DEFINE THE
PROBLEM
The chemicals used in the production
processes of textile fibers, water
consumption and greenhouse gas emissions
cause serious damage to nature.Every year,
over 100 million tons of fibers are produced
to be used in textile production in the
world. In this process, 1 million tons of
paint, 42 million tons of chemicals, 93
billion m3 of water are consumed and 1.2
billion tons of greenhouse gas emissions are
released. While 48 million tons of the
clothes produced after all these processes
are thrown away, 75% of these products,
which are thought to have expired, are
either incinerated or disposed of by burying
them in the ground.

DEFINE THE PROBLEM
Regular collection of textile waste with collection trucks
is another important step to raise awareness. In this
way, more and more attention is drawn to the
interaction of sustainability and fashion, and the trend
from fast fashion to slow fashion is increasing.
Consumers can contribute to reducing the effects of
environmental pollution and climate change caused by
the increasing solid waste landfills resulting from the
fast-wearing industry, by purchasing the products of
brands that are produced from longer-lasting fibers
such as Acrycycle and that promise to reduce their
negative effects on climate change.
In our project ; With Acrycycle, it is aimed to reduce the
need for new products and to minimize the
consumption of natural resources required for
production. The next goal of Acrycycle, which does not
use any harmful chemicals in the recycling process, is to
include textile products that have completed their
useful life in the production process without losing their
value. In this way, it is aimed to increase the
contribution to nature by recycling more waste.

INFORMATION
PAN is not a thermoplastic polymer like PE,
PP, polyester or polyamide that melt when
heated. With the PAN heated at a temperature
above 180ºC, the polymerization of the polymer
chain begins, making it rigid and dark. This
property makes PAN fiber the best-known
carbon fiber precursor.
Virtually everything that exists in the market
today containing PAN, are acrylic fibers and ABS
plastic, which, being considered a
thermoplastic, can be recycled in the same way
as conventional plastics.

GATHER THE
INFORMATION
Fabrics containing PAN fibers (acrylic fibers), in
most cases, do not use pure acrylic fiber, but a
mixture of other types of fibers such as cotton,
wool, polyester or polyamide with acrylic.
Mechanical recycling to separate the various
fibers of a fabric is very difficult and expensive,
due to the small diameter of the filaments (in
the order of a few microns), small difference in
density and the interweaving between them.
Acrylic fibers in fabrics are almost always dyed
or pigmented and that is why PAN, if recovered
from such fibers by chemical method, will
always have coloring or opacity, which makes
this PAN unfeasible for reuse in wet and dry
spinning processes, that mostly produce white
fibers.

GATHER THE
INFORMATION
As it is a very resistant and insoluble polymer,
there are few solvents that can be used
industrially in the chemical recycling of PAN by
dissolution, followed by its precipitation by
addition in water. PAN's main solvents are: DMF,
DMAc, nitric acid, sodium thiocyanate, zinc
chloride and ethylene carbonate. The use of
solvents in PAN's chemical recycling makes the
process expensive, mainly due to the need for
recycling for reuse and treatment of effluents
since they are toxic.
Fabrics containing acrylic fibers cannot be
depolymerized or cracked by thermal
processes, due to the cyclization of the chain
with the formation of solid waste of high
carbon content in the reactor.

ALPINE SKI HOUSE
GATHER THE
INFORMATION
Acrylic fiber and its fabrics cannot be used as
fuel in ovens and should only be incinerated in
special equipment, since they produce
hydrocyanic acid (HCN) and ammonia (NH3),
which are highly toxic gases.
Not even in the companies that produce
acrylic fibers, their residues and production
losses are recycled - despite being made up
only of polyacrylonitrile -, since some
characteristics of the threads such as thickness,
presence of solvent, yellowing or coloring make
commercialization unfeasible.

A PAN recycling method must be robust enough to use all
types of acrylic waste generated by the production chain,
which are:
Polymerization process, which during launch produces
polymer out of specification.
Start spinning, which produces fibers with solvents and
thicker filaments.
Loss of spinning during yarn production and dyeing.
Losses in the fabric cutting process for clothing
manufacturing.

ANALYZE AND SELECT
A SOLUTİON
Analyze the solution: First solution In recent years, many initiatives
have been initiated by non-governmental organizations, government
organizations and brands in order to ensure that the efforts to include
consumers in recycling are successful. As an example of these
initiatives; It can be mentioned about the responsibility of collecting
clothes that H&M and I:CO carry out together. In the process carried
out by the two institutions, consumers earn discount coupons that they
can use in their next shopping after delivering their old clothes to any
H&M store. As in this study, which can be given as an effective example
of increasing recycling in textiles, the aim is to increase social
awareness by explaining the importance and benefits of recycling.
Apart from the projects carried out by brands such as H&M, many
companies' websites have educational content on the subject. In
addition to these, the collection of textile wastes with collection trucks
at regular intervals is another important step taken to raise awareness.
In this way, more and more attention is drawn to the interaction of
sustainability and fashion, and the trend from fast fashion to slow
fashion is increasing. Consumers can contribute to reducing the effects
of environmental pollution and climate change caused by the
increasing solid waste landfills resulting from the fast-wearing industry,

Decomposition:The collected textiles are divided into
three categories by the people working in the sorting plants.
The sorting process, which is called second-hand use, use as a
cleaning cloth, and the part to be converted into raw materials,
and carried out in three categories, is generally done manually.
However, auxiliary systems such as belt conveyors and
collection boxes are also included in this process. Recently,
projects developed on automatic separation systems provide a
more sensitive separation process, allowing for higher quality
recycled materials to be obtained. That's why automatic sorting
machines play an important role in the recycling process. On
the other hand, textiles that cannot be separated sufficiently
due to technological deficiencies can generally be evaluated in
more value-added applications; It is used in less valuable
applications such as filling material, cleaning cloth production.
Automatic sorting technology was developed by the European
Commission's economic innovation initiative Textiles for
Textiles (T4T) project group to address the problem of using
textiles that cannot be separated sufficiently in applications
with relatively little added value.

With this developed technology, textile raw
materials are separated according to their
composition and color with the NIR (Near
Infrared) spectroscopy device, which is also
frequently used in pet bottle recycling. This
project has an investment cost of 1.3 million
euros. After the textiles are roughly sorted to go
to the second-hand clothing industry and be
included in the recycling chain, they are taken
to the automatic sorting machine and cut. The
development process of this project continues
with the contributions of seven different
companies from the sector as the FIBERSORT
project. The success criterion of the project is

Processing: After the textiles are sorted
according to their composition and color, they
are cut. Separating the aforementioned
products according to their colors eliminates
the need for repainting, thus saving energy and
labor, as well as reducing pollutants originating
from paint. Then, the cut clothes are mixed
with the appropriate material according to
their usage areas. In this process, long fibers
are used in clothing and home textile
applications, while short fibers are used in
nonwoven applications such as personal care,
automotive and insulation.
