Gross energy requirement during the life cycle of a building is a growing research field. The embodied energy calculation and its planning having significant role on optimization the total energy used in the building. Recycling of industrial waste materials to reduce the embodied energy is a sustainable approach to mitigate climate change and global warming. This paper discusses the quantification of indirect embodied energy consumption for recycling solid waste, such as granulated blast furnace slag (GGBS) in the brick making process, representing state of the art technology towards sustainable development. Traditional burnt clay brick consumes a huge amount of energy per brick itself. Due to the shortage of traditional resources and keeping in mind energy conservation, we felt we could re-use industrial process wastes, and contribute towards sustainable development. It may be noted herein that re-using industrial waste in construction materials has-been gaining great prominence around the Globe. GGBS is one of the few industrial waste products, which could be used as a construction material through multiple processing layers. In this study, we experimented with brick preparation by using GGBS with cement as a binder. The mechanical property of the sample, such as its compressive strength, is promising, ranging between 13.18MPa–25.48 MPa. The process does not require sintering the material; therefore, it helps in reducing the generation of CO2 and other greenhouse gas (GHG), most importantly, it is almost carbon neutral. Energy consumption for preparation of brick by using GGBS calculated and makes comparison with the process of burnt clay brick, which found beneficial in respect of energy conservation, environment, and sustainability. The study reveals that recycling GGBS for production of brick having significant potential for reducing indirect embodied energy in the building. The Construction and building sector can benefit from using GGBS for brick processing.
