FL Smidth technology for cement plants to burn waste in China

FL Smidth, China Resources Cement and Sino Environment Engineering Development have developed technology to burn urban and industrial waste for Chinese cement production.

To support the city of Binyang, located in the Guangxi region of southwest China, in its efforts to reduce the city’s urban and industrial waste, China Resources Cement and FLSmidth joined forces to come up with a solution for CRC’s Hongshuihe cement plant.

FL Smidth installed a pyro co-processor at China Resources Cement’s Hongshuihe cement plant to economically process raw waste characterised by high moisture and low burn value.

The Hotdisc consumes 300 tons of waste per day to maintain the Hongshuihe plant’s daily production of 3,200 tons cement.

China Resources Cement and FL Smidth have a partnership, together with Sino Environment Engineering Development Co as a general contractor, to roll out the solution to other cement producers in China.

FLSmidth is responsible for the design, engineering and integration of the integrated waste burning solution.

China’s waste mountain
China’s waste problem is growing. Among the 600 biggest cities in China, more than a third battle with serious groundwater pollution due to waste disposal. In the suburbs, several hundred million tons of urban household waste, municipal sludge and industrial waste are left untreated in landfills, increasing at an annual rate of around 8%.

Cyril Leung, country manager, FL Smidth in China, says: “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.”

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. About 4.3 billion tons of cement was consumed globally in 2014, causing global cement production to contribute around 5% of global CO2 emissions. China alone produces 60%.

China Resources Cement is one of China’s leading cement enterprises and owns approximately 40 cement lines in mainland China. Headquartered in Hong Kong, CRC is part of the state-owned enterprise China Resources Group.
