ABSTRACT: Fossil fuels drive global warming, necessitating renewable alternatives such as biomethane (or renewable natural gas). Biomethane, primarily produced through anaerobic digestion (AD), offers a cleaner energy solution but is limited by the slow AD process. Biomass gasification followed by syngas methanation has emerged as a faster alternative. This review examines advancements in these processes over t...

ABSTRACT: According to the forecasts projected by European Union (EU) Member States on their respective draft updated National Energy and Climate Plans (NECP) —collected by the European Commission in its report on the first two years of the REPowerEU scheme1—, biogas and biomethane production could reach a range of 30-32 billion cubic metres (bcm) by 2030. Many of these countries have already submitted their up...
Sewage sludge originating from wastewater treatment plants (WWTPs) can be a major cause of environmental pollution and their appropriate management should be viewed as a priority. A critical aspect in sludge management practices is route optimization since significant costs are associated with the transportation of waste. In this work, we propose a heuristic solution based on Clarke-Wright savings method for th...
Em Portugal, a opção de promover a utilização de fontes de energia renovável arrasta consigo benefícios não apenas em termos da prevenção da diminuição dos recursos fósseis e redução da dependência energética, mas também ao nível do desenvolvimento estratégico das economias regionais. A valorização energética dos resíduos orgânicos associados à biomassa é, deste modo, um assunto de grande relevância nos dias de...
