Paper Title
REUSING SLAG FOR SOIL IMPROVEMENT AND SUSTAINABLE DEVELOPMENT

Abstract
Slag is a waste by-product of the steel industry. It is produced when metal is melted or produced by thermal processes. One of the biggest challenges in today’s steel industry is the generation of large quantities of waste. The European Union’s (EU) program (HORIZON 2020) aims to promote an eco-friendly economy, and one of its key objectives is to recover and recycle waste from the metalworking industry (with the aim of achieving “zero waste”). Increasing the use of slag in various applications is an essential step towards a sustainable development, resulting in the preservation of natural resources. Soil pH is an important parameter because it affects the mobility of heavy metal ions. An acidic soil pH results in the dissolution of minerals and the adsorption of hydrated oxides of heavy metal ions (Fe, Mn and Al). The aim of the present study is to investigate how the possibility of reusing waste slag that is dumped in landfill can contribute to the remediation of soil acidity.
