“…Teak, renowned for its hardwood properties, generates substantial residues across various industries, which can be transformed into a source of clean and accessible energy, contributing to environmental sustainability and addressing energy access challenges (Munsin et al 2022). Using teak residues for energy generation is a practical strategy aligned with the Sustainable Development Goals (SDGs).…”

The appropriate use of forest biomass can support the transition to a society with clean and renewable energy. In this context, the research aimed to evaluate the waste biomass from Tectona grandis L.f. for energy purposes. Seven teak wood waste types were used, accessible from the harvesting stage to wood processing. Physical attributes (moisture and basic density) and proximate analysis (volatile materials, ashes, and fixed carbon content) were evaluated, which were used to estimate the energy attributes (higher, lower, and net heating value and energy density). It was found that most waste components had moisture content averages below 30% and did not differentiate statistically. For the basic density, values varied between 366 and 519 kg.m-3. Proximate analysis and energetic attributes of the teak wastes support its feasibility for bioenergy use, focused on trimmings and thin logs. It was concluded that teak waste has the potential for energy purposes if its specific characteristics are considered and appropriate ways of use and conversion are chosen.

“…[9] Instead of dumping in landfills and open burning, sawdust could be used as an excellent resource for producing value-added bio-products. [10][11][12] Until now, even though governments have launched extremely stringent environmental regulations, the use of fossil fuels including coal, oil, and natural gas still represent 26.8%, 30.9%, and 23.2% of the world energy supply, respectively. [13] Among them, the reliance on the coal-fired power plant has been continuously reduced, especially in developed countries like Canada; however, the use of coal for generating electricity still is the main manner in the developing countries; for instance, 94% of the electricity in South Africa is generated from coal-fired power plants.…”

Hydrothermal carbonization (HTC) of sawdust for producing hydrochar was optimized using response surface methodology (RSM). After optimization, the combustion behaviour and other relevant fuel properties of hydrochar that was obtained at the optimized conditions were studied. Additionally, the aqueous phase obtained at the optimized conditions was recycled as the reaction medium for producing hydrochar and the influence of the aqueous phase recycling on the hydrochar yield and properties was evaluated. The results indicated that the highest hydrochar yield of 84.23 wt.% under the predicted optimum conditions of temperature of 162.23°C, 2.51 h, feedstock loading of 10.71 wt.%, and catalyst loading of 7.99 wt.%. Furthermore, it was found that the use of recycled aqueous phase as the reaction medium led to an increase in the hydrochar yield, higher heating value (HHV), and energy yield, and difference in combustion behaviour was minor. Overall, this study filled the gap in HTC literature regarding the effect of catalyst on hydrochar production and provided a practical solution to treat the aqueous phase.
