A Process of Producing Bio-Bitumen from Pyrolysis of Lignocellulosic Biomass

In 2023, the global demand for bitumen was approximately 120 million metric tons per year. If even 5-10% of this demand is replaced by biobinders in the next decade, the market for biobinders in road construction could reach 6-12 million metric tons annually.

The bio-bitumen produced from the pyrolysis of lignocellulosic biomass serves as a sustainable alternative to conventional petroleum-based bitumen for use in road construction and maintenance. Its application is particularly valuable in bituminous pavement layers such as binder and wearing courses, where it can partially conventionalbitumen. By utilizing agricultural and forestry residues, this bio-binder contributes to waste valorization, reduces carbon emissions, and supports environmentally friendly infrastructure development.

The production of bio-bitumen from lignocellulosic biomass offers several key advantages. It promotes sustainable waste management by utilizing agricultural and forestry residues that would otherwise go unused. The process reduces dependence on fossil fuels and contributes to lowering carbon emissions, supporting environmentally friendly construction practices. Additionally, the bio-bitumen exhibits performance characteristics similar to conventional bitumen.
