• Biochar from olive pits and pine replaces limestone filler in asphalt.
• 75% reduction in CO2 emissions from asphalt production.
• Barcelona pilot: €90,000 funding, first streets in 2027.

"Barcelona plans to replace traditional asphalt with biochar made from olive pits and pine residues, a byproduct of Spain's olive oil industry. The process cuts CO2 emissions by 75% in asphalt production. Pilot tests begin in 2026, with first streets planned for 2027. The project is funded with €90,000 and aligns with EU construction product regulations favoring low-carbon materials."
