The UN's Latin American and Caribbean Climate Week in Salvador, held in August, generated 228 kilograms of organic waste. Through a biooptimization process, the material was reused, generating 250 kilograms of fertilizer for a public school garden. The initiative was a partnership between the Salvador Municipal Secretariat of Sustainability, Innovation, and Resilience, the Coletor Cooperative, and the Viva a Vida Environmental Services organization.
"We've had this service since March 2018. Each month, it converts eight tons of organic waste from the mall's food court into fertilizer," said Luciana Fraga, the facility's environmental analyst. During biooptimization, after the waste is refrigerated, acidity is controlled, odor is reduced, and the material is shredded at the Central Waste Treatment Unit (UCTR). The material then undergoes a drying period until it's ready for use in the garden as an input.
