Cultivating perennial grasses on abandoned cropland for bioenergy production is a promising option to meet future renewable energy demands at lower risks for food security and environmental degradation. Studies on the potential environmental impacts of perennial grasses mostly focus on specific...

In the life cycle assessment of bioethanol processes under choline chloride/urea (DES-U), choline chloride/lactic acid (DES-LA) and sodium hydroxide (NaOH) pretreatment studied. As the net energy values under DES-U, DES-LA pretreatment was negative, which were - 4,107,023 MJ and - 643,449 MJ,...

Energy crops for biofuel production, especially switchgrass (Panicum virgatum), are of interest from a climate change perspective. Here, we use outputs from a crop growth model and life cycle assessment (LCA) to examine the global warming intensity (GWI; g CO₂ MJ^-1) and greenhouse gas (GHG)...

The number of micro-scale spirit distilleries worldwide has grown considerably over the past decade. With an onus on the distillery sector to reduce its environmental impact, such as carbon emissions, opportunities for increasing energy efficiency need to be implemented. This study explores the...

Biomass torrefaction is a promising method for carbon-neutral solid biofuel production. The economic feasibility and environmental pollution potential of the torrefaction operation are of great concern to developing a sustainable energy system. In this study, spent coffee grounds are selected as...

To explore the economy and substitutability of agricultural waste-based liquid fuel in the whole life cycle, this paper takes ethyl levulinate as the study object, creatively designing the system boundary and establishing the economic analysis model for the preparation of liquid fuel from biomass...

Rising global prices, increasing energy demand, and increasing greenhouse gas have led to the use of biodiesel fuel. Biodiesel fuel is a suitable alternative to diesel in diesel engines. Therefore, it is critical to analyze the economic aspects to decrease the cost of biodiesel production by...

The handling of multi-outputs in life cycle assessment (LCA) is a controversial topic in both LCA application practice and the literature. Although there is a prescribed hierarchy of how to deal with multi-outputs, which favors system expansion (including co-products and their upstream chains) as...

Purpose : The environmental impacts of breeding industries have been broadly studied and compared. However, environmental research on the rex rabbit breeding industry is scarce. The aim of this study was to evaluate the environmental impacts of two rex rabbit industry chains and verify which one...

This work conducts a life-cycle assessment (LCA) of ethanol production from sugarcane bagasse in the Indian context. A cradle-to-gate system boundary was considered, and a functional unit of 1 MJ of energy from ethanol was used. Eight pre-treatment technologies and four hydrolysis-fermentation...
