Aim of the research is the development of biodegradable polymeric materials based on hydrolyzed proteins, derived from waste products of the leather industry. These compostable and biodegradable materials are used in order to made biodegradable mulching films. Fillers, coloured pigments, natural plasticizer and vegetal fibres were opportunely added inn order to assure the chemical, physical-mechanical properties of the film during the cultivation time. Soil mulching films, made with the biodegradable materials, were applied to the soil by means of spray techniques; the mulches were tested in an ornamental cultivation carried out inside a greenhouse. The innovative biodegradable spray films lasted in the field up to 12 months, keeping their mulching effect and guarantying weed suppression.

L’obiettivo della presente ricerca è lo studio e lo sviluppo di nuovi materiali polimerici biodegradabili a base di risorse rinnovabili, in particolare proteine idrolizzate derivate da prodotti di scarto dell’industria conciaria. Tali materiali, completamente biodegradabili e compostabili, sono stati applicati per la realizzazione di teli per la pacciamatura del suolo. I materiali biodegradabili utilizzati per la pacciamatura possono essere addizionati di fibre naturali, fillers, pigmenti e plastificanti, in modo tale da modularne le proprietà fisico-chimiche e meccaniche. Tutti i materiali sono stati realizzati con lo scopo di ottimizzare le loro proprietà fisico-meccaniche per la loro applicazione in campo. Mediante test in serra è stata accertata la loro idoneità e funzionalità, i film di pacciamatura sono stati realizzati direttamente sul suolo agrario mediante tecnica spray a bassa pressione. I film hanno mostrato, in campo, una vita utile di circa 12 mesi e hanno soddisfatto la loro funzione pacciamante, riducendo drasticamente lo sviluppo di erbe infestanti
