The engineering firm ABT collaborated with Interland Techniek, to develop an air treatment technique (Eleminair) to make this possible. The air cleansing solution even won Netherlands' most prestigious engineering prize, De Vernufteling 2020, awarded by Koninklijke NL Ingenieurs! (Royal NL Engineers).
