Those opposed to incineration projects say they plan to carry trash to Casa Presidencial Sept. 8 as part of a protest.
The organizers said that they would also separate the garbage to protest the presidential decree that will permit the burning of garbage in Costa Rica.
Generally participants in this protest believe that a recycling program can substitute for the collection and burning of garbage.
The protest is believed supported by the Partido Acción Ciudadana, which also happens to be the political party of President Luis Guillermo Solís.
The incinerators, which would be installed in municipalities that request them by private firms, are supposed to generate electricity with the heat that is created.
Those announcing the protest see the incinerators as having grave environmental impact. They said they prefer less consumption and recycling.
