Latitude has collaborated with the Faculty of Architecture La Cambre Horta (Université libre de Bruxelles) to develop a GIS (Geographic Information Systems) based model for waste management commissioned by Bruxelles Environnement to orient Brussels policies on organic waste collection. Organic waste represents the most of regional solid waste which is presently incinerated. The project provides a better understanding of the complex structure of stakeholders that in Brussels are concerned with waste management. Concurrently, it gives spatial characterisation to the generation of organic waste in the Brussels Capital Region. Based on the work of the 1970s by ecologists Duvigneaud and Denayer-De Smet on the biological productivity of green spaces of the region, and through the vectorialisation and land-cover classification of green spaces from contemporary satellite images, the GIS model allows to quantify potential production of organic waste from the various sources identified. The spatial integration of waste management data was useful to feed the debate on separate organic waste collection and valorisation strategies in the framework of a round table organised at the Faculty of Architecture La Cambre Horta in September 2017 with the presence of the research sponsor (Bruxelles Environnement), waste scholars from the Université libre de Bruxelles, and regional organic waste collection and treatment stakeholders (Bruxelles Propreté, WORMS asbl).
