Abstract

Research on the absolute environmental sustainability of biofuels is limited, and no studies to date have focused on the biomass pellet sector. Net environmental-ecological performance models can be used to quantify absolute sustainability in a life cycle approach, and this investigation provided an analysis of them in the context of biomass pellets as a case study. Four models were compared, where two models are based on results expressed in biophysical units, and two are given in monetary units. All the models were applied in a cradle-to-gate perspective for the two types of biomass pellets: pine pellets and peanut shell pellets. Ten environmental categories were investigated, and the results showed that the pine pellets were the best option and closer to an absolute sustainable profile. The problem with monetary-based models is the loss of accuracy in results. However, the communication of the results for non-experts could be based on monetary terms as they express the main findings more simply. To assist different stakeholders we provided recommendations on which model to apply in bioenergy systems.

期刊介绍： Sustainable production and consumption refers to the production and utilization of goods and services in a way that benefits society, is economically viable, and has minimal environmental impact throughout its entire lifespan. Our journal is dedicated to publishing top-notch interdisciplinary research and practical studies in this emerging field. We take a distinctive approach by examining the interplay between technology, consumption patterns, and policy to identify sustainable solutions for both production and consumption systems.
