Recycling of PET waste bottle to textile valuable product.


Published on

As PET bottle is non biodegradable and cause many several major problem to nature to overcome of it such project are every useful.

Recycling of PET waste bottle to textile valuable product.

  2. 2. INTRODUCTION :-  Polyethylene terephthalate, commonly known as “PET” in packing industry and polyester in textile industry.  Polyester is made from petroleum, that creates damaging environmental impacts during extraction process.  Recycling is most viable approach to reduce solid waste.  Therefore, The world’s most recyclable polymer is “POLYESTER” .
  3. 3. CONSUMPTION OF PET 91% 8% 1% World wide consumption. Plasatic other than PET Pet Consumption PET which is getting recycled
  4. 4. CONSUMPTION OF PET The worldwide consumption of the bottle grade PET was 18 million metric tonnes. It represents almost 8% of total demand of standard plastic in 2015. Out of these, only 9% of PET is getting recycled.
  5. 5. What is “PET”?  PET known by the trade names Mylar, Dacron and terylene.  Have high crystalline melting temperature at 260°C.  It has outstanding crease resistance, good abrasion resistance.  It can be blended with cotton and other cellulosic fibers to give better feel. Application:- Apparel purpose In industries Manufacturing of container Production of disposal. Structure of PET
  6. 6. PET FEATURES High Tensile strength Good Abrasion resistance High crystallinity Cheaply available  Easily recyclable Tearing strength Less shrinkage
  7. 7. AIM :- To understand the properties of the recycle polyester fibre in the form of fabric as well as yarn against the virgin polyester yarn. To reduce PET waste disposal which has created serious environmental and economic concern.
  8. 8. Collection Separation & Drying Separation of impurities Melt Spinning Extrusion Winding Preparation Of PET
  9. 9. Pet flakes 1.05 kg Depolymeri- zation glycolysis Fine filtration Repolymerisatio n Finishing Recycled PET pellets 1.03 kg (Solid waste 0.02 kg) Spinning Recycled PET filament fibre 1 kg. (Solid waste 0.03 kg) C h e m i c a l r e c y c l i n g b y g l y c o l y s i s m e t h o d . Ethylene Glycol
  10. 10. Problem regarding PET waste. PET waste disposal has created serious environmental concerns. As PET waste is solid waste, so it takes more space. It is non-biodegradable, in nature. It causes serious land filled problems.
  11. 11. Landfill issue :- Plastic is non biodegradable waste, they are accurate over time in land filled. 1 billion plastic are trash for one year. Only 1% plastic are recycled remaining are land filled. About 92% are overall plastic in land filled.
  12. 12. Solution to all stated problems  Plastics are a versatile recyclable material.  Recycling is most viable approach to reduce solid waste.  It can be valuable asset to your corporate Green recycling program.  Creating new materials from existing materials uses significantly less energy than using raw materials.  So it is necessary to recycle PET wastages.
  13. 13. Polyester { Physical Properties } Virgin Polyester  Moisture regain values of virgin polyester of 150 denier is 0.040%.  Bending length results of virgin polyester fabric of 150 denier is 2.75  Abrasion resistance: 1- 7.83 %  Tenacity:23.55  Tearing strength 150 denier:- Wrap:-2986.6 Weft :-3408.6 Recycled Polyester  Moisture regain values of recycled polyester of 150 denier is 0.045%  Bending length results of recycled polyester fabric of 150 denier is 2.1  Abrasion resistance: 1- 1.16%  Tenacity:20.24  Tearing strength 150 denier:- Wrap:-2858.6 Weft :-2986.6
  14. 14. Comparison Of Chemical Properties. Virgin Polyester Dye ability (corallene yellow):- 46.26 Crystalline region:- 88% Amorphose region:- 12% Recycle Polyester Dye ability (corallene yellow):- 32.54 Crystalline region:- 82% Amorphose region:- 18%
  15. 15. Company making use of recycled PET bottles to polyester fibre.  Polygenta ltd- Nasik  Reliance industry limited(RIL)- Naroda  Arora fibre- Dadra & Nagar Haveli  Panchal plastic- Malad West, Mumbai  Krishna Plastic- Baroda Many more industries are carry out this recycling process in many different ways and they are successful too.
  16. 16. Conclusion In recent our institute(DKTE) has carried out experimental work on the recycling of PET flask bottles. This are following results:-  The recycled polyester has increased amorphous region compared to the virgin polyester.  Improvement in dyeing and physical properties of fibre.  It will surely solve the problem regarding waste and garbage's of PET bottles.  It also solve land filled problem.
