The Bangalore International Airport Limited (BIAL), on Thursday, began using plastic waste for road work. Plastic- coated bitumen will be used to build 50 km of roads within the airport campus. The BIAL had launched the #PlasticBeku campaign, to collect plastic required for construction. Plastic donation bins were placed at several locations on the airport campus. The BBMP is also providing BIAL with plastic waste for this project.
Sundar Chandramouli, vice-president, BIAL, said that about one tonne of plastic is required to lay a km of the road. Out of the required 50 tonnes, about 10 have been collected from various quarters. “It is environment-friendly as it uses waste plastic. Furthermore, the strength of the road is comparatively high,” he sad.
Kiran Kumar, Associate Professor, Civil Engineering, Sri Krishnarajendra Silver Jubilee Technological Institute, told mediapersons that about 6-8% bitumen of the asphalt will be replaced by shredded plastic of low densities that will act as a binder. “This process will result in no pothole formation, very little water seeping in and longevity of roads,” he said.
