WHAT IS LIFE CYCLE ENERGY ANALYSIS?

This a way of analysing the way energy is used in the manufacture of a product and throughout it’s useful lifetime.

It involves analysing the energy required to extract raw materials from the ground, transportation of the materials to the processing plant, processing raw materials into usable materials, manufacturing a product, the energy consumption throughout the product’s useful life and eventually energy required for recycling and disposal.

 

 

SAVING ENERGY AT EACH STAGE

EXTRACTION OF RAW MATERIALS
Place processing plant close to source of raw materials


PROCESSING RAW
Use as much recycled materials as possible


MATERIALS TRANSPORT TO FACTORY
Build factory close to materials processing plant and use trains not individual lorries for transport


STAGES OF MANUFACTURE
Use green energy and save as much energy as possible


DISTRIBUTION OF PRODUCT
Use hybrid or electric vehicles


END OF LIFE RECYCLING
Design product to be easily dismantled, no need for special / power tools

 

 
 
 

 

CASE STUDY - VOLVO CARS

Volvo use trains to transport raw and processed materials not lorries.

Volvo uses green energy such as electricity produced through wind power and hydroelectricity.

Volvo claim that 85% of the materials they use can be recycled and used again.

Volvo have reduced their CO2 emissions through the use of green energy and recycling materials.
