Scrap Iron Recycling Foundry. Solutions for Flue Gas Cleaning

Companies operating in the ferrous scrap recovery sector play a key role in the circular economy, recycling materials from demolition sites, industrial waste, and various scrap metals and converting them into new productive resources. The entire ferrous scrap melting process, however, can generate harmful emissions, including sulfur oxides (SOx), hydrochloric acid (HCl), and hydrofluoric acid (HF), as well as traces of heavy metals. These compounds, if not properly treated, pose a significant risk to the environment and human health. To mitigate the impact of these emissions, foundries employ advanced flue gas purification systems designed to trap particulates and neutralize harmful gases through a series of technologies and chemical reagents that comply with environmental regulations.

Metaltek Solutions

Metaltek provides customizable solutions that can be adapted to the needs of each company for the treatment of flue gasses emitted by the melting process for the recovery of iron scrap.

FAQ

How is the disposal of fumes produced by foundries in the ferrous scrap recovery process handled?

Foundries dedicated to recovering ferrous scrap perform essential activities for recycling iron materials from various industrial and civil sectors. During the high-temperature melting of such scrap, fumes containing harmful substances to the environment and health are generated, such as Sulfur Oxides (SOx), Hydrochloric Acid (HCl), and Hydrofluoric Acid (HF), as well as heavy metals which may be present as impurities in the recycled materials, such as paint. For this reason, modern recovery facilities use sophisticated multi-phase purification systems to treat the fumes. These systems, utilizing technologies like bag filters, chemical reactors, and scrubbers, remove harmful substances and neutralize acidic gases. The chemical reagents used vary depending on the emissions being treated, with the goal of ensuring full compliance with current environmental regulations and preserving the surrounding environment.

What kinds of pollutants are released when melting ferrous material for recycling?

In the melting of iron scrap, substances present on the scraps, such as chemical compounds from surface treatments like paint, are inevitably included. This releases Sulfur Oxides (SOx), Hydrochloric Acid (HCl), Hydrofluoric Acid (HF), and heavy metals during the melting process, which have negative effects on the environment and human health.
