In September 2011 Sustainable Sweden Association had the great and first pleasure to welcome a group of Chileans. This Tour was part of a cooperation project that started 2 years ago between Chile and Sweden and which aim is to create eco-municipalities in Chile modeled on the “ekokommun 5.0” concept developed in Sweden by Torbjörn Lahti. Therefore the visits and the workshops have been focused on Chilean communes challenges towards sustainability, such as waste management, renewable energy, biogas and green buildings.
