Biological treatment of organic waste, mainly green waste, into fertilizers and their application to agricultural land is a common practice that promotes the return of nutrients to the soil and increases soil fertility. However, green compost can potentially be a source of microplastics and contributes to their release into the environment. Microplastics in green compost are mainly formed due to the incomplete decomposition of bio- and oxodegradable waste disposal bags (Markowicz & Szymańska-Pulikowska, 2019). In addition, accidentally caught plastic waste breaks down during the mechanically pre-treatment of green waste such as shredding and sieving and turns into microplastics. Post-treatment of compost, such as sieving, can significantly reduce but never wholly remove microplastics (Weithmann et al., 2018). Weithmann et al. (2018) investigated large (1−5mm) microplastics in several organic fertilizers after the biological treatment of organic waste. According to their investigation, microplastics amount varies from 0 for fertilizer after energy crop digestion till 895 particles per kilogram dry weight in commercially available fertilizer from a second biowaste digester. Braun et al. (2020) found that compost application to agricultural fields goes along with plastic loads of 84,000 to 1,610,000 plastic items ha-1 a-1 or from 0.34 to 47.53 kg plastic ha-1 a-1. The presence of microplastics in the soil after compost application was confirmed by Watteau et al. (2018). This work aims to develop a general algorithm for microplastics quantification in green compost samples and determine the concentration of microplastics in real green compost samples. For this investigation, green compost samples were taken from the Alytus MBT facility. The primary substrates for this compost production are wood, biodegradable garden and park waste collected from city Alytus and neighboring regions. Green waste is composted in long rows (windows) due to the technological process's simplicity and cheapness. Ready compost is used ... |
