Abstract

Scania CV AB invests SEK >1.5 billion in a green field foundry. E-mobility and electrification of heavy trucks is in the origin and the development is moving fast. However, the combustion engine, running on biofuel, will play an important role in the shift to a sustainable transport system. Therefore, producing high quality castings for combustion engines will be crucial over the next decade.

The energy intensity in a foundry is higher than in any of Scania's manufacturing processes. A foundry consists of a complex composition of sub-processes with several energy intensive steps of heating, cooling and forming. The foundry is expected to start the ramp up procedure during late 2020 and produce at full capacity in the end of 2023.

The project has set up ambitious targets regarding sustainability. The new foundry should:

– Operate on 100 % renewable energy

– Install 100% heat recovery capacity compared to heat demand

– Increase the energy efficiency by 50% per produced castings, compared to existing foundry (Base line 2016)

– Pollute 0 % CO2 emissions

To realise this targets and untapped potential, a new working process have been developed to integrate energy efficiency in the ordinary investment and engineering process. This extended abstract introduces the reader to an overview of an novel method to realise energy saving and decarbonisation potential in green field manufacturing processes. The audience will get inspiring and practical examples from each working step in the project, from pre-study – purchasing machines – to verifying the results of integrating energy requirements in the working process.
