Advantages of Plastic Wastes

Overview

  • Plastics can be classified into two categories; these are thermosetting plastics and thermoplastics.

  • Thermosetting plastic cannot be remodeled once they shaped.

  • Thermoplastics can be remodeled by applying heat and pressure can change the desired shape with solidifying and cooling them.

  • Four types of thermoplastics can be used in the construction of roads they are High-Density Poly Ethylene, Low-Density Poly Ethylene, Polyethylene Terephthalate (PET) and Polyurethane.

  • Adding 6 - 8 % of plastic waste to the bitumen aggregate hot mix can improve stability, strength, increase the lifespan of roads and reduce maintenance costs.

  • Molten plastic is a good binder, Bitumen and plastic binding is stronger than others.

  • Hot aggregate, shredded plastic and hot Bitumen will mix at 140°C-175°C of temperature for the construction of roads.

  • Plastic and Bitumen have good diffusion characteristics, it allows them to mix well and stick to the surface of the stone aggregates.

  • Since 2015 there is a mandate to use Bitumen with plastic for the roads of 50 kilometers Periphery of urban areas with over 5 lakh people.

  • 10 kilometer pilot stretches in every state.

  • Nodal officers also deployed across the country

  • The Swachhta Hi Seva campaign has been launched with an action plan to tackle plastic waste.

Benefits

  • Two-lane Road uses two tonnes of plastic waste per kilometer.

  • Plastic roads are environmentally friendly; they help in reducing plastic waste.

  • Plastics are water resistance, so the roads which are made with Plastic are more resistant to water.

  • plastic roads have increased durability

  • They have improved fatigue life.
