What is the main objective of Covestro's EU-funded project on bio-based aniline?

The main objective is to build a semi-industrial continuous production line for bio-based aniline that can directly replace conventional fossil-based aniline in polyurethane manufacturing, using renewable plant sugars from broadleaf forest biomass via continuous fermentation technology.

Why is bio-based aniline significant for reducing carbon emissions in the polyurethane value chain?

Conventional fossil-based aniline production for MDI—a key polyurethane intermediate—emits approximately 20 million tons of CO₂ annually worldwide; the project aims to drastically cut this carbon footprint by replacing petroleum-derived feedstocks with renewable biomass, while ensuring full compatibility with existing MDI production standards and infrastructure without requiring downstream modifications.

Covestro Leads EU Bio-Based Aniline Project

Jun 23, 2026

Covestro launched an EU-funded project to mass-produce bio-based aniline via continuous fermentation for the polyurethane industry. This initiative aims to replace fossil-based feedstocks, potentially cutting annual carbon emissions by 20 million tons.
