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.

China: Anhui Conch’s Xing'an cement plant in Guangxi region has commissioned a municipal sold waste (MSW) project. The project was started in late 2017 and it has had investment of US$19m. It is intended to process 100,000t/yr of MSW and 49,500t/yr of sewage.

China: China Resources Cement has completed a hazardous waste co-processing project in the Changjiang Li Autonomous County of Hainan. The unit started operation in early February 2018 and it has a processing capacity of 100t/day.

China/Taiwan: Taiwan Cement plans to invest in the Chinese waste recycling market by bidding on projects with local company Beijing Orient. TCC International, a subsidiary of Taiwan Cement, is to select one of its plants in China as the pilot site for the cement kiln project, according to the Taipei Times. The company has set a long-term capacity target of processing 10Mt/yr of waste that is expected to generate over US$688m of profit. At present its plant in Guizhou has an input capacity of 200t/day.

Netherlands/UK: N+P Recycling says that it views a Chinese import ban on plastics as an opportunity for its business. As the Dutch company offers a variety of waste derived fuels for various applications it is encouraging companies to split both fractions to get the optimal waste solutions for each individual quality. Lower calorific value (CV) products are better suited to waste incineration plants whilst higher CV products are typically used by cement, lime, steel and power plants.

Lower grade materials, typically within an 8 - 12GJ/t range, are supplied within many of N+P’s long-term supply contracts, to users within the UK and within Europe. There are also a number of possibilities for materials that are in-between the standard refuse-derived fuel (RDF) and solid-recovered fuel (SRF) qualities, or mid-CV range (12 - 16 GJ/t). For higher quality materials, N+P has a number of solutions all focused on the replacement of primary fossil fuels such as coal.

N+P Recycling produces a higher CV waste fuel product called Subcoal. It is currently building a Subcoal plant at Teesside in the UK with a production capacity of up to 0.22Mt/yr. It has started to source and contract non-recyclable waste streams such as materials recovery rejects, industrial residues and plastic residues for unit. It is expected to open in the third quarter of 2018.

China: Huaxin Cement built three co-processing projects for its cement plants in 2016. It also signed contracts to build 10 new projects and six new projects were under construction. The cement producer said in its annual report that it had 25 co-processing projects operating or under construction with a capacity of 5Mt/yr. It added that its waste disposal per tonne of clinker production was ahead of its competitors in the sector. It noted that its had increased its usage of alternative fuels in the second half of the year following an increase in the cost of coal. Huaxin Cement, like other Chinese cement producers, has been actively enacting government-promoted supply side reforms following a poor market in 2015.

China: Dongwu Cement has struck an agreement with Suzhou Dongfang Jiujiu Industry to start a waste disposal company to supply alternative fuels for its kiln. The cement producer based in Wujiang City, Suzhou Prefecture and its partner will invest US$7.3m in the joint venture to start with, according to the ET Net News Agency. Dongwu Cement will own a 52% share in the company.

It will co-process urban sludge, organic waste and industrial solid waste. It will also collect, store and dispose of soil for soil remediation. It is expected the company will dispose of 50,000t/yr of industrial solid waste.

Dongwu Cement operates a 0.75Mt/yr cement plant with two grinding mills, giving it a cement production capacity of 1.64Mt/yr. It manufactures 42.5 and 32.5 class Ordinary Portland Cement.
