An environmental action initiative with the motto ‘Waste Less, Treasure More’. It focuses on reducing food waste, repurposing organic waste and working with municipalities, schools and the public to reshape behaviour around the reuse of ‘waste’. The project involves scientific research, public engagement, advocacy and participatory education by a team of educators and scientists. A central aspect of the project is cultivating ‘The Urban Shell’; FoodTreasure conducts practical research on the possibilities of easily replicable composting techniques (for small gardens, balconies, municipalities etc) in urban and peri-urban Mediterranean settings.
