SEaB Energy, one of the UK’s brightest innovators of waste to energy technology, has fully implemented its containerised power plant at a hypermarket owned by Portugal’s largest retailer.Power in a box site

This is the first time that an anaerobic digestion system, that converts inedible food waste to energy, has been installed at a supermarket site anywhere in Portugal.

The strategic partnership agreement, signed with Modelo Continente, part of the Sonae Group, was conducted through SEaB Energy’s Portuguese agent, Biowaste SA. The conclusion of the deal has resulted in SEaB Energy’s ‘Flexibuster’ technology being installed at Continente’s hypermarket in Gaia, located in the south of Porto.

The Flexibuster will convert approximately 600kg per day of inedible supermarket food waste into energy that will generate around 80,000Kwh of electricity, as well as 180 tonnes of fertilizer per annum. The electricity will be used on site whilst the fertilizer will be sold on, creating another valuable revenue stream for the supermarket. 

The total offset savings for the first year is projected to be around €27,000 which includes income from energy generation and cost savings from the elimination of waste transport and landfill costs as well as other operational expenses. 

Modelo Continente is a pioneer in the adoption of low-carbon, environmentally-friendly measures that reduces its demand for energy and includes LED-only lighting in all new stores, installation of over 112 photovoltaic power plants and the use of more efficient heating and cooling equipment.
