Abstract

The extensive consumption of fossil fuels, the inflation of crude petroleum price and the environmental-political pressure drive industrial world towards green fuel, such as biomass and waste, and imply noteworthy environmental and social advantages. This study is focused on anaerobic digestion (AD) of the waste (300 t/y in 2015) generated by a L’Oréal plant located in Turin area. Four residues, combined in a mixture according to their relative abundance, were considered: sludge from wastewater treatment plant (WWTP), residues of shampoo and conditioner, sludge from mascara production and food waste from the canteen. All waste is characterized by a low biodegradability and 44%-wt is classified as hazardous because of the high organic content (CODtot 624÷1436 mg/g), and therefore it is now incinerated. The aim of the research is the evaluation of the technical feasibility of AD of unaltered and pre-treated (to enhance methane yield) waste mixture. The novelty of the approach is the implementation of AD in a usual industrial context (personal care and make-up production) as a key-practice to improve the sustainability of the overall productive process.
