The Potentials of Biochar Produced by Pyrolysis Using Biowastes

Abstract

The rising generation of biowaste from agricultural, municipal, and industrial activities poses significant environmental and waste management challenges. Pyrolysis presents a viable solution by converting biowaste into biochar, bio-oil, and syngas, offering both waste reduction and resource recovery opportunities. This study investigates the influence of key pyrolysis parameters—temperature, heating rate, and residence time—on biochar yield and quality. Findings reveal that slow pyrolysis (300–500°C) with extended residence time optimizes biochar production, while fast and flash pyrolysis (500–1000°C) prioritize bio-oil and syngas yields, respectively. Furthermore, the study highlights biochar’s potential for soil improvement, carbon sequestration, and pollution mitigation. However, challenges such as the absence of standardized guidelines, limited awareness, and inadequate government incentives hinder its large-scale adoption. To overcome these barriers, the study recommends optimizing process conditions, establishing regulatory frameworks, promoting renewable energy applications, and conducting further research on feedstock variability. Additionally, government incentives and public awareness initiatives are essential to enhance adoption. A thorough economic and environmental assessment of large-scale biochar production is necessary to ensure its long-term sustainability. With continued research, policy support, and technological advancements, pyrolysis can significantly contribute to sustainable waste management, renewable energy generation, and environmental conservation.
