Waste Management | Hazardous Waste Management

1. WASTE
MANAGEMENT

2. OBJECTIVES
Upon completion of the lesson, participants will be able to:
• List of various types of wastes generated on construct site
• Define hazardous & non hazardous wastes & give example
of each
• Identify the best means to manage waste in sit
• Identify precautions taken while handling wastes on site
• Identify whose role to reduce waste

3. WASTE CLASSIFICATION
There are 3 classes of waste as follows:
Class I: Hazardous Waste
Non Hazardous Waste: can be classified as:
Class II: Biodegradable or Chemical Decomposable
Waste
Class III: Inert Waste

4. Hazardous Waste (Class I)
➢ All hazardous wastes are defined as Class I:
they are classified as those, which constitute a
high degree of hazard for public health and
the environment.
➢ Hazardous waste includes, those
materials, which are ignitable,
corrosive, reactive, toxic or
radioactive.

5. HAZARDOUS WASTE (CLASS I)
Hazardous Wastes include:
Oily rags and used absorbent pads
Fluorescent lamps
Cement
Waste oil and oil filters
Paints and coating cans
Used batteries
Soil contaminated with Oil or Diesel
Glycol and Anti-freeze
Unused, spent or expired chemicals

6. NON HAZARDOUS WASTE
Class II: Biodegradable or Chemical Decomposable
Waste
Decomposable waste (Class II) - Non-hazardous solids and
sludge which are biologically or chemically reactive in the
natural environment such as paper, wood, household
garbage, some metals, animal wastes and digested sewage
sludge.
Class III: Inert Waste
Inert waste (Class III) - Wastes which are not biologically or
chemically active in the natural environment. Examples
include glass, concrete and brick materials, broken clay and
chinaware, most plastics and manufactured rubber products

7. NON HAZARDOUS WASTE
Non Hazardous Wastes include:
Unwanted food
Plastic including empty water bottles
Cardboard including cigarette packets
Paper
Rags
Glass
Scrap metal
Grit blast
Packaging
Timber

8. WASTE MANAGEMENT
Waste Management is the act of keeping the working
environment cleared of all unnecessary waste and
materials.
At first, the amount of unnecessary waste produced must
be minimized based on the following strategy :
Reduce
Reuse
Recycle

9. HAZARDOUS WASTE MANAGEMENT
After identifying the Sources of Hazardous Wastes on the
Project, Hazardous Waste Management consists of the
following steps:
Segregation
Collection
Storage
Transport
Final Disposal

10. HAZARDOUS WASTE MANAGEMENT
SEGREGATION
Hazardous wastes will be segregated into the following
categories:
Waste chemicals
Waste lubricants
Oily sand
Tank & other sludge
Batteries
Tires
Oil drums (empty)
Clinical waste
Other waste

11. HAZARDOUS WASTE MANAGEMENT
COLLECTION
Clinical waste will be collected from the site medical
facilities and from the mobile first aid units on daily
basis.
Waste chemicals and lubricants will be collected in
compliance with the suggestions and
recommendations of the specific Material Safety Data
Sheets (MSDS).

12. HAZARDOUS WASTE MANAGEMENT
STORAGE
Hazardous waste material shall be stored in a separate storage
area.
The area shall have an impervious surface with a suitable
drainage control, roofing and be appropriately bunded.
Quantities stored shall be kept to an absolute minimum.
Containers shall be marked with warning labels to accurately
describe their contents.

13. HAZARDOUS WASTE MANAGEMENT
STORAGE (CONT.)
Hazardous chemicals shall be stored and handled in
accordance with the Manufacturer’s Material Safety
Data Sheet (MSDS) or as per the Client’s or Local
Regulatory Authority Requirements.
CCC shall have readily available all the relevant MSDS at
the Chemical Storage Area and the location where
chemicals are being used.

14. HAZARDOUS WASTE MANAGEMENT
TRANSPORT
The hazardous waste will be transported in the in
designated vehicles to the proper disposal locations.
The vehicles shall be marked “Hazardous Wastes –
Improper Disposal Prohibited”.
The driver will be provided with copies of the MSDS
relevant to the material he is transporting in the
vehicle.
The driver shall also have a copy of the waste log which
will indicate source of waste,type of waste,quantity,
disposal method and location and date and time.

