White Black Slag Technology SRL

Founders, Backgrounds, and Bench

No founding team, executive leadership, or operational staff have been disclosed in public registries or press. The company's status as an innovative startup in Italy is confirmed, but the absence of a visible team is not surfaced in the public research.

Data Accuracy: YELLOW -- Company registry and patent data are public, but key operational details are not independently verified.

Company Overview

White Black Slag Technology SRL is a Treviso-based Italian company focused on a narrow but significant industrial waste problem. The company's public footprint is anchored by a 2016 international patent for recycling white slag, a by-product of steel deoxidation [Google Patents, 2016]. It is registered as an innovative startup in Italy, with an active VAT number (P.IVA 04988140267) and a reported paid-in share capital of EUR 1.5 million, authorized up to EUR 20 million [WBST Italia, 2024] [reportaziende.it].

Beyond the patent filing, the company's website describes its mission as implementing "innovative, patented solutions aimed at regenerating ladle furnace slags (steel refining) and providing controlled atmosphere cooling for the cap lids of EAF furnaces (steel melting)" [WBST Italia]. The most recent verifiable corporate action is a June 2024 notice extending the deadline for a capital increase to June 30, 2025 [WBST Italia, 2024].

Data Accuracy: YELLOW -- Company registry and patent data are public, but key operational details are not independently verified.

The Product and the Stack

White Black Slag Technology SRL's public offering centers on a single, hardware-focused solution for a specific industrial waste stream. The company's technology is designed to process white slag, a by-product of steel deoxidation, in various physical states from solid to liquid for reuse [Google Patents, 2016]. According to the company's website, this patented approach aims to regenerate ladle furnace slags used in steel refining and provide controlled atmosphere cooling for the cap lids of Electric Arc Furnaces (EAF) [WBST Italia].

Data Accuracy: ORANGE -- Core product claims are based on a single patent filing and the company's own website description. No independent verification of technological efficacy or commercial deployment exists.

The Market They Are Entering

The market for steel slag valorization is a niche within industrial waste management. For every ton of steel manufactured, the process generates between 150 and 200 kilograms of slag by-product [Wikipedia].

Metric	Value
Steel Slag By-product	175 kg per ton of steel (midpoint)

Data Accuracy: YELLOW -- Market size (waste volume) is a widely cited industry figure. Regulatory and demand drivers are inferred from public policy frameworks, not company-specific traction.

The Competitive Field

White Black Slag Technology SRL operates in a niche defined by a specific industrial by-product. The company's positioning rests on a patented method for recycling white slag, a material generated at a rate of 150-200 kg per ton of steel [Wikipedia]. WBST's claimed defensible edge is its intellectual property, specifically the 2016 international patent (WO2016116884A1) covering the treatment of slag in various physical states [Google Patents, 2016].

Data Accuracy: YELLOW -- Competitive analysis is inferred from the patent and industry context; no direct competitors were identified in public sources.

Opportunity

The prize for a successful steel slag recycling technology is a permanent position in the global steel industry's decarbonization supply chain. The company's 2016 international patent outlines a method for recycling white slag in various states [Google Patents, 2016].

Scenario	What happens	Catalyst	Why it's plausible
Technology Licensing to Major Mills	WBST licenses its patented process to top European steel producers for integration into existing furnace operations.	A successful pilot deployment at a single, named mill.	The steel industry has a long history of adopting licensed process technologies.
Acquisition by Plant Engineering Firm	A large engineering and construction firm acquires WBST to integrate the slag recycling tech into its suite of green steel solutions.	The European Union's Carbon Border Adjustment Mechanism (CBAM) creates urgent demand.	Consolidation in the cleantech space is common.

Data Accuracy: YELLOW -- The core market size figure (slag per ton of steel) is widely cited. The company's patent and stated activities are confirmed, but growth scenarios and comps are extrapolated from industry dynamics.
