Qualitative Studies of Selected Types of Composts
Summary
Researchers conducted qualitative morphological analyses of four compost types -- composted grass, backyard compost, soil improver, and commercial compost -- to characterize the fractions present in each. The study assessed the role of composting as a waste processing method and documented the physical composition of each compost type.
More and more waste is being generated in the world. One form of waste processing is the composting process. This work aims to study the morphological composition of selected composts to determine the amounts of the various frac-tions contained therein. In the present work, four types of composts are presented to study their morphological composi-tion. Composted grass, backyard compost, soil improver formed after composting green waste, and stabiliser – waste formed due to mechanical-biological processing of municipal waste taken from the Municipal Waste Mechanical-Biological Treatment Facility – were studied successively. Fifty samples of 2 kilograms each were taken from each group of composts, respectively. Each sample was divided into seven fractions: organic waste, plastics, ceramics, paper and cardboard, glass, metal and others. After analysis, it can be concluded that it is very difficult to obtain homogeneous compost due to the heterogeneity of the raw material. The results are accurately presented in tables with the distinction of the different fractions. It was found that mowed grass contained the most organic matter, while stabiliser contained the least. The least amount of plastic was found in backyard compost, and the most in stabiliser.

Microplastic Abundance in the Locally Produced Commercial Compost and the Characteristics
Researchers measured microplastic abundance in locally produced commercial compost, characterizing particle morphology, size, and polymer type. The compost contained measurable microplastic concentrations dominated by polyester fibres and polyethylene fragments, confirming that commercial composting does not eliminate microplastic contamination and may serve as a route for soil plastic input.
Identification and Quantification of Microplastics in Commercial Compost From a Wide Range of Composting Materials and Potential Environmental Impacts
Researchers identified and quantified microplastics in commercial compost derived from household waste, livestock manure, and vegetable straw using acid extraction, filtration, and FTIR spectroscopy. All compost types contained microplastics, with concentrations varying by feedstock type, raising concerns about microplastic introduction to agricultural soils via compost application.
Determination and quantification of microplastics in compost
Researchers analyzed commercially available compost products to determine how much microplastic contamination they contain. They found microplastics in all tested composts, with fibers and fragments being the most common forms, primarily made of polyethylene and polypropylene. The findings raise concerns that applying commercial compost to agricultural land may be an overlooked pathway for introducing microplastics into soil.
