Willingness to Use and Pay for Biobased Construction Materials: Citizen-Survey Results from Nine European Countries

This study examines European citizens’ attitudes and willingness to pay for biobased materials in construction and renovation. A survey conducted across nine countries with over 4500 participants revealed a generally positive attitude toward using recycled materials, such as glass and wood, while skepticism persisted toward biobased options. Many respondents expressed willingness to pay more for biobased and innovative materials, though a notable proportion would pay less for recycled and reused components. The findings highlighted significant national differences in attitudes and preferences, underscoring the influence of socioeconomic and cultural factors on the adoption of circular economy practices in the construction sector.
