I have great pleasure in recommending E4tech to future clients. ETI has worked with E4tech since 2010 across a number of Bioenergy-related projects, encompassing a variety of technical, economic and environmental analyses of the UK bioenergy sector. The most significant piece of work has been the development of the ETI’s Bioenergy Value Chain Modelling toolkit – a circa £1.3 million project led by E4tech. I particularly value E4tech’s attention to detail, thoroughness, speed of working and ability to challenge – both on approaches taken and conclusions drawn.
