Methanization of fish waste for the production of renewable energy: prospects for traditionally fried Moroccan fish

Methanization, also known as anaerobic digestion, is an innovative and environmentally friendly approach that reduces and adds value to harmful bio-organic waste.The valorisation of fish waste, especially from traditional fish farming in Morocco, can be achieved by converting this type of waste into biogas, making it a renewable energy source with no ecological impact.In this article, we discuss the theoretical basis of methanization, the different reactor technologies available, the recent advances in the field and the potential uses of the biogas produced.It highlights the benefits of anaerobic digestion of bio-organic waste and the potential applications for fish waste to improve the methanization process and maximise the environmental and energy benefits.
