Salvador moves to divert discarded palm oil from its streets and beaches into an energy feedstock, aiming to transform up to 6 million liters a year. The municipal scheme pairs City Hall with state-run oil giant Petrobras and vendors of the city’s signature street food to capture and reuse wasted 'azeite de dendê'.
The initiative responds to a visible problem along the coast, where waters are often streaked with a reddish-orange sheen that drifts around beachgoers, kayakers and turtles. Local vendors historically dumped used frying oil to lighten their carts, a practice that clogged sewage systems and contributed to beach pollution.
More than 3,500 women sell acarajé across Salvador, and City Hall has focused on recruiting them as suppliers. Officials are offering incentives and licenses to encourage hundreds of Baianas to join the programme, and the city will pay 3 Brazilian reais ($60 cents) for every liter of palm oil they turn in. Cooperatives involved in the collection sometimes return soap made from recycled oil to participating vendors.
Palms and their oil are woven into Bahia’s culinary history. Known as 'azeite de dendê', palm oil arrived with enslaved Africans in the 1530s and remains central to dishes such as acarajé, moqueca and vatapá. The recycling drive links that longstanding food culture to a waste-management and energy objective by channeling used cooking oil toward industrial reuse.
Organisers say the project could scale if vendors supply significant volumes, and the partnership with Petrobras gives the scheme an industrial anchor. For now the city is concentrating on formalising small businesses, reducing pollution and establishing collection routes that could feed a larger waste-to-energy operation.
