Abstract

Young coconut peel waste (YCPW) is still an underutilised material because the waste is generally only transported, dumped, landfilled, or incinerated. The objective of this study was to determine the reliability of the pyrolysis process in converting coconut shell waste into charcoal and liquid smoke to reduce the amount of waste at the source. Pyrolysis of 1,000 g YCPW yielded 418.8 g charcoal, 271 g liquid smoke, and 82.2 g tar. The liquid YCPW smoke was tested as a preservative for coconut sap after redistillation. It was shown to have antimicrobial activity, with the following parameters for the sap: (i) prevention of pH drop and (ii) suppression of reducing sugar level. The resulting charcoal powder was mixed with 10% starch paste. The mixture was then hydraulically pressed and sun-dried to produce a compact and dry charcoal briquette. The briquettes were tested according to ASTM D5142-02, and the YCPW briquettes were found to have water content, volatile matter content, ash content, solid carbon content, density, strength, and heating value of 7.79, 26.74%, 2.76%, 68.66%, 0.62 g/cm3, 32.44 kg/cm2, and 6.21 cal/g, respectively. Thus, the YCPW charcoal briquettes met the quality standards for public fuel according to Indonesian and Japanese standards.
