“…In SB2, the results are presented without accounting for the EoL of the MPs and the biobased infill entering the sea due to unsatisfying data. Nevertheless, the respective EoLs were explored in the SA, focusing on climate change and the ecosystem damage induced as we assumed that greenhouse gases such as carbon dioxide, methane, and ethylene were the main degradation products for both infill types, which was confirmed by several recent works [41][42][43][44][45].…”

Recently, the European Commission announced their intention to restrict intentionally added microplastics to reduce the amount emitted by 0.5 million tons per year. Findings on microplastics indicate toxic behavior for biota, yet many mechanisms remain in the dark. Microplastics also pose a challenge in life cycle assessment as methods are actively being developed. Considering this recent decision, an anticipatory life cycle assessment was performed, comparing the impacts of natural grass pitches with artificial grass pitches using bio-based infill materials as well as polymeric ones made from recycled and virgin materials. The aim was to confirm if microplastics are in fact a considerable environmental hazard when compared to more traditional impacts. The microplastics’ impact was modeled after the MarILCA group’s work on the new midpoint of physical effects on biota. The results showed that the influence of the microplastics remains negligible when using the method provided. For most midpoint categories, the wood-based infill showed the best results, often closely tied with the infill made from recycled rubber from tires. A sensitivity analysis revealed that neither the physical effects on biota nor the greenhouse gas emissions from degradation in a marine environment are deciding factors when assessing the endpoint of ecosystem damage.
