Agricultural Residue Emission Factors and Biochar Energy Analysis for Korea

A 2026 study by Sunyong Park provides a comparative analysis of emission factors and energy metrics for open-field burning versus biochar production from agricultural residues in Korea. The dataset likely contains mass- and energy-normalized emission factors for CO, CH₄, CO₂, NOₓ, N₂O, and particulate matter, as well as energy input and return on investment calculations. It is stored in an XLS file of 9.5 KB.

Use Cases

• Comparing emission reductions based on quantified emission factors for different residue types
• Evaluating biochar energy viability based on energy return on investment (EROI) values
• Estimating greenhouse gas impact reductions using 100-year global warming potential metrics
• Analyzing net energy potentials for specific crops like apple pruning residues

Strengths

• Provides specific emission reduction percentages (e.g., CO, CH₄, CO₂ reduced by 40.6–46.5%)
• Includes concrete energy metrics, such as energy inputs of 2.65–3.50 MJ/kg and EROI values from 8.57 to 10.06
• Calculates a specific annual climate impact reduction of approximately 192,967 tCO₂eq/yr

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
