The article takes a flue gas desulfurization project and a systematic project for comprehensive treatment of saline-alkali soil in Inner Mongolia, China as examples, discussing in detail the process flow, implementation plan, treatment effect, and risk assessment of the projects. It also quantitatively evaluates the benefits generated by the comprehensive projects. This project utilizes DS cycle economy technology to use solid waste steel slag as an absorbent for flue gas desulfurization, achieving a desulfurization rate of 99.6%. The by-product desulfurized steel slag generated is used to improve saline-alkali soil, significantly improving its physicochemical properties such as salt content, EC value, pH value, SAR, ESP, and compressive strength, as well as its strong alkalinity and high saltiness. At the same time, the content of heavy metal elements represented by Cr is lower than various soil quality standard values at home and abroad. The proportion of exchangeable F1-Cr is low and decreases with the increase of DS amount, posing a low risk of environmental pollution.

Preliminary estimates suggest that if steel slag is used as a 1:1 substitute for limestone as a desulfurizer, China's flue gas desulfurization treatment could consume approximately 150 million tons of steel slag annually. Utilizing the resulting desulfurization by-products to improve saline-alkali sand wastelands not only finds a new method for treating China's 1.5 billion acres of saline-alkali land but also provides a new outlet for the massive amount of steel slag solid waste generated each year, while saving energy, reducing emissions, and adding a significant amount of land resources. Therefore, vigorously developing a circular economy that integrates comprehensive treatment systems of "solid waste utilization - waste gas treatment - by-product transformation of desert land" will provide new endogenous impetus for China's high-quality economic development and offer new directions and ideas for sustainable development in China and beyond, promoting the construction of a community with a shared future for mankind.
