Concrete brick and block manufacturers across Bangladesh are facing a severe crisis due to inadequate government support and limited use of eco-friendly materials in public and private construction projects. Despite a 2019 government plan to phase out traditional clay bricks and fully adopt concrete blocks in public works by the 2024–25 fiscal year, production and use of clay bricks continue nationwide, harming both the environment and investors in sustainable industries.

Entrepreneurs and environmental officials say that concrete blocks, produced with modern technology using stone chips, Sylhet sand, and high-quality cement, are durable, heat- and sound-resistant, and environmentally safer. However, many factories are struggling or closing due to lack of policy enforcement, awareness, and incentives. Local engineers and business owners note that using hollow and uni blocks reduces construction costs, time, and maintenance expenses while improving durability.

Environmental experts warn that without stronger policy execution and incentives, Bangladesh may fail to meet its sustainability targets and risk discouraging future investment in eco-friendly construction materials.