15. HAZARDOUS WASTE MANAGEMENT
FINAL DISPOSAL
Hazardous waste (Class I) shall not be disposed of
directly to the municipal landfill;
Hazardous waste will be disposed off at designated
hazardous waste disposal area.

16. NON HAZARDOUS WASTE
MANAGEMENT
After identifying the Sources of Non Hazardous Wastes on
the Project, Non Hazardous Waste Management consists
of the following steps:
Segregation
Collection
Storage
Transport
Final Disposal

17. NON HAZARDOUS WASTE MANAGEMENT
SOURCES
The sources of Non Hazardous wastes that will be
generated on the Project are:
Domestic Wastes
Construction Wastes

18. NON HAZARDOUS WASTE MANAGEMENT
SEGREGATION
Non Hazardous Wastes will be segregated into the
following categories:
Combustible solid waste
Non-combustible solid waste
Recyclable solid waste/Reusable solid waste

19. NON HAZARDOUS WASTE MANAGEMENT
COLLECTION
• The waste will be collected as it
accumulates or at the end of the days
work or as necessary and will be stored in
specific containers.
• Non-combustible waste will be collected
in temporary skips/containers pending
transport to the designated disposal area.
• Combustible waste will not be allowed to
accumulate.

20. NON HAZARDOUS WASTE MANAGEMENT
STORAGE
Solid wastes shall be temporarily stored such that they will not
constitute a fire, health, safety or environmental hazard or
be accessible to animals and carrier animals.
Waste storage area shall be provided with a seal between the
stored waste and underlying surface layers
There shall be adequate control of wind blown materials,
pests, odors etc.
Non-combustibles are to be placed in plastic bags and
disposed of into designated skips/containers

21. NON HAZARDOUS WASTE MANAGEMENT
TRANSPORT
Vehicles delivering waste to the disposal area shall be
covered and maintained so as to prevent dripping,
leaking, or blowing of solid waste from the vehicle.

22. NON HAZARDOUS WASTE MANAGEMENT
FINAL DISPOSAL
All combustible waste will be delivered to the designated
burning facility.
Solid wastes and suitably de-watered semi-solids and
sludge (Class 2 & 3 materials) will be disposed of in a
sanitary landfill or as stipulated in the Local
Regulatory Authority Requirements.
Non-combustible material will be disposed of as follows:
All domestic non-combustible material will be disposed of in the
designated disposal area.
All construction non-combustible waste will be disposed of in
the designated disposal area.

23. RECYCLABLE MATERIAL
If the Recyclable facilities are not
available for recycling then the waste
will be segregated for its
combustibility versus non-
combustibility
If the facilities are available for recycling,
then the recyclable waste will be
segregated according to the types and
locations of recycling facilities in the
area.

24. WASTEWATER MANAGEMENT
Sources of Wastewater
Salty Waters “construction water” excessive sediment
loss
Hydrostatic test water
Liquid (Raw) sewage from the camp, canteen and
construction yard.
Collection
Liquids shall be collected in tanks or (lined)
ponds
Sanitary effluents shall be collected in a septic
tank or equivalent system or available sewage
system.
All liquids will be disposed of according to the
Local Regulatory Authorities Requirements.

25. WASTEWATER MANAGEMENT (CONT.)
Storage
Raw sewage produced will be collected in septic tanks and will be
trucked to the central treating facilities.
Liquid storage container: spills and leaking of containers can cause
contamination of groundwater.
Treatment
A sewage treatment plant will be installed in order to treat waste
water generated from the project.
Solid sludge (digested sludge only) shall be transported to the final
disposal site or shall be used as fertilizer.
Disposal
The wastewater that is treated will meet the requirements for
Agricultural reuse for purposes of irrigation and in accordance
with the Local Regulatory Authority Environmental
requirements.

30. WHY TO MANAGE WASTE?
Polluting the Environment affects the
Ecosystem we are living in.
Uncontrolled wastes is a source of
dangerous diseases and affects badly
our health.
Uncontrolled wastes bring snakes,
dogs, rats,insects and others.
Uncontrolled wastes look and
smell very bad.

31. WHAT TO DO IF:
I don’t know if a waste is considered domestic or
hazardous?
there are no skips at site?
the skip is full?
there is no label on the skip or you cannot read the label?
my crew / supervisor doesn’t care about waste?
