António Guerreiro writes an opinion piece about solid waste treatment, comparing landfills and sanitation complexes to secret places, similar to slaughterhouses. The article draws attention to the fact that these waste treatment facilities remain hidden from public opinion and almost invisible to society.
The author argues that the spaces where waste is treated are kept away from citizens' view, functioning as hidden zones within the urban system. This opacity contrasts with the need for transparency about processes that directly affect the environment and public health.
