useless and unwanted products in the solid state derived
from the activities of and discarded by society. It is produced
either by - product of production processes or arise from the
domestic or commercial sector when objects or materials
are discarded after use.
Solid waste is are further
Biodegradable are those that can be decayed by
bacteria and other organisms, while those that
cannot undergo bacterial decay are considered
can be decomposed by
microorganisms such as
bacteria, enzymes and
an object that cannot be
decomposed into organic
and environmentally safe
waste products. This is
unlike biodegradable objects
which can easily be
decomposed by soil bacteria
into organic and safe waste
Three types of Solid Waste
House hold waste or Municipal Solid Waste
Industrial waste or Hazardous waste
Hospital waste or Biomedical waste
House hold waste that is
normally termed as
Municipal Solid Waste.
-mostly consists of household
waste, sanitation waste,
waste from streets, demolition
debris that arises during the
construction and demolition
of buildings and other
Industrial waste which in majority of
cases is termed as a Hazardous
-is a waste that is quite dangerous as
they consist of toxic substances that
are of chemical nature. This type of
waste is highly dangerous to human,
plants, animals and the overall
environment. As improper disposal of
the industrial solid waste may lead to
death, disease and sometimes an
environmental damage that may
continue for generations.
Corrosive - capable of chemically wearing substances away (corroding) or destroying
them. For example, most acids are corrosive. They can eat through metal, burn human skin
on contact, and give off vapors that burn the eyes. Acids found in batteries are corrosive.
Toxic - poisonous to people and other organisms. Toxic substances can cause illnessranging from severe headaches to cancer-and even death if swallowed, and many also can
be absorbed through the skin. Pesticides, weed killers, and many household cleaners are
Ignitable - capable of bursting into flames. Ignitable substances pose a fire hazard and
irritate the skin, eyes, and lungs. They also may give off harmful vapors. Gasoline, paint, and
furniture polish are ignitable substances.
Reactive - capable of exploding or releasing poisonous gas when mixed with another
substance or chemical. For example, chlorine bleach and ammonia are reactive. When they
come into contact with each other they produce a poisonous gas.
Hospital waste or Biomedical waste that
-This type of solid waste is most infectious
and can spread diseases and other types
of viral and bacterial infections among
humans and animals if not managed
properly in a scientific way. The hospital
waste includes solid waste in the form of
disposable syringes, bandages, cotton
swabs, body fluids, human excreta,
anatomical waste, bandages, expired
medicines, and other types of chemical and
biological waste. Hospital waste is equally
hazardous and dangerous as in case of
industrial waste if not disposed off or
Open Dumps- are sites of garbage disposal, expose garbage
to flies, rats and other vermin that then become carries diseases.
Ocean Dumping- another wrong disposal has been done for
several decades in the bottomless.
Landfills- where the waste is compacted and covered with soil
before a new layer is dumped on.
Incineration- is an alternative method of waste disposal,
which reduce the volume of waste.
Recycling- could reduce considerably the amount of garbage
by reusing glass, plastics, aluminium, metals, scrap iron,
and other materials.
-this would reduce air, water and land pollution.
