Abstract:As biochar carbon removal market is gaining significance as substantial contributor to mitigating climate change it becomes increasingly important to select a technology configuration for biochar production. By taking a platform-based design approach for non-assembled products, this study aims to identify the most profitable and capable integrated manufacturing system for biochar production, green energy conversion, and CO2 sequestration certificates. First, production platforms for biochar for soil amendment and green energy are established. Subsequently the respective product-, process- and raw-material platforms are developed. The report follows by establishing a comprehensive set of 26 criteria for evaluation of technology alternatives extracted from literature. An Analytic Hierarchy Process (AHP) analysis was performed, including extracting preferences from seven company stakeholders of a German biochar manufacturing company to determine criteria weights. Further, four technology alternatives available on the market were evaluated through the AHP model. The robustness of the model was then tested by performing a sensitivity analysis including potential scenarios for financial moderator variables. Results of the study show that stakeholders assign highest weight to the production platform for biochar for soil amendment. Results further indicate that despite having the highest initial investment, a two-step pyrolysis gasification system provides superior biochar cost, heat and electricity output, and carbon sequestration performance. The study's theoretical contribution is threefold: (1) It applies platform-based design theory for non-assembled products to biochar systems, (2) develops a production platform for biochar and (3) establishes a set of evaluating criteria for integrated pyrolysis manufacturing systems. The platform-based design perspective has valuable implications for managerial understanding of manufacturing capabilities, strategic planning, and further product and process development in biochar systems.
