Evaluation of the Effect of the Application of Combined Pretreatments and Inoculum with High Alkalinity on Food Residues Through BMP Tests

The management and control of food waste is currently seen as a growing concern; anaerobic digestion promising alternative for the valorization waste. This study evaluates effect application three pretreatments (grinding, pH control, thermal treatment) organic load employing high alkalinity inoculum methane production through BMP tests, using Taguchi L8 experimental design 4 factors 2 levels, resulting in best performance (65.91 NmL $$\cdot$$ g $$^{-1}$$ TVS) with pretreatment conditions grinding fine particle size, 11, at 60 $$^{\circ }$$ C concentration 14 TVS L , which represents an improvement 34.66% comparison without pretreatments.
