Optimization of a reactor for biostimulant production with emphasis on the economic aspects of hydrolysis

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Biostimulants are increasingly used in agriculture to promote plant growth, improve stress tolerance, and support sustainable farming practices. One common method of production is chemical hydrolysis of protein‐rich waste, such as tannery by‐products, offering an economical and eco‐friendly alternative to conventional raw materials.
