Plastics production (i.e 450 million tons per annum globally), use and disposal (i.e 300 million tons per annum globally) are one of the top environmental concerns and global waste management impediments. Nevertheless, nearly 90% of all plastics ever produced to present has never been recycled. Over the past decades, researchers’ voices have repeatedly been raised for acting and saving inland as well as aquatic ecosystems being harmed by the increasing plastic pollution. Microplastics have been reported by several studies to be in tap water, bottled drinks and in fish we eat. Consequently, conventions and agreements have been signed, laws and regulations enforced (banning, increased taxation, etc) in various regions and countries across the globe for lessening plastics harm on the environment. In this struggle, Rwanda looks to be in front line in beating plastic pollution crisis compared to other regional and continental countries; hence resulted in calling its capital Kigali by many, “the Africa’s cleanest city”. This success behind plastics break free could be attributed to Rwanda’s current strong institutional, political will (promotion of plastic recycling and reuse), legal frameworks (e.g non- biodegradable plastic bags ban, outlawing of single-use plastic items, penalties, severe fines, etc) and active citizens (e.g monthly community works also known as umuganda etc) in terms of eliminating plastic pollution, foster socio-economic development and environmental protection. These strategies do not only protect the environment but also save the money that the government would spend in cleaning the cities and facilitate the advertising of the country for its eco-friendliness; resulting in its tourism development. Recently, similar initiatives of reducing or banning plastics have been taken by several governments in African ,, lower-income countries and developed ones from other regions across the globe due to either limited recycling facilities, inadequate plastics trash disposal or as a solution to overcome the increase of plastic pollution which harm humans, farm animals, aquatic lives (fishes, sea turtles, etc), and the environment health. Thus, the present paper reviews the current knowledge of environmental impacts of plastics, approaches adopted for alleviating the harm from plastics in Rwanda and their implementation procedures which gave credits to the country on global environmental protection scene so that lessons from these practices can be implemented by other countries which aim at reducing plastics waste and associated pollution. The current solid waste management (i.e mainly plastics) and challenges are also discussed in order to be addressed by the authority in charge. Data and literature were retrieved from peer-reviewed journal articles, websites, books, reports, dissertations, local and international online newspapers. Despite significant efforts made towards a plastic free country, less has been written on plastic pollution in Rwanda; making it difficult to get reliable data and information for quantifying past impacts of plastic wastes. Furthermore, to the best of our knowledge no scientific research or report has been so far conducted to prove how plastic wastes contributed over the past years to flooding, prevented crops from growing, to what extent plastic litters have restrained rainwater from penetrating various soil types and other forms of plastic pollution in the country. Such studies are paramount for scientifically justify the ban initiatives in the country. This review resulted into encyclopedia that other researchers can build on to better understand environmental impacts of plastics to learn best plastics management practices for a sustainable environment.

Plastic usage in tourism activities has increased significantly in Vietnam over the past decades, leading to the burden of plastic pollution and the threat to sustainable tourism development. The Vietnamese government has recognized the importance of plastic waste management in sustainable tourism. Laws and regulations on controlling pollution due to non-biodegradable plastic bags. Public education activities have been organized to encourage people replace plastic products with natural materials, reuse plastic bags and reduce plastic wastes. Many tourism businesses have found ways to limit plastic consumption, such as replacing disposal plastic products with eco-friendly products. Vietnamese tourism has taken the first steps in reducing plastic waste pollution in tourism activities. This article proposed some solutions to limit and restrain plastic wastes from tourism in Vietnam.

Awareness surrounding plastic pollution has increased significantly in the past decade, leading to concerns on potential adverse effects on biota, including the consumption of microplastic by fish. Globally, plastic has been found in many species of fish, but little research has been undertaken in the southern hemisphere. We assessed the abundance and type of plastic in fish captured and sold for human consumption in Australia and Fiji. Fish (goatfish, sea mullet, paddletail, and common coral trout) had their gastrointestinal tracts dissected and microplastic quantified under a microscope. Plastic polymer types were confirmed using μ-FTIR. In Australia, plastic was found in 61.6% of fish gastrointestinal tracts, while in Fiji, 35.3% of fish had plastic. Fish from Australia had almost double the amount of plastic on average than fish caught in Fiji, with 1.58 (± 0.23) pieces per fish in Australia compared to 0.86 (± 0.14) in fish caught in Fiji. The types of plastic differed between countries, with fibers comprising 83.6% of microplastic pieces in fish from Australia whereas 50% of microplastic found in fish from Fiji was film. Polyolefin was the most abundant polymer type in both fibers from Australia and film from Fiji. We hypothesize variations in abundance and plastic type are a reflection of the population density and coastal geomorphology, but may also be a result of legislation and waste management strategies in the two countries. This work adds evidence to the pervasive presence of plastic in fish gastrointestinal tracts, reinforcing the urgent need for efficient plastic waste management, but also a better understanding of the impacts of microplastic on marine biota.

