Waste heat recovery technologies and applications

It is estimated that the UK industrial sector consumes as much as 17% of the overall UK economy's energy consumption and generates about 32% of the UK's heat-related CO 2 emissions. From this value and as can be seen from Fig. 1, 72% of the UK industrial demand is from industrial thermal processes of which 31% is classified as low temperature process heat and almost 20% of that or 40 TWh
