The increasing global population and urbanization have led to significant challenges in waste management, particularly concerning vacuum blackwater (VBW), which is the wastewater generated from toilets. Traditional treatment methods, such as landfilling composting, often fall short terms of efficiency sustainability. Anaerobic digestion (AD) has emerged a promising alternative, offering benefits biogas production digestate generation. However, performance AD can be influenced by various factors, including composition feedstock, pH levels, presence inhibitors. This review investigates effects calcium oxide (CaO)-modified biochar (BC) an additive VBW. Modifying BC with CaO enhances its alkalinity, nutrient retention, adsorption capacity, creating more favorable environment for microorganisms promoting production, serves valuable source heat, fuel electricity. Additionally, processed through plasma pyrolysis ensure complete destruction pathogens while resource utilization. Plasma operates at extremely high temperatures, effectively sterilizing eliminating both harmful contaminants. process not only guarantees safety end products, but also transforms organic materials into outputs syngas slag. produced versatile energy carrier that utilized hydrogen, electricity, making it applications, cells power Furthermore, slag potential reuse or biofertilizer enhance soil properties. study aims provide insights using modified co-substrate systems. findings will contribute development sustainable efficient management strategies, addressing associated VBW renewable production.
