Background
A modern hospital is a complex,multidisciplinary system which consumesthousands of items for delivery of medicalcare
All these products consumed in the hospitalleave some unusable leftovers
UBC Hospital commissioned a study toanalyze their waste
An 86.6kg sample was collected and handsorted into 24 waste categories (biomedicalwaste not considered)

UBC Hospital waste study
Findings:
1. Composting has thepotential to reduce 41.4% ofwaste
Compostable organics (23.4%): fruitpeels, food scraps and used coffeegrounds
Paper towels (18%): from washroomsand other major hand washing areas
1. Recyclables: plastics(10.8%) and paper (11.2%)
2. Non-recyclable plasticcomprised 0.9% of thewaste stream and garbage
bags comprised 3.8%.3. Medical waste 13.8% .

General waste
Largely composed of domestic orhousehold type waste.
It is non-hazardous to human beings
e.g. kitchen waste, packaging materialpaper, wrappers, plastics
Encourage composting and recycling!

Biomedical waste
Types of waste:
Human anatomical waste
Animal
Microbiology lab
Human blood and body fuild
Sharps
Characterized as:
Biohazardous
Waste that is known or suspected to containinfectious material because of its physical orbiological nature may be harmful to humans,

Biomedical waste
WHMIS standards are not applied to wastematerials but workers need training onhandling and disposing of these wastes
Workers should be properly vaccinated
Hospitals have occupational health and safetypolicies and procedures for accidentalexposures
Treatment and disposal methods arealready outlined in previous lecture notes
Transportation must meet with the TDGRegulations mentioned in the guest lecture

Sharps
Defined as: Waste sharps that are capableof causing punctures or cuts to personhandling it (BC Laws, 2009)
Needles
Syringes
Blades
Laboratory glass
On average, there are 192 injuries per dayfrom sharps in the Canadian healthcaresystem (Becton, Dickinson and Company,2005)

Radioactive waste
Radioactive material used for the diagnosis andtreatment of disease
Two types: sealed sources and unsealed sources.
Sealed sources, usually with long half lives, cannot be accessed as
they are sealed in a capsule or are behind a bonded cover.
Unsealed sources, usually with short half lives, are physically
accessible and are administered to patients, used in research or
testing procedures.
A trained Radiation Officer is responsible for recordkeeping and for the safe use of radio active sources.
The officer ensures instruments are calibrated for
making accurate dose rates and to ensure that the
source is not contaminated.

Radioactive waste
The Atomic Energy Control Board regulates the handlingand disposal of radioactive wastes.
Hospitals have secure on site lead shielded areas where
radioactive isotopes are kept until they are needed or
have decayed to clean waste.
Sealed sources are used many times before being considered as
waste. They are then sent back to the supplier or to another
approved receiver.
Unsealed waste with short half lives, are disposed of as generalwaste after the source has decayed.
All other materials that have come into contact with
radioactive materials, such as towels, gloves, containers,
sharps, are collected together and stored until the
residue has decayed and the items are then disposed of
