Green Circle, led by Oliver Hart, employs a small, but dedicated team of designers and project engineers operating from the CIDO Innovation Centre in Northern Ireland as well as from our pilot /toll drying facility at Navan in the Republic of Ireland.


We specialise in “solution driven” designs for plant & equipment based on our new generation Pulse Combustion (PC) and Spouted Fluid Bed (SFB) drying technologies employing novel applications of low pressure superheated steam (SHS) as the “core technology”.
