Cement kiln co-processing refers to the use of waste materials (such as industrial waste, municipal solid waste, waste plastics, waste oils, etc.) as alternative fuels, which are fed into the cement kiln for incineration alongside traditional fuels like coal.

Advantages of SID solution
- Improved combustion and thermal efficiency.
- Reduced chlorine and sulfur-containing substances, extending kiln life.
- Optimized alternative fuel composition, reducing temperature fluctuations, and suppressing the generation of most harmful by-products.
- Materials such as slag and sludge, after treatment, can be used as cement raw materials, improving resource utilization and reducing dependence on natural resources.
Processed materials
Industrial solid waste, municipal solid waste, biomass, textiles, rubber and plastics, etc.

Municipal solid waste, alternative fuel disposal system
Through multiple processes including shredding and screening, waste is treated to achieve both resource recovery, and energy production. This not only efficiently handles waste but also enhances energy efficiency in cement production and reduces environmental pollution.

SIDSA focuses on technological research and innovation in the field of waste pretreatment
Back in 2019, when Shanghai first implemented mandatory waste sorting, the entire Chinese internet was baffled by "dry" and "wet" waste. Yet, just a few years later, the topic seems to have faded from public discourse. It's not that we've forgotten, nor that the policies have been halted. The reality is that China's waste treatment technology has quietly achieved an incredible, unforeseen victory.
From February 4 to 6, SIDSA made its debut at the Asia Enwast Expo (Asia Environment & Waste Management Expo) in Bangkok, Thailand. At the exhibition, we engaged in substantive technical discussions with clients from Thailand and neighboring countries, with conversations consistently centered on how to ensure long-term stable operation of equipment under tropical working conditions.
In February 2026, during Indonesia's National Health and Safety Month, SIDSA China Chairman Pierre Jean Charnay was invited by Indocement and Heidelberg Materials to attend a conference in Jakarta. The discussions focused comprehensively and pragmatically on the safety challenges and developments within the solid waste treatment process.
