Performance, Emission, and Optimization Analysis of a Diesel Engine Fueled With Waste‐Derived Tallow Biodiesel

Engineering Reports, Volume 8, Issue 7, July 2026.
The growing demand for sustainable, low‐emission fuels has increased interest in waste‐derived biodiesel for compression ignition engines. This study experimentally evaluates mutton tallow biodiesel blends and applies a multi‐response optimization approach using the Taguchi method integrated with Gray relational analysis.

Gross Calorific Value of Indian Coals and its Correlation with Ash Content

Power Research - A Journal of CPRI, 2023
The Indian coals are a sub-bituminous variety, high in ash content and low in calorific value. The high ash content in Indian coals makes Indian coals more heterogeneous. The moisture and the ash content have a direct impact on the calorific value of the coals.

Greenhouse Gas Reduction Potential Through Bioheat for Remote Communities in Northeastern Ontario

GCB Bioenergy, Volume 18, Issue 7, July 2026.
Heating infrastructure in remote areas has high potential for fuel switching, possibly leading to decreased greenhouse gas emissions. Using a simplified life cycle analysis approach, we show that woody residues from the forest industry have the potential to reduce greenhouse gas emissions compared to commonly used fossil fuels.

Natural production of the calorific value from poplar clones and socioeconomic aspects of its wider use in Slovakia

Scientific Annals of the Danube Delta Institute, 2018
The calorific value produced from the poplar clone stands’ above-ground biomass was derived from its volume production, and calculated by mathematical model growth tables of I214 and Robusta poplar clones’ biomass density and dry biomass calorific value.
