Life cycle environmental and economic assessment of Phosphogypsum utilization in China
Phosphogypsum (PG), a byproduct of the phosphate fertilizer industry, poses significant environmental challenges due to its huge production and complex composition. Efficient and large-scale utilization of PG remains a global issue. China, as the world's largest producer and discharger of PG, faces a relatively low utilization rate and urgently needs effective management strategies. This study evaluates the environmental and economic performance of the main PG treatment pathways in China using life cycle assessment (LCA). The results reveal notable benefits for all three utilization technologies, with sulfuric acid co-production cement (PSC) offering the greatest environmental advantages and β-building gypsum (PBG) providing the highest economic benefits. Scenario analysis suggests PSC as the most effective strategy for achieving dual environmental and economic gains, making it a strong candidate for large-scale implementation. These findings provide critical insights for future PG management strategies in China.
期刊介绍:
The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns.
Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
