Abstract:
Viticulture is mostly affected by a continuous use of copper-based fungicides to contrast fungal diseases. This treatment, used in both traditional and organic cultures, results in a considerable accumulation of Cu in the top soil, then into plants and soil biota. Furthermore, Copper tends to migrate into air, water and soil ecosystem, posing serious threats to the environment and human health because of its toxicity. At the same time, vineyard pruning represent a valiant woody biomass source for renewable energy production through gasification, the thermochemical process where carbonaceous material is converted into a gaseous flammable fuel called syngas. Currently, one of the important challenges for bioenergy production through gasification is the management of heavy metal-contaminated biomasses used as fuel. This study is aimed to investigate the distribution of copper through thermochemical conversion chain of wood grape, from biomass to electrical and thermal energy production. Starting to the amount of Cu based fertilizers applied to traditional and organic viticulture, the heavy metal residues have been checked and analyzed into ashes biomass derived, into gas emissions coming out from PP20 gasifier and into biochar as gasification process by-product. Inductively coupled plasma mass spectrometry (ICP-MS), and X-ray Fluorescence spectroscopy (XRF) methods have been performed in order to quantify the amount of residual Copper into the different tested arrays. The assessment of Cu persistence along the thermochemical treatment chain of grape biomass is provided.
