The surface runoff input provides for each time step for a given grid cell the flux of surface runoff in millimetres per day. Surface runoff data can directly be extracted from a database such as GRUN ( Ghiggi et al., 2019) or computed from rainfall data using a surface runoff coefficient. The runoff coefficient (the ratio between runoff and rainfall) is the fraction of the rainwater that does not infiltrate in the soil and can transport plastics along the surface. The type of land cover (i.e., vegetation) plays a major role in this process. The surface runoff direction in each grid cell is equal to the direction of the steepest terrain slope of that grid cell ( Figure 3B). The rainfall data used for our model application ( Supplementary Figure S2), are based on the frequency of actual amounts of rainfall measured between 1981 and 2000 at the De Bilt weather station, the Netherlands (frequency tables are available at the KNMI Data Platform ( dataplatform.knmi.nl, 2000), the frequency table used for the rainfall is provided in Supplementary Table S5). We used typical runoff coefficients to convert the rainfall values into surface runoff values ( Goel, 2011; Karamage et al., 2017) ( Supplementary Table S6). For our model application we assumed no time lag between a rainfall event and the generation of surface runoff. In some environments, for example in mountainous areas, a time lag between precipitation (e.g. snow) and subsequent generation of surface runoff (e.g. snow melt) is expected. In that case we recommend coupling the Plastic Pathfinder to a hydrodynamic model that takes such time lags between rainfall and the generation of surface runoff into account. 2.5.5 Mismanaged plastic waste generation Marine plastic pollution is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean. Eighty percent of marine debris is plastic. [100] [101] Microplastics and nanoplastics result from the breakdown or photodegradation of plastic waste in surface waters, rivers or oceans. Recently, scientists have uncovered nanoplastics in heavy snow, more specifically about 3,000 tons that cover Switzerland yearly. [102]

Good practice examples for the increased circularity pathway are often related to the increased collection, sorting and recycling of plastics achieved through business, policymaker and citizen initiatives. These are discussed below. Increased collection and sorting of plastic In 2019 a new report "Plastic and Climate" was published. According to the report, in 2019, production and incineration of plastic will contribute greenhouse gases in the equivalent of 850 million tonnes of carbon dioxide (CO 2) to the atmosphere. In current trend, annual emissions from these sources will grow to 1.34 billion tonnes by 2030. By 2050 plastic could emit 56 billion tonnes of greenhouse gas emissions, as much as 14 percent of the earth's remaining carbon budget. [79] By 2100 it will emit 260 billion tonnes, more than half of the carbon budget. Those are emission from production, transportation, incineration, but there are also releases of methane and effects on phytoplankton. [80] Effects of plastic on land Increasing the circularity of plastics and closing the materials loop, including through higher resource efficiency and lower material (and value) losses, are important for maintaining the value and utility of plastics. A major issue is the (quantity and) quality of recycled materials on the market at present, as only a fraction of these recyclates can be used in high-value products. Therefore, most of the recycled materials are part of downcycling processes.Chrisafis, A., 2022, ‘Ban on single-use restaurant tableware hailed as fast-food “revolution” in France’, The Guardian, 28 December 2022 ( https://www.theguardian.com/world/2022/dec/28/france-ban-on-single-use-restaurant-tableware-hailed-as-fast-food-revolution) accessed 1 February 2023.

Alongside its scientific significance, the Plastic Pathfinder has a societal relevance as well, as it can provide guidance on the prioritisation of plastic pollution prevention, mitigation and reduction strategies. By knowing when and where plastics on land accumulate and which transport routes they take, targeted clean-up and entrapment strategies can be developed. The removal of plastics from the natural environment is a matter of great urgency, because plastic waste poses serious threats to species health and human livelihood in general ( van Emmerik and Schwarz, 2019; Windsor et al., 2019; Bucci et al., 2020; Everaert et al., 2020). Data availability statementPlastic surgery is rewarding as procedures have the capacity to drastically improve a patient's quality of life. Qualities required include visuospatial awareness, hand-eye coordination, leadership skills, stamina to cope with the role and communication skills. Personal emotional resilience is required due the exposure to patients who have undergone severe trauma and disfigurement. Global plastic production has surged from 1.5 million tons in the 1950s to 335 million tons in 2016, resulting in environmental concerns. A significant issue arises from the inefficient treatment of 79% of plastic products, leading to their release into landfills or natural environments. [10]

EC, 2022, Communication from the Commission to the European Parliament, the Council, the European Economic and Social Committee and the Committee of the Regions — EU policy framework on biobased, biodegradable and compostable plastics (COM(2022) 682). Policymakers can affect the speed of development of the smarter use pathway, the increased circularity pathway and the renewable material pathway by providing timely and proper policy frameworks and clarity. EU policy makers can continuously develop and ensure the implementation of policies that increase the circularity and sustainability of plastics production and consumption. The UN global treaty on plastics currently being developed will hopefully contribute to making plastics more sustainable and circular globally.Helping you to create pristine pathways and functional gravel spaces, our CORE PATH gravel stabilisation grid is an advanced solution that’s easy to install and maintain.
