**Summary:** This study investigates the presence and characteristics of microplastics (MPs) in commercial compost, highlighting their potential environmental and health impacts. MPs were identified in compost samples from four different brands, with a total of 160 particles per 200 grams of compost. The MPs varied in color (red, yellow, black, white, and blue), size (0.06–1 mm), and shape (fragments, fibers, and filaments). The majority of the MPs were fragments, with a significant proportion being PET (polyethylene terephthalate), a common plastic used in textiles and packaging. The study found that MPs in compost could pose risks to soil health and human health, as they can be absorbed by plant roots and enter the food chain. The presence of MPs in compost is a growing concern, as their use in agriculture may lead to contamination of farmland and food sources. The study emphasizes the need for further research to develop effective methods for the removal of MPs from compost and to assess their long-term environmental and health impacts. The findings underscore the importance of monitoring and managing MPs in compost to prevent potential harm to ecosystems and human health.**Summary:** This study investigates the presence and characteristics of microplastics (MPs) in commercial compost, highlighting their potential environmental and health impacts.
