Compostability and vermicompostability of greaseproof wrapping paper

Popis výsledku v původním jazyce

This study aimed to determine the compostability of greaseproof wrapping paper and evaluate the resulting product according to legislative requirements. The paper with amendments was composted in a GreenGood electric composter and vermicomposted in a Worm Factory vermi-composter. The resulting p Eta and electrical conductivity (EC) values indicated that the material from the electrical composter was not suitable for fertilization. This was because of the presence of acidic and salted composted substrate from the gastro-waste in the initial mixture. Conversely, an electric composter was suitable for rapidly reducing paper waste. The mixture with paper, ap-ple pomace, and horse manure had 90% of particles smaller than 9 mm and 5 mm after 24 and 48 h of composting, respectively. In vermicomposting, these parameters were reached after two to three months. Vermicompost in comparison with compost showed greater pH (7,4-8,8) and lesser EC (405-1046 mu S/cm). The greater macroelements contents in the compost were positively influenced by a 50% proportion of the composted substrate in the initial mixture. Nevertheless, a vermicompost based on paper and horse manure exhibited the greatest nutrient content of all the assessed variants. According to the phytotoxicity test, it was a well-matured compost. Grease-proof paper used for food packaging is both compostable and vermicompostable. The disintegra-tion results can be inferred when the legislative standard was met in all cases.
