The mulching sheets made from Sirmax bioplastic have passed open-field experimental tests, effectively entering the agricultural sector, where there are still many challenges to be addressed in terms of sustainability.
The materials analysed in this study aim to eliminate the release of microplastics from contact during the cultivation process. In fact, mulching sheets are mainly used to prevent weeds from growing in orchards, vineyards, vegetable gardens, etc.
The sheet under study is made of BioComp®, a formulation of biodegradable material certified as ‘Biodegradable Soil’ according to EN 17033:2018-3. The company's objective was to bring it to market by combining ‘traditional’ laboratory certifications with specific studies carried out in the open field.
The experimental tests carried out in the open field on mulching sheets are part of a research project carried out in collaboration with the University of Turin. The research project, for which Sirmax provided the materials for analysis, aims to study the behaviour of biodegradable plastics in agricultural soils.
The analysis showed that Sirmax's mulching film limited weeds throughout the entire corn growing cycle, with no difference in production compared to other methods. Micro-bioplastics in the soil decreased in the six months after harvest, suggesting possible complete biodegradation without negative effects.
