Waste Management

Introduction and objectives

This guideline is for healthcare agencies dealing with solid waste management. Management of liquid waste and gasses are not included in this guideline.

This guideline has been developed for healthcare services managers, planners, architects, building design professionals, waste officers, regional directors, program managers, senior management, environmental services staff, clinical and non-clinical staff, engineers, user groups and contractors. It will assist in designing sustainable waste management systems and provide guidance for responding to waste management issues in hospitals associated with planning, construction and ongoing waste management systems for handling waste and recyclable materials.

The waste management guideline sets out best practice approaches to on-site waste minimisation and waste management.   The purpose of the waste management guideline is to:

  • encourage efficient building design and establish effective waste management systems in all healthcare developments
  • detail the requirements for handling, storing, collecting and disposing of a range of waste associated with the development
  • minimise waste and collection costs
  • maximise recycling opportunities
  • ensure appropriate separation and storage of waste/recycling healthcare materials
  • ensure on-site waste management systems are well integrated with off-site collection services
  • minimise risk associated with on-site waste management including OHS and infection control.

Obligation for designers:

To allow for proper handling and movement of waste in healthcare facilities the following will need to be considered in terms of space, storage, safety as well as handling of goods and movement of waste management.

Section 28 the Occupational Health and Safety Act 2004 states that:
A person who designs a building or structure or part of a building or structure who knows, or ought reasonably to know, that the building or structure or the part of the building or structure is to be used as a workplace must ensure, so far as is reasonably practicable, that it is designed to be safe and without risks to the health of persons using it as a workplace for a purpose for which it was designed.

Consultation

The Design Team

It is important for hospital designers to discuss the waste management approach within the facility (such as with environmental services staff, contract managers, infection control staff, waste officers and engineers) to determine issues such as:

  • location of waste management equipment including skips and compactors
  • the requirements of waste disposal areas in wards and patient areas
  • size and various types of containers 
  • movement of waste
  • collection and disposal sites.

Technical Guideline

Designing Waste Storage Areas

Space

Sufficient space in the facility areas must be provided for waste containers and equipment as well as waste likely to generate on the premises between collection periods.

When designing waste storage areas in healthcare facilities, designation of the following locations needs to be considered.

Ward/department disposal areas

There is a requirement for sufficient space to be designated within the ward/department disposal area for waste containers and waste generated between collection periods.

Central bulk disposal areas

There is a requirement in the central bulk disposal areas to provide separate designated areas for:
• clean, empty or used waste containers
• secure areas
• temperature-controlled areas
• caged storage areas

Location of Waste Containers

All areas

There is a requirement for all disposal areas to be well located for:

  • convenient disposal for users
  • sited away from food preparation and general storage areas and from routes used by the public
  • safe and efficient movement across the healthcare facility and from disposal area to disposal area such as ward/department disposal area to central bulk disposal area
  • safe and efficient accessibility for collection contractors
  • central bulk central storage areas would be located and designed out of public view from the road, patient and public areas, public walkways, near car parking or adjacent to neighbouring residential/ commercial/educational properties
  • waste/recycling contained in cages, secure or temperature-controlled areas must be placed in a location where collection trucks, or collection person/s permit easy, convenient and safe access.

Design Aspects of Waste Storage Areas

Ward/department disposal areas – point of production

There is a requirement in the ward/departments for secure disposal area sufficient in size to allow for waste to be separated. The ward/department disposal area should provide adequate for space for:

  • containment of waste containers such as wheelie bins for adequate separation of rubbish, recycling and reusable materials including rubbish, recyclable materials, confidential paper, clinical waste and sharps waste during and between collection periods
  • movement of waste materials including manual handling

Central bulk disposal areas

Central bulk disposal areas for should support the following attributes when planning waste storage areas. It should be noted that central storage areas should be sited away from food preparation, storage areas and walkways used by the public.

Clean, empty or used waste container area should be adequately sized to provide enough space for:

  • containment of a variety of empty and used waste containers including wheelie bins, sharps containers and skips for rubbish, recycling, re-use materials including rubbish, recycling, confidential paper and other paper during and between collection periods (this space needs to accommodate all items which are collected from one central location by the waste contractor)
  • equipment including compactors and bailers
  • easy accessibility for cleaning 
  • adequate ventilation to prevent build up of odours
  • clear signage and labelling on all door and entrances
  • spill response kit.

Secure areas should provide enough space for some clinical waste materials such as sharps and cytotoxic waste that require storage in secure areas. These areas should be adequately sized to provide enough space for:

  • containment of used containers including sharps containers and pails for cytotoxic waste to be stored until collection
  • easy accessibility for movement of waste containers
  • easy access for cleaning
  • visual screening from public areas
  • adequate ventilation to prevent build up of odours
  • clear signage and labelling on all door and entrances
  • spill response kit
  • Temperature-controlled areas are required for storing some materials such as clinical waste, clinical waste for incineration only or some related wastes to be stored in a temperature-controlled area. Food waste must also be chilled if not collected within three days of generation. Where waste storage area is temperature controlled, the temperature should be maintained at or below 5-7ºC. These areas should be adequately sized to provide enough space for:
    • adequate ventilation to prevent build-up of odours
    • clear signage and labelling on all door and entrances
    • spill response kit.

