Scottish Aggregates Survey 2012

Distribution

12. Table 3 primarily shows that, with the exception of Highland, around 85-90% of crushed rock is retained in the area where it was produced, with the North East of Scotland and Western Isles retaining between 99-100% of the material they produce. Again, the Highland figures will be strongly influenced by Glensanda. The SESplan area, North East Scotland, TAYplan area and West Central Scotland A all imported crushed rock with the SESplan area needing to import 17% to meet demand.

13. Distribution of sand and gravel shows a slightly smaller proportion of product generally retained in the region. The SESplan area was a significant importer of material with, overall, a significant proportion of material being supplied from sites outwith the region. Overall, exports to England from Scottish quarries was nearly 5 mt. These exports will be predominately from Glensanda with smaller contributions from other sites.

TABLE 3: DISTRIBUTION

14. The import and export figures are shown as region to region flows in Table 4. These confirm that the majority of the flow of material in the SESplan area for both crushed rock and sand and gravel is from the neighbouring West Central Scotland A &B (and Dumfries and Galloway) and TAYplan regions. Elsewhere, the figures show that flows between neighbouring regions are common and highlight the need to adopt a cautionary approach when identifying "market" area.
