The government of Mexico City was to hold one of its 'bartering' or swap markets on 19 October, wherein residents bring in recyclable trash in exchange for foodstuffs including fresh vegetables. The fairs' dates and locations were liable to change, though tending to take place every week or fortnight since 2025. The next one was scheduled for the morning hours, inside the Chapultepec park. The markets are part of the city's bid to boost trash separation and recycling habits in the population, El Sol de México reported on 16 October. Its government wants to halve the amount of trash buried under ground by 2030 as part of a Basura cero or Zero Trash agenda.
