Agrivert officially opens fifth food waste recycling facility

Today Councillor Richard Thake, Chairman of Hertfordshire County Council, joined us to officially open our fifth AD facility.

Agrivert North London AD Facility located at London Colney, just off the M25, is the latest plant to join our now 5 strong AD family and adds a further 50,000tonnes of food waste recycling capacity to our network.

Councillor Thake and some 50 local dignitaries joined us at the launch which included a tour of the £14million plant. 

Designed and constructed by the Agrivert team, the new North London AD Facility was built in just 11 months and is already operating at full power converting waste into renewable energy and nutrient rich biofertiliser.

The facility was built to service Hertfordshire’s municipal food waste and local businesses although it also currently serves Essex County Council under a short term contract. Located 18 miles from central London’s Marble Arch and the same distance from Park Royal, one of the UK's largest food manufacturing hubs, we also expect to attract some waste from the wider London area.

The plant is set to process 50,000 tonnes of food and liquid wastes per year, generating 3MW of electricity which is enough to renewable energy to power around 5,900 homes. The energy produced is generally used at its closest point of need; therefore this facility is likely to directly power the local homes and businesses from which the food waste originated. 

In addition to renewable power, our valuable bio-fertiliser; known as Digestate, will help to displace fossil fuel derived fertilisers on over 3,000 acres of local farm land.  In fact, the net impact of CH4 removal, energy production and replacement of fossil fuel fertilisers means that this AD facility has the equivalent net green benefit of taking 86,000 cars off the road annually. 

Speaking at the opening ceremony, Richard Thake, Chairman of Hertfordshire County Council, said: “I welcome Agrivert’s investment in Hertfordshire and I’m very pleased to have officially opened the new Anaerobic Digestion plant at London Colney. This facility will bring a number of benefits to the county. This facility is expected to process around 50,000 tonnes of organic waste per year and will generate electricity that will be exported to the National Grid. By sorting food waste from general household rubbish we can prevent, large amount of waste being sent to landfill, where it would generate greenhouse gas emissions.”

Agrivert chief executive Alexander Maddan, commented:We are proud of this AD project and the increased accessibility to our industry-leading food waste recycling services it brings.  The new plant will offer much needed reliable capacity to local markets and we are pleased that large volumes of waste are already coming in from local sources. Local plants such as this reduce the cost of waste collection and treatment and should provide an incentive for many businesses to recycle food waste.  We are delighted to be working with Hertfordshire, Essex and London Councils, who have been supportive partners at every step. Indeed we could not have delivered this facility so quickly if we had not had such progressive relationships.


Agrivert holds a 15 year contract for the recycling of domestic food and garden waste collected in Hertfordshire and is working closely with the County to increase source segregated Food Waste collections whilst supporting districts that cannot yet achieve this by recycling comingled food and green waste at the existing In-Vessel Composting facility (IVC) located at South Mimms.

All food waste separately collected from householders within Hertfordshire District Councils, namely Dacorum, Broxbourne, Three Rivers, and St. Albans, is recycled at this new AD facility.
