Steel slag-turned soil conditioner changes saline-alkali land into fertile farmland
By Dou Hanyang, Zhang Jinke
With the help of a drone, a herdsman driving a harvester followed navigation system to an alfalfa grassland that covers an area of over 300 mu (20 hectares) on a vast expanse of saline-alkali land in Xianfeng township, Urad Front Banner, Bayannur city, north China’s Inner Mongolia autonomous region.
The grassland, which used to be barren saline-alkali land, is a pilot and demonstration project for saline-alkali wasteland transformation. It has been turned into fertile farmland by soil conditioner made from an iron and steel plant’s desulfurization byproducts.
Baogang Group, an iron and steel enterprise headquartered in Inner Mongolia, produces over two million tons of steel slag every year. The steel debris it has accumulated over the years has piled up like a mountain, not only occupying land resources, but polluting the air.
To dispose of steel slag, a subsidiary of Baogang Group introduced a desulfurization project developed by Taiji Environmental Protection Equipment Co., Ltd., a private technology enterprise based in Cixi city, east China’s Zhejiang province, which removes sulfur dioxide from flue gases with steel slag.
The project can consume 7,000 tons of steel slag every year, and the nearly 10,000 tons of byproducts from flue gas desulfurization (FGD) can be used to produce soil amendments.
At the factory of the subsidiary of Baogang Group, the chimneys of three 75-ton circulating fluidized bed (CFB) boilers equipped with desulfurization devices soar into the sky.
According to an executive of the company, steel slag is ground first, and the powder is added with water and then sent into the desulfurization tower. After a series of chemical reactions, the desulfurization byproducts become sources of soil amendments.
Unlike waste generated by iron and steel plants, which are hard and rough large particles, FGD byproducts are fine powder and feel like wet soil. Based on the properties of different patches of land, technicians then add suitable microelements into these FGD byproducts, eventually creating soil conditioners.
“Saline-alkali soil is formed as salts are kept within. After soil conditioners made from FGD byproducts are added into saline-alkali soil, they replace ions in the soil, including potassium, sodium, magnesium ions, with their own chemical elements such as calcium and iron, which makes it possible to take the salts away from the soil with water later,” said Shi Yuezhan, general manager of Taiji Environmental Protection Equipment Co., Ltd.
The company has also taken measures to ensure that the desalted soil will not be affected again by the salts contained underground and in the surrounding land, according to Shi.
“After the salinity in the soil is reduced, crops can grow on the land,” Shi explained.
Stressing that solid waste disposal shouldn’t risk generating new waste, Shi believes it important to form a green chain to truly realize circular economy.
Replacing traditional desulfurizer such as limestone and lime with steel slag in desulfurization can not only save limestone resources, but avoid carbon dioxide emissions during the production of lime, according to Shi.
If a project that produces 21,500 tons of sulfur dioxide per year uses steel slag as desulfurizer, it can save 26,000 tons of lime and reduce carbon dioxide emissions by 11,400 tons a year. Its exhaust will also be able to meet China’s ultra-low emission standards.
Taiji Environmental Protection Equipment Co., Ltd., one of China’s national-level “little giant” enterprises that focus on specialization, refinement, uniqueness and innovation, has reaped the rewards of innovation through continuous input into research and development (R&D).
The company spends over four percent of its annual revenue on R&D every year. Last year, the proportion was raised to 6.6 percent. Research personnel in the enterprise has always accounted for more than 30 percent of its employees; and 12 R&D achievements of the company were put into commercial use in the past two years.
Technological accumulation has enabled the company to expand its self-developed technologies from the desulfurization technology using steel slag to energy recycle system, and helped draft the technical specifications for the adoption of steel slag in FGD.
The number of national-level “little giant” enterprises has reached 30 in Cixi. While making independent innovation the driving force for their development, these companies have endeavored to increase the commercialization rate of scientific and technological innovations and translate advances in science and technology into practical productivity.
“In the coming years, we will continue increasing R&D investment and enhancing support for our fund for R&D of eco-friendly technologies so as to encourage research personnel to carry out technological innovation and new product development and further accelerate the commercialization of scientific and technological achievements,” Shi said.

‘Ombugadu Is a Brand, Not a Title’ — PDP Chieftain
By Emmanuel Kuza
A chieftain of the Peoples Democratic Party (PDP) in Nasarawa State, Abuga Ovie, has described the name Ombugadu as a political brand, saying the popularity and wide acceptance of the name have made David Emmanuel Ombugadu a major force in the state’s political landscape.
