;Active Edge undestands such residual places as potential autopoietic systems: urban organisms able to constantly (re)produce their own components and relative network of processes;Active Edge focuses on the landfill’s border to generate a space of friction (denser exchange) which filters external energies (people, water, watts) through a self-contained and artificial landscape;Active Edge programs the complex of liminal activities in terms of dichotomies: research/waste collection (west, with the EcoDesign center and collection facilities), leisure/water treatment (south, spa and wellness center), leisure/landscape (north and east, new double layered parking and look-out tower);Active Edge moulds three inner landscapes to control planting and stormwater while implementing the use of the edge: cultivation-composting (west, the productive landscape), education (baricenter, the educational landscape), reforestation (east);Active Edge is both programmatic cause and visible effect of understanding the autopoietic landfill-organism (at the bottom space of cities): it won’t be possible to ignore it, it would be absurd not to learn from it.
