Today is the International Day for the Preservation of the Ozone Layer.
The date marks the signing of the Montreal Protocol in 1987, which established the phase-out of ozone-depleting substances. The agreement worked for a reason that applies to any environmental agenda: clear rules, set deadlines, and monitoring of results. Good intentions were not enough. It took structure and verification.
Waste management works the same way. That is why Ambipar operates at both ends of the journey.
Cidades Circulares (Circular Cities) is the urban circular economy methodology implemented with municipalities to restructure solid waste management. It reduces landfill disposal by keeping post-consumer materials in the production cycle and strengthens recycling cooperatives, a decisive link for sorting quality and for how much material actually returns to the production chain.
Retorna Machine is a reverse vending machine that accepts post-consumer recyclable packaging and issues Tricoins for each return, points that can be redeemed for discounts and benefits.
Cidades Circulares builds the structure on the ground. Retorna Machine brings the return point into people’s daily routines.
