Low‐Carbon Recycling of Engineering Muck Through Phosphogypsum: Modeling, Optimization, and Durability Performance Investigation

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
With the rapid development of urban infrastructure in China, engineering muck has emerged as a potential urban risk. The improper disposal of engineering muck not only results in the inefficient occupation of land resources but also poses serious threats to ecological systems and geotechnical stability.

Phosphogypsum based gypsum binder

open access: yesBulletin of Prydniprovs’ka State Academy of Civil Engineering and Architecture, 2019
Problem statement. Phosphogypsum-based binding materials without pretreatment have poor physical and mechanical characteristics compared to binders made of natural raw materials. This is due to the high value of their specific surface area, which in turn leads to an increase in water demand.

Toward enhanced nutrient circularity: Lessons from a multidisciplinary conference

open access: yesNatural Sciences Education, Volume 54, Issue 2, December 2025.
Abstract The global agricultural sector faces the challenge of ensuring food security while minimizing the environmental impact of conventional practices. Waste‐derived fertilizers have gained attention for their potential to enhance nutrient circularity, yet regulatory, environmental, and agronomic barriers hinder widespread adoption. To address these

Exploring Sulfate as an Alternative Electron Acceptor: A Potential Strategy to Mitigate N2O Emissions in Upland Arable Soils

open access: yesGlobal Change Biology, Volume 31, Issue 8, August 2025.
This study explored the use of sulfate‐based soil amendments as a new method to mitigate N2O—a powerful greenhouse gas—from agricultural soils. Laboratory and field experiments showed sulfate treatments significantly lowered N2O emissions without negatively affecting crop yields, mainly by altering soil microbial processes.
