摘要

In order to achieve a circular economy, there must be a greater understanding of the links between economic activity and waste generation. This study introduces the first version of the UK waste input–output table that could be used to quantify both direct and indirect waste arisings across the supply chain. The proposed waste input–output table features 21 industrial sectors and 34 waste types and is for the 2010 time-period. Using the waste input–output table, the study results quantitatively confirm that sectors with a long supply chain (i.e. manufacturing and services sectors) have higher indirect waste generation rates compared with industrial primary sectors (e.g. mining and quarrying) and sectors with a shorter supply chain (e.g. construction). Results also reveal that the construction, mining and quarrying sectors have the highest waste generation rates, 742 and 694 tonne per £1m of final demand, respectively. Owing to the aggregated format of the first version of the waste input–output, the model does not address the relationship between waste generation and recycling activities. Therefore, an updated version of the waste input–output table is expected be developed considering this issue. Consequently, the expanded model would lead to a better understanding of waste and resource flows in the supply chain.
