The GasBox is designed to generate electricity and heat from low-grade methane emitted at older landfill sites and waste water treatment plants.

Under the contract with Ulricehamns Energi (UEAB), Cleanergy will provide two GasBoxes for a landfill site at Övreskog, which serves 23,000 residents of Ulrichehamn city in Sweden.

In Norway, Cleanergy will supply five GasBoxes to GLT-Avfall, a waste management company co-owned by five municipalities, for its largest landfill.

GasBox is installed inside a modular container which comprises a power management system with remote access, a fuel pipe and a heat and electricity connection to a house / factory / warehouse with optional grid functionality.

Cleanergy chief commercial officer Alexander Vestin said: "Since we launched the GasBox last June, the response from the waste management industry has been phenomenal because, quite simply, it is the only system which can generate electricity and heat from the dirty biogas with low methane levels generated at closed landfill sites."

The company has so far delivered the GasBox in Germany, Norway, Poland, Slovenia, Sweden and the UK.

Cleanergy develops, manufactures and installs energy solutions for the solar and gas industries.
