The worker cooperative Creando Conciencia (Creating Awareness) was born in the year 2005 in Argentina, upon the initiative of a group of neighbours greatly worried about the final disposal of urban solid waste, the problem of urban garbage collectors ("cartoneros") and the possibility of generating alternatives that could address these problems with social responsibility and sustainability. Based on such concerns, the group began to think about the possibility of designing the process of differentiated waste collection in their own neighbourhoods.
