Mexico: Cemex has launched its global waste management subsidiary Regenera. Regenera will be involved in the reception, management, recycling and coprocessing three major waste streams: municipal and industrial waste, construction, demolition and excavation waste (CDEW) and industrial by-products. It will tie in with Cemex’s own cement sustainability initiatives, for instance in its supply of waste recovered from the River Nile to Cemex Egypt’s Assiut cement plant for co-processing as alternative fuel (AF).

Vietnam: Vicem But Son Cement has reported that it now substitutes between 20% and 30% of its fuel with alternative fuel (AF). Viet Nam News has reported that company says that it eliminated 133,000t of CO₂ emissions through AF co-processing in 2021. It has used sewage sludge and industrial waste as sources of AF since September 2019.

Brazil: BNDES, the national development bank, has approved a US$7.4m loan for Votorantim Cimentos to co-process alternative fuels. The funds will be used to adapt the company's industrial units to process industrial waste, tyres and biomass, according to the O Estado de Sao Paulo newspaper. The cement producer is preparing to spend US$13.6m towards modifying its plants at Salto de Pirapora in Sao Paulo and Edealina in Goias.

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.

China: FLSmidth, Sino Environment Engineering Development (SEPTEC) and China Resources Cement (CRC) have signed a partnership to provide pyroprocessing co-processing systems to cement plants. FLSmidth will be responsible for the design, engineering and integration of the integrated waste burning solution, with SEPETC acting as a general contractor.

The agreement follows a project at CRC's Hongshuihe cement plant that took municipal and industrial waste from the city of Binyang in Guangxi. FLSmidth installed a Hotdisc system that could process 300t/day of waste to support the cement plant’s cement production capacity of 3200t/day.

"China's energy intensive industries, such as cement production, are coming under pressure from the government that wants to rebalance the economy towards a less energy-hungry mode of growth, curb pollution and reduce carbon emissions. CRC plans to initiate several similar municipal solid waste co-processing projects for other cement producers with FLSmidth and SEPETC as partners," said FLSmidth China Country Manager, Cyril Leung.

In China's latest five-year plan, the government encourages more cement producers to co-process municipal solid waste in the cement industry, with an aim of getting 15 - 20% of the cement kilns in the country to be co-processing waste by 2020. In 2017, China will introduce a national carbon-trading scheme in 2017.
