Assess how resin tapping can induce changes in the physical, chemical, and mechanical wood properties of the trees, thus conditioning its technological suitability for certain uses and, consequently, its commercial value.
In the Doñana National Park in Andalusia, short-rotation coppice eucalyptus plantations occupy large areas and belong to private forest owners.
« Esencias Garcia-Palomo » distillery uses 5,000 kg of eucalyptus branches and leaves every day for its production of 10 to 40 kg of essential oil. Not being a forest owner, this resource is a cost to the company.
Mr. Palomo has organized with his neighbors to work in symbiosis and limit the costs of their respective operations : the collection of his raw materials contributes to the silviculture of coppices of eucalyptus.
Within the framework of the European project SustForest Plus for the revival of gemmaging in Europe, the Centre Régional de la Propriété Forestière de Nouvelle-Aquitaine has commissioned the technological institute Forest Cellulose Wood and Furniture to analyse the impact of resin extraction on the technological characteristics of pine wood (mechanical properties, drying, aesthetics, etc).
