SINERGIA EN LOS PROCESOS DE VALORIZACIÓN ENERGÉTICA DE RESIDUOS PARA EL TRANSPORTE

Abstract

Industrial by-products synergy is pontentially capable of of generating an industrial ecosystem that minimizes waste production..This article presents a case of synergy of a by-product use to product fuel for the transport sector. This sector is selected because the public administration is focused in reducing its fuel consumption. The initial by-product is dairy industry waste. This waste could be seen as a treatment problem, but can also be presented as an opportunity for energy recovery. Thinking on energy recovery, anaerobic digestion is the most suitable alternative. The biogas obtained can be upgraded for use in vehicles. Synergistic processes will be evaluated in order to use the by-products generated. Environmental sustainability analysis will be made using Life Cycle Analysis tool. Carbon Footprint and Energy Ratio tools are also used. This work proposes an industrial ecosystem as closed as possible to minimize the required inputs and waste produced, improving the sustainability of the waste treatment process.
