Pine-to-Bioenergy: Potential of pine sap as adhesive and pine flower biomass waste in the production of biobriquettes
Abstrak
waste into biobriquettes by using pine resin adhesive. This study aims to identify the effect of pine resin adhesive
concentration and the effect of grain size on the quality of the resulting biobriquettes. The production of
biobriquettes begins by processing pine flower waste into biochar using the pyrolysis method at 400 ◦C. Biochar
from pinecones was ground and sieved into sizes (250, 500, and 750 μm). Then proximate analysis (moisture
content, ash content, volatile matter, fixed carbon), and heating value were performed. Making biobriquettes
using pine resin adhesive with different concentrations (5, 10, and 15%) of the total mixture According to the
results, the ideal grain size was 750 m, the adhesive concentration was 15%, and the moisture content, ash
content, volatile matter content, fixed carbon content, and heating value were all respectively 2.23%, 4.51%,
30.23%, 70.04%, and 23.34 MJ/kg, and the longest flame was also determined to be 0.0250 g/sec. All of them
comply with universally accepted biobriquette standards (Indonesian National Standard 01–6235–2000), Japanese,
English, and ISO 17225. Biobriquettes have potential applications in bioenergy products. Investigation of
the economic feasibility of biobriquette production seen from Profit on Sales is 26.43%, Rate on Investment is
34.00%, Pay Out Time is 2.47 years, and Break Event Point is 49.22%
