- •
Statistical dynamic material flow models have been developed and applied for the steel eco-cycle.
- •
This statistical method eliminates the need for adjustable model parameters.
- •
The lifetime of steel was shown to be between 28 and 35 years in 2012.
- •
The redundant time of steel in society was calculated to be between 4 and 11 years.
- •
The results indicates the lifetime of steel values are largely influenced by socioeconomic factors.
