The purpose of the study was to provide good quality data on the likely tonnage of co-mingled recyclate material arising, in the short and medium term arising from anticipated changes in the Local Authority recyclate collection schemes in Scotland. The purpose was also to provide a regional analysis of the potential level of investment required to process this tonnage if new, best practice MRFs are to be developed. The study was conducted in three phases:
1. Local Authority survey to identify Councils considering changing their main scheme to a co-mingled scheme.
2. Modelling of total yields from the identified additional co-mingled schemes to quantify the potential tonnage of material requiring processing at MRF.
3. Calculation of the capital and ongoing operational costs for the new MRF facilities potentially required on a regional basis using the Remade MRF model. This has been reported as a cost per tonne.
