AAC WORLDWIDE %u2022 2.2025 PRODUCTION TECHNOLOGY 81in real time. For example, sensors adjust steam supply dynamically based on autoclave pressure and temperature, cutting energy waste.Dongyue is also pioneering single-operator factories, where one worker can initiate full production with a single command.Production optimization: Flexibility and rapid responseTo meet customized block and panel demands, Dongyue developed smart mould systems for quick product specification changes, enabling 48-hour order turnaround. Future integration with automated logistics and AI-driven warehousing will further reduce inventory and expedite deliveries.Challenges of traditional large AAC plantsLarge AAC plants (annual capacity >300,000 m%u00b3) face hurdles in sparsely populated, resource-scarce, or underdeveloped markets:%u2022 Limited and volatile market demand: Largefactories face unstable construction marketdemand, leading to idle capacity and surgingmarginal costs. This makes it challenging tosustain the break-even point for such plants.%u2022 Supply chain bottlenecks: AAC production relieson centralized raw material supplies (e.g., silicasand, cement, lime). In remote regions, transportation costs can exceed 40% of total materialexpenses, exacerbating logistical challenges.%u2022 Energy infrastructure weaknesses: Insufficientlocal power or natural gas infrastructure oftenforce production cuts due to energy shortages,further straining operational efficiency.%u2022 Market mismatch: Poor market alignment arisesfrom the conflict between product standardization and diverse demands. Large factories thatprioritize efficiency typically produce uniformspecifications, whereas sparsely populatedregions often require customized dimensions (e.g., non-standard blocks tailored to traditional architectural structures), resulting in excess inventory.%u2022 Logistics costs: Long-distance transportationcosts erode profits. If a factory is located farfrom the end market, the logistics costs for AACproducts may exceed the product%u2019s own value.As a consequence of the above considerations, large plants are not universally viable, as they may be related to high investment costs and low returns.The Mini AAC Factory solutionDongyue targets niche markets with mini AAC plants (annual capacity: 10,000 - 60,000 m%u00b3), lowering upfront costs and shortening payback periods.Core advantages of Mini AAC Factories%u2022 Cost-effectiveness: Low upfront investment andflexible operations. The entry barrier is reducedby 50%: A mini AAC production line requires onlyRMB 7%u201315 million (appr. 1-2 million EUR), andDongyue Multifunctional Cutting Line for large AAC plants.Production plant type Annual production(m3/year) Equipment selection%u00a0Mini Plant 30,000-60,000 DY2.4x1.2x0.6mDY3.0x1.2x0.6mDY3.6x1.2x0.6mMedium Plant 150,000-300,000 DY4.0x1.2x0.6mDY4.2x1.2x0.6mDY4.8x1.2x0.6mLarge Plant 300,000-500,000 DY5.0x1.2x0.6mDY5.4x1.2x0.6mDY6.0x1.2x0.6mVery Large 500,000-1,000,000 DY6.0x1.5x0.6mDY7.2x1.2x0.6mDY7.5x1.2x0.6mTable 1: Dongyue AAC plant portfolio
