PLASTIC SCENARIO

Road side Plastics Waste

Low density polyethylene(LDPE): bags, sacks, bin lining, andsqueezable detergent bottles etc

High density polyethylene(HDPE): bottles of pharmaceuticals, disinfectants,milk, fruit juices, bottle caps etc

Polypropylene (PP): bottle cap and closures, film wrapping forbiscuits, microwave trays for ready-mademeals etc.

Polystyrene(PS): yoghurt pots, clear egg packs, bottle caps, lids

Foamed Polystyrene: food trays, egg boxes, disposable cups,protective packaging etc

Polyvinyl Chloride(PVC): mineral water bottles, credit cards, toys, pipesand gutters; electrical fittings, furniture, binders,folders and pens; medical disposables; etc

CENTRAL MIXINGPLANT

PLASTICS – TAR ROAD

1. Better binding property2. Higher Softening point; withstands high temp.3. Lower penetration value; withstands higher load4. No stripping – Resists the permeation of water5. Higher Marshal Stability–increased strength of road6. Operation temperature range: 160-170 deg.C7. Cost less compared to CRMB.

Waste Plastics ( MSW, road side etc.)8. Better disposal of waste plastics9. No toxic gas evaluation - No to Dioxin10. Waste plastics Disposal - No longer a problem

Of Solution

• Water flow seepage affected• Land soil gets polluted• Solid waste --- Not disposed properly.• Non-availability of natural manure• Space not available

•Soil microbe activity reduced

• Water line clogging – CH4 evolution green house effect
