These include owner’s engineer roles for Material Recovery Facilities (MRF), providing expert opinion on mechanical processing for a number of waste streams, due diligence, feasibility studies for waste treatment technologies and more. Adam is also a technical advisor to WRAP (Waste Resource Action Programme) on MRF operation as part of a framework agreement. In addition Adam has lead projects exploring new and developing sectors in the waste market deploying alternative waste treatments such as the capture and deployment of aquaculture waste sludges and treatment of absorbent hygiene products. This has given him a wide view of approaches to waste processing across a range of sectors and applications.

EXPERT WITNESS EXPERIENCE
Adam has been an expert witness since 2019, applying his technical knowledge and experience to a range of commercial disputes. Adam has been required to read and digest large quantities of technical data, project data, regulatory position and anecdotal accounts in order to fully understand and appreciate the details of each case. Adam has reviewed evidence submitted by the opposite party and provided analysis and opinion to allow barristers and lawyers to understand the issues and prepare counter arguments. He has written clear and well-reasoned expert reports which have been submitted to the court as part of the dispute resolution process and has given evidence in Court under cross examination.

Adam has provided expert opinion in several different areas, principally on the composition of waste and suitability for the process at hand, and the suitability of certain waste processing systems and technologies for the duty and waste type.

Adam leads a team of senior engineers with a combined experience covering a wide range of waste processing technologies including energy from waste (EfW), anaerobic digestion (AD), advanced conversion technologies (ACT) including gasification, pyrolysis and waste to liquid bio-fuels, Mechanical Biological Treatment (MBT), composting including in-vessel composting (IVC), materials recovery facilities (MRF).

Adam is technical lead for mechanical processing technologies and as such is involved in a range of projects primarily related to mechanical sorting processes but including other mechanical elements such as incinerator bottom ash handling and materials handling. Adam has worked on projects both in the UK and around the world including Australia and the Middle East.

Before joining Ricardo Energy & Environment, Adam was a Senior Process Engineer with Biffa Waste Services at their £120m West Sussex MBT plant comprising of mechanical treatment and anaerobic digestion to process over 300,000 tonnes of household waste. Adam oversaw a number of elements of the commissioning and acceptance testing of the facility, then worked to ramp up the plant to full contract service delivery and ensure steady state operation of the plant. Prior to that Adam worked for Shanks Waste Management (now Renewi) on several of their large PFI waste treatment projects utilising MBT technology, including mechanical sorting, anaerobic digestion (AD), biodrying and autoclaving. Adam also lead the technical aspect of a number of smaller PFI and privately financed bids for waste treatment projects in the UK.
