Abstract

Whole-site emissions of methane and nitrous oxide, from a combined dry anaerobic digestion and composting facility treating biowaste, were quantified using a tracer dispersion technique that combines a controlled tracer gas release from the treatment facility with time-resolved concentration...

Abstract

Dairy products are major components of the human diet but are also important contributors to global environmental impacts. This study evaluated greenhouse gas (GHG) emissions, net energy intensity (NEI), and land use of confined dairy systems with increasing levels of pasture in the diet. A...

Abstract

The present study was primarily aimed at reviewing recent studies on biodiesel production as well as the application of various biodiesel additives including their life cycle assessment studies. More specifically, major factors affecting engine performance and emission characteristics of diesel...

Abstract

The palm biodiesel industry has been promoted for climate change mitigation, energy security and sustainability strategies worldwide. International debates on land use change and unintended consequences from market-driven impacts of biofuel (i.e. biodiesel and bioethanol) production have...

Abstract

Biomethane produced from seaweed is a third generation renewable gaseous fuel. The advantage of seaweed for biofuel is that it does not compete directly or indirectly for land with food, feed or fibre production. Furthermore, the integration of seaweed and salmon farming can increase the yield of...

Abstract

The life cycle assessment (LCA) methodology is increasingly used to ensure environmental sustainability of emerging biofuels. However, LCA studies are usually not performed at the process design stage, when it would be more efficient to identify and control environmental aspects. Moreover, the...

Abstract

Previous life cycle assessments for agro-bioenergy production rarely considered some agronomic factors with local and regional impacts. While many studies have found the environmental and socio-economic impacts of producing bioenergy on arable land not good enough to be considered sustainable,...

Abstract

This study evaluates the environmental impacts of biorefinery products using consequential (CLCA) and attributional (ALCA) life cycle assessment (LCA) approaches. Within ALCA, economic allocation method was used to distribute impacts among the main products and the coproducts, whereas within the...

Abstract

A life cycle assessment (LCA) was applied to assess the environmental load of a prospective local bioethanol (EtOH) production system in Southern Italy by using lignocellulosic Fiber sorghum (FS) feedstock. A two steps analysis was carried out considering: (i) a "cradle-to-farm gate" LCA to...

Abstract

Anaerobic digestion is recognized as a good and promising method for energy recovery from sewage sludge, but it is difficult to select a suitable process from various conventional and emerging technical options. In this study, five processes including mesophilic and thermophilic anaerobic digestion ...
