Sirmax Group’s biodegradable plastic mulching films have been tested in open-field studies with the University of Turin to assess their impact on agricultural soil. The films, certified as “Biodegradable Soil” under EN 17033:2018-3, were applied to corn crops for a year to compare their performance and potential environmental impact. The results showed that the films successfully controlled weed growth throughout the crop cycle, with no significant differences in yield between mulched, chemically weeded, and non-mulched corn. Analysis of the soil also revealed a decrease in micro-bioplastic concentration six months after harvest, suggesting that the film could potentially biodegrade completely. The study aims to provide scientific backing for a product that can contribute to more responsible management of natural resources in agriculture. The collaboration between Sirmax and the University of Turin serves as an example of industry-academic research partnership dedicated to developing sustainable solutions. The results of this study have the potential to provide an alternative to traditional plastics used in agriculture, reducing soil pollution and waste.
Field tests reveal that biodegradable mulching films emit significantly fewer microplastics.
