Environment

We use equipment with baghouse filters in order to contain the emission of particulate matter during furnace operations, product crushing and charcoal unloading, thus avoiding environmental impacts. LIASA also maintains two Air Quality Monitoring Stations at strategic locations in the city of Pirapora, Minas Gerais, which provide real-time data on air quality in the city.

We invest in recirculation and reuse of water and industrial wastewater. By doing this, we avoid discharging wastewater into rivers, streams and lakes. We also maintain the Water Resources Consumption Reduction Program (PRCRH), aimed at promoting the efficient use of water in the company, which reduces waste and highlights the improvements implemented over the years.

Through the Solid Waste Management Program (PGRS), we seek to reduce the generation of waste from its source, carrying out proper segregation, minimizing environmental risks and ensuring correct handling and final disposal. We also invest in raising employee awareness through training and hands-on initiatives, such as Waste Sorting, in which we sort and donate waste to the Waste Pickers' Associations in Pirapora, contributing to local social and economic development. In addition, we sell various types of waste that can be reused or used to make other products or by-products.

In an effort to improve energy efficiency and help to reduce consumption, we run the Energy Consumption Reduction Program (PRCE). This program makes it possible to invest social and environmental values in the daily life of the company, enabling changes in employee behavior and allowing us to become a leader in good environmental practices, with a focus on conscious power consumption and, consequently, the conservation of natural resources.

LIASA adopts responsible forest management practices and preserves protected areas in the Cerrado and the Atlantic Forest, in accordance with the actions described in the Environmental Impact Studies (EIA) and Environmental Control Plans (PCA). These actions are designed to prevent environmental impacts resulting from forestry, bioreducer production and mining activities, which have been proven to be effective by the results of monitoring of fauna, flora, water resources and effluents.

As well as preserving the environment, we are committed to the development of our local community and strive to achieve that goal. To meet this objective, we created the Environmental Education Program (PEA), which raises awareness among our employees and the surrounding communities about the importance of genuinely caring for the environment in which we live.

We adopt the strictest standards for CO² emissions. As pioneers in the production of green silicon, which captures more carbon dioxide (CO²) than it emits, we are the first company in the industry to report our inventory in the Brazilian GHG Protocol Program, earning the Gold Seal in 2023. Emissions control is a fundamental pillar in our ESG strategy, with specific commitments, objectives, targets and KPIs.

Through our stake in three solar energy complexes, we are getting closer to self-sufficiency, with almost 100% of our electricity coming from solar sources. This strengthens our "zero carbon" strategy. Furthermore, by using solar energy to produce silicon, we close an important cycle for this mineral, which is considered a raw material for making photovoltaic panels.
