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
From December 3 to 5, 2025, SID SA participated as a featured speaker at the Waste Management & Waste to Energy Asia Summit in Jakarta, Indonesia. Under the theme “SID SA's Dual Solution: Turning Waste into Cleaner Energy and Smarter Growth,” we shared practical insights and proven case studies in solid waste treatment systems.
In the future, SID will continue to optimize integrated solutions and refine every piece of equipment, helping more cities and projects achieve efficient resource recovery from bulky waste through stable and reliable production lines. We believe that every shredding and sorting step contributes to making cities cleaner, more energy-efficient, and truly fulfills the mission of turning "waste" into "resources" for discarded furniture.
Many regard waste simply as "discarded items" that can be mixed without consequence. Yet, within waste management systems, household waste is far from worthless—it is a mixture of resources waiting to be unlocked. The purpose of sorting is to reduce waste, increase recycling rates, and alleviate urban environmental pressure.
