Bengaluru bio bitumen project aims to lower road construction emissions with plant based alternative
urbanacres.inA Bengaluru led initiative is pushing bio bitumen as a substitute for petroleum based road materials. The project uses lignin and other plant residues to create a binder that can replace conventional bitumen in road construction. Early trials suggest the material can cut lifecycle carbon emissions compared to standard asphalt while maintaining performance in Indian climate conditions. The effort targets the large carbon footprint of India's road building sector, which consumes millions of tonnes of bitumen each year. If scaled, bio bitumen could reduce dependence on fossil fuel derived inputs and create new revenue streams for agricultural waste processors. The next step involves longer road trials and cost benchmarking against traditional bitumen to assess commercial viability.
