LCA proves higher eco-efficiency of new semitrailer truck alternative

Customer / partner: Outokumpu Oyj

Challenge: To enhance eco-efficiency of semitrailer trucks during their whole life cycle.

Solution: VTT and Outokumpu conducted a life cycle carbon footprint study of semitrailer truck with stainless steel tank to find out the most eco-efficient solution. Two different tank materials were compared, taking into account raw material manufacturing, manufacturing of the tank, use of fuel, and total emissions.

Key benefits:

• LCA study showed which alternative is the most eco-efficient:
  
  • After 5000 km (or 125000 tkm) lighter tank was demonstrated to have higher eco-efficiency due to larger payload
    
  • The use of alternative tank leads to 8% lower carbon footprint and significant savings in fuel costs during truck’s life cycle
