Just-in-time delivery

A key asset is the company’s extensive silo network. This gives us the capability to store up to 20,000 tonnes of filler, across 60 strategically placed silos. As a result, we can distribute throughout the whole UK on a just in time basis. We can also bag asphalt filler for export outside the UK.

LKAB Minerals also has storage silos located on customer sites to collect excess material from the asphalt manufacturing process, which can then be recycled.
