Abstract:
Abstract The World Ocean pollution with production and consumption waste is one of the hottest global environmental problems of today. The term “marine litter” has already become firmly established in the scientific use, and in both Russian and world research literature it is defined as any manufactured or processed material, directly or indirectly, intentionally or unintentionally left in the marine environment. It is plastics and its elements that account for a considerable share of marine litter. Research on the pollution of the beaches of Primorsky Krai. with marine litter been carried out

Abstract. Coastlines potentially harbor a large part of litter entering the oceans, such as plastic waste. The relative importance of the physical processes that influence the beaching of litter is still relatively unknown. Here, we investigate the beaching of litter by analyzing a data set of litter gathered along the Dutch North Sea coast during extensive beach cleanup efforts between the years 2014 and 2019. This data set is unique in the sense that data are gathered consistently over various years by many volunteers (a total of 14 000) on beaches that are quite similar in substrate (sandy)

Abstract:
Plastics, one type of marine debris, account for nearly 90% of beach cleanup litter collected (Surfrider Foundation, 2022), with 22 million pounds (10 million kilograms) entering the Great Lakes annually, half going into Lake Erie (Hoffman and Hittinger, 2017). Lake Erie provides drinking water for 12 million people and supports a $12.9 billion coastal tourism industry (USEPA, 2022). Plastic is hazardous to aquatic life through entanglement, ingestion, and associated contaminants (Derraik, 2002), and negatively impacts Ohio’s economy (NOAA Marine Debris Program, 2019).

AbstractIt is well known that approximately 90% of all marine debris consists of reusable plastics. Small plastic particles are easily swallowed and disturb marine ecosystems. However, cleaning up marine debris is difficult because of its economic feasibility. Though there are many proven land-based recycling processes available, the high costs of gathering marine debris and transporting it adds to marine debris-related problems. Marine debris cleanup is challenging despite various studies that point to its importance. Therefore, we discuss a recycling chain that concerns gathering, transporti

The problem of marine plastic litter is an issue of great concern, because of the long time needed for its complete decomposition, from ten to several thousand years, and the impacts on marine ecosystems and human health (Lebreton and Andrady, 2019, Soares et al. 2020). In Europe, about 500.000 tons of plastic litter are released into the sea every year (Interreg Europe, 2021), most of which is produced inland by agricultural, industrial and urban activities, and then transported by rivers towards the sea (Lebreton and Andrady, 2019).

Microplastics are the biggest pollutants in marine ecosystems. Each year, over 8 million tons of plastic enter the oceans. Via microbes, microplastics may transport toxic chemicals into food webs. It is therefore important to create a way to remove microplastics and reduce the impact of microplastics on the ocean’s food web. This paper discusses the plan of using kiln firing, laser firing, pollution control, and green energy production to reuse marine plastics. We used a wood-fired kiln to design a kiln boat.

Litter on beaches and in the water includes a lot of things—plastic bags, straws, bottles, plastic utensils, toys, all of which fragment into smaller pieces. Marine animals, including mammals, birds, and turtles, mistake it for food and may eat large amounts, resulting in injury and in some cases death. Plastics include a large variety of toxic chemicals in them. Animals may also get entangled in the ropes (made of plastic these days) of fish or lobster traps and drown or drag it around and eve
