Summary Energy from Waste (EfW) offers a means of generating usable energy from waste resources, which would otherwise go to landfill. The R 1 energy efficiency formula developed by the European Commission is widely used in the assessment of the thermal energy efficiency of an EfW facility. The assessment of the thermal energy efficiency of an EfW plant is critical as this determines whether the facility passes as an energy generation or disposal facility impacting on whether the facility pays waste levy or not. The adoption of the R 1 formula ‘as is’ disadvantages smaller‐sized plants and plants operating in warm climate regions, which impacts the heat demand as well as the efficiency of electricity generation. This study presents a review of a range of external factors, such as size and climate, and their impacts on the calculation of thermal energy efficiency. A key contribution is the development of mathematical relations to be used as sub‐criteria in conjunction with the European R 1 formula in considering the impacts of these external variants. Climate and size correction factors have consequently been developed, and a means of applying the R 1 formula to alternative end products such as biochar and biofuels has been proposed. The work offers a worked example to show how the sub‐criteria can be used in practice specifically in the Australian context. Copyright © 2016 John Wiley & Sons, Ltd.
