1
What is Disaster Waste ?
Abnormal generation of waste
resulting from a natural disaster
or conflict
3
Types of Disaster Waste
•
•
•
•
•
•
•
•
Sediment, soil and vegetation
Hazardous wastes
Building debris
Household possessions
Relief waste such as packaging
Unexploded ordnance and military vehicles
Healthcare waste
Waste from:
– internally displaced people [IDP] camps
– relief workers accommodation
– host community / municipal waste

Different Disasters
Different disasters are likely to generate different
types of waste:
•Tsunami: Vegetation, human and animal remains, building
debris, municipal, camp and from relief operations
•Earthquake: building debris, healthcare
•Floods: households goods, healthcare, animal carcasses, camp
•Hurricanes/Typhoons: similar to floods + building debris and
vegetation
•Post-conflict: destroyed buildings, military hardware,
unexploded ordnance (UXO), depleted uranium (DU), camp and
from relief operations
DW1

Why is Waste Management Important ?
• Protect public health
• Protect environment and reduce
risks
• Opportunity for saving costs /
income generation
• Support sustainable livelihoods
• Ensure all wastes and necessary
approvals covered
• Reduce future risks and liabilities
• Ensure proper Health & Safety for
workers
DW1
6
Managing Disaster Waste
• Waste management is a multiple cluster and
cross-sector issue – health, construction,
municipal services, financial, industry, tourism.
• Important that all stakeholders have an
appreciation of waste threats and challenges
but also of opportunities.

7
Managing Disaster Waste
• When planning for camp and host community
general and household waste ensure:
• All stakeholders are involved to ensure cultural and
social norms specific to the context are considered.
• Work is closely coordinated with Community
Mobilisers / Public Health Promotion staff for effective
information collection & dissemination
• Beneficiaries are involved in collection and
maintenance activities from the beginning

HAZARDOUS WASTE
Waste is hazardous when it contains properties that might
make it harmful to our health or the environment
DW1

13
Main Components of Hazard Waste
Engine Oil – Waste Oil
Asbestos
Batteries
Oil Contaminated Soil
Health Care Waste
Fertilizer & Pesticides

ASBESTOS: Definition
Asbestos is a naturally occurring mineral that
has been in use on a commercial scale for about
150 years
•Ideal for:
o Fireproofing
o Insulating material
•Hazardous to human health if inhaled
o fibres enter lungs
Asbestos Fibre
DW1
15
ASBESTOS: Common Uses
The major uses for asbestos materials in
buildings are:
Sprayed asbestos and lagging
Asbestos cement
Asbestos insulating board
DW1
16
What is Health Care Waste ?
WHO:
All waste from a health care facility that
includes both potential infectious waste
and non-infectious waste materials
DW1
17
Infectious Health Care Waste
WHO:
• Infectious sharps: syringes or other
needles, blades, infusion sets, broken
glass or other items that can cause direct
injury
• Infectious non-sharps: materials that have
been in contact with human blood or its
derivatives
DW1
18
Infectious Health Care Waste
• bandages, swabs or items soaked with blood
• isolation wastes from highly infectious
patients - including food residues
• used and obsolete vaccine vials
• bedding and other contaminated materials
infected with human pathogens
• Human excreta from patients are also
included in this category
DW1
19
What is Not Infectious
Health Care Waste ?
• materials that have not been in
contact with patients such as paper
and plastic packaging, metal, glass
or other wastes - similar to
household wastes.
DW1
20
What is Debris ?
• Clean Rubble
o
o
o
o
o
o
o
o
o
• Hazardous Materials
o Asbestos
o Heavy metals (i.e. lead
in piping)
o Paint
o Adhesives
o Contaminated soil, etc.
o Can contaminate the
whole waste stream
Concrete
Bricks
Rocks
Wood
Plaster
Metal
Paper
Plastic
Tiles
Rubble for recovery needs to be clean of contaminants and
hazardous materials
DW1
21
Mixed Rubble
Mixed Rubble cannot be readily recovered and will require
additional work to segregate such items as timber, plastics etc.:
Timber
Plastics
Furnishings
DW1
22
Sources of Rubble
 Rubble clean-up
 Demolition of buildings
 Repair of buildings
 Demolition of bridges
 Rehabilitation of roads
 Construction waste

•
Removal of rubble provides access for Search & Rescue
•
Removal of waste reduces public health risks
•
Identification and proper handling of hazardous waste protects
communities from health risks
•
Waste factors in Rapid Environmental Assessments
•
Recycling of waste materials supports economic recovery
•
Recycling of rubble provides building materials for shelter
programmes
•
Set foundation for normalising ensuing municipal solid waste
management
•
Capturing knowledge, data and information during disaster waste
response can feed into future disaster preparedness planning

Threats: Environment
Local Environmental Risks:
• Waste – directly contaminates soils (chemicals and
micro-organisms)
• Leachate – contaminates surface, ground and marine
waters, results in stress and/or algal blooms
(eutrophication)
• Landfill gas – dieback of vegetation
• Biodiversity - rodent, insect infestation
• Aesthetics – wind and wave blown litter
Source: UNEP “Tsunami Waste Management Plan” Workshops 2005
DW1
31
Threats: Reconstruction and Livelihoods
•
Impedes vehicle, marine and pedestrian access
•
Blocks drains/gullies/wells
•
Dumping of waste in low-lying agricultural areas (rice paddies) and fishfarming ponds
•
Serves as a constant reminder of
the disaster
•
Acts as magnet for ongoing flytipping
•
Precludes livelihood recovery
•
Harbour and channel blockages
prevent resumption of fishing
activities and restricts river and
marine transport

Opportunities
• Valuable Resource Material (coral blocks,
concrete, mortar, steel, electrical cable and
equipment)
• Recycling of demolition waste
• Disaster preparedness
• Composting
• Improved waste management
• Economic development
DW1
33
Economic Development
• Source of income for IDP’s/unemployed
• Direct “cash for work” projects
• supply of equipment
• sale of recycled products
• Trained workers for the implementation of long-term WM
systems
• Revenue-generation schemes linked to long-term sustainable
WM systems including:
1. Collection and disposal charges
2. Fiscal policy – import duty on aggregates/plastic bottles, landfill
tax
3. Promotion – composting, glass bottle
return
schemes,
