Tree cuttings a possible alternative energy source
- EFE. VALENCIA | TRANSLATION: NATHAN READ (CNAI)
Researchers at the Universitat Politècnica de València (UPV) have carried out a pioneering study into the heating potential of tree cuttings after the trimming of urban species such as mulberry trees, banana trees, palms and acacias and have found that they can be used as an alternative source of energy.
The study into the potential use of trimming residues has been carried out with samples from Valencia,Mislata, Gandia and L'Alcudia and the results have been published in the Renewable Energy magazine.
Borja Velázquez Martí, reseacher from the Mechanised and Technological Agriculture Group of the UPV, explained that different predictive models of residual biomass quantities from the different species that inhabit the area have been developed.
For this reason, both manual and laser detection methods were used, which analyse variables such as volume of foliage, trunk diameter or tree height, among others.
From these variables, mathematical and computerised models were obtained which relate these parameters to biomass quantities, said Velázquez Martí.
In the study, the reseachers determine the heating power of each species, its carbon, hydrogen, nitrogen, sulfur and chlorine composition, among other components.
