MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202521092533 A) filed by Vivek Ramesh Sharma, Bhiwandi, Maharashtra, on Sept. 26, 2025, for 'method for manufacturing of denim fibre board using post-consumer denim waste.'
Inventor(s) include Vivek Ramesh Sharma; Dr. Pramod Belkhode; and Dr. Prashant Washimkar.
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: "This invention presents a novel method for manufacturing denim fiber boards from post-consumer denim waste. The process begins by collecting and cutting denim pants into smaller pieces, which are then shredded into finer particles using a shredder machine, as shown in These fine denim fibers are mixed with bio-based adhesives, such as gum arabica, tannin, or corn starch, in a 1:1 ratio. The resulting mixture is transferred into a mould with dimensions of 300 x 200 x 25 mm and compressed using a hydraulic press at 7 MPa for 120 minutes to ensure proper compaction. After compression, the denim fiber board is removed from the mould and dried at 120 C for 24 hours to remove moisture. The final product, depicted in Figure 2, is a durable, sustainable denim fiber board with tensile strengths ranging from 1.5 to 5.8 MPa. This innovative method provides an eco-friendly alternative to traditional materials by recycling post-consumer denim waste."
