    Tudor Griffiths is a family business that traces its history back to 1874. Starting life in the building trade, it quickly diversified, building a quarry to extract sand and gravel for making concrete. Over the years, Tudor Griffiths has grown to meet the needs of different areas of its business. For example, it bought a string of builders’ merchants to meet its demand for cement, and it moved into landfill to make use of the void as the quarry emptied. With sustainability an important value of the company, it built a materials recovery facility (MRF) as recycling overtook landfill.

    How the landfill gas project started

    When Tudor Griffiths decided to host a landfill gas scheme on its site in 2009, it was just one of a host of projects that complemented the company’s core business areas. The renewable electricity generated powers the site and provides an additional income stream, so it was a win-win.

    It talked to two landfill gas operators, which both offered to manage the landfill gas operations on behalf of Tudor Griffiths. Since then, the landfill gas project has performed very well, and Tudor Griffiths' Group Finance Director, John Seaward, diligently monitors the monthly output, how much electricity has been used on-site and how much was exported to the grid. He says: “It's very straightforward. If any of the figures are unexpectedly high or low, I query them, and then raise an invoice."

    Time to review

    After 10 years, John decided it was time for a more detailed review. He explains: “We have a really positive relationship with our landfill gas operator but we were conscious that, after 10 years, there might have been changes that we weren’t aware of. We wanted to check the figures, but we didn’t have the expertise in-house.”

    John had had little joy in finding a royalty payment expert when Accounting for Energy got in touch. He said: “It was exactly what we were looking for. I was hoping to find an external specialist who would be able to confirm that the project was achieving its full income potential. Accounting for Energy exceeded my expectations.”

    People rely on the income over the course of the contract. But when you have no independent means of assessing this, it’s only common sense to ask an expert to check it for you.”

    What was our approach?

    All Accounting for Energy required to carry out the audit was the relevant paperwork. Tudor Griffiths provided a copy of this and Accounting for Energy simply did the rest – by working closely with Tudor Griffiths’ landfill gas operator to increase the project’s income potential, showing how well the project was performing in relation to other UK landfill gas sites and was contributing to the environment.

    John says: “Accounting for Energy spent a couple of months reviewing the data and producing their report. It was very easy to understand and highlighted several areas. I have to say that I was extremely impressed with their knowledge of the industry and they did a tremendous report. I’ve got a much better understanding since the audit took place, and more confidence that the project is now meeting its full income potential and how the project has performed in comparison to other UK landfill gas sites.

    “Accounting for Energy exceeded my expectations.”

    Environmental benefits

    Tudor Griffiths is an excellent example of a company seeking to bring sustainability into the heart of its business. It has received an income from landfill gas for the last 11 years and the electricity fuels the company's MRF, while the excess is exported to national grid.

    Since 2017, Tudor Griffiths has also operated seven biomass boilers and processes timber for sale as biomass fuel. Group Finance Director John Seaward says the environmental projects work well alongside each other and bring surprising benefits. “We try to make the most of the waste that comes through our site. The skip hire business and MRF are all about recycling, but we use the landfill gas to gain as much value as we can from the waste that can’t be recycled, that goes to landfill."

    “The landfill gas really appeals to the imagination of visitors. We run tours for local schools and organisations – we show them the quarry, the biomass and the MRF – and people are always really excited when we tell them that the electricity for the MRF is generated by the landfill gas engine.”

    Advice to other landfill gas site owners?

    While many site owners have a positive, long-term relationship with their landfill gas operator, John says there is nothing to lose from independently reviewing your project’s performance to date. He concludes: “Obviously, people rely on the income over the course of the contract. But when you have no independent means of assessing this, it’s only common sense to ask an expert to check it for you.”
