The regeneration of brownfield land to greenspace is a governmental policy objective of many European countries. Healthy vegetation establishment and growth is an essential component of successful greenspace establishment, and research has shown that a planting medium of an appropriate standard for supporting vegetation can be created through amendment of soil-forming materials with organic wastes. However, failed regeneration projects suggest that barriers may exist that prevent the use of suitable quality soil materials. The aim of this research was to identify barriers to the use of organic wastes for improving soil materials for brownfield regeneration to community woodland. We conducted interviews with a range of professionals experienced in regeneration to greenspace, and used content analysis on interview transcripts. A diverse set of barriers was revealed, including a low technical awareness among some professional groups of how to improve soil quality, coupled with a low awareness of the published technical guidance. Other barriers include regulatory and project management issues, which influence the timings and economics of raising brownfield soil quality. We highlight areas in which future efforts may be focused to improve the quality of planting media used in land regeneration. Such effort will improve the sustainability of greenspaces created and complement effective management of organic waste streams.
