1.6 SCOPE AND LIMITATION OF THE STUDY
The
scope of the study covers the impact of recycling in preserving the
environment. However in the course of the study, the researcher
encounters some constrain which limited the scope of the study. Some of
these constrain are:
(a) Availability of research material: The
research material available to the researcher is insufficient, thereby
limiting the study.
(b) Time: The time frame allocated to the
study does not enhance wider coverage as the researcher has to combine
other academic activities and examinations with the study.
(c)
Finance: The finance available for the research work does not allow for
wider coverage as resources are very limited as the researcher has other
academic bills to cover.
1.7 DEFINITION OF TERMS
Recycling
Recycling
is the process of converting waste materials into new materials and
objects. It is an alternative to "conventional" waste disposal that can
save material and help lower greenhouse gas emissions (compared to
plastic production, for example). Recycling can prevent the waste of
potentially useful materials and reduce the consumption of fresh raw
materials, thereby reducing: energy usage, air pollution (from
incineration), and water pollution (from land filling). Recycling is a
key component of modern waste reduction and is the third component of
the "Reduce, Reuse, and Recycle" waste hierarchy.
Waste
Waste and
wastes are unwanted or unusable materials. Waste is any substance which
is discarded after primary use, or it is worthless, defective and of no
use.
Examples include municipal solid waste (household
trash/refuse), hazardous waste, wastewater (such as sewage, which
contains bodily wastes (feces and urine) and surface runoff),
radioactive waste, and others.
Solid waste
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,
Pollution
Pollution is the introduction of
contaminants into the natural environment that cause adverse change.
Pollution can take the form of chemical substances or energy, such as
noise, heat or light. Pollutants, the components of pollution, can be
either foreign substances/energies or naturally occurring contaminants.
Pollution is often classed as point source or nonpoint source pollution.
