HCW MANAGEMENT
The complexity of the HCW requires a joint action by the federal, state and municipal environmental agencies for the environment, healthcare
and urban cleansing, with the aim of regulating its management
Inadequate management of HCW also imposes occupational risks to work environments, as well as to the population in general
HCW MANAGEMENT
1991 - CONAMA Resolution no.06
The incineration or any other burning treatment of solid waste originatingfrom healthcare establishments and transport terminals is waived, and powerhas been invested in state environmental agencies to establish standards andprocedures for the environmental licensing of the collection, transport andconditioning system and final disposal of waste, in states and municipalitiesthat have opted for non-incineration.
In order to minimize these risks, AND preserve public health and the quality of the environment, there is a set of laws, resolutions and standards, issued by official agencies, particularly healthcare and environment agencies, both in the federal sphere and in the state and municipal sphere, which regulate the management of
HCW.

Covers treatment and final disposal of HCW and supplies other provisions
Depending on the characteristics of the waste, determines the respective treatment and/or final disposal methods, including in relation to the

HCW is waste generated in healthcare services, as defined in regulation or in standards established by the agencies of SISNAMA and SNVS (art.13, section I, item g) and establishes that the HCW
generators are subject to the development of a solid waste management plan (Art. 20, section I)

develop and implant the SWMP

Art. 3 Generators of medical waste and the legally responsible agent, referred to in art. 1 of this Resolution, are liable for the management of waste from its generation to its final disposal, in order to comply with environmental and public and occupational health requirements, notwithstanding the several liability of all those natural persons and legal
entities that, directly or indirectly, cause or may cause environmental degradation, particularly transporters and operators of treatment and final disposal facilities, under the
terms of Law no. 6,938 of August 31, 1981.

PANORAMA OF HCW IN BRAZIL
Amount of HCW collected by municipalities - regions and Brazil (ABRELPE, 2012)
Research conducted in 2012 by ABRELPE (Brazilian Association of Public Cleaning and Special Waste Companies) Panorama of Solid Waste in Brazil document
Of the 5,565 Brazilian municipalities, 4,282 provided in 2012, totally or partially, services related to the handling of HCW, resulting in a mean index of 1.5 kg per inhabitant/year. In this research, the survey of the information on HCW collected by the municipalities considered a universe of 401 municipalities interviewed by ABRELPE, with 60% of them being used for the
projection of HCW amounts collected in the regions and for Brazil. The municipalities consulted and used for projection represent 40% of the total urban population of Brazil, indicated by
IBGE (Brazilian Institute of Geography and Statistics) in 2012
Growth of 3% in total collected

PANORAMA OF HCW IN BRAZIL
Research conducted in 2012 by ABRELPE (Brazilian Association of Public Cleaning and Special Waste Companies) Panorama of Solid Waste in Brazil document
ABRELPE stresses that the data presented for the regions and for Brazil should be interpreted and discussed with caution, since the HCW collection carried out by most municipalities is partial, which contributes significantly to the lack of
knowledge about the total amount of HCW generated in Brazil.
Source: http://www.abrelpe.org.br/Panorama/panorama2012.pdf
ABRELPE considers that the majority of Brazilian municipalities only collect and direct HCW generated in public health units, due to the liability assigned to the HCW generators, for the management of such waste from generation to its final
disposal, in effective environmental legislation, CONAMA Resolution no. 358/2005
