Every year, large amounts of shrimp waste are disposed in the environment, causing serious environmental problems. The prospect recycling helps to reduce and protect environment. In this study, three different species were used, including Pleoticus muellieri, Litopeneus vanamei, Parapenaeus longirostris, separated into shells (PLMUS, LIVAS, PALOS) tails (PLMUT, LIVAT, PALOT), transformed novel carbonaceous materials. Their adsorption properties investigated using chemical compounds (MB, MR, phenol, astaxanthin) aqueous means. materials characterized through FTIR, BET, SEM–EDS analyses. According results, adsorbents presented high percentage MB astaxanthin (>90%), low phenol owing bonds that formed between functional groups organic substances corresponding on surface results FTIR analysis show presence C=C from aromatic rings adsorbed MR at 1636 cm−1, O-H phenols 3330 or C=O 1730 cm−1 after astaxanthin. BET analysis, increase specific area follows order: LIVAS > PLMUS PALOT PALOS PLMUT LIVAT. compact structures with main elements C (37–56%), O (25–35%), Ca (12–23%) for all Kinetic showed experimental data can be best described by pseudo-second order model, indicating chemisorption is prevailing mechanism. Consequently, such methods promote sustainable management zero-waste fish farming practices, fostering production high-added value not only decontamination purposes but also isolation bioactive substances.
