The increase in plastic and microplastic pollution in soils can cause adverse impacts on plants and microorganisms in the soil, which can in turn affect soil fertility. Microplastics affect soil ecosystems that are important for plant growth.
Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition.Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment and recycling.

Plastic recycling improves usage of resources. Biodegradable films need to be kept away from the usual recycling stream to prevent contaminating the polymers to be recycled. If disposed of in a sanitary landfill, most traditional plastics do not readily decompose. The conditions of a sealed landfill additionally deter degradation of ...
Only about 5% of plastic waste in the U.S. gets recycled. Scientists, lawmakers and even chemical companies themselves are trying to change that.
These particles originate from the degradation of larger plastics and are now found in various environmental matrices, including water, soil, and air. Given their minute size, nanoplastics can penetrate biological barriers and accumulate in human tissues, potentially leading to adverse health effects.
A plastic is considered biodegradable if it can degrade into water, carbon dioxide, and biomass in a given time frame (dependent on different standards). Thus, the terms are not synonymous. Not all bioplastics are biodegradable. [44] An example of a non-biodegradable bioplastic is bio-based PET. PET is a petrochemical plastic, derived from ...
A British scientist claims to have invented a plastic-free, ... A British scientist claims to have invented a plastic-free, single-use water bottle that can decompose within three weeks.
Bioplastics also cause carbon dioxide emissions from harvesting vehicles. [59] Other minor environmental impacts include high water consumption for biomass cultivation, soil erosion, soil carbon losses and loss of biodiversity, and they are mainly are a result of land use associated with bioplastics.
