Plastics are novel entities that have exceeded the planetary safe operating space due to extensive and resource-intensive production, uncontrolled environmental releases, and failure to control the chemicals within the materials. This paper examines evidence and discusses how plastics pollution affects Earth-system processes along the impact pathway from production, to release, to environmental fate and impacts of plastics and their additives. Multiple lines of evidence are necessary to capture the complex reality of these substances and attempts to quantify a singular boundary would be detrimental to the global governance of plastics. We demonstrate causal links between plastics and other major environmental problems at the global scale, exacerbating the consequences of breaching other planetary boundaries, especially climate change and biodiversity loss. We propose ways to translate these assessments into control variables for the globally and biophysically defined planetary boundaries framework that can be utilized to tackle plastics pollution. Efforts should be oriented towards further developing and monitoring a set of control variables that describe the actual state of the system along the impact pathway. We call for experts and policymakers to take urgent action, considering plastics pollution not only as a waste management problem but as an integrative part of climate change, biodiversity and natural resource use policy.

“…Second, Cañado et al. (2022) focus on the circularity potential of marine plastic waste, by recuperating this waste to be used in 3D printing for new products in the marine industry. For this, they conduct an LCA study in which they compare marine plastic waste debris recuperation with virgin polymers (e.g., bio‐based polyamide, polylactic acid, or polyhydroxybutyrate).…”

Human interaction with ocean resources has historically been challenging due to the difficulties that arise when a terrestrial species aims at becoming successful in a marine environment. Shipwrecks, for instance, have doomed coastal communities for centuries, and even today fishing is one of the deadliest sectors in the labor force. Similarly, human-induced marine environmental catastrophes, such as oil spills for instance (Trevors & Saier, 2010), have commonly been laborious to clean up due to the inherent difficulty of humans performing beyond terrestrial ecosystems.Continued human population and economic growth since the beginning of the Industrial Revolution have exacerbated the need of human societies for mineral ores, fossil fuels, and other sources of energy, water, and food. This has led to the occupation of vast areas of terrestrial land, to the extent that humans now have a noticeable footprint in all the world's terrestrial biomes. In the world's oceans this same pattern has occurred at a slower pace throughout the decades, with fishing activities becoming more efficient with the arrival of steam vessels in the 1880s, diesel in the 20th century (Engelhard, 2008), and the incorporation of sophisticated detection systems turning ancestral coastal fishing activities into highly industrialized systems that land millions of metric tons of fish and other marine species annually (Fornshell & Tesei, 2013). Similarly, oil rigs spread quickly in the world's ocean to provide additional fossil fuel supplies for thirsty growing economies (Nyman, 2015), marine fright soared with the process of globalization (Mersin et al., 2019) with thousands of cargo vessels swarming the seas and, more recently, seabed mining has appeared in the public and private agenda as an alternative and lucrative sector to maintain the supply of metal ores in the technosphere (Levin et al., 2020). This increased pressure of human activities on the ocean and its resources has translated into a series of environmental impacts that have affected marine conservation (Knowlton, 2021) and degraded vast areas of the ocean.

Packaging represents a significant source of all polymer waste produced in the world. Thus, improving recycling methods is essential to achieve an environmentally sustainable condition since the volume of produced polymer and of related waste has grown. Expanded polystyrene (EPS) foam is a thermoplastic with important performance of properties such as thermal isolation and absorption of mechanical energy that allow large application in packaging and other segments. However, the EPS recycling is a challenger due to its low density and poor properties. The rubber incorporation to the recycled EPS is an alternative for the toughening of the polymer matrix as well as improving its mechanical properties. In present study, EPS waste from electric and electronic products packaging was treated by three distinct methods for polymer densification and after it was thermo‐mechanically processed by extrusion with variable content of ground tire rubber (GTR) and compatibilizer agent styrene‐butadiene‐styrene (SBS) copolymer to produce compatibilized and toughened PS/rubber blends. Mechanical, thermal and rheological properties of materials were evaluated by different analyses. The incorporation of rubber to the recycled EPS has significantly improved the mechanical properties of the material and the presence of the SBS agent was effective to compatibilize the PS/rubber blends. Therefore, the preparation of compatibilized PS/rubber blends showed to be a way to the mechanical recycling of EPS and rubber tires waste.
