| Objective on the basis of need | • To develop a novel biomass-based slurry/suspension for the beneficiation of recycled aggregates using a low-energy process. • To characterize the microstructural, physical, and mineralogical characteristics of surface-modified recycled aggregates • To assess the effect of the novel beneficiation method on the fresh, mechanical, and durability characteristics of recycled concrete systems made with surface-modified recycled aggregates. • To conduct an environmental and economic cost-benefit analysis using LCA and LCCA and assess the viability of the technology. |
| Executive summary of the proposed project (In 250 words) | India generates approximately 530 million tonnes of construction and demolition (C&D) waste annually, with less than 5% recovery rate. The majority of this waste ends up in landfills, contaminating soil and water. However, C&D waste can be sustainably recycled and used in new construction, reducing the burden on natural aggregates. The incorporation of recycled aggregates (RA) in construction poses challenges due to inconsistencies in quality. Existing recycling processes are energy-intensive, and surface treatment techniques are being explored to improve RA characteristics. One promising method is using bio-mass slurries/suspensions for surface beneficiation. This proposal aims to develop a sustainable method for surface beneficiation of RA using bio-mass ash slurry and siliceous-alkaline suspension. The study aligns with the waste-to-wealth concept and may contribute to the livelihood of marginalized farming communities. The technology has the potential to: - Enhance the quality of RA - Reduce the environmental impact of C&D waste - Provide an additional income source for farmers - Contribute to sustainable construction practices The proposed research will investigate the feasibility of using bio-mass ash slurry for surface beneficiation of RA, paving the way for a more sustainable and circular construction industry. |