Rural areas are exposed to severe environmental pollution issues fed by industrial and agricultural activities combined with poor waste and sanitation management practices, struggling to achieve the United Nations’ Sustainable Development Goals (SDGs) in line with Agenda 2030. Rural communities are examined through a “dual approach” as both contributors and receivers of plastic pollution leakage into the natural environment (through the air–water–soil–biota nexus). Despite the emerging trend of plastic pollution research, in this paper, we identify few studies investigating rural communities. Therefore, proxy analysis of peer-reviewed literature is required to outline the significant gaps related to plastic pollution and plastic waste management issues in rural regions. This work focuses on key stages such as (i) plastic pollution effects on rural communities, (ii) plastic pollution generated by rural communities, (iii) the development of a rural waste management sector in low- and middle-income countries in line with the SDGs, and (iv) circular economy opportunities to reduce plastic pollution in rural areas. We conclude that rural communities must be involved in both future plastic pollution and circular economy research to help decision makers reduce environmental and public health threats, and to catalyze circular initiatives in rural areas around the world, including less developed communities.

Abstract Over the past three decades a growing awareness of environmental protection prompted the development of so-called green and sustainable technologies. Therefore, academic and wider community intensively explores new chemicals and safer, more energy efficient processes based on a rational compromise between economic, social, and environmental requirements. Due to low volatility and stability, ionic liquids emerged as a potential replacement for traditional volatile and harmful organic solvents. Various studies have been carried out to validate the green character of ionic liquids, whereby data published suggest that these compounds, due to their relatively high toxicity and poor biodegradability, could have an extremely negative impact on the environment. This paper presents the current knowledge on the toxicity of ionic liquids, with a special emphasis on the mechanisms by which this group of compounds causes changes in the morphology and physiology of organisms at different organisational levels of the ecosystem.

Plastic pollution has become a major global environmental problem. The amount of plastic waste, including microplastics discharged into the environment, is on the increase, causing harm to the environment, ecosystems, especially marine ecosystems, entering the food chain, and affecting human health. Recognizing the environmental risks of plastic waste, the State has issued many legal documents on plastic waste management such as the Law on Environmental Protection (2014, 2020); Law on Environmental Protection Tax 2010; National environmental protection strategy up to 2020, Vision 2030; National strategy on integrated solid waste management up to 2025, Vision 2050, among others. However, there are still many shortcomings to plastic waste management in Vietnam, e.g. there are no effective solutions in reducing, sorting, collecting, reusing, recycling and treating waste. More importantly, public awareness and understanding of microplastic pollution in Vietnam still need improving. Therefore, pollution caused by microplastics needs to be studied and evaluated in relation to its origin, current situation, impacts and management policies.

The accumulation of plastic wastes in different environments has become a topic of major concern over the past decades; therefore, technologies and strategies aimed at mitigating the environmental impacts of petroleum products have gained worldwide relevance. In this scenario, the production of bioplastics mainly from polysaccharides such as starch is a growing strategy and a field of intense research. The use of plasticizers, the preparation of blends, and the reinforcement of bioplastics with lignocellulosic components have shown promising and environmentally safe alternatives for overcoming the limitations of bioplastics, mainly due to the availability, biodegradability, and biocompatibility of such resources. This review addresses the production of bioplastics composed of polysaccharides from plant biomass and its advantages and disadvantages.

Over the past years, several efforts were undertaken in an attempt to improve solid waste management in Lebanon. However, with the lack of a well-established national plan and defined policies and legislation, all attempts achieved little or no progress. Several challenges continue to hinder the sector's successful development at various levels: politically, legally and institutionally, socially, land use, and last but not least, technically. This chapter provides an overview of waste management practices in Lebanon such as waste generation, waste composition, current status of waste management practices, policy, and legislation, while highlighting the main challenges for implementing an integrated solid waste management towards a sustainable system.

Today, a large amount of solid waste is generated worldwide, of which only 10% is reused. The amount of solid waste reused is reduced if the waste has some characteristics that make it hazardous, as is the case of hospital solid waste (HSW). To this are added the environmental impacts that the waste and its inadequate handling entails. This research shows the association of solid waste management practices with environmental impacts in the Alberto Sabogal Sologuren National Hospital. For this, segregation, internal transport of solid waste, cleaning and disinfection of the equipment and the availability of personal protective equipment were taken into account. To achieve this, an evaluation of its management was carried out, which was carried out by visiting each of the services and / or environments of the Hospital, a physical characterization of solid waste for seven days where solid waste was identified and quantified. areas and services, an interview with staff working in the hospital center and an identification of environmental factors that are impacted as a result of waste management practices.
