  pages={61 - 65}
Plastic pollution accumulating in an area of the environment is considered “poorly reversible” if natural mineralization processes occurring there are slow and engineered remediation solutions are improbable. Should negative outcomes in these areas arise as a consequence of plastic pollution, they will be practically irreversible. Potential impacts from poorly reversible plastic pollution include changes to carbon and nutrient cycles; habitat changes within soils, sediments, and aquatic… Expand

Achieving net-zero greenhouse gas emission plastics by a circular carbon economy
A bottom-up model that represents the life cycle of 90% of global plastics is developed and shows that net-zero emission plastics can be achieved by combining biomass and carbon dioxide utilization with an effective recycling rate of 70% while saving 34 to 53% of energy. Expand

It is concluded that the low dose of MPs in the soils has a negligible effect on the production of CO2, but this factor should be considered in evaluating the global C budget in future research as this contaminant reaches a certain threshold. Expand

Predicted growth in plastic waste exceeds efforts to mitigate plastic pollution
Assessment of three broad management strategies, plastic waste reduction, waste management, and environmental recovery, at different levels of effort to estimate plastic emissions to 2030 for 173 countries found that 19 to 23 million metric tons, or 11%, of plastic waste generated globally in 2016 entered aquatic ecosystems.

Marine plastic pollution as a planetary boundary threat - The drifting piece in the sustainability puzzle
Abstract The exponential increase in the use of plastic in modern society and the inadequate management of the resulting waste have led to its accumulation in the marine environment. There isExpand
The Global Plastic Toxicity Debt
There is a toxicity debt that is incurred by having large amounts of plastic currently in the environment, exposed to degradation, but that has many more years of decay and release of toxic compounds to follow, and this debt is called toxicity debt. Expand
Evaluating scenarios toward zero plastic pollution
To avoid a massive build-up of plastic in the environment, coordinated global action is urgently needed to reduce plastic consumption; increase rates of reuse, waste collection, and recycling; expand safe disposal systems; and accelerate innovation in the plastic value chain. Expand
Reducing Uncertainty and Confronting Ignorance about the Possible Impacts of Weathering Plastic in the Marine Environment
Plastic in the global oceans fulfills two of the three conditions for pollution to pose a planetary boundary threat because it is causing planetary-scale exposure that is not readily reversible.Expand
Plastics in soil: Analytical methods and possible sources.
Current knowledge on available methods for the quantification and identification of plastic in soil, the quantity and possible input pathways of plastic into soil, and its fate in soil are reviewed are reviewed to ensure the applicability of these methods for soil needs to be tested. Expand
Can microplastics pose a threat to ocean carbon sequestration?
Th threats of marine microplastics to ocean carbon sequestration are discussed and the potential scale and scope of this impact is explored, and its underlying mechanisms are explored. Expand

An extensive literature search reviewed the current state of knowledge on the effects of marine debris on marine organisms, finding that where marine debris combines with other anthropogenic stressors it may affect populations, trophic interactions and assemblages. Expand
Environmental fate, toxicity and risk management strategies of nanoplastics in the environment: Current status and future perspectives
This review provides a state-of-the-art overview of current research on NPs with focus on currently less-investigated fields, such as the environmental fate in agroecosystems, migration in porous media, weathering, and toxic effects on plants. Expand
