eneva < 100 > Waste GRI 306-1 | 306-2 | 306-3 | 306-4 | 306-5 | SASB IF-EU-150a.1 Our activities have no significant potential impact on the environment due to the waste generated, mainly ash from coal-fired power plants, followed by clay gravel, resulting from the drilling of natural gas wells, but of little relevance. Nevertheless, to comply with the National Solid Waste Law and standardize the activities over the entire management process, from generation to final disposal, we adopted a corporate Waste Management procedure starting in 2020. It aims to ensure the correct segregation, for temporary storage, transportation and economic and environmentally appropriate final disposal. In the year, due to the higher dispatching of the mineral coal assets, we registered a 79% increase in the ash generated by the activity, and 100% of this waste is prepared to be sold and reused by the cement industry, without environmental impacts and encouraging the circular economy, fundamental in sustainable businesses. The initiative of reuse of ash by the cement industry replaces the use of clinker in cement production and since 2016 has already indirectly contributed to a reduction of 231,000 tCO₂, through the reuse of 256,000 tons of ash. These quantities refer to the ash generation at Pecém IITPP. In 2021, we generated a total of 118,500 tons of waste, considering waste of classes I, II and III. Of this total, 81% represent our generated ash and we registered 90% in our Sustainable Destination Index (IDS). In 2021, 82,900 tons were destined for recycling, composting and/or co-processing, and another 9,200 tons were destined for industrial landfills or other purposes. The year included the introduction of the Solid Waste Management procedure in six new corporate and operational indicators in the Health, Safety and Environment Management System, which seeks to cover all the details in the management routines, locally. The management of the entire process is further qualified through a waste inventory that is prepared monthly for each unit by our Operational Environment area, as defined by internal procedures. In addition, each quarter this control is presented to the Corporate Environment area, for the consolidated analysis of the results and treatment of eventual non-compliance issues through preventive and corrective actions in all of the company's operating units. The process of segregation, classification, and packaging is our responsibility, while the final disposal is the responsibility of a contracted and duly licensed company. All of these management 82.9 thousand tons were destined for recycling 9.2 thousand tons destined for industrial landfills or other purposes procedures are compiled in a Solid Waste Generation and Disposal Inventory, per unit, containing the mapping of the waste from the generating process to the type of final disposal. We also use a Waste Transport Manifest Control (MTR) containing the classifications according to the applicable standards and legislation, duly registered in the Ministry of the Environment's SINIR system. 1 The literature shows an estimate of between 800 to 1000 kg CO₂/t Clinker (see site).
