The aim of this study was to analyse the eco-efficiency of 15 agricultural biogas plants located in Northern Italy. For this, the combination of life cycle assessment (LCA) and data envelopment analysis (DEA) methodologies was considered with the purpose of identifying efficient operational plants...

This study proposes an optimal design method for maximizing the sustainability of an integrated wastewater treatment plant with a combined heat and power generation system. The proposed system is analyzed based on thermo-environ-economic analysis to investigate the effects of the components'...

To decrease the use of fossil fuels and face the energetic demand, the integration of renewable energy is a necessary step. Part of this renewable energy can be supplied by the production of electricity from photovoltaic panels and windfarms. The massive use of these intermittent energies will lead ...

Offshore cultivation of seaweed provides an innovative feedstock for biobased products supporting blue growth in northern Europe. This paper analyzes two alternative exploitation pathways: energy and protein production. The first pathway is based on anaerobic digestion of seaweed which is converted ...

Biogas engineering is an effective method for agricultural waste treatment among many methods. It can recycle on multi-layers and dispose wastes. It is an important department of sustainable agricultural development mode to achieve production capacity, and protect environment. There were many...

Source separation systems for the management of domestic wastewater and food waste has been suggested as more sustainable sanitation systems for urban areas. The present study used an attributional life cycle assessment to investigate the carbon footprint and potential for nutrient recovery of two...

In Argentina, there is an important potential to utilize organic waste to generate bioenergy. This work analyzes the environmental impacts and the energetic and economic requirements of the biogas produced by digesting the sewage sludge (SS) produced in a wastewater treatment plant in a medium city ...

In Taiwan, due to the limited capacity of waste cooking oil, palm oil has been viewed as the potential low-cost imported feedstock for producing biodiesel, in the way of obtaining oil feedstock in Malaysia and producing biodiesel in Taiwan. This study aims to evaluate the cradle-to-grave life cycle ...

Purpose: Greenhouse gas (GHG) emissions resulting from biofuel production and use often occur over many different years. Nondynamic GHG accounting methods traditionally sum the global warming impacts (GWIs) occurring over a 100-year period for all emissions occurring in the life cycle regardless of ...

Economic uncertainties and environmental constraints regarding fossil fuels have encouraged initiatives for renewable energy sources and assessment of their life cycle impacts. Brazil ranks second worldwide in biodiesel production, despite the relatively recent organization of its national chain,...
