Energy and ecological optimisation of the belt conveyors’ operation

The article aims to discuss the energy consumption and environmental impact of the conveyor belts and how they can be improved, as well as to analyse the methods used in assessing energy intensity and noise and dust emissions into the environment. Design/methodology/approach The study analyses the applicable legal requirements and the tools used to assess energy intensity and emissions and then presents the results of an assessment undertaken at a selected power plant. Findings In the analysed power plant, measures must be implemented to minimise energy intensity and noise emissions. However, different methods are used to assess the scopes of operation, which hinders optimisation in an integrated sense. Practical implications An integrated approach in assessing the performance of different conveyor belts can provide the foundation for optimising many belt conveyor systems used in the Polish power industry. Originality/value The study’s results confirm the lack of a standardised methodology for evaluating the operation of conveyor belts that considers their energy efficiency and individual emissions. They are the starting point for developing an innovative algorithm for the multi-criteria evaluation of individual system components, ensuring their integrated characterisation and, as a result, integrated optimisation.
