Who we are and what we offer
Together Everyone Achieves More.
Michael is a Cambridge engineering graduate who, after a short time in the nuclear industry, set up his first AD business Farmgas at the age of 22. Since then he has established himself as one of the UK’s leading experts in AD building over 140 AD plants, from 50kW to 1.5MW, including pioneering the AD of food waste in the DEFRA demonstration plant at Ludlow during his ownership of Greenfinch. He continues to run his own AD plant ‘BMAD’ from home on locally collected food waste.
Michael has been a board member of the REA for 7 years and for the past year has acted as Chair of the Policy Board. A visiting professor at the University of Southampton, Michael remains influential within the industry at an education level, an advisory level and on the ground with the on-going development of his small scale plug flow system.
Phil is entering his 10th year in AD and leads the project management and business development sides of the business. Phil has an in depth knowledge of Anaerobic Digestion process, but with the ability to translate this information to the client in user friendly terms.
He successfully managed the build of one of the UK’s first plug flow digesters in Northamptonshire from the first spade in the ground through to the final stage of commissioning. In his days with BiogenGreenfinch he led the bid team, with Michael as his technical lead, which was successful in winning 3 out of the 6 Welsh Assembly AD projects.
Phil has won over 25 contracts for the innovative plug flow system and continues to grow the business whilst managing the Company’s current projects.
Heather manages the administrative side of Lutra and is your first point of contact in our offices at Barrett’s Mill.
With a degree in Geography (BA Hons) from Aberystwyth University she has worked as a head receptionist and in business banking prior to joining Lutra. Heather's role includes the day-to-day running of the offices, assisting with the monitoring of the on site AD plant BMAD and liaising with local producers of food waste. She is continuing to increase her knowledge of AD with a focus on elements of CDM during the pre-construction and construction phases whilst assisting with scheduling and procurement.
Available daily to answer or forward email enquiries, Heather is office based Monday 8:45-17:00, Wednesday 14:00-17:30 and Friday 8:45-17:00.
Martin is our CAD draughtsman, preparing 3D models and layouts for customer approval, and also detailed drawings for costings and for production.
He has many years experience in both production and development engineering, working in various types of industry.
Edmund was our summer intern, recently graduating from University College London with a Chemical Engineering (BEng) degree. Following his time at Lutra, Edmund intends to continue his Chemical Engineering (MEng) programme at UCL.
Whilst interning at Lutra, Edmund’s main focus was to gain first-hand experience in the contracting industry and project management, as well as familiarising himself with the anaerobic digester systems specialised at Lutra. Edmund also integrated engineering knowledge from his degree with critical thinking and analysing skills to provide effective solutions for complex problems. Edmund achieved his goals by being directly involved with the commissioning of various projects and operation of the BMAD system during his internship with Lutra.
What We Do
Lutra provides clients with the design and project management of AD plants with site and user specific variables taken into account throughout the project. Lutra is keen to engage and involve clients in their build to a level to suit them individually. Commitment to the use of familiar trades people where appropriate alongside established industry specialists ensures the highest quality build and successful project delivery. A focus on small scale, farm based AD and community led AD projects are the areas in which Lutra excels, providing accessible planning, high quality design and cost effective completion.
Plug flow technology – Lutra’s preferred plug flow design provides the optimum hydraulic residence time (the time allowed for the conversion of the organic dry matter to biogas) ensuring that the micro-organisms are given enough time to complete their natural process. This is considered to be the most effective method of digestion, particularly for smaller scale plants, and maximises the financial returns for our clients.
Food Waste AD
Lutra has built its own small scale plug flow digester for food waste at its premises near Ludlow and we are working with local businesses and festivals to collect and process food waste and compostable materials. Removing unnecessary food waste transport and preventing resources going to landfill, local AD can turn waste into renewable energy, and to a project specific scale and capacity. Ongoing research explores the limitations of small scale AD monitoring feed stock variables and subsequent outputs. If you are locally based we can offer food waste collections to suit your business needs, be it weekly, twice-weekly, monthly or even one-off events we are here to help.
Its pioneering technology and scale provides an ideal model for small community and commercial plants between 20 and 50kW.
