Concept
Polymer Reprocessing
Polymer reprocessing
involves the
recovery and reuse of plastic materials
through mechanical, chemical, or
thermal methods
, helping to reduce
environmental impact
and
conserve resources
. It is a critical component of the
circular economy
, aiming to extend the
lifecycle of polymers
and
minimize waste
.

Concept
Circular Economy
A
circular economy
is an
economic system
aimed at
eliminating waste
and the
continual use of resources
through principles like reuse, repair, refurbishment, and recycling. It contrasts with a
traditional linear economy
, which follows a 'take, make, dispose' model, by
promoting sustainable practices
that extend the
lifecycle of products
and materials.
Concept
Mechanical Recycling
Mechanical recycling
is a process that involves the physical reprocessing of
plastic waste
into
new products
without altering the
polymer's chemical structure
. It is a crucial component in reducing
plastic pollution
and
conserving resources
, though it faces challenges with
material contamination
and
degradation in quality
.
Concept
Chemical Recycling
Chemical recycling
is a process that breaks down
plastic waste
into its
original monomers
or other
useful chemicals
, allowing for the creation of
new plastics
or other products without degrading
material quality
. It offers a potential solution to the limitations of
mechanical recycling
by handling mixed or
contaminated plastics
that are otherwise difficult to recycle.
Concept
Thermal Recycling
Thermal recycling
is a
waste management process
that converts
waste materials
into
usable heat
, electricity, or fuel through combustion or other
thermal processes
. This method not only reduces the
volume of waste
sent to landfills but also recovers energy that can be utilized in various applications, thereby contributing to
resource conservation
and
energy efficiency
.
Concept
Sustainability
2
Sustainability is the practice of meeting
current needs
without compromising the ability of
future generations
to meet theirs, emphasizing a balance between
economic growth
, environmental health, and
social well-being
. It involves adopting strategies and practices that promote
resource efficiency
,
reduce waste
, and support
long-term ecological balance
.
Concept
Life Cycle Assessment
Life cycle assessment
(LCA) is a
systematic method
for evaluating the
environmental impacts
associated with all
stages of a product's life
, from
raw material extraction
through to disposal. It provides a
comprehensive framework
to identify opportunities for
environmental improvement
and supports decision-making for
sustainable development
.
Concept
Material Recovery
Material recovery
is the process of extracting
valuable materials
from
waste streams
, aiming to minimize
environmental impact
and promote
resource efficiency
. It plays a crucial role in the
circular economy
by reducing the need for
virgin materials
and decreasing
landfill usage
.
Concept
Waste Management
Waste management
involves the collection, transportation, processing, recycling, and
disposal of waste
materials to minimize their
impact on the environment
and human health. Effective
Waste management
strategies are crucial for
sustainable development
and require the
integration of technology
, policy, and
community engagement
.
Concept
Environmental Impact
1
Environmental impact
refers to the effect that
human activities
and
natural events
have on
the environment
, encompassing
changes to ecosystems
, biodiversity, and
natural resources
. Understanding and mitigating these impacts is crucial for
sustainable development
and the
preservation of ecological balance
.
Concept
Resource Conservation
Resource conservation
is the practice of managing and
using resources
in a
sustainable way
to ensure their availability for
future generations
. It involves
strategies to reduce consumption
, waste, and
environmental impact
while
promoting efficiency
and
renewable alternatives
.
