China: Huaxin Cement has announced that it burned 2.7t of seized opiates in its fuel mix at its Diwei cement plant in Chongqing. Representatives of the Chongqing Anti-Drug Committee, Public Service Bureau, Eco-Environmental Bureau and Procuratorate were in attendance. Huaxin Cement reports that the dangerous substances have been “safely disposed of.” The producer said that this is the largest single volume of drugs to have been combusted in a cement kiln. The plant previously burnt 1.22Mt of illicit substances in 2018.

China: Huaxin Cement says that it has disposed of 55t of medical waste from coronavirus-infected hospitals in Wuhan province at its 3.4Mt/yr Yangxin cement plant in Hubei province. Xinhuanet News has reported that the plant’s precalciner and rotary kiln have safely processed the batch, from its delivery in sealed trucks, through the combustion of the waste and its packaging, into cement.

China: BBMG has sold its 49% stake in Beijing BBMG Mangrove to Jidong Cement for US$242m. Beijing BBMG Mangrove is principally engaged in the collection, storage and processing of poisonous and hazardous wastes.

China: Researchers at the Hong Kong Polytechnic University have produced clinker by burning fuel containing 20% post-consumer wood-derived fuel (WDF), reducing carbon dioxide (CO2) emissions by 16% compared to the same fuel blend without WDF, at no cost to product quality. VerticalNews has reported that the combustion also emitted mercury, cadmium, thallium and other heavy metals respectively at a rate of 2%, 21%, 6% and 7% of China’s specified limits.

The findings follow research from Tsinghua University aimed at ascertaining the total process-related, direct fossil fuel-related and indirect electricity-related emissions of China’s cement sector. Since the government committed to a reduction compared to its 2005 per capita CO2 emissions of 40 - 45% by 2020 and 60 - 65% by 2030, China’s cement-related emissions peaked in 2014. The research, funded by various Chinese public bodies as well as the Royal Academy of Engineering and the Natural Environment Research Council, indicated that historical emissions growth was driven by economic growth, offset in recent years by improved intensity and efficiency. The outsourcing of cement capacities to less developed regions with less accurate recording methods may have precipitated the trend.

Bio-derived fuels from the growing consumer sector may help China to establish itself as an innovator of green cement solutions.

China: China Shanshui Cement has started a strategic cooperation agreement with China Conch Ventures to jointly develop projects to coprocess industrial solid and hazardous waste at its cement plants. It also covers the joint construction of upstream and downstream industrial chains. The agreement is for plants in Shangdong and the northeast of the country.

China: Huaxin Cement has released an Environment Impact Report for a proposed domestic waste co-processing project at its Huangshi plant in Hubei province. The project will process 3000t/day of waste for the plant’s 2.85Mt/yr production line.

China: CNBM has entered into a joint venture with Conch Ventures to establish a business processing solid waste to support co-processing at its cement plants. The new company will process at least 3Mt/yr of solid waste.

China: In 2018 China Resources Cement launched co-processing projects in Changjiang County in Hainan, Tianyang County in Guangxi, Midu County in Yunnan and Fengqing County in Yunna. Three of these are in trial operation and the Tianyang project is in full operation. The cement producer runs seven co-processing projects overall with other sites at Binyang in Guangxi, Nanning in Guangx and Guangzhou in Guangdong. These process a variety of waste types, including municipal solid waste, urban sludge and hazardous industrial waste.

China: Jidong Cement Fengxiang plant in Tianjiazhuang district in Shaanxi is holding a public consultation before it disposes of 0.1Mt of hazardous waste. The cement company plans to process the waste in its 4500t/day kiln. It says that it can meet environmental regulations during the operation

China: Guangzhou Zhujiang Cement has completed a dry sludge co-processing project at its plant in Shenxian, Baiyun in Guangdong. The plant can process 300t/day of the dry sludge. CNBM Sinoma’s subsidiary Tianjin Cement Industry Design & Research Institute (TCDRI) was the main contractor on the initiative. The project was agreed in early 2016, built in 2017 and then tested from late 2017.
