Abstract
This study evaluates the circular bioeconomy potential of forest residue-derived biochar through integrated analysis of: (1) agronomic effects in corn silage production, and (2) consumer willingness-to-pay (WTP) for meat from biochar-fed livestock. Combining field trials with discrete choice experiments (n=1,006 consumers), consumer are WTP a 2% average price premium driven by factors such as awareness, education, income, marital status, residence location and purchasing habits. Notably, 92% of participants were initially unaware of biochar or its benefits, highlighting the critical role of sustainability certifications and awareness in driving consumer WTP. While biochar amendment increased yields by 14%, biochar achieves positive NPV (Net Present Value) when transportation cost removed or yield gains exceeding 14% over 4 years. Key adoption barriers include limited consumer awareness, high initial investment, and inconsistent yield outcomes—particularly for large-scale farms. However, small farms targeting niche markets may find biochar more economically viable. The study concludes that supportive policies, improved supply logistics, and certification programs could enhance adoption by aligning environmental benefits with economic incentives.
