Abstract

Teak plantations generate each year large quantities of residues, including the first thinning wood and foliage. These by-products can be valorized as fuel to create added plantations and serve as adiversified cooking energy source. This study contributes to the diversification of green energy sources. The objective was to analyze and compare the energy characteristics of briquettes produced from different combinations of teak foliage and first-thinning wood with those of charcoal. Five briquette formulations were prepared with varying wood-to-foliage ratios (100:0, 75:25, 50:50, 25:75, and 0:100), alongside charcoal as a control. The net calorific value, ash content, and chemical element concentrations of the briquettes were determined. The results showed that only the briquettes with a 100:0 ratio exhibited energy characteristics comparable to charcoal. The calorific values and ash contents of the briquettes ranged from 17.18 to 29.28 MJ/kg and 7.73 to 38.59%, respectively, compared to 30.92 MJ/kg and 4.21% for charcoal.

Key words: Bioenergy, teak, briquettes, charcoal, comparison.
