Plastics Waste Recycling for Sustainable Development

Plastics Waste Recycling for Sustainable Development:
Material Development attributed to “AGES”.
1. Development of innovative materials either
Plastics or Non-Plastics - Fundamental aspects of Modern civilization.
2. Played crucil rolle in social cultural and
technological growth of the mankind all over the world.
3. Historical periods of our society attributed to the dominance of the particular material in a
particular period, stone age, bronze age, iron age, steel age, silicon, silica age.
4. Today it would not be exaggerated if we ascribe that we live in a “Plastics age".

Plastics applications - Historical Background
1. Use of natural polymers in 35,000 BC.
2. Shellac in Indian turnery as hot wood, varnish or a binder.
3. Natural polymer - bitumen sealants for water proofing in the ancient cities.
4. In 1868 - first first commercial plastics plastics, Celluloid developed in USA.

Plastics Realities vis-à-vis environment
To adopt strategy of “5 R’s” -
Reduce for source reduction,.
Re-use for multiple use of products.(e.g. 5 
gallon polycarbonate mineral water bottle).
Recycle for value added products.
Recovery for feedstock and energy generation
Recovery for feedstock and energy generation has to be realised in practical sense to deal with the Plastics Waste Management/
environmental issues in the country.
Repair of plastics products for damage.

Why Plastics Waste Recycling ?
• Clean Environment
• Employment opportunities
• Economical Products
• Manufacturing of numerous recycled products which substitute conventional materials for cost effectiveness. viz. Synthetic wood, garden furniture, pallets, fencing post, etc.
• Business opportunities

Market demands sorting by Types of Plastics:
MECHANICAL RECYCLING OF PLASTICS: 
FEEDSTOCK RECYCLING OF PLASTC:
Value Addition/Conversion of Plastics waste into Wealth:

Indian Experience of Value Addition in Plastics Recycling:
Successful Innovation of an Indian Company in Commingled Plastics Waste Recycling:
1. Unique process devloped to produce environmentally Wood substitute(Chipboard) for numerous furniture applications, pallets, interior decoration, doors, signages, etc.

Composition of the product:
1. Proprietary process developed by Indian
company using multi-layered paper waste
polyethylene polyethylene and and aluminum aluminum foil to produce wood substitute “Eco” products.

Properties of “Eco” Chipboard:
1. 100% termite and borer - resistant, denser than wood, maintenance free.
2. Excellent insulation and sound proofing quality & can be recycled
3. It can be painted, laminated, Polished like other wooden material.
4. It can be sawn, moulded-cut, glued screwed, etc. like other Wood based board.(high compression strength)
5. Thermoformable, Formaldehyde-free
6. Resistance to acids alkalies solvents and other chemicals.
7. Cost effective.
Regranulation of Mixed Waste
Output Capacity of 2000kg per hour

Stage 1: Shredded waste plastics are separated from metal and mineral impurities by magnetic and screen separation technique.
Stage 2: The Shredded Waste plastics are separated from Organic and Inorganic impurities.
Stage 3: The Shredded waste plastics of less than 1g/cm3 (PVC, PS, PET…) are separated and dried.
Stage4: Granulationby extruder with twin force
feeder and degassing unit.

Innovative Centrifugal technology for Separation of Waste
• Excellent separation of Plastics of different
density.
• Fine separation independent of size or form of the flake
• High throughput due to quick separation (300 - 5000 kg per hour).
