The energy required to produce materials: constraints on,

13/03/2013· The energy intensity (or embodied energy) is defined as the energy required to produce a material from its raw form, per unit mass of material produced. The energy is usually measured as the lower heating value of the primary fuels used plus any other primary energy contributions. These energy requirements are dominated by two main steps: (i) harvesting and (ii) refining. For metals from,Aluminium production & environmental impact,• The amount of energy needed to make aluminium is 211 GJ per tonne, compared with 22.7 GJ per tonne for steel. 3 • The extent of the energy use owes to the strength of the chemical bond between aluminium and oxygen is significantly stronger than the same bond between iron and oxygen. As a result, much more energy is required to split the bond and form the metal. 5 Semi-fabrication and,The energy required to produce materials: constraints on,,The energy required to produce materials:, paper, plastics and aluminium.

Aluminium production process

The process where the aluminium is shaped to its required form. This process is used for making the vast majority of aluminium products from spectacle frames, telephone bodies, aeroplane fuselages or spaceship bodies. The malleability of aluminium means it can be easily rolled into thin sheets. To that end, aluminium alloys are cast into rectangular beams up to 9 metres in length, these are,Benchmarking Guides - NRCan,Energy Performance Indicator Report: Fluid Milk Plants.
