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.

ANVISA RDC Resolution no. 306/2004

Provides Technical Regulation for HCW management

Disciplines all stages of HCW management in its intra and extra generator establishment aspects, that is: segregation, conditioning, identification, internal and external collection/transportation, internal

and external storage and final treatment/disposal

Applied to all generators


CONAMA Resolution no. 385/2005

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

dispensation of previous treatment for specific HCW groups

As with sanitary legislation, it presents the classification of HCW in different groups, determined from the characteristics of the waste and the potential risk posed to public health and the environment, which will require specific forms of treatment

and/or final disposal

National Policy on Solid Waste - NPSW (Law no. 12,305/2010)

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)

Prior to NPSW approval, environmental and sanitary legislation in force in relation to HCW management already established the requirement for generators, in operation or to be implanted, to

develop and implant the SWMP



Art. 2, section XI – Medical Waste Management Plan - HCWMP: integral document of the environmental licensing process, based on the principles of non-generation of waste and minimization of waste generation, which outlines and describes actions relative to its handling, within the scope of the services in mentioned in art. 1 of this Resolution, considering aspects in relation to the generation, segregation, conditioning, collection, storage, transportation, recycling, treatment and final disposal, as well as the protection of public health and the environment.

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
