Valorization of wine industry by-products
The project aim is the evaluation and the application of innovative technical solutions, for the use of by-products and wastes of winemaking sector to turn into energy, nutraceutical coproducts and fertilizer for a sector higher productivity and a lower environmental impact. In particular, the project will focus on following specific aims/opportunities:
- Recovery and characterization of vine leaves for extraction of bio-active compounds;
- Recovery, quantification and gasification of pruning sarments/dregs for energy purposes;
- Recovery and re-use of ashes and biochar for agronomic purposes;
- Extraction of copper from ashes and biochar, obtained from gasification process.
The project is composed of 3 work packages. The first one provides detection of varieties of Emilia Romagna region, potentially richer in bio-active ingredients in leaves and grape pomaces and chemical-physical analysis of them but also the development of a methodology for leaves recovery. The second work package consists in collection and characterization ofvine pruning wood and use of pruning sarments and grape pomaces in enterprise-scale gasifiers for energy production. the third work package provides agronomic and oenological evaluation of biochar obtained by local varieties pruning sarments and recovery of metallic copper from ashes and re-use in vineyard for defense against downy mildew.
The expected results are:
- Obtaining of pure active ingredients, extracted from vine leaves and grape pomaces, with high added value for nutritional and health uses;
- Increase of availability of raw materials (winemaking by-products) in lieu of energy crops;
- Development of a gasification process of pruning sarments combined with grape pomaces to optimize biomass pre-treatments and operating parameters;
- Estimates of reduction and/or cancellation of fossil origin energetic vectors in the cellars through valorization of pruning sarments for electrical and thermal energy;
- Increase of oenological grapes properties thanks to biochar use, a cheap quality substrate and which has ah higher fertilizer value for soil improvements od vineyards;
- Reduction of chemical fertilizer intake and increase od environmental sustainability of the crop;
- Increase of stocked carbon amount in soils through progressive increase of biochar use;
- Development of practical strategies for recovery and re-use of copper cointained in ashes resulting from gasification process.
Different realities. operating in mechanical, food, nutraceutical and field, can reap benefits from project activities, that will be:
- Definition of work sites (tractors-strippers) will allow to mechanical
enterprises to obtain an useful instrument to perform any constructive improvements on their
machines;
- Ability to access, for food and nutraceutical entreprises, to new sources of biomoleculesfrom specific wine industry by-products;
- A more profitable exploitation, for wine entreprises, of by-products with higher profits (bio-active ingredients, thermoelectrical energy production, biochar and re-use of copper).
