Correct option is C
The correct answer is (c) Plastic waste.
Explanation:
In June 2016, the Maharashtra government issued a notification through its Public Works Department (PWD) making it mandatory to use plastic waste in the construction of asphalt (bituminous) roads.
Information Booster:
· The Mix: The government decided to mix approximately 3% to 6% of plastic waste with every 100 kg of bitumen (tar).
· Purpose: The primary goal was to increase the durability and longevity of the roads. Studies indicated that plastic-coated aggregates are more water-resistant, which helps prevent the formation of potholes during heavy monsoons.
· Environmental Impact: This move was also aimed at reducing soil and water pollution by providing a large-scale method for disposing of non-biodegradable plastic waste like carry bags, milk pouches, and detergent bottles.
· Initial Implementation: The policy initially focused on roads within a 50 km radius of municipal corporations with populations over 5 lakh and municipal councils with populations over 2 lakh.
Benefits of Plastic-Bitumen Roads:
1. Higher Resistance: These roads show better resistance to deformation and water-induced damage.
2. Cost-Effective: It reduces the amount of expensive bitumen required, lowering the overall construction cost.
3. Eco-Friendly: It provides a productive use for "unrecyclable" plastic waste that would otherwise end up in landfills.
