Education and training: Key solution to self-management and economic sustainability of waste pickers organisations.

Being a waste picker is not considered a profession in the eyes of society. One reason is that it does not require professional qualifications or training. Thus, most waste pickers are individuals who had difficulty entering the labour market, mainly due to low education levels.

Pollution threat to water and soil quality by dumpsites and non-sanitary landfills in Brazil: A review.

This work presents an overview of environmental studies performed in areas affected by dumpsites and non-sanitary landfills in Brazil, focusing on physicochemical analysis of surface water, groundwater, and soils, as well as geophysical surveys. The objective was to identify the main contaminants found in these areas and to assess their environmental impact, guiding possible intervention measures, indicating the priority areas, and showing whether post-closure activities are mandatory. The results should support governmental actions, especially considering the recent approval of Brazil's new sanitation framework.
