Improper disposal of household cooking oil is not only an ecological hazard, it’s also a missed opportunity to recycle the waste into new products. Oil poured down drains also increases water treatment costs. Members of the Rotaract Club of Penápolis in São Paulo state distributed 400 funnels to help residents collect oil in bottles, along with pamphlets explaining the benefits of recycling and how to do it. Members of a recycling cooperative in Penápolis gather the bottled oil and sell it to be turned into biodiesel, homemade soap, paints, resin, and animal feed. “It’s essential to reduce and prevent pollution in all its forms,” says club member Lucas Silveira de Campos.
