摘要

Purpose of Review

The land application of biosolids is a nature-based solution for sludge resource utilization. However, the potential pollution risks and climate change implications caused by the persistent emission of odor and greenhouse gas (GHGs) from biosolids should not be overlooked. It is crucial to update the understanding of biosolids gaseous pollution prevention in light of the emission characteristics and generation mechanisms.

Recent Findings

Biosolids can be significant sources of GHGs and odors. Microbial activity in biosolids serves as the key driving force behind the generation of malodorous substances and GHGs. Thus, the emission patterns vary substantially, depending on the combined influence of physico-chemical and microbial properties of biosolids under specific environmental conditions. Given this complexity, accurately assessing associated risks and effective pollution prevention remain challenging.

Summary

Focusing on gaseous pollution associated with biosolids land application, this review summarizes the emission characteristics of odor and GHG, explores the generation mechanisms and key affecting factors, and discusses strategies for pollutant mitigation, to facilitate the environmentally sustainable development of sludge resource utilization.
