Recycling disposable bamboo chopstick waste as a renewable energy resource: Case study in Khon Kaen University, Thailand

Abstract This study focused on elucidating disposable bamboo chopstick (DBC) waste generation rate and identifying the appropriate carbonization temperature for recycling DBC as a renewable energy resource. A survey was conducted within area of Khon Kaen University (KKU). Of student population approximately 40,000, questionnaire completed by 470 students. The revealed utilization equivalent to 0.46 pairs person − 1 d . process wit 1-h carried out at 650 900 °C compare quality charcoal recycled from (DBC charcoal). prepared higher use fuel compared charcoal; with 5.3 times BET surface (62 × 10 3 m 2 kg ), 5% thermal efficiency (31%), 15 hydrogen (H) content (1.9% total mass content), 1.0 MJ heating values bombs calorimeter (32.8 ). biomass in gasification electricity could produce 0.0395% KKU consumption which estimated reduce CO emission 12.9 t yr well 43.7 or 0.399% around area.
