本研究は、タール褐炭とサトウキビバガスのブレンドを実験的に評価し、混焼による温室効果ガス（GHG）削減の可能性を示した。熱量分析や放射能測定の結果、50%混合で硫黄・灰分が低減する一方、発熱量は約8%低下した。結果は、バイオマス・石炭混焼がクリーンエネルギー生産に有効であることを示唆する。
English
This study experimentally evaluates blends of Thar lignite coal and sugarcane bagasse for co-combustion to reduce GHG emissions. Thermogravimetric analysis, calorific value, and radiometric measurements show that a 50% blend reduces sulfur and ash with a slight heating value loss. The findings support biomass-coal co-firing as a cleaner energy option.

日本のGX文脈において
日本では石炭火力のフェードアウトが進む中、バイオマス混焼は既存設備の活用策として検討されてきた。本論文はパキスタンの褐炭を対象とするが、混焼パラメータの基礎データは日本の石炭・バイオマス混焼の最適化にも応用可能であり、特にアジア地域の移行技術として参考になる。
In the global GX context
As global coal phase-down accelerates, biomass co-firing emerges as a transition option for coal-dependent economies. This paper provides experimental data on blend ratios, calorific values, and emission reductions, offering practical insights for policymakers and industry in developing countries seeking to decarbonize existing coal infrastructure.

📄 Abstract（原文）
Blends of coal with potential fuels, such as bagasse, may help reduce greenhouse gas (GHG) emissions. This study investigates the combined effect of Thar lignite coal and sugarcane bagasse on their suitability for gasification or combustion. Extensive experimental investigations were conducted to assess the suitability of these blends as potential fuels. The Gross Calorific Value of Thar coal blended with sugarcane bagasse was found to be ∼8,610 Btu/lb, 8,387 Btu/lb, 7,968 Btu/lb, and 7,448 Btu/lb after being mixed in ratios of 100%, 75%, 50%, and 25% with coal, respectively. Thermogravimetric analysis revealed weight loss with increasing temperature in Thar coal; the data obtained will help in setting parameters for fluidized bed conditions. The activation energy and frequency factor were determined to be 68.11 kJ/mol and 636.60 min −1 , respectively. Gamma spectrometry was also performed on these samples, revealing the presence of four main natural radioactive elements: 127.4 ± 45.2 Bq/kg for 40 K, 2.1 ± 0.3 Bq/kg for 235 U, 71.2 ± 12.1 Bq/kg for 238 U, and 20.7 ± 3.1 Bq/kg for 40 K, 235 U, 238 U, and 232 Th. The radiometric measurements of Thar coal show lower emissions compared with the global average values of activity concentration in coal samples. The composition of a 50% bagasse and Thar coal blend results in a notable reduction in sulfur and ash content; however, there is some compromise in the heating value (from 8,610 to 7,969 Btu/lb). The findings of the present study will significantly impact sustainable energy and environmental protection by demonstrating that blending sugarcane bagasse with Thar lignite coal can effectively reduce GHG emissions, thereby contributing to cleaner energy production. These results encourage policymakers and industry stakeholders to adopt biomass-coal blending for sustainable development and environmental benefits. Future research should focus on developing advanced gasification and combustion technologies, along with comprehensive emission control measures, to further reduce GHGs and enhance energy efficiency.
