<![CDATA[Concrete manufacturing significantly contributes to carbon emissions and large consumption of energy resources. Demand for concrete is increasing in developing countries such as China and India, while in some developed countries demand is stagnant or even declining. Every year, the global concrete industry generates a large amount of waste and uses a huge amount of raw materials. While they can reduce costs and recycle waste, sustainable technologies require efficient internal administration and good expertise. Studies show that the use of raw materials and the percentage of recycled materials affect production costs in the concrete industry, which are influenced by several factors. Improving work performance requires an effective sustainability strategy and knowledge management based on internal knowledge. Although awareness about sustainable methods is widespread, there is still a lack of understanding within the concrete sector in Indonesia. To address this, the industry must expand learning opportunities and adopt sustainable practices. PT Wijaya Karya Beton as the largest concrete manufacturer in Indonesia shows this by using metal waste in sustainable concrete, although there are still some obstacles. Increasing demand through policy and awareness can drive technological improvements and the adoption of sustainable practices. As demand increases, the concrete manufacturing industry is bound to develop the necessary technology to meet that demand]]>
