CORONEL DE RENOLFI, M.; DIAZ, F.; CARDONA, G.  and  RUIZ, A. P.. Times, lumber recovery and costs of sawing process of Prosopis alba in Santiago del Estero, Argentina. Quebracho (Santiago del Estero) [online]. 2012, vol.20, n.1, pp.15-28. ISSN 1851-3026.

The Prosopis alba wood is one of the most sought after by furniture manufacturers, due to, among other qualities, its excellent grain and nobility that enables processing without drying. In Santiago del Estero, there are not studies about lumber recovery, productivity and costs of sawn timber in general or in particular Prosopis alba. Therefore an evaluation of the working times, lumber recovery and productivity of sawing process was carried out into ten small sawmills from Santiago del Estero province. The aim was to estimate the costs of sawing. For this purpose, 40 logs of Prosopis alba with a volume of 9.47 m³ without bark were sawed. These logs generated 260 boards of different dimensions with a sawed volume of 5.59 m³, indicating a lumber recovery factor of 58% with bark. The average time process was 920 seconds. Productivity was established in 232 ft²/h. The direct cost of sawing amounts to $2.33/ft².
