Comparative Life Cycle Assessment

Life cycle assessment of steel production from iron scrap: a case study at a steel plant

Background and Objective: The steel industry is the world's largest consumer of energy. A large amount of iron waste is produced annually, which its use in the steel industry can be economic. The purpose of this study was to investigate the environmental impacts of the steelmaking from iron scrap as a raw material using a life cycle assessment (LCA) method. Materials and Methods: Simapro softw...

Comparative life cycle assessment of biodiesel from algae and jatropha: a case study of India.

Algae and jatropha, two types of promising and unconventional biomass, are investigated in this study for large-scale production of biodiesel. The aim is to evaluate the potential advantages and the magnitude of closeness of life cycle balances between these two biodiesel pathways compared to fossil diesel, by taking into account possible uncertainties. The geographical location of this study i...

World Energy Outlook : a Comparative Study

Differen world energy outlook with different horizons (2035, 2040 and 2050) show that demand for primary energy will increase. The energymix in 2050 will mainly be fossil based although the share of theses fuels will decrease. Accorging to some forecasts, energy consumption will increase more than 50 percent during next 30 years which most of this growth belongs to non-OECD countries. In supply...

Comparative Life Cycle Assessment between Warm Sma and Conventional Sma

This report presents the comparative life cycle assessment (LCA) between warm stone mastic asphalt (SMA) and conventional SMA. Specifically, the study evaluated and compared the life cycle environmental and economic performances of two mixtures: a warm SMA binder course mixture with a chemical additive and a control hot SMA binder course mixture. Both of these mixtures were utilized as part of ...
