The scale-up remains a complicated operation that affects the transition to an industrial scale. The main objective of this study was to examine the pilot-scale deproteinization of Sardina pilchardus scales waste by alkali treatment. Initially, a scale laboratory experiment was carried out to determine the optimal deproteinization condition of Sardine waste. The alkali treatment was found to be effective in the deproteinization of sardine wastes. Deproteinization optimum condition (4±1.5mg/g sample) was recorded with a material-solution ratio of 1:10. This optimal condition was then used to process the sardine scales waste at a pilot scale. The lab-scale and pilot-scale reactors investigation has been conducted on batch processes. The deproteinization of fish waste was then demonstrated on a pilot-scale (2Kg scales), resulting in protein content of 2±0.10mg/g sample and hydroxyproline content of 0.21mg/g sample. Those results indicated that the pilot-scale experiment showed similar performance deproteinization to the lab-scale one. We can conclude that the deproteinization operation is validated at the pilot scale since it can be reproduced without quality and yield losses. The fish scales waste could then be potentially useful as raw substrates for value-added products such as collagen, gelatin, and chitosan.
