Circular Economy

O Grupo CSN applies the concept of the circular economy across all sectors and businesses in which it operates. Focused on generating value from the maximum utilization of natural resources, the company evaluates solutions and implements technologies for the reuse of materials in its own production processes or their utilization in other production chains. With an integrated and vertically integrated steel production process, CSN generates different types of by-products that, instead of being sent to landfills, are commercialized and reintegrated into various industries – including fine chemicals, pharmaceuticals, and agribusiness, among others. Integrating environmental responsibility with the pursuit of value generation across all its businesses, CSN has created the Special Sales area, which ensures proper disposal for each type of by-product, with sales both domestically and internationally. The commercial unit is divided into six different segments:

• Carbochemicals: Generation of chemicals such as ammonia, tar, BTX, and sulfur;
• By-products and waste: Slag, zinc and galvalume dross, oxides, and other by-products generated;
• Surplus and unserviceable items: Sale of unused materials, paper scrap, motors, pumps, other scrap without internal application, and obsolete warehouse materials;
• Assets: Sale of divested assets – trucks, cars, and equipment;
• Opportunistic steel: Sale via auction of opportunistic items such as coils, rolls, sheets, and tubes;
• Business development: Fostering new value opportunities for by-products throughout the CSN Group and partnerships with universities and companies.

Through the special sales area, we manage and create value for by-products, contributing to cash generation and the development of the circular economy, which provides operational eco-efficiency, integrates our business segments, and contributes to sustainable development. We use materials from our own operations for the production of consumer goods.
