Orizon Sustainability and ESG Initiatives

ORIZON ABOUT US NATURAL CAPITAL GOVERNANCE HUMAN CAPITAL SOCIAL PLATFORM PERFORMANCE GRI SUMMARY < 21 > BLENDING AND FUEL DERIVED FROM WASTE In waste, Orizon sees a potential for generating an alternative fuel and providing sustainable solutions. As such, it also makes use of the waste arising from the manufacturing processes of large-scale industries. To meet this demand, the company has co-processing plants, where Refuse Derived Fuel (RDF) or Hazardous Waste Derived Fuel (HWDF) is generated by means of a blending process. In this process, the waste generated and discarded by industries, such as resins, glues, latex, tires, rubber, plastics, paints and solvents, is crushed and mixed to form a solid or liquid blend. The result is a mix with high calorific value that can be used as an alternative fuel for cement production furnaces. With the two blending plants, located in Magé (RJ) and Sorocaba (SP), Orizon has a 150,000 ton capacity. The operation follows the concept of a circular economy and contributes to sustainability since it substitutes the fossil fuels used by companies in the manufacture of cement and reduces the volume sent to landfills. The waste received for co-processing is approved by the National Environment Board (Conama) and other relevant legislation, and should fall within the standards established by cement factories. The materials are classified as Class I (hazardous) and Class II (non-hazardous) waste, and need to adhere to a number of blending requirements in terms of concentration of chlorine, pH and calorific value. To achieve this, Orizon has a team of specialists who perform diagnoses on the waste, evaluating the legislation, characteristics and logistics to guarantee the safety and viability of the service. In addition to this, all the necessary requirements for the blending activity are fulfilled, including the obtaining of the Fire Department Inspection Certificate (AVCB), licenses from the Federal Police and Army, and ISO 9001-2015 and ISO 14001-2015 certifications. THE OPERATION FOLLOWS THE CONCEPT OF A CIRCULAR ECONOMY, CONTRIBUTING TO SUSTAINABILITY BY SUBSTITUTING FOSSIL FUELS Blending capacity 150,000 TONS
