Based on an analysis of environmental legislation and the adoption of internal procedures, we developed a policy aimed at reducing and properly disposing of waste and materials. This policy includes sending waste only to recyclers and avoiding landfills as much as possible; ensuring the greatest possible use of materials; implementing reverse logistics projects; work on raising awareness among suppliers and society around the work on the importance of segregating recyclable waste. Since 2020, we have implemented the control of receipt of materials in an online format in our construction sites, which guarantees control and tracking with invoice and quality seals.
For the storage of different types of waste (organic, recyclable and toxic), we follow Exhibit I of Law 16642, according to which every building to be built with an area greater than 750 m2 must be provided with compartmentalized shelter, sufficiently dimensioned, and with external access to facilitate collection. We also adopted the CDF (Certificate of Final Destination) for waste generated in construction, such as waste recycling plants, cement industry, and biomass factories.
Monthly monitoring via the PDTO Portal (Program for Technical Performance of the Construction works) and internal audits allowed expanding the capacity to manage the processes and routines of the construction sites. Continuous assessments and approvals are carried out at the construction sites for buckets, earthworks, and waste disposal suppliers. Since 2015, we have had a technical team responsible for checking compliance with all items. This team includes professionals in the areas of Quality, Sustainability, Supplies and construction engineers.
All transporters and receivers of waste generated at our sites must have the necessary environmental documentation and receive periodic visits and inspections by a professional selected by Even's Quality department.
In 2021, we implemented the Sigor System as a standard for managing the collection of recyclable and hazardous waste at all construction works and for reverse logistics to decentralize the process of removing land between construction works and ensuring autonomy with separate contracting the excavation and earthworks process.
All construction works follow an operational pattern of reverse logistics focused on the disposal of materials. We negotiate with our suppliers to unpack the delivered materials, such as wood, mortar, light bulbs, scrap steel, ceramics, cardboard and plastic. All burned-out bulbs are counted before disposal and sent to the warehouse for collection by the supplier.
Concrete block residues are separated and sent to specific buckets for removal by the manufacturer, as well as all steel scraps, or any useless metallic material (empty and dry paint cans, clean aluminum, clean metal, clean stainless steel, wire of copper and metallic profile) are collected by the suppliers.
Hazardous waste, including machinery that uses diesel oil, is disposed of in boxes with sawdust and/or sand so that they do not touch the ground. The stall where these materials are kept has restricted access and is located in an isolated, identified and ventilated place, with adequate disposal, following current procedures and regulations.
One of the main challenges is the reduction of the "mix" rubbish (which does not go through sorting and ends up in landfills). In 2019, over 97.25% of waste was diverted from the landfill (0.91 Kg/m2); in 2020, 98.85% of waste did not go to the landfill (0.31 Kg/m2); and, in 2021, 97.57% of our waste was diverted (1.08 kg/m2). Our goal is to reach 95% utilization, with an average generation of less than 5.00 kg/m2.
The evaluation and approval of suppliers and destinations are key in the management process. The hiring of suppliers to remove buckets, big bags, or earth goes through several steps and a rigorous analysis of the environmental documentation of the transporter and the receiver by the Quality area, besides a site visit. In 2021, we approved three new waste destinations.

Since 2019, one of the main practices in waste treatment has been the transfer of soil between construction works. This ensures reuse and reduces the environmental impact. The strategy enabled the internal reuse of land in the backfill and landscaping processes — in these two areas alone, six thousand tons of land were reused in the last three years.
With this program in 2019, we avoided the emission of 7,627 tons of CO2e if this land were sent to landfills. For the control and management of transfers of soil and buckets, we follow the Municipal Urban Cleaning Authority (AMLURB), the body that supervises and guides the disposal of civil construction waste.

The increase in waste is directly linked to the greater number of works in the finishing phase. This is why there is an oscillation between one year and another. The same applies to hazardous waste, the highest concentration linked to works in the delivery phase. Currently, we have goals to reduce the waste mix, but we aim to study better methods to reduce the amount of waste, regardless of type/class. We monitor the generation via PGRCC of the works and understand each particularity.
