PLASTIC & TEXTILE BAGS Plastics manufacturing consumes 400 kwh/mt while composite textile mills consume 1310 kwh/mt Textile contributes 30% SOx (second highest by any sector) and 23% NOx (highest by any sector) Source : Warmer Bulletin, July 01 This gives a comparative analysis of environmental burden generated by paper, jute & textile bags which are not visible to naked eyes though, in comparison to plastic bags!

Increase shelf-life of contents Essential for packaging / carrying of confectionery, bakery products Essential for packaging / carrying hygroscopic products like sugar / salt / jaggary Convenient for carrying fish / meat / poultry and other wet food products – no other appropriate alternatives Essential to carry commodities during rainy season Add convenience to day-to-day life PLASTICS BAGS / CARRY BAGS

PLASTIC & PAPER CARRY BAGS Plastics and Paper both can be recycled. However it takes 91% less energy to recycle a kg of plastic than a kg of paper. Source: ULS LCA Report, USA and other reports

Slide 20 -

150,000 plastic bags of 20 cm x 30 cm x 40 micron needs 1 small tempo for transportation Paper bags of same size & number need ~ 10 such tempos for transportation - due to higher weight and volume Consuming more fuel and causing more air pollution PLASTIC & PAPER CARRY BAGS

DESPITE ALL THESE POSITIVE ATTRIBUTES … PLASTIC BAGS ARE UNDER SCANNER

Slide 22 -

MAJOR ISSUES Health & safety Toxicity Biodegradability Disposal & waste management

Slide 23 -

HEALTH & SAFETY Polythene is approved safe material for Use … In contact with food, pharmaceuticals and drinking water As implants within human body In medical applications like IV bottle, Packaging of tablets For Packaging of Liquid Milk Plastic Carry Bags are generally made from Polyethylene

Slide 24 -

TOXICITY Issue: Plastics are termed as toxic and injurious to health Fact: Plastics are inert materials and do not pose any danger of toxicity Emissions during processing of plastics are well within regulatory norms (study by SIIR – Delhi) Additives used in plastics are approved as per BIS / FDA standards Emissions at fire situation have similar or lesser implications in comparison to situation involving natural organic materials like wood, paper & cotton Emissions during burning of paper and polyethylene are similar

Slide 25 -

BIODEGRADABILITY Issue: Non-biodegradability property of plastics carry bags is termed as the major reason of waste management problem Plastics are useful for its long life characteristics Nothing decomposes substantially in modern landfills. It requires additional mechanical action for composting degradable waste Indian Landfills does not practice Composting Activity

Slide 26 -

BIODEGRADABLE OR RECYCLABLE PLASTICS ? Compostable plastics will degrade/compost only in composting conditions The concept of Biodegradable Plastics will encourage littering Spurious products cannot be detected in market place causing flooding of fake bags A mixture of degradable and non-degradable plastics will disturb the plastics recycling activity During decomposition stage biodegradable plastics emit CO2 and CH4 – both green house gases

Slide 27 -

BIODEGRADATION OR RECYCLING ? Biodegradable Plastics have been developed However these are required in applications where recycling is not possible or difficult Developed countries – major manufacturers of BD Plastics – have not mandated use of Biodegradable Plastics Carry Bags in their countries Reuse and Recycling is preferred over degradation to encourage Resource Management

Slide 28 -

USE OF BIODEGRADABLE PLASTICS Recommended applications of BD plastics: Nursery Bags, Mulch/Agricultural film, One – time use Cutlery / Cups etc to be Carried in Ships / Remote areas Lamination on jute – paper for Relevant Packaging Applications etc

Slide 29 -

DISPOSAL Issue: Plastics are blamed as the major cause of MSW problem Facts: According to studies plastics form about 5% of total MSW in major Indian Metros A recent study at Deonar dumping area (Mumbai) reveals that ~ 90 % of plastics waste brought to the landfill are picked up by rag pickers and sold to waste trades for recycling

Slide 31 -

ISSUE – INDIAN CONTEXT WHILE ALL SOLID / THICK PLASTICS WASTE IS SYSTEMATICALLY PICKED UP BY THE WASTE COLLECTORS FOR RECYCLING, DISPOSAL OF THIN PLASTIC CARRY BAGS, SINGLE-USE PLASTIC WASTE AND MULTI-LAYER PACKETS, ABANDONED BY THE WASTE PICKERS, HAVE CREATED SOLID WASTE MANAGEMENT PROBLEM

Slide 32 -

PLASTIC CARRY BAGS : GLOBAL MATRIX No developed country in the world has any thickness restriction of Plastic Carry bags No country in the world has mandated use of Biodegradable Plastics for any mass commodity product like Carry Bags In California - USA, initial measures for banning of normal plastic bags in favour of biodegradable plastics / paper bags has been stricken down by the Superior Court asking for conducting LCA study on the products France dropped its earlier proposal for banning of normal plastic bags in favour of Biodegradable Plastic Bags on the direction from EU Parliament

Slide 33 -

PLASTIC CARRY BAGS : GLOBAL MATRIX Australia has plans to reduce the use of thin HDPE bags by 50% over a period of three years Some developed countries levy tax on all packaging materials including plastic carry bags – to meet the cost of managing the waste Many developing countries including China & India have thickness and size restrictions Only Bangladesh and some African nations have imposed ban on plastic carry bags

Slide 34 -

PLASTIC CARRY BAGS : INDIAN RULES IN THE STATES OF MAHARASHTRA, GOA, WEST BENGAL, MEGHALAYA, PUNJUB, HIMACHAL PRADESH, KERALA THE THICKNESS RULE VARIES FROM 30 TO 70 MICRONS IN DELHI , CHANDIGARH AND J & K, PLASTICS CARRY BAGS ARE BANNED ALL OTHER STATES FOLLOW MoEF RULE OF 20 MICRONS

Slide 35 -

SOLUTION TO DISPOSAL PROBLEM Segregation at source – awareness among citizens against littering Proper system for collection of segregated wastes for facilitating recycling Incentives / encouragement for recycling Upgradation of the existing mechanical recycling technology Encouragement for alternate methods of recycling / recovery of energy
