NEWS & MARKET16 NEWS & MARKET AAC WORLDWIDE %u2022 3.2025Currently, Maxcrete Limited produces approximately 35,000 m3 of AAC blocks annually. We currently have the largest production capacity of approximately 1000 m3 per day. However, we are planning an extensive market awareness campaign since it%u2019s a new product for Bangladesh which will allow us to reach at least 240,000 m3per year in the near future. At present, we manufacture AAC blocks exclusively, but we already implemented the technologies and intend to expand our product range to include AAC panels and lintels.We are actively exploring the integration of recycled materials into our AAC production process and we have an in house research and development laboratory including a water treatment plant inside our facility. In particular, we aim to utilize fly ash and recycled AAC waste. While fly ash is not currently widely available in Bangladesh, several coal-based power plants are being established, which will provide fly ash as a byproduct of coal combustion. This will not only help reduce industrial waste but also lower carbon emissions compared to traditional clay brick manufacturing.Additionally, during transportation and installation, sometimes AAC blocks may be damaged or broken. These can be crushed and processed into aggregates, which are then reintegrated into the production cycle for new AAC blocks %u2013 significantly reducing the demand for virgin raw materials.To minimize energy consumption, Maxcrete has installed a 357 kW solar power system, with plans to expand to 1 MW. Once completed, solar energy will account for 30%u201335% of our total energy use. Furthermore, we have converted our boiler system from diesel to CNG, leading to a projected reduction of fuel consumption by 30%u201335%.Maxcrete employs various energy-saving measures during production. For instance, steam used in the curing process is recycled, and condensate water is reused as preheated feed water for the boiler %u2013 resulting in a 25%u201330% reduction in fuel energy consumption.As for the end product, AAC blocks offer superior thermal insulation due to their low thermal conductivity (0.12%u20130.15 W/m%u00b7K), compared to traditional clay bricks (0.8%u20130.81 W/m%u00b7K). This results in a 25%u201330% reduction in air conditioning energy usage. Additionally, AAC blocks provide enhanced fire resistance (4+ hour rating for 200 mm thickness) versus conventional clay bricks (2 hour max rating). Overall, the widespread use of AAC blocks could contribute to an estimated 30% energy savings, positively impacting the national power grid.Statement from Samiul Islam, Executive Director, Maxcrete Limited
