Waste to valuable: A replacement of concrete
This research investigates the utilization of waste PET and LDPE plastics combined with pond ash to develop sustainable construction materials. The key innovation is that plastics act as the only binding material, eliminating the need for cement, sand, or water. If used on a large scale, this can bring major environmental, social, and economic benefits.
Self-funded—need to collaborate with industry for field application
A patent titled “Construction Material with Pond Ash” has been filed under the National Institute of Technical Teachers Training and Research, Chandigarh. The intellectual property (IP) covers the composition and thermal-extrusion process for manufacturing cement-less paver blocks using polyethylene terephthalate (PET), low-density polyethylene (LDPE), and pond ash. The future strategy is to convert this patent into a commercial license model to enable technology transfer to small and medium-sized enterprises (SMEs) and municipal bodies for royalty income and wider adoption.
Patent filed with the Indian Patent Office on March 13, 2024, for "Construction Material with Pond Ash," Application No. 202411018668, filed on March 14, 2024, and published on June 20, 2024, in the name of National Institute of Technical Teachers Training and Research (NITTTR), Chandigarh.
Led by a research scholar and an assistant professor from NITTTR Chandigarh, this team combines academic rigor and practical engineering skills to develop eco-friendly building solutions, successfully executing lab-scale work and securing intellectual property.
