Conversion to biogas could reduce emissions and save more than £400 million a year in fuel costs.

Industrial players currently face a double challenge: how can they battle increasing costs for energy and reduce emissions at the same time. This double challenge has also been the main topic of the Business Breakfast organised by Bilfinger, one of the leading international providers of industrial services in Eastern Europe, in Bucharest this May. Bilfinger experts discussed with representatives of major industrial investors what the challenges are and how to ensure that their operations are energy efficient or even self-sufficient.
