The application for the patent was published on Dec. 12, under issue no. 50/2025.
According to the abstract released by the Intellectual Property India: "According to the present disclosure, a method for manufacturing synthetic or manmade filler aggregates from waste for construction applications is disclosed. The method comprises the steps of collecting waste plastics from landfills and bauxite residues from industrial processing, obtaining dried bauxite residues by air-drying the collected bauxite residues for a period, mixing the dried bauxite residues and the waste plastic in a ratio for a period to produce a homogenous mixture of waste plastic and bauxite residue, extruding the homogenous mixture by feeding the mixture of waste plastic and bauxite residue into an extruder rotating at a speed while heating the mixture at a temperature to produce a molten mixture of bauxite residue within a waste plastic matrix, and producing synthetic filler aggregates with a particle size by shredding the molten mixture. The present invention provides an economical, sustainable solution and can be utilized for infrastructure, geotechnical and geoenvironmental applications."
