Projects

With a global investment of around 3.6 million euros, the project of Dourogás Renovável and Águas do Tejo Atlântico aims to produce biomethane from the sewage produced at Firelas’ wastewater treatment plant, in the municipality of Loures. The installed purification unit is VPSA (vacuum pressure swing adsorption). The biomethane produced will be injected into the natural gas grid and used to power vehicles, enhancing sustainable mobility. This project also aims to produce synthetic methane through a methanation process, in which the hydrogen used originates from solar-powered water electrolysis

The Move2LowC is a project with a consortium composed of several co-promoters and partners, which arises due to the exponential growth of the mobility sector and the consequent increase of GHG emissions caused by it. The primary purpose of the project is to decarbonize transportation by producing sustainable biofuels and developing innovative technologies. Dourogás Renovável is present in one of the Move2LowC subprojects, PPS4, where the goal will be to convert carbon dioxide from biogas into biomethane by an improved method. The final product obtained will then be compressed or liquefied for use in mobility. This project include the production of methanation catalysts and the development of a more efficient methanation reactor.

This biomethane production unit is located in the Urjais landfill in the district of Bragança and Mirandela municipality. It consists of a vacuum pressure swing adsorption (VPSA) system, which allows the purification of biogas produced from the urban solid waste from Resíduos do Nordeste. The biomethane produced by the unit is then used for mobility, in the supply of waste trucks from the Resíduos do Nordeste, and for injection into the gas network. To this end, the unit has equipment that controls the quality of the biomethane produced to ensure that its composition is identical to that of natural gas. This project was the first biogas purification unit installed in Portugal.
