This articlepresents an update ofthescenarioof CDW recycling in Brazil between 1986 and 2008, presentedby Miranda et al. (2009), withupdatesuntil 2020. The compilationofdata was carried out throughaccesstoscientificliterature, standards and based on theSectorial Surveys ofthe Brazilian Associationfor Recycling ofCivil Construction and Demolition Waste (ABRECON). The CDW recyclingactivity in Brazil started in the 80's, withweakgrowthuntiltheendofthe 90's. In 2002 therewerefew CDW recycling plants installed in thecountry. As ofthisyear, withthepublicationof CONAMA Resolution nº 307, a slightincrease in thegrowth rate ofthesefacilities was noticed. Withtheheatingofthesectorbetween 2007 and 2013 and theapprovaloftheBrazilian National Policy on Solid Waste (PNRS), therecyclingof CDW intensified. Even so, thedistributionof plants in the national territoryisquiteuneven, withthehighestconcentration in theSoutheastregion.
