Composting or anaerobic digestion of the grass mowed along roadsides is developing in France, but little information on grass contaminants (heavy metals and organic compounds) is available. During the CARMEN project, roadside grass was sampled in different locations in western France, during different mowing periods (spring and autumn) to evaluate the traffic load and seasonal influences. The project also involved other operations not detailed here: pilot anaerobic digestion tests and a cost-benefit study of mowing and exporting the grass to an anaerobic digester.
