ABSTRACT
The plastic industry has witnessed substantial growth since the 1950s, evolving into one of the most prominent sectors in society. This expansion can be attributed to the favourable characteristics of plastic, including durability, malleability, lightweight nature, and cost-effectiveness. Despite its various advantages, concerns have emerged among researchers regarding the environmental repercussions of plastic, primarily due to inadequate end-of-life cycle treatment, low recyclability and reusability rates, and the high likelihood of breaking down into microplastics. The utilization of sewage sludge as a soil amendment can introduce microplastics into the environment. Plastic mulches, typically composed of polyethylene, do not readily degrade in the soil, leading to the accumulation of plastic residues. Soil solarization, being considered as important sterilization method using plastic film mulch can also generate significant amounts of plastic waste. The presence of plastic waste on the ground can have adverse effects on the characteristics of soil. Additional research is required to examine the immediate and prolonged impacts of microplastics on the dynamics of organic matter in soil, the microbiome of soil, enzymatic activity in soil, and the potential consequences for human well-being
