2023年1月1日 · Pyrolyzing sewage sludge to biochar improves the physicochemical properties of sewage sludge and broadens the range of applications. Compared to the challenges of traditional methods that need expensive catalysts or intensive energy, sewage sludge derived biochar is promising particularly from a long-term perspective, considering that the input ...

2021年3月1日 · Production of biochar from sewage sludge (SS) is consistent with the goal of sustainable resource recovery and promotes a wastewater-based circular economy. Thermochemical conversion of SS to biochar resolves two major issues simultaneously as it minimizes the cost of disposal and acts as a resource to eliminate the toxic contaminants from ...

2023年9月1日 · Biochar derived from sewage sludge is an effective method for controlling air pollution. Biochar’s high porosity and surface area make it an ideal adsorbent for capturing volatile organic compounds (VOCs) and other air pollutants.

2023年1月23日 · Converting sewage sludge to biochar to serve as soil amendment and nutrient supplement to cropland may be an environmental benign and value-added approach to recycle the waste. Potting experiments were conducted to examine the efficacy of sludge biochar amendments on enhancing soil health and crop productivity.

2022年4月28日 · The main purpose is to present sewage sludge biochar as a potential fertilizer by evidencing the positive and negative aspects of different applications and the transformation of sewage sludge into biochar.

2023年1月17日 · Several new strategies for overcoming sludge biochar application barriers to realize highly efficient environmental improvement were highlighted, including biochar modification, co-pyrolysis,...

2023年4月27日 · The reduction and safe disposal of sewage sludge remains an urgent problem worldwide. In this work, biochar prepared from co−pyrolysis of sewage sludge and cotton stalk at different mix ratios and different pyrolysis temperatures was prepared using a novel microwave-assisted auger reactor.

2024年3月12日 · The objective of this study was to compare the effect of urban biological sewage sludge (i.e. the waste of activated sludge process) and its derived biochar as the soil amendments on the...

2025年1月4日 · A recent life cycle assessment (LCA) published in Cleaner Environmental Systems compared pyrolysis and hydrothermal carbonization (HTC) for converting sewage sludge into biochar and hydrochar, focusing on environmental impacts. The study from Gievers, et al highlights key benefits and trade-offs of these technologies versus conventional sludge ...

2025年2月23日 · Jakubus et al. studied sewage sludge-derived compost (SSC) and biochar (SSB) as organic soil amendments to enhance soil health. Results indicated SSC improved total organic carbon, nitrogen, and sulfur levels more effectively than SSB, while SSB excelled in available sulfur content.
