Biogas production from municipal waste in Rio de Janeiro

either the solution and the problem

  • Anaide Ferranco Leiden University


With the current consensus about the need to decarbonise the energy system to decrease its GHG emissions in order to mitigate global warming, biogas has been growing worldwide as a low carbon energy alternative. Biogas originates from the biological breakdown of organic materials. This process happens in landll sites when organic waste decomposes and produces what is known as landll gas. In compliance with the Brazilian National Policy on Solid Waste, in 2012 Jardim Gramacho landll, was closed, leaving a poll of 1,700 scavengers without their livelihood. De dump was not only important for those workers but also for approximately 12,000 inhabitants depending directly or indirectly from the waste picking activities. After de closure, a biogas plant was built on the site to collect and process methane originated in the old dump. This enterprise presented environmental improvements to the region. However, the residents who worked on the selection of recycling materials were left without a source of income. Up to now not enough public policies were implemented to ensure livelihood improvements to the waste pickers and inhabitants of Jardim Gramacho district.
