Nasaki is one of the pioneering companies in the field of green building materials manufacturing in Vietnam, with its core technology being the production of non-fired paving bricks using advanced wet pressing technology from Japan. Unlike traditional kiln-fired methods, which consume significant amounts of energy and emit large quantities of CO₂, Nasaki has chosen a path of innovation aligned with sustainability. By utilizing fly ash, stone powder, and recycled materials, the company has developed a range of bricks with diverse colors and high durability that meet the technical requirements of large-scale construction projects while remaining environmentally friendly.
Nasaki’s technological development journey extends beyond the adoption of wet pressing technology. It is also reflected in the company’s efforts to optimize its production processes toward greater energy and resource efficiency. Instead of relying on fossil fuels, Nasaki has transitioned to using recycled oil and is gradually integrating solar power into its operations. Water and electricity consumption during production have also been significantly reduced through circular solutions and automation. According to internal estimates, Nasaki‘s model reduces CO₂ emissions by 33% to 39% compared to traditional manufacturing methods—an impressive figure in an industry often labeled as “carbon-intensive.”
In addition to its green technology, Nasaki has demonstrated strong market capabilities by supplying products for large-scale projects such as Ocean Park, Vinhomes Smart City, and various resorts in Sa Pa. With an annual production capacity of 5.5 million bricks, the company has built a stable and reliable operational system, showcasing a harmonious integration of advanced technology and supply chain management. As the market increasingly favors environmentally responsible solutions, Nasaki‘s success stands as proof of the commercial potential of sustainable initiatives when developed in the right direction.
Moreover, by participating in the P4G Vietnam Summit 2025, this startup not only promoted its production model to international partners but also opened doors for technology transfer, manufacturing collaboration, and international market expansion.
Compared to conventional kiln-fired bricks, Nasaki’s products simultaneously address three major issues: air pollution from emissions, resource wastage, and high energy costs. Traditional bricks require large amounts of wood, coal, or gas to reach high temperatures, resulting in substantial emissions. In contrast, Nasaki’s non-fired solution eliminates the firing stage entirely, repurposes industrial waste like fly ash, and produces bricks with equal or superior quality. While other non-fired brick technologies often fall short in terms of durability or color variety, Nasaki’s wet pressing method allows for precise molding, strong adhesion, and a wide range of colors—an advantage for architectural projects with high aesthetic standards.
Nasaki is a prime example of the innovative capacity of Vietnamese enterprises in the building materials industry. When technology is developed in response to real-world needs and paired with a circular mindset, the challenge of sustainable development can indeed be addressed through the internal strengths of local startups.
