【SMM Steel】Salzgitter's subsidiary validates new metal recovery process for steel slag

Published: Apr 1, 2026 16:21
【SMM Steel】Salzgitter's SZMF launched Project KLASSE to recover strategic metals like vanadium and manganese from steel slag. Combining "cold" processing with direct reduction, the process uses far less energy than conventional methods. Remaining mineral fractions will be used for high-quality construction. The three-year project aims to cut import dependence and turn slag into a sustainable resource.

【SMM Steel】Poland's Cognor raises rebar prices 20% since early 2026
【SMM Steel】Polish steel group Cognor Holding raised rebar prices nearly 20% effective early 2026 amid a gradual market recovery and EU regulatory changes. The company expects steps to partially offset 2025 losses and improve financial results in coming quarters. A collapse in rebar prices due to Chinese dumping and weak European demand led to revenue falling >9% y/y to PLN2.08bn. Cognor expects operating metrics to improve in Q1 2026 and a return to profitability in Q2. EU regulatory changes, including CBAM and new market protection tools, could reduce external steel supply by ~50%, supporting capacity utilization and price stabilization.

【SMM Steel】Zaporizhcoke output down 3.2% m/m in April
【SMM Steel】Ukraine's Zaporizhcoke reduced output by 3.2% m/m to 75,000t in April 2026, but up 4.1% y/y. Jan-Apr output reached 281,700t, flat y/y. Weak results early in the year were due to reduced coal concentrate supplies from shelling of port/transport infra and power outages disrupting stable ops. Output began recovering in February and continued in March-April. In 2025, output rose 2.7% y/y to 898,300t. Since 2022, the company has spent over UAH360m on coke oven battery overhauls. Zaporizhcoke is part of Metinvest Group, with Zaporizhstal as its main consumer.

【SMM Steel】Wuppermann Metalltechnik opened a new tube plant at its Altmünster, Austria site. Construction began in July 2023, with an estimated cost of €40m. The new line enables a wider size range: complex geometries up to 130mm cross-section and 1-4mm thickness, with pickled, galvanized, or Zn-Mg coatings. For climate-neutral heating, geothermal probes totaling ~5,000m were installed. The first pipe was made in July 2025. Austria's steel output rose 5.9% y/y to 620,000t in 2025, ranking 20th globally.
