About this deal

Finally, we advocate for an all-encompassing model that includes the terrestrial and freshwater environment. This can be achieved by coupling the Plastic Pathfinder with a river plastic transport model, for example with the model developed by Newbould et al. (2021). The river entry points predicted by the Plastic Pathfinder will form this link as they deliver information on where, when and how much plastic waste leaks from land into the river system. This will allow for genuine estimates on how much of the generated land-based plastic waste actually reaches the oceans via rivers. 4.2 The Plastic Pathfinder – an innovative tool During core surgical training, candidates should build up evidence of their interest and experience in plastic surgery. This can be done by carrying out audits, presenting and publishing within plastic surgery. Training courses such as Advanced Trauma Life Support (ATLS) and Basic Surgical Skills and Care of the Critically Ill Surgical Patient (CCrISP) completion will also boost candidate’s application for ST3 posts (1).

Plastic pollution is the accumulation of plastic objects and particles (e.g. plastic bottles, bags and microbeads) in the Earth's environment that adversely affects humans, wildlife and their habitat. [1] [2] Plastics that act as pollutants are categorized by size into micro-, meso-, or macro debris. [3] Plastics are inexpensive and durable, making them very adaptable for different uses; as a result, manufacturers choose to use plastic over other materials. [4] However, the chemical structure of most plastics renders them resistant to many natural processes of degradation and as a result they are slow to degrade. [5] Together, these two factors allow large volumes of plastic to enter the environment as mismanaged waste which persists in the ecosystem and travels throughout food webs. [6] [7] Despite global efforts to reduce the generation of plastic waste, losses to the environment are predicted to increase. Modelling indicates that, without major interventions, between 23 and 37 million tonnes per year of plastic waste could enter the oceans by 2040 and between 155 and 265 million tonnes per year could be discharged into the environment by 2060. Under a business as usual scenario, such increases would likely be attributable to a continuing rise in production of plastic products, driven by consumer demand, accompanied by insufficient improvements in waste management. As the plastic waste released into the environment already has a significant impact on ecosystems, an increase of this magnitude could have dramatic consequences. [34] Effect on flooding Volunteers clearing gutters in Ilorin, Nigeria during a volunteer sanitation day. Even when there is adequate infrastructure for sanitation, plastic pollution can prevent drainage and impede sewage flow. Plastic surgery is still a relatively small specialty. However, the number of consultant posts has doubled in the last twenty years and it has become an integral part of hospital practice. As of 2019, 368 million tonnes of plastic is produced each year; 51% in Asia, where China is the world's largest producer. [13] From the 1950s up to 2018, an estimated 6.3 billion tonnes of plastic has been produced worldwide, of which an estimated 9% has been recycled and another 12% has been incinerated. [14] This large amount of plastic waste enters the environment and causes problems throughout the ecosystem; for example, studies suggest that the bodies of 90% of seabirds contain plastic debris. [15] [16] In some areas there have been significant efforts to reduce the prominence of free range plastic pollution, through reducing plastic consumption, litter cleanup, and promoting plastic recycling.

The increased circularity of plastics pathway

This ratio is the highest of all the medical and surgical specialities. It is followed by trauma and orthopaedic surgery that sits at 1.40 and then neurosurgery at 1.00 (7). Trainees can opt to complete a fellowship post speciality training completion and prior to applying to a consultant post. (5) Note: The life cycle steps highlighted in green are the ones most relevant for the increased circularity of plastics pathway, but are not necessarily the only ones that can be found.

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 generationThe United States is the world leader in generating plastic waste, producing an annual 42 million metric tons of plastic waste. [57] [58] Per capita generation of plastic waste in the United States is higher than in any other country, with the average American producing 130.09 kilograms of plastic waste per year. Other high-income countries, such as those of the EU-28 (annual per capita generation 58.56kg), also have a high per capita plastic waste generation rate. Some high-income countries, such as Japan (annual per capital generation 38.44kg), produce far less plastic waste per capita. [59] [60] Plastic pollution 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. Plants are important for the environment and ecosystems so the plastics are damaging to plants and organisms living in these ecosystems. [96] Non-degradable biobased plastics are conventional plastic types produced with renewable biobased materials. This type of plastic can be recycled in the same way as and mixed with plastics from fossil fuel sources. Limited funding, some trainees will need to pay for additional education courses themselves, which can be costly Mismanaged plastic waste leads to plastic directly or indirectly entering terrestrial ecosystems. [95] There has been a significant increase of microplastic pollution due to the poor handling and disposal of plastic materials. [96] In particular, plastic pollution in the form of microplastics now can be found extensively in soil. It enters the soil by settling on the surface and eventually making its way into subsoils. [97] These microplastics find their way into plants and animals. [98]

Access-based circular business models enable consumers to access goods and services that meet their needs without requiring them to own the product itself. These business models have the potential to reduce the production of new products, while increasing the intensity and efficiency of existing products through shared use and reuse.

There is a mix between inpatient and outpatient load. This will depend largely on subspecialty and areas of interest. Depending on the complexity of surgery, some patients will have long term follow ups allowing for continuity of care (1).Microdebris are plastic pieces between 2mm and 5mm in size. [37] Plastic debris that starts off as meso- or macrodebris can become microdebris through degradation and collisions that break it down into smaller pieces. [3] Microdebris is more commonly referred to as nurdles. [3] Nurdles are recycled to make new plastic items, but they easily end up released into the environment during production because of their small size. They often end up in ocean waters through rivers and streams. [3] Microdebris that come from cleaning and cosmetic products are also referred to as scrubbers. Because microdebris and scrubbers are so small in size, filter-feeding organisms often consume them. [3] More information can be found in the EEA’s briefing ‘ Biodegradable and compostable plastics — challenges and opportunities’ and in the European Commission’s communication on biobased, biodegradable and compostable plastics.

The Plastic Pathfinder works with so called MPW clusters, whereby a single MPW cluster consists of all the MPW that was generated in a single grid cell during a single time step. Once MPW is released from its land-based source, it is available for transport. MPW generally consist of different types of plastic waste (e.g., plastic bottles, bags, food wrappers), which are likely to have different mobilisation and transport thresholds. However, the mobilisation and transport thresholds of different types of plastics over land has not been studied up to date. Due to this knowledge gap we were forced to assume uniform mobilisation and transport thresholds that hold for all types of macroplastic waste. This means that the current version of the Plastic Pathfinder simulates the transport and accumulation of a representative subset of macroplastic waste, which is expected not to reflect the transport behaviour of all types of macroplastic waste. As soon as plastic type specific mobilisation and transport thresholds become available, they can replace the uniform thresholds. For each modelled time step during which the wind or surface runoff exceeds their respective threshold, transport is simulated and the entire MPW cluster is displaced from its current grid cell to an adjacent one. When different MPW clusters are transported towards the same grid cell, or when a new MPW cluster is generated in a (land) grid cell in which another MPW cluster was already present, the mass of all those MPW clusters are added. In this way MPW clusters can ‘expand’. The land use input defines for each grid cell the type of land use. Land use data can be extracted from a database such as the ESA CCI Land Cover time-series ( Land Cover CCI Product User Guide Version 2.0, 2017). The Plastic Pathfinder distinguishes between water and five types of land use:Developing a roadmap for Plastics Europe and its members to accelerate the industry’s transition towards 2050. This will include interim milestones/targets and more ambitious policy recommendations, and the development of mechanisms designed to support and incentivise the industry. This roadmap will report/review the targets being set by its members and the progress being made.
