“…Regarding the conventional substrates, the organic fraction of municipal solid waste (such as kitchen waste, garden waste [6], or fruit and vegetable waste [7]) is one of the most used substrate types, and it has been extensively evaluated, along with a Energies 2023, 16, 4555 2 of 18 variety of agricultural waste streams, such as manure [8], olive mill wastes [9], and corn silage or other lignocellulosic materials [10]. On the other hand, alternative and innovative substrates, such as used disposable nappies [11] or the prunings from several plants (e.g., Hippophae rhamnoeides [12] and Opuntia ficus [13]), have also been assessed in recent years to evaluate their methane yields. Theoretically, 1 g of the volatile solids (VS) of carbohydrates, proteins, and lipids can produce 370 NmL, 740 NmL, and 1014 NmL of CH 4 , respectively, through AD.…”

Considering the current geopolitical situation that has hindered the gas supply gas from Russia, Europe’s main supplier, it is necessary to find alternative routes to guarantee the Italian gas stocks in winter at a reasonable cost. Such energetic strategies should consider the environmental sustainability of the different available options, fitting the targets of the EU environmental policy. With the aim of supplying a quantitative tool to support the European green transition, this paper reports the entire life cycle assessment (LCA) of three different options for the production and supply of natural gas/methane in Italy: the production of biomethane from biogas (considering a real-scale plant in Italy), the use of liquefied natural gas (LNG) supplied by Qatar by vessel, and the use of compressed gas delivered from Algeria via pipeline. The application of the LCA standardized method allowed for the quantification of the environmental benefit provided by the first option, against all the considered impact categories, thanks to a combination of several advantages: (a) its low-impact anaerobic production, (b) its exploitation of a waste product from the food/agriculture industries, and (c) its production of valuable by-products, which can be considered environmental credits. The results proved the possible environmental gain resulting from an integrated energy supply system that would be able to enhance the economic fabric of specific areas.
