Production of liquid smoke using auto thermal slow pyrolysis method and its application for plant pesticide

Abstract This study investigates the production of liquid smoke using autothermal slow pyrolysis, utilizing organic waste materials such as leaves, wood, and coconut shells as feedstock. Autothermal slow pyrolysis offers a sustainable method to convert biomass into liquid smoke, utilizing heat generated within the pyrolysis process. The produced liquid smoke was rigorously tested in laboratory settings to assess its chemical composition and conformity with SNI 8985:2021 standards. Results indicate that the liquid smoke meets the specifications outlined in the standard, confirming its quality and safety for application as a plant pesticide. Furthermore, efficacy tests demonstrated significant insecticidal, positioning the liquid smoke as a viable biopesticide alternative. The environmental impact of this innovation program includes a reduction of non-hazardous waste, specifically organic waste, by 0,531 tons per year. Additionally, the program provides cost savings within the company by reducing waste disposal expenses and by replacing chemical liquid smoke with the organic waste-derived liquid smoke, resulting in savings of Rp 9,108,000 in 2024. This research underscores the dual benefits of environmental sustainability and economic efficiency through the utilization of liquid smoke derived from organic waste via autothermal slow pyrolysis, promoting eco-friendly pest management solutions while reducing reliance on synthetic pesticides.
