2. Waste
Non-liquid, non-soluble materials ranging from municipal
garbage to industrial wastes that contain complex and
sometimes hazardous substances.
Solid wastes also include sewage sludge, agricultural
refuse, demolition wastes, and mining residues.
Technically, solid waste also refers to liquids and gases in
containers

4. Waste: Any material that is discarded, served its
intended purpose, or is a manufacturing or mining
byproduct
Solid Waste: Everything not covered by the Clean Air
and Water Acts, including solids, liquids and gases
(RCRA is a catch all)
What is Solid Waste
5. Solid waste means any garbage, refuse, sludge from a
wastewater treatment plant, water supply treatment plant,
or air pollution control facility and other discarded
materials including solid, liquid, semi-solid, or contained
gaseous material, resulting from industrial, commercial,
mining and agricultural operations, and from community
activities
6. Solid wastes are any discarded (abandoned or
considered waste-like) materials. Solid wastes can be
solid, liquid, semi-solid or containerized gaseous
material.

9. Environmentally acceptable disposal of waste on ground.
Sanitary landfills are where non-hazardous waste is spread in
layers, compacted, and covered with earth at the end of
each working day. Secure landfills are those where hazardous
waste is disposed of by burial, in holes or trenches in ground
lined with impervious plastic sheeting to prevent leakage
or leaching of dangerous substances into soil and
water supply.
What is Landfill
14. Protect human health and the environment from the
potential hazards of waste disposal
Conserve energy and natural resources
Reduce the amount of waste generated
Ensure that wastes are managed in an environmentally
sound manner
Resource Conservation and Recovery Act
15. Hazardous Waste: manages hazardous waste from the time
it is generated until it is disposed (referred to as cradle to
grave)
Solid Waste: sets criteria for municipal solid waste and
other non-hazardous waste disposal facilities and prohibits
open dumping of solid waste
Underground Storage Tank: regulates underground storage
tanks storing petroleum or other hazardous substances
17. Waste Management and Remediation Division is
responsible for monitoring and controlling the
generation, treatment, storage, and disposal of
wastes. On the remediation side, program resources
are directed to responding to releases of hazardous
substances to surface waters, ground water, or soils.
Waste Management & Remediation
18. Waste remediation is a process in which contaminants are
removed or neutralized so that they cannot cause harm. It
may entail actively removing the waste, which is generally
preferable, or isolating or containing the waste on-site
because it too costly or impractical to remove.

19. Light Weighting
The process of reducing the amount of a particular
material per unit of product is known as light
weighting
20. Where does our trash go?
In 2007 almost 65% of the
solid wastes produced in
U.S. went to 2,500 sanitary
landfills.
21. Landfilling
Landfilling is the term used
to describe the process by
which solid waste and solid
waste residuals are placed in
a landfill
Waste dumps or
uncontrolled land disposal
sites
Secure landfills for
Hazardous Waste
a) After geo-
membrane liner
has been
installed
b) After two lifts of
solid waste
c) Landfill with final
cover
22. Incinerators – burn trash
17% of trash is burned in
U.S.
Japan and Switzerland
burn more than 50% of their
trash.
23. Storage tanks are used to store petroleum or certain
other hazardous liquids. Leaking USTs can pose a serious
environmental threat if the stored petroleum or other
hazardous substance seeps into the soil and
contaminates ground water, which is the source of most
drinking water.
Storage Tanks
25. Recycling is the process of transforming waste materials
into usable resources. It is preferable to treatment and
disposal because it helps conserve energy and reduce
waste. Recycling, like garbage collection, is an optional
service provided at the discretion of local governments or
by private recycling companies.
