3. Waste according to Regulation of Exports and Imports
Act 1989, if possess these characteristics then termed as
Hazardous Waste
•Explosive
•Flammable Liquids/Solids
•Poisonous
•Toxic
•Ecotoxic
•Infectious substances.
Introduction

4. •Asbestos
•chemicals for e.g. brake fluid or print
toner
•batteries
•solvents
•pesticides
•oils (except edible ones) for e.g. car oil
•equipment containing ozone depleting
substances for e.g. fridges
Examples of Hazardous Waste

5. Types of Waste
Listed waste
Characteristic
waste
Universal waste
Mixed waste

6. Wastes that EPA has determined are hazardous. The
lists includes the
• F-list (wastes from common manufacturing and
industrial processes)
•K-list (wastes from specific industries)
• P- and U-lists (wastes from commercial chemical
products).
Listed Waste

7. •This list identifies wastes from common manufacturing and
industrial processes
•such as solvents that have been used in cleaning or degreasing
operations. Because the processes producing these wastes can
occur in different sectors of industry,
• the F-listed wastes are known as wastes from non-specific
sources.
The F-list Waste

8. •This list includes certain wastes from specific industries,
such as petroleum refining or pesticide manufacturing.
•Certain sludges and wastewaters from treatment and
production processes
• These industries are examples of source-specific wastes
The K-list Wastes

9. •These lists include specific commercial chemical products in an
unused form.
•Some pesticides and some pharmaceutical products become
hazardous waste when discarded.
•These are also termed as discarded commercial chemical
products.
The P-list and the U-list

10. CHARACTERISTIC
WASTES:
The waste exhibiting these characteristics is
termed as characteristic waste
 Ignitability
 Corrosivity
 Reactivity
 Toxicity

11. Following discarded substances are termed as
Universal waste
•Batteries,
•pesticides,
•mercury-containing equipment (e.g., thermostats)
• lamps (e.g., fluorescent bulbs).
UNIVERSAL WASTES

12. Mixed waste contain radioactive as well as other hazardous
components
•Two acts are dealing with mixed waste management
1. RCRA (Resource Conservation and Recovery Act )
2. AEA (Atomic Energy Act)
MIXED WASTES

13. •The collection, treatment, and disposal of waste material
that when improperly handled can cause substantial harm
to human health and safety or to the environment.
•Hazardous wastes can take the form of solids, liquids,
sludge’s, or contained gases
•They are generated primarily by chemical production,
manufacturing, and other industrial activities.
HAZARDOUS WASTE
MANAGEMENT

14. They may cause damage during
inadequate
•Storage
•Transportation
• treatment
•disposal operations.
HAZARDOUS WASTE
MANAGEMENT

15. •Improper hazardous-waste storage or disposal
frequently contaminates surface and groundwater
supplies.
•People living in homes built near old and abandoned
waste disposal sites may be in a particularly vulnerable
position.
• In an effort to remedy existing problems and to prevent
future harm from hazardous wastes, governments closely
regulate the practice of hazardous-waste management.
EFFECTS OF INAPPROPRIATE
MANAGEMENT

17. STORAGE AND HANDLING

18.  Hazardous materials are not disposed off down the drain or in regular trash
receptacles.
 They are put into proper and compatible containers that can be securely sealed.
Compatible container materials ensure that wastes will not react with or corrode
them.
 The containers are not completely filled; a “head space” allows for waste
expansion.
 The sealed containers are labeled with the name and hazard class of the waste
along with the words ‘Hazardous Waste’ and the date it was generated.
STORAGE AND HANDLING

19.  Waste containers are stored in a secure manner and protected from
extreme environments.
 They are segregated and stored in compatible hazard classes (flammable,
Explosive, corrosive, Toxic or oxidizers, etc.) to prevent hazardous reactions
if the wastes combine.
 The containers are closed during storage, except when adding or removing
waste.
 Proper handling and storage of waste containers can prevent ruptures,
overturns, or other failures.
STORAGE AND HANDLING

20.  They should not be stacked or handled in a manner that could cause
them to fail.
 Some flammable material containers may require grounding and
containers should be seismically secured, if possible, to prevent spills in
an earthquake.
 Waste storage time limits vary depending on the facility or material.
STORAGE AND HANDLING

21.  Hazardous Waste Characterization Scoping Study
 Hazardous Waste Identification Studies – Solvents and
Selected Petroleum Refining Residuals
 Report to Congress on RCRA Hazardous Waste
Identification of Methamphetamine Production Process
By-products
WASTE IDENTIFICATION PROCESS

22. •According to some environmentalists in the ministry, Pakistan has
become the dumping ground for hazardous waste such as hospital
waste, e-waste and many kinds of used oils.
•major dumping cities are Karachi, Gujranwala and Faisalabad etc.
STATUS OF HAZARDOUS
WASTE MANAGEMENT IN
MEDIA

23. •But what really worried environmentalists with the ministry were
unabated imports of arsenic substances and materials.
•Imports of all kinds of arsenic substances are banned in Pakistan.
But they are still imported under different trade names.
•Arsenic trisulphate is one example extensively used in Unani
medicines. Importers avoid using generic names that would
otherwise alert customs.
STATUS OF HAZARDOUS
WASTE MANAGEMENT IN
MEDIA

24. •The ministry maintained no database on
importers and how hazardous wastes were
handled once it landed in the country.
•There is no monitoring mechanism to visit
sites where importers dumped dangerous
waste. It depends on provincial
Environmental Protection Agency’s (EPA) to
keep a watchful eye.
STATUS OF HAZARDOUS
WASTE MANAGEMENT IN
MEDIA

25. •Pakistan restricts the export of hazardous
wastes and other wastes for final disposal.
•The amendment to the Basel Convention has
not been implemented in Pakistan.
STATUS OF LAW OF HAZARDOUS
WASTE IN PAKISTAN

26. According to Section 14 (Handling of Hazardous Substances)
of Pakistan Environmental Protection Act - 1997 "subject to
the provisions of this Act, no person shall generate, collect,
consign, transport, treat, dispose of, store, handle or import
any hazardous substance except;
(a) under a license issued by the Federal Agency and in such
manner as may be prescribed; or
(b) in accordance with the provisions of any other law for
the time being in force, or of any international treaty,
convention, protocol, code, standard, agreement or other
instrument to which Pakistan is a party.
STATUS OF LAW OF
HAZARDOUS WASTE
IN PAKISTAN

27. So Pakistan is restricting import
of hazardous waste under the
Pakistan Environmental
Protection Act 1997

28. •raising awareness about consequences caused by
solid waste pollution, role of government sector,
NGO’s, Private sector collectively for solid waste
management
•legislation should be done which would be
effective and find ways to implement it effectively
•application of 3R’s (Reduce, Recycle and Reuse)
concept in solid waste management.
Conclusion and
Recommendations

29. •House to house collection of solid waste should be organized.
•Littering of solid waste should be prohibited in cities, towns and
urban areas.
•Proper segregation would be vital for scientific disposal of waste.
•Developing legal framework and national guidelines for solid waste
management that includes waste management rules and basic
recycling rules.
Conclusion and
Recommendations
