The potato wastes constitute a major environmental concern due to their significant production in the potato processing industry. Due to their high organic content, this waste can constitute a very interesting Algerian resource for biofuel production. The objective of this study is the energy recovery of an industrial agro-food waste to produce bioethanol. This waste is a solid residue of chips manufacturing and mainly consists of potato starch. The conversion of this biomass was achieved using a chemical pretreatment with hydrochloric acid. The acid hydrolysis of potato starch with a ratio of material to acid solution of 1:2 (w/v) was enough to liberate a high amount of fermentable reducing sugar (159.3 g/l) contained in the potato waste. The hydrolysate obtained at the end was fermented using Saccharomyces cerevisiae yeast under the following conditions (pH 5, 30 degrees C, 100 rpm). The maximum yield of bioethanol (54.12 g/l) was achieved after 116 h. Thus, operating conditions used for the sugar fermentation were favorable and did not exhibit any sort of process inhibition. The Gompertz model was applied to experimental data, and kinetic fermentation parameters such as maximum ethanol concentration (P-m = 49.81 g/l), production rate (r(pm) = 0.87 g/(l h)), and lag phase (t(L) = 5.29 h) were accurately estimated. Those parameters can be used to investigate the economical feasibility for such industry. The results demonstrate that potato starch (by-product of the potato industry) has a great potential for bioethanol production.
