The Authors tested a new mini-baler system designed for the recovery of pruning residues in vineyardsinaccessible to conventional tractors. Under these conditions, growers manually take the residues to thefield edge and burn them there. Such practice is expensive, and generates substantial emissions. Use of thenew mini-baler system would substitute burning, with significant advantages on air quality and landscapeamenity. The system works well, but productivity is low (mean 0.38 t per scheduled machine hour) andbaling cost still too high (mean 80 € t?1). Productivity can be increased and cost decreased through abetter preparation of the residues before collection. Farm use of the baled product may dramaticallyincrease value recovery and is facilitated by the availability of newly designed boilers. The versatility andthe small purchase cost of the mini-baler makes it an ideal machine for those cases where labour cost islow and investment capacity is limited.
