Santiago treatment plant in Chile
Country of activity
Santiago du Chili
The La Farfana water treatment plant is one of Suez’s concrete responses to the challenge of climate change. La Farfana, the world’s first biofactory, has even higher ambitions: it is poised to meet its objective of zero waste, zero environmental impact, and zero consumption of fossil fuels. The plant recovers 100% of wastewater, converting it into new resources such as biogas for producing electricity and heat, and turning sludge into fertilizer for the region's farmers. 100% of the biogas produced from the sewage sludge is reused. In 2018, La Farfana received the “Momentum for Change” award. The biofactory concept is applied to all of Greater Santiago’s treatment plants: La Farfana, Mapocho, and El Trebal. La Farfana is the biggest plant in terms of capacity. By recovering sludge, the three plants produce 49 million kWh of electricity, the annual consumption of 50,000 inhabitants, plus 177 kWh of natural gas, the annual consumption of 22,500 inhabitants.
