State of Rio generates 4.5 million liters of leachate per day, study shows

oglobo8 September 2026 at 10:00

A study by the Master's program in Environmental Sciences at the University Veiga de Almeida (UVA), based on data from the National Basic Sanitation Information System (SINISA), revealed that the State of Rio de Janeiro generates 4.5 million liters of leachate per day.

Leachate is a highly polluting liquid generated from the decomposition of solid waste in landfills, representing one of the main environmental challenges related to waste management in the state.

The research draws attention to the dimension of the leachate management problem in Rio de Janeiro, highlighting the need for adequate solutions for the treatment of this effluent that is dangerous to the environment and public health.

Fire may have ignited human language: the bonfires that drove the origin of speech

New research suggests that bonfires may have been fundamental to the development of human language. Researchers discovered that the rhythm of flames produces frequencies similar to brain rhythms and human speech, which would have facilitated social synchronization during nighttime conversations. Fire also would have encouraged the transition from gestural to oral communication, by making distant gestures difficult but offering a shared visual stimulus that invited storytelling. This theory indicates that bonfires were not only sources of heat and light, but social catalysts that shaped the evolution of language.
