An arrangement for utilizing biogas or landfill gas includes a plurality of gas-collecting units (2) disposed in at least one waste-material landfill (1). The gas-collecting units are connected via conduits (3) to a common collecting station (4) which generates a subpressure in the conduits and from which collected gas is used to fuel an internal combustion engine (6), preferably an engine intended for powering an electric generator. The suction side (7) of the engine (6) is connected to the conduits (3) such as to generate in the conduits the subpressure required for said gas collection. In a method of utilizing landfill gas, the gas is collected at the gas-collecting sites (2) and transported therefrom to the collection station (4). The suction side (7) of the engine (6) is connected to the conduits (3), suitably after being started-up with conventional fuel, so as to generate in the conduits the subpressure necessary to collect the gas. |
