    New AD Plant

    PRESS RELEASE
    September 2012

    Xergi gets its third order from the same client
    After taking stock of the market, Staples Vegetables has now placed their third order with Xergi in three years
    Staples Vegetables, one of the UK’s largest vegetable growers with several production units around the UK, has decided to set up another biogas plant in Sibsey near Boston.
    The national grid has insufficient capacity near Sibsey to be able to supply the power required for the company’s increased production of vegetables, including refrigeration and storage of potatoes. This is why Staples has asked Xergi to build a biogas plant that will be able to produce the required capacity of electricity as well as convert the company’s out of specification vegetables to a good-quality fertiliser.
    This means that Staples Vegetables has placed its third order with Xergi in just three years.

    Living up to expectations
    The owners of Staples Vegetables, brothers George and Vernon Read, examined the market thoroughly before they decided who was to build their new biogas plant.
    “We have looked at various options and evaluated each on the basis of a number of factors such as long-term costs, profits and quality. We have also looked at various potential suppliers. How stable are the businesses? Do they have solid financial backing? It has been important to us to choose a company that is able to guarantee its product and solve any problems that may arise during construction,” explains Vernon Read.
    After having assessed a number of suppliers, Xergi was chosen once again.
    “They meet all the criteria that are important to us. From our point of view, their plants represent a good investment. Xergi, of course, also has the advantage of already having built a plant that we are very happy with,” says Vernon Read.

    Great flexibility
    As far as Xergi’s technology goes, Staples greatly values the flexibility of the plant.
    “We are able to use different types of biomass, as well as pasteurise if required. “We are very pleased with the feeding system,” explains Vernon Read. “By being divided into three parts it offers us the flexibility to continue operation should any problems arise,” he said.

    The new plant
    The new biogas plant in Sibsey will be built to operate on out of specification vegetable and maize silage.
    Two engines with a total capacity of up to 2 MW of electricity will also be installed. The plant will first and foremost supply electricity to cover what is required by the vegetable production on site. Surplus power will be exported to the national grid.
    At the same time, Staples is working on plans to set up greenhouses where surplus heat from the electricity production can be used. The biogas plant will replace a diesel-powered generator which will only be used as an emergency back-up system.
    Early 2011, Staples Vegetables opened its first biogas plant located near Wrangle about 10 miles from Sibsey. In February 2012, Staples Vegetables placed their second order with Xergi. This order included an extension of the Wrangle plant where capacity will double. The extended Wrangle plant is expected to be commissioned in October 2012.
    The new plant near Sibsey is expected to be commissioned in the spring/summer of 2013.

    PRESS RELEASE

    Xergi signs large biogas contracts in the United Kingdom
    UK-based company Tamar Energy has ambitious plans to build a network of more than 40 new biogas plants by 2018. Xergi has signed agreements to supply two of its first biogas plants.
    Xergi has signed contracts to supply two Anaerobic Digestion (AD) plants to the British company Tamar Energy. These plants are among the first projects in Tamar Energy’s overall plan for a network of more than 40 biogas plants across the UK, with a total capacity of 100 MW and producing enough energy to power more than 200,000 homes.
    Tamar Energy was set up in February 2012 with a capital base of almost GBP 100 million – with an unparalleled focus on generating green energy using AD.
    Investment has come from a number of influential shareholders, including The Duchy of Cornwall, the Rothschild family and RIT Capital Partners, Dubai-based investment company Fajr Capital, the Tamar Energy Executive Management Team and Sainsbury’s, who is also a strategic operating partner.
    Its project in Retford, Nottinghamshire is to use Xergi’s NiX® technology. This patented technology makes it possible to digest large quantities of poultry manure in a biogas plant.
    Poultry manure contains high levels of nitrogen. This impedes the biological process in the digester which means that standard biogas plants are not capable of processing large quantities of poultry manure. However, Xergi’s NiX® technology removes some of the nitrogen before the poultry manure is added to the digester.
    In addition to poultry manure, the Retford AD plant will also be processing vegetable waste and maize silage. The plant will have the capacity to generate 3 MW of electricity and is expected to be commissioned in January 2014.
    The other project in Holbeach in Lincolnshire is located close to one of the region’s largest potato producers and processors. This plant will process vegetable waste and maize silage and will have the capacity to produce 1.5 MW of electricity. The plant is scheduled to be commissioned in December 2013.
