Sigma Lithium Corp (TSX-V:SGML, NASDAQ:SGML) said its CEO and co-chairperson Ana Cabral-Gardner attended a commemorative ceremony for World Environment Day with Brazil’s President Luiz Inacio Lula da Silva and the country’s Environment and Climate Change Minister Marina Silva on Monday.
The company said Cabral-Gardner joined other business leaders, distinguished environmentalists and representatives of civil society, congressmen, and senior members of the federal government at the presidential Palácio do Planalto in the capital Brasília for a high-level discussion on the most pressing environmental topics affecting Brazil.
Other Sigma Lithium executives including institutional relations director Ligia Pinto, chief marketing officer Marina Bernardini and co-chair of the technical committee Vicente Lobo also attended the commemorative ceremony, it added.
"Sigma Lithium's contribution to environmental sustainability has been widely recognized as placing Brazil on a unique trajectory in the lithium industry: Sigma Lithium is the only ‘Zero Tailings’ global producer,” Cabral-Gardner commented.
“That, added to our efficient water usage, low carbon and zero chemicals, drive the competitive advantage of the company as a supplier of ‘green lithium’ and ‘green tailings’, as we contribute to enabling the ‘green battery’ to support electric vehicles.”
The company noted that it began producing high purity 5.5% battery-grade sustainable lithium (green lithium) in April of this year, in a process that uses 100% renewable energy and recycled water at its Greentech lithium processing plant.
More recently, it announced a pioneering deal to move towards "Zero Tailings" by selling its high-purity, zero chemicals, approximately 1.3% lithium oxide, ultra-fine tailings generated by the Greentech Plant.
The first shipment of 15,000 tonnes of Green Lithium and 15,000 tonnes of Green Tailings is expected in June 2023.
