Electricity from landfill gas in Brazil

São João Landfill, São Paulo, Brazil Energy Industries

São João Landfill Gas-to-Energy is a project designed to explore the landfill gas produced in Aterro Sanitsário. The project is located in the metropolitan region of São Paulo, Brazil’s biggest city.

At a glance

  • The São João Landfill Gas-to-Energy project makes use of the landfill gas to explore the energy potential and thereby minimize environmental problems related to global warming.

  • This project will effectively prevent the release of greenhouse gas emissions into the atmosphere.

  • This project generates work opportunities to construction, operations and maintenance.

São João Landfill Gas to Energy Project

The landfill has generated large quantities of methane gas since its origin but most of it was lost through passive ventilation. The São João Landfill Gas-to-Energy project makes use of the landfill gas to explore the energy potential and thereby minimize environmental problems related to global warming. An estimated amount of the annual reduction of greenhouse gas emissions is around 816,940 metric tons of CO2. The energy generator generates around 20 MWh/h in daily energy. The main goal of the project is to explore the gas produced in São João landfill for electricity generation. The landfill has been designed according to modern practices. The project tries to maximize the prevention of the release of greenhouse gas emissions, whilst generating electricity. Furthermore, the project aims to provide opportunities for socio-economic benefit.

Environmental Benefits

This project will effectively prevent the release of greenhouse gas emissions into the atmosphere. The methane gas extracted from the landfill is combusted to generate electricity which is going to feed the Brazilian grid. Because methane is the main component of natural gas, it can be used to generate energy with a much lower climate impact than simply letting it seep out. With that, emission reduction occurs due to fossil-fueled energy generation displacement at the margin of the electric system.

Socio-economic benefits

This project generates work opportunities to construction, operations and maintenance. Furthermore, it provides educational opportunities through the ''Ver de Perto" program. It also promotes a model for Landfill gas-to-energy projects in Brazil that can be replicated. Furthermore, the project provides emission reduction revenues to be shared amongst the municipalities of São Paulo, thereby increasing the available cash flow for other waste management investments, such as the closing of non-approved dumping sites and improved awareness of correct waste management.

Project Verification

The Clean Development Mechanism allows emission-reduction projects in developing countries to earn certified emission reduction (CER) credits, each equivalent to one tonne of CO2. These CERs can be traded and sold, and used by industrialized countries to a meet a part of their emission reduction targets under the Kyoto Protocol. The mechanism stimulates sustainable development and emission reductions, while giving industrialized countries some flexibility in how they meet their emission reduction limitation targets.
