CSIR-Central Salt & Marine Chemicals Research Institute [CSIR-CSMCRI]: This technology presents an eco-friendly, zero-waste process for selectively extracting R-Phycoerythrin (R-PE) from red seaweeds using Good's Buffer Ionic Liquids (GB-ILs), particularly from the Rhodophyceae class. The process uses a sustainable solvent system, including choline and HEPES, to extract R-PE without contaminating R-Phycocyanin. It also allows for the recycling and reuse of solvents, with the residual biomass being utilized for producing plant biostimulants, phycocolloids, and cellulose. This technology is applicable in industries focusing on natural pigments, bio-based products, and sustainable extraction methods.
