Energy Consumption and Carbon Footprintof Secondary Aluminum Cast HouseWENJING WEI Email: wenjingw@kth.se TTMVMSupervised by Docent Weihong YangOBJECTIVES
  • Background:
  • Aluminum is the second largest metal market
  • Highly recycled material
  • Problem:
  • What’s carbon footprint of secondary aluminum product
  • How to improve energy efficiency and decrease greenhouse gas
  • Objectives:
  • Energy and CO2 per ton of aluminum production,
  • Solution to increase energy efficiency and decrease carbon footprint
  • Developing a software to make energy efficiency indicators
  • RESULTS&DISCUSSION
  • Higher energy efficiency
  • Decrease heat loss ( logistic, insulation etc.)
  • Waste heat recovery( utilize exhaust gas, cooling water heat for pre-heating loads)
  • RESULTS&DISCUSSION
  • Lower environmental impact:
  • Charge more aluminum scrap instead of primary ingot
  • Applying nuclear power generated electricity ( much lower carbon footprint compare to fuel)
