Electric furnace slag (EFS) is produced during reductive smelting (phase 3 of the production procedure) - and made up mainly of iron oxides and silicon dioxide at a content of about 35% each, the rest being oxides of calcium, magnesium, aluminum and chromium.

It is used in sand blasting and as raw material in the cement industry. We participated in the ExxonMobil Adriatic Liquified Natural Gas (LNG) Project, the major European project and pioneer in underwater ground-base structures, enhancing our liaisons and setting foundation for future practice and applications. During 2006, we made our first exports of EFS to North America in LARCO’s history, as well as creating new liaisons with Opta Minerals, Canada, and with North American companies operating in the abrasive industry. In the Greek cement industry, local sales were enforced within the sand blasting sector.

Converters slag is used as aggregate for the production of special type of concrete and for covering of oil tubes, or other similar works, in Europe, North Africa and Middle East.

The total quantity produced in 2006 was used in projects in Nigeria, USA, Italy, Canada, UAE, Norway and long term contracts were secured, underlying the new corporate strategy of looking into potential new markets.
