WASTE MANAGEMENTWhat is
Waste? Waste is unwanted or useless materials.
Waste (also known as trash, junk, litter, garbage, refuse, junk and ort.) are materials that are not primary products for which the initial user has no further use in terms of his\her own purposes of production, transformation or consumption, and of which he\she wants to dispose. Residuals recycled or reused at place of generation are excluded.
Waste ManagementWaste management is the collection, transport, processing or disposal, managing and monitoring of waste material.
There are many types of wastes defined by modern systems of waste management,
1.According to their physical form
a. Solid Wastes :b. Liquid wastes:
2. According to their Properties
a. Biodegradable waste :b. Non-Biodegradable waste
3. According to their effect on Human health and the environment
a. Hazardous Wastesb. Non-Hazardous Wastes
4. According to their origin and type
a. Municipal Solid wastes b. Bio-medical wastes: c. Industrial wastes: d. Agricultural wastes:
BIO-MEDICAL WASTE
Definition:
“Bio Medical waste” is any waste, which is generated during the diagnosis, treatment or immunization of human beings or animals or in research activities pertaining to or in the production or testing of biologicals and categories.
Biomedical waste management
Definition:
“Bio Medical waste” is any waste, which is
generated during the diagnosis, treatment
or immunization of human beings or
animals or in research activities pertaining
to or in the production or testing of
biologicals and categories.
Sources of biomedical waste
Biomedical waste is generated in: hospitals, nursing homes, clinics, medical laboratories, blood
banks, animal houses etc. Such a waste can also be generated at home if health care is being provided there to a patient (e.g. injection, dressing material etc.)
Components
Solids: Catheters and tubes
Disposable masks and scrubs
Disposable tools
Medical gloves
Wound dressings
BIOMEDICAL WASTE
Sharps: Blades (Razor or Scalpel)
Material made up glass such
as cuvettes and slides.
Needles
Plastic pipettes and syringes
BIOMEDICAL WASTE
Laboratory waste: Animal carcasses
Hazardous chemicals
Medicinal plants
Radioactive material with
biological components
Supernatants
Radioactive Waste
We will discuss -
Low Level Radioactive Waste
Intermediate Level Radioactive Waste
High Level Radioactive Waste
Radioactive waste are those wastes which contains radioactive material.
Low Level WasteLLW
Low level waste is any waste that could be from a high activity area.
It does not necessarily carry any radioactivity.
Split into four categories: A, B, C, and GTCC.
Intermediate Level WasteILW
Intermediate level waste requires shielding when being handled. Example resins, chemical sludge
Disposal – solidified concrete or bitumen
High Level WasteHLW
High level waste has a large amount of radioactive activity and is thermally hot.
95% of radioactivityCurrent levels of HLW are
increasing about 12,000 metric tons per year.
cntd..
HLW is most dangerous byproduct of nuclear power.
Borosilicate glass most common storage.
Several venues being researched for the safe disposal of HLW.
E-waste.
Any waste that has a circuit board or cathode ray tube (CRT)
Minnesota’s definition includes: Televisions Computers:
central processing units (CPUs), monitors, laptops Computer keyboards, speakers, printers, and
other peripherals VCRs and DVD players Fax machines

Growth of E-waste: Technology Trends
Technological advances speed up obsolescence & lead to more e-waste
PC lifespan falling to estimated 2 years Improved TVs/monitors: HD, LCD, plasma Digital television transition set for

Growth of E-waste: Digital Television Transition
If you use “rabbit ears” or rooftop antenna with an analog TV, you must act. Options:
Buy a converter box to plug into your TVConnect your analog TV to cable, satellite or other pay serviceBuy a TV with a digital tuner
REUSEThis includes conventional reuse where the item is used again for the same function, and new-life reuse where it is used for a new function.
To reuse is to use an item more than once.
RECYCLING MEANS THE PROCESSING OF USED MATERIALS OR WASTE INTO NEW PRODUCT!
RECYCLE
KEY COMPONENT OF MODERN WASTE REDUCTION
&
THE THIRD COMPONENT OF WASTE HIERARCHY
Disposal of waste in a landfill involves burying the waste and this remains a common practice in most countries. Landfills were often established in abandoned or unused quarries, mining voids or borrow pits.

INCINERATION
Incineration is a disposal method in which solid organic wastes are subjected to combustion so as to convert them into residue and gaseous products. This method is useful for disposal of residue of both solid waste management and solid residue from waste water management. This process reduces the volumes of solid waste to 20 to 30 percent of the original volume. Incineration and other high temperature waste treatment systems are sometimes described as "thermal treatment". Incinerators convert waste materials into heat, gas and steam, ash.
WHAT SHOULD BE DONE
Waste Prevention- Reduce office paper waste.
- Economic.
- Recycle.
- Switch to reusable transport containers.
WHAT SHOULD BE DONE
Donate/Exchange
- old books
- old clothes
- old computers
- excess building materials
- old equipment to local organizations
WHAT SHOULD BE DONE
Employee Education
- Develop an “office recycling procedures” packet.
- Send out recycling reminders to all employees including environmental articles.
- Train employees on recycling practices prior to implementing recycling programs.