Caged storage areas are required for storage of larger items or materials with inherent value such as mattresses, electronic equipment, desks, chairs and office equipment for example. These items must be stored in a caged storage area to reduce the risk of OHS issues arising. These areas should be adequately sized to provide enough space for:

  • adequate ventilation to prevent build up of odours
  • clear signage and labelling on all door and entrances
  • spill response kit.

Other design attributes to consider in central bulk storage areas include the following:

Bin servicing or repair areas should be adequately sized to provide enough space for:

  • containment areas for damaged or new waste containers
  • adequate space for service staff to work with containers to remove and replace wheels and lids safely and without obstruction or OHS issues.

Bin washing facilities must include taps. In addition:

  • the floor surface should be washable with smooth surface and must drain to sewer
  • the concrete floor graded and drained to sewer
  • the area must be undercover to prevent rainwater from entering wash water
  • wash areas are required where waste containers are the responsibility of the facility
  • discharging of wash water must be stated as acceptable on the facilities Trade Waste Agreement.

There is a requirement for all waste disposal areas to consider accessibility and movement of waste containers. Design shall allow for adequate vehicle access, manoeuvring and loading into collection vehicles as well as visual screening from public areas.

Noise
Noise affecting staff, patient, visitors, public and surrounding properties should be considered when choosing location of all waste storage areas.

Lighting
Sufficient lighting must be provided.

Ventilation and odours
• There should be adequate ventilation to prevent build up of odours.
• All disposal areas must have their own extraction ventilation system.
• Mechanical exhaust systems shall comply with AS1668 and not cause any inconveniences, noise or odour problems.

Water supply and hydraulics
A floor waste basket trap connected to the sewer is required within central waste containment areas. A tap facility should also be provided.

Size of Storage Areas

All areas

  • Waste disposal storage areas need to be adequately sized to accommodate the required number of bins, skips, compactors and containment areas. They must be temperature controlled and be flexible in size and layout to cater for future changes of use and growth.
  • The size of disposal areas is to be calculated on the basis of waste generation rates and waste containers. Calculations should be discussed with the collection service providers.

Technical Guidelines

Design of Collection Locations

Site and access to collection locations

Central bulk disposal area

There is a requirement on the site of the facility for providing suitable locations for loading and unloading clean or dirty materials such as used waste containers such as skips, wheelie bins, sharps containers and cardboard. Containers must be placed in a suitably accessible collection location prior to collection-by-collection contractors. Collection points can include, kerbside, driveway or collection dock where collection trucks have access to enter and turn around. It is not acceptable for a truck to reverse out of a site.

  • If bins are to be collected from the kerbside check if there is sufficient room to store all containers for safe collection, for example, check for trees, poles and signs that may obstruct the collection vehicles mechanical pick up arm.
  • The driveway access to the central bulk disposal areas needs to be suitable for collection vehicles in terms of width, strength and design. 
  • The path between waste disposal rooms must be level and free of steps.

Loading docks

There is a requirement for loading docks to be able to facilitate movement of materials in and out of buildings without creating infection-control issues. Loading docks should have the following characteristics:

  • facilitate safe manoeuvring for loading and unloading
  • floor surface should be washable and must drain to sewer
  • positioned appropriately away from food preparation areas, walkways used by the public
  • separation of incoming clean materials and out going dirty materials to prevent cross contamination.

Access

User access and collector access to containers

  • Waste containers in all disposal areas should be clear of obstacles for the user and collector. Waste or recycling containers should not be placed one in front of the other as to restricting access for the user or collector.
  • Disposal areas should be kept closed or locked from public access.

Site access for collection vehicles

Site

  • Collection vehicles need to access waste containers from central bulk storage, temperature controlled, secure waste container storage or loading, collection docks.
  • Access to these areas via service roads wide enough for turning and reversing or driveways should be suitable for heavy loaded collection vehicles.

Access on collection days

All areas

Access to central bulk disposal areas should be free on collection days. There should be no conflicts with other service, collection or delivery vehicles.

Training and Education

Signage/education

All areas

  • All disposal areas should be clearly labelled as ‘Waste Storage Area – Authorised Personnel Only’ on all doors and entrances.
  • Standardised signage on how to use the waste management system and what materials area acceptable into the system must be placed in disposal areas. Signage is available from Department of Human Services and Sustainability Victoria. 
  • All waste containers must be clearly and correctly labelled or coloured to identify which materials are to be placed in which bin.

Other Issues

Safety

  • All storage areas should contain a spill response kit.
  • All mechanical items must comply with OHS requirements.
  • Compactors or mechanical devices used for storage of waste must comply with OHS requirements.

Infection control

  • Bins should be cleaned on a regular basis, internally and externally.
  • Empty ‘clean’ containers should be stored separately to full ‘dirty’ bins to avoid cross contamination.
