Combined Heat and Power (CHP) System with Landfill Gas

The current solutions for the treatment of municipal solid waste are selective collection, incineration or, as a last resort, landfilling.

The disposal of waste in landfills, among many other problems, leads to the production of greenhouse gases (GHG), which are a natural by-product of the decomposition of organic matter with a composition of approximately 50% methane and 50% carbon dioxide. Methane is a potent greenhouse gas, 26-36 times more harmful than CO2 at trapping heat in the atmosphere over a period of 100 years.

Faced with this problem, instead of being released into the atmosphere, GHGs can be collected, converted, and used as a renewable energy source using power generators, which produce electricity by burning landfill biogas. This electrical energy can be used for self-consumption or injected into the electricity distribution network.

With the production of electrical and thermal energy from a fuel such as Landfill Biogas, we obtain a Cogeneration system as a source of Renewable Energy.

Recognizing the benefits of this solution, Mota-Engil ATIV specialises in the Design, Installation and Maintenance of Cogeneration Systems, and has extensive experience in the Operation and Maintenance of Cogeneration Systems from Landfill Gas, Biogas from livestock farms, such as pig and cattle farms, and Biogas generated from vegetable waste resulting from the agri-food sector.

Mota-Engil ATIV is the representative in Portugal of 2G (, one of the world leaders in Energy and Cogeneration solutions.
