Context
- The Central Road Research Institute (CRRI) focuses on research and development in road and runway infrastructure and promotes the use of bio-bitumen as a sustainable alternative to traditional bitumen.
- Bio-bitumen, derived from organic materials through pyrolysis, offers environmental, economic, and import-reduction benefits, addressing India's growing demand for bitumen in road construction.
Details
Key Points
- Bio-bitumen:
- Definition: A sustainable, petroleum-free alternative to traditional bitumen, also known as bio-asphalt.
- Sources: Manufactured from organic materials such as bio-char, bio-oil, and lignins derived from plant cell walls.
- Production Process: Produced through pyrolysis, which involves heating waste materials to around 500°C without oxygen.
- Benefits of Bio-bitumen:
- Reduced Imports: Decreases dependency on imported bitumen, leading to savings on foreign exchange.
- Environmental Impact: Utilizes organic waste materials, addressing issues like stubble burning and promoting sustainability.
- Economic Benefits: Substantial savings on foreign exchange and promotion of renewable resources.
- Promotion of Bio-economy: Encourages the use of sustainable resources in construction, boosting the bio-economy.
- Bitumen:
- Definition: A black substance derived primarily from crude oil, composed of complex hydrocarbons and elements like calcium, iron, sulphur, and oxygen.
- Properties: Renowned for waterproofing and adhesive properties, making it vital for construction.
- India’s Current Situation – Bitumen:
- Demand Growth: Increased road construction activities have significantly raised bitumen consumption.
- Import Dependency: India imports approximately half of its annual bitumen requirement.
- Statistics: In 2023-24, India imported 3.21 million tonnes and produced 5.24 million tonnes of bitumen locally.
