Estimation of microplastics entering agricultural soil through the use of biofertilizers
Summary
Scientists found that organic fertilizers made from food waste contain tiny plastic particles called microplastics, which end up in farm soil when the fertilizers are applied. These microscopic plastic bits can potentially enter our food chain through crops grown in that soil. This research helps us understand another way that plastic pollution might affect the food we eat, though more studies are needed to determine the actual health risks.
The use of biofertilizer from anaerobic digestion of organic waste in biogas companies provides a valuable nutrient source for agricultural soils and supports the circular economy. However, their use may also contribute to the input of microplastics (MPs) into soils, and data on this topic remains limited. This study investigated the abundance of MPs (
