“…As concerns scenario A, both the FeCl 3 and the activated carbons were excluded from the analysis since their amounts were lower than 1% of the input flows and they were considered not relevant for the whole result. The valuable products, resulting from scenario A (mainly the slow releasing fertilizer, the beverage-grade CO 2 , and the electricity surplus), were enhanced by environmental credits with negative values to quantify the avoided impacts of the primary production [30][31][32][33][34][35][36][37]. The extraction process selected for scenarios B and C was related to methane, and it included natural gas extraction and the further removal of water, hydrogen sulfide, and higher hydrocarbons.…”

“…Some authors have investigated biomethane's LCA via biogas and syngas [29], biomethane vs biohydrogen [30], biomethane as a diesel substitute [31], and LNG vs biomethane [32]. Others have conducted studies and detailed LCAs about biomethane with different plant configurations, substrate mixtures, and CO 2 capture technologies [33][34][35][36][37][38][39][40][41][42][43]. LCAs and environmental analyses have also been carried out for LNG that are, for instance, focused on different re-liquefaction systems [44] or different uses as marine fuel [45,46], bus fuel [47], or truck and heavy-duty vehicle fuel [48][49][50].…”

“…Renewable energy gases such as biomethane are expected to replace natural gas, provided they strictly comply with the quality standards for natural gas, which prescribe maximum levels for various trace chemicals [9]. Biogas is considered one of the most promising alternative renewable fuels, but the raw biogas must be upgraded before it can be used in vehicles or injected into the natural gas grid, and the resulting biomethane must be liquefied to be transported to distant locations [10]. However, in order to sustainably integrate these gases into the current energy mix, their quality must be controlled in terms of their major, minor and trace components in order to maintain the integrity of the infrastructure in which they are burned, transported or stored [11].…”

“…Para permitir identificar quão significativo é o potencial da energia química do biogás, utilizou-se como métrica a distância que pode ser percorrida por um veículo de transporte com capacidade de carga de até 58 toneladas, movido a biometano. A estimativa considerou o custo energético da conversão do biogás em biometano acrescido do consumo de biometano de veículo, i. e., cerca de 0,46 MJ ton elada -1 km -1 , que é o consumo médio estimado do transporte rodoviário (KHAN et al, 2022;MADHUSUDHANAN et al, 2020). Considerou-se a independência de energia elétrica da granja a partir da energia do biogás.…”