Ovie, who stated this in an interview on Tuesday, said what started as opposition from some of Ombugadu’s biological brothers and people he described as fathers and uncles who betrayed him for personal political interests had now assumed a wider dimension, with political parties allegedly joining the battle against him.
According to him, the latest development was an attempt to undermine the political value of the Ombugadu name by presenting another person with the same surname, describing it as an indication of how far some political actors were prepared to go to weaken the PDP governorship candidate.
“Ombugadu is a brand, not a title. The people are not fools. They know their own. You cannot simply bring another person bearing the same name and expect the people to forget the political identity that Ombugadu has built over the years,” he said.
He further alleged that a former governor was working to introduce a political associate who had served as Accountant-General of Nasarawa State into the political equation, with the alleged objective of destabilising the PDP and weakening its chances by ensuring that the party fields a less competitive candidate in 2027.
“The plan, as we understand it, is to destabilise the PDP and make sure the party presents a weak candidate, thereby creating an advantage for the former governor’s preferred candidate. But all those efforts have proved abortive because the national leadership of the PDP stood its ground and refused to lose its best bet for the 2027 governorship election,” Ovie said.
The PDP chieftain said the resolve of the national leadership to retain Ombugadu had demonstrated the confidence the party had in his capacity to win the governorship election, despite what he described as attempts by some political actors to frustrate his ambition.
Ovie urged political parties and their leaders to resolve their internal differences instead of concentrating their efforts on Ombugadu, whom he compared to David in the Bible, saying he remained focused despite betrayal and opposition from those close to him.
“Ombugadu is like David in the Bible. Even when his brothers forsook him, he remained focused. Today, despite the people who have betrayed him, he remains focused and has a blueprint that can rescue Nasarawa State,” he said.
He said political parties should concentrate on presenting their programmes and convincing voters about how they intend to address the challenges confronting the state rather than expending their energy on attempts to stop Ombugadu.
“Political parties should fix their problems instead of wasting their strength fighting Ombugadu. Let everybody bring their blueprint before the people and explain what they intend to do for Nasarawa State,” he said.
Ovie maintained that the 2027 election should be about ideas, competence and the future of Nasarawa State, rather than attempts to manipulate political structures or undermine individuals perceived to enjoy strong grassroots support.
He urged the people of the state, particularly the Eggon community, to remain politically vigilant and resist what he described as efforts to make them settle for less, insisting that voters would ultimately determine who enjoys their confidence at the polls.

SCUML, REDAN Strengthen Collaboration on Anti -Money Laundering Compliance
By Francis Wilfred
The Special Control Unit against Money Laundering (SCUML), and the Real Estate Developers Association of Nigeria (REDAN) have expressed commitment to ensure a full compliance with the Anti Money Laundering/Counter Finance on Terrorism/Counter Proliferation Financing, (AML/CFT/CPF) laws within the Nigeria’s real estate sector.
They made the resolve during a stakeholders’ engagement held on Thursday, September 10, 2026
The engagement focused on Mutual Evaluation readiness, risk-based supervision, beneficial ownership transparency, customer due diligence, internal controls and stronger collaboration between SCUML and the real estate sector.
Assistant Commander of the EFCC, ACE 1 Ibinabo Amachree, speaking on behalf of SCUML highlighted the strategic role of real estate operators in protecting the integrity of Nigeria’s financial system, particularly given the sector’s vulnerability to money laundering and other financial crime risks.
Amachree encouraged REDAN members to move beyond registration to ensure that compliance is embedded in their day-to-day operations. He mentioned the areas to include: understanding institutional risks, knowing customers and beneficial owners, identifying politically exposed persons, conducting appropriate sanctions screening, maintaining effective internal controls and meeting applicable reporting obligations
He, therefore, reaffirmed readiness to working closely with REDAN and other stakeholders to improve compliance, build capacity and promote a stronger culture of accountability across the real estate sector
“The message is clear: effective compliance is not just about meeting regulatory requirements; it is about protecting businesses, strengthening the real estate sector and safeguarding the integrity of Nigeria’s financial system”, she said.
In his remarks, the Chairman of REDAN, Lagos state, Mr Tony Kolawole pledged readiness to partner with SCUML in ensuring compliance with AML/CFT/CPF in the real estate sector to uphold financial integrity.
The engagement also provided an opportunity for REDAN members to share practical regulatory and operational challenges affecting the sector, reinforcing the importance of continuous dialogue between regulators and industry stakeholders.
