5.1.1 MUNICIPAL SOLID WASTE

More commonly known as trash or
garbage—consists of everyday items we
use and then throw away, such as

product packaging, grass clippings,

furniture, clothing, bottles, food scraps,

newspapers, appliances, paint, and

batteries. This comes from our homes,

schools, hospitals, and businesses. ER

5.1.3 MAIN ELEMENTS INVOLVED IN MUNICIPAL SOLID
WASTE MANAGEMENT

1) Solid Waste Generation
+ Related to the production

of waste material through
various activities such as:

+ Solid waste generation results from :

1) Natural activities
+ involves the decomposition of organic matter and the natural
erosion of rocks and soil. For example, fallen leaves, dead
plants, and animal remains contribute to organic waste, while
weathering processes generate inorganic waste like sediment
and soil particles.

1) Residential

2) Human activities
+ includes a wide range of materials such as paper, plastic, glass,
metal, and organic waste. This includes waste from households,
businesses, industries, construction and agriculture.

3) Animal activities
+ primarily through the deposition of organic waste such as
feces, carcasses, and discarded food remnants.

2) Waste handling
« Handling refers to the various tasks associated with the management of
solid wastes, starting from their initial handling until they are placed in
containers designated for storage before collection or transport to drop-
off and recycling centres.
+ This process includes tasks like waste segregation, waste minimization
efforts, and the use of suitable containers or bins.

3) Waste storage

+ The initial step in solid waste
management takes place at the
household level, where temporary
storage of refuse occurs on the
premises. It becomes the
responsibility of individual
households or businesses to
manage the on-site storage of solid
waste properly.

4) Collection

+ Various collection methods are
employed, including curbside
collection, door-to-door collection,
and community drop-off points.

5) Transfer and Transport

« Transfer and transport pertain to
the methods, facilities, and
equipment employed to facilitate
the movement of wastes from one
location to another, often to a more
distant site.

The transfer and transport activities
involve the movement of waste
from the initial collection points or
transfer stations to treatment or
disposal facilities.

6) Resource Recovery and
Processing
+ Resource recovery involves a partial
solid waste disposal and reclamation
process, aiming to achieve reductions|
in future landfill volume
requirements.
+ Specific examples of material and
resource recovery include:
) Recycle ii) Composting
ii) Energy recovery
(Materials Recovery Center

7) Disposal

« The decomposition of solid waste can be carried out either aerobically or
anaerobically. Disposal marks the final stage of solid waste
management, where waste that cannot be recovered or recycled is
handled safely and responsibly.

+ Common disposal methods include landfilling and incineration.

5.1.4 STRATEGIES FOR MANAGING ENVIRONMENTAL

FRIENDLY WASTE MANAGEMENT

1) Reduce
Encourage the minimization of waste generation
through practices such as reducing packaging,
promoting reusable products, and implementing
efficient manufacturing processes.

SAY NO TO PLASTIC BAGS

2) Reuse

Promote the reuse of items whenever
possible to extend their lifespan, such as
donating or selling used goods, using
refillable containers, and repairing items
instead of disposing of them.

3) Recycle

Implement comprehensive recycling programs to
recover valuable materials from waste streams,
including paper, plastics, glass, metals, and organic
materials. Educate the public about proper sorting
and disposal practices.

4) Compost

Encourage composting of organic waste materials
such as food scraps, yard trimmings, and agricultural
residues to produce nutrient-rich compost for soil
amendment, reducing the need for chemical
fertilizers.

5) Energy Recovery

Implement technologies such as waste-to-energy
plants to recover energy from non-recyclable waste
materials through processes like incineration or
anaerobic digestion, reducing reliance on fossil fuels.

6) Public Awareness and Education
Educate individuals and communities about the
importance of waste management, proper waste

different waste management methods to foster
responsible behavior.

| 5.1.5. PROPERTIES OF
MUNICIPAL SOLID
WASTE

Municipal solid waste made up of
different materials, each with its own
characteristics. Understanding these
traits helps manage waste properly. They
include things like how much space it
takes up, what it's made of, and whether
it's harmful to the environment. By
knowing these properties, cities can
handle waste better, like recycling more
and reducing pollution.

have lower densities, while
