This paper describes our challenge to diffuse desulfurization equipments such as flue gas desulfurization (FGD) plants or bio-briquettes in Shenyang, China. Gypsum, which is a major material in by- product from the desulfurization process or burnt ash of the bio-briquettes, is a key material to remediate alkaline soil. Since alkaline soil is found in typical soil degradation in dry land agriculture, gypsum production from coal combustion has a potential to contribute agriculture land remediation in China. Almost eight years of our efforts confirmed that FGD gypsum can remediate heavily eroded alkaline soil and that the ash of the bio-briquettes can also do it although it contains gypsum only about ten percents. A simple but well performed FGD plant was constructed and attached to an old coal firing boiler. The gypsum from the plant was also confirmed to have high performance in alkaline soil remediation.
