Day 1 – Wednesday 4th July
Purple Seminar
10.00 Feedstock Pre-Treatment
Pre-treating AD feedstocks has a number of important aims, including de-packaging, removing
contamination and improving biogas yields. After an introduction from Terry Brownhill, Eddie
simpson will discuss the benefits of a pre-digestion percolation and hydrolysis stage, with Chris
oldfield considering the benefits, and potential pitfalls, of shredding materials for AD.
Chair: Terry Brownhill, Eaton Management
Eddie Simpson, AMEC, Chris Oldfield, UNTHA UK
11.00 Biogas in Transport: the Roadmap
Using biomethane as a transport fuel offers huge greenhouse gas and particulate emission
savings, and it can be used in existing natural gas vehicles without the need for further
modification. That – and the rising price of diesel – is making it an increasingly attractive option,
particularly in the heavy goods sector where there are few alternative low-carbon options. A
number of obstacles to the sector still remain however: the infrastructure for gas refuelling is not
yet in place, and there is no direct incentive for biomethane producers to supply the transport
sector. in this session Andrew will present ADBA’s strategy for advancing the sector, steve will
discuss the full results of Coca-Cola’s trial of biomethane trucks, while Chris will consider his
experience of the transport fuel market and how it is developing.
Chair: Andrew Whittles, low Emission strategies
Steve Carroll, Cenex, Chris Nash, gasrec
12.00 Environmental Permitting for AD
Environmental permitting can be a complex and difficult to understand process. Howard leberman
will give an overview of the latest developments and guidance from the Environment Agency, while
stephen Barnes will give his experience from supporting projects through the permitting process.
Howard Leberman, Environment Agency, Stephen Barnes, Wardell Armstrong
12.55 LUNCH
14.00 Developing Smarter AD
Developing AD projects quickly, sustainably and cost effectively is the ultimate goal of those
responsible for managing and delivering AD projects. Using the latest in science, engineering
and economics, steve Broome will introduce CPi’s AD Development Centre which is designed to
help organisations of all sizes to develop anaerobic digestion (AD) processes for conventional
and novel waste streams. Mark Bedford will outline how computational process modelling can
assist in the delivery of AD facilities in the waste sector using a short live demonstration of an
operating waste plant.
Steve Broome, CPi, Mark Bedford, Wardell Armstrong
15.00 Optimising Digester Performance
Maximising gas yield and quality digestate production are critical to the success of an AD plant.
in this session, Andy Mail will talk about the benefits of percolation as a pre-treatment method
and the addition of molasses into the digester, Ray long will present on the field trial results of
Citadel’s Biocat+, Eilert Balssen will consider how mixing can be optimised based on viscosity,
while gunnel Hagstam will examine how the treatment of household waste can be optimised.
Andy Mail, AMEC, Ray Long, Citadel, Dr Eilert Balssen, Xylem Water solutions,
Gunnel Hagstam, Kemira Chemicals
16.00 R&D Taster Session: Optimising Bacteria
The latest academic developments on how AD projects can use innovative techniques to optimise
bacteria will be outlined by sandra Esteves, who will explain how digesters can be controlled
through microbial profiling, and shane Carter, who will outline how natural occurring anaerobic
bacteria can be used as digester inoculums.
Dr Sandra Esteves, University of glamorgan, Shane Carter, interface Chemistry

10.00 Morning Debate: The Range of AD Technology
AD is a wide-ranging technology able to treat a variety of organic feedstocks – which is not
always well understood. Dorian Harrison will chair a debate on what type of technology
works best in what scenarios, with Robin szmidt, Amaya Arias-garcia and Tina Wolter giving
examples of projects they have been involved in. They will consider the range of ‘wet’ and ‘dry’
technologies, and what buyers need to consider when choosing which technology to use.
Chair: Dorian Harrison, Monsal
Robin Szmidt, Kuettner UK, Amaya Arias-Garcia, Tamar Energy, Tina Wolter, siTA UK
11.00 Procuring AD Technology
With a huge range of potential suppliers and technologies available for every part of the
AD process, it can be difficult to know where to start. However, making good decisions in
procurement is critical to project success. The technology needs to be right for the feedstock and
location, and you need to have confidence that it will operate efficiently and to its potential. Nick
Churchward, Andrew Jenkins and Hugh Bulson discuss the issues you need to consider, and
the questions you need to ask of suppliers.
Chair: Nick Churchward, Burges salmon
Andrew Jenkins, Zebec Biogas, Dr Hugh Bulson, organic Resource Agency
12.00 Making Better Use of Heat
Making the most efficient and effective use of the products of the AD process is paramount
to the success of the industry, and heat from CHP is no exception. This session will consider
innovative ways of using heat produced, including a presentation from steve Richmond on the
use of AD in district heating systems, a discussion from Hans Wain on how heat can be used to
generate extra electricity and a paper from Jos Van Buijtenen on how the organic Rankine Cycle
(oRC) can be integrated into the AD process.
Steve Richmond, Rehau, Hans Wain, ElectraTherm, Jos Van Buijiten, Triogen
12.55 LUNCH
14.00 Focus on Digestate: PAS110 and the Future of End of Waste
Five AD plants in the UK are now accredited under PAs110, the end of waste specification which
guarantees that digestate produced is of a high quality and can be applied to land without being
subject to waste regulations. However, some AD operators have encountered difficulties complying
with the requirements of the specification and achieving PAs110 status. Becky Arnold will discuss
the experience of Biogengreenfinch in meeting the specification, while Nina sweet will give an
update on the future of PAs110, in the context of a current review of aspects of the specification,
and proposals for Europe-wide end of waste legislation.
Becky Arnold, Biogengreenfinch, Nina Sweet, WRAP
15.00 Focus on Digestate
There is little doubt that digestate is currently under-valued, and that developing markets
for the material is important for the future of the AD industry. This session, introduced by
WRAP digestate specialist David Tompkins, will consider market development work such
as that undertaken by Howard Robinson, research into the effect of digestate on soils with
a presentation from John Walsh, and technological developments such as Huber’s work on
plastics removal.
Chair: David Tompkins, WRAP

Tony Clutten, Huber Technology
16.00 Biogas Upgrading Technology
The wide range of biogas clean-up and upgrading technologies will be considered in this
session, alongside the issues around network entry facilities, the barriers to grid entry and the
potential for pressurising gas ‘uphill’. stephen McCulloch and Coen Meijers will discuss their
grid injection projects, at stockport and Poundbury respectively, which are set to come online
this summer, while Alison Cartwright will provide a comprehensive outline of the requirements
and equipment needed for a developer of a biomethane to grid project.
