As a global environmental problem, plastic pollution has attracted worldwide attention. Plastic wastes not only disrupt ecosystems and biodiversity, but they also threaten human life and health. Countries around the world have enacted regulations in recent years to limit the use of plastics. Paper products have been proposed as promising substitutes for plastics, which undoubtedly brings unprecedented opportunities to the pulp and paper industry. However, paper products have some deficiencies in replacing certain plastic products. Research and development to improve paper properties and reduce production costs is needed to meet such challenges.

In today’s society, consumers’ food needs can be satisfied by catering e-commerce platforms. However, the plastic pollution of tableware and packaging caused by a large number of catering orders every day has always been an unsolved environmental problem. (1) Background: At present, China’s three largest catering platforms, Meituan, Eleme and Baidu, receive 20 million takeout orders daily and consume about 60 million plastic products. Plastic pollution will have a sustained impact on the environment. (2) Methods: In this study, we use literature research and case analysis. We use Meituan’s takeout food as an example. We studied the takeout business growth, status of online takeout in the treatment of plastic packaging, harm to environment, humans and animals, as well as specific solutions. (3) Results: There are four main reasons which contribute to the plastic packaging pollution (i.e., high recycling cost, difficulty to deal with mixed plastic packaging, low effectiveness of collecting plastic packing, and immature technology and treatment to incinerate and landfill catering plastic waste). (4) Conclusion: Our findings suggest that regulators, takeout platforms and consumers, which have corresponding responsibilities in the environmental protection consumption of online food, are supposed to work together to get rid of the online takeout pollution for achieving sustainable consumption. Not only is government legislation needed to improve the waste management system and encourage the exploration of new intelligent waste classification tools, but platforms, businesses and users should enhance the environmental awareness of online takeout packaging pollution as well. Theoretical contributions and managerial implications are also discussed.

Plastic pollution is an increasing environmental problem, but a comprehensive understanding of its effect in the environment is still missing. The wide variety of size, shape, and polymer composition of plastics impedes an adequate risk assessment. We investigated the effect of differently sized polystyrene beads (1-, 3-, 6-µm; PS) and polyamide fragments (5–25 µm, PA) and non-plastics items such as silica beads (3-µm, SiO2) on the population growth, reproduction (egg ratio), and survival of two common aquatic micro invertebrates: the rotifer species Brachionus calyciflorus and Brachionus fernandoi. The MPs were combined with food quantity, limiting and saturating food concentration, and with food of different quality. We found variable fitness responses with a significant effect of 3-µm PS on the population growth rate in both rotifer species with respect to food quantity. An interaction between the food quality and the MPs treatments was found in the reproduction of B. calyciflorus. PA and SiO2 beads had no effect on fitness response. This study provides further evidence of the indirect effect of MPs in planktonic rotifers and the importance of testing different environmental conditions that could influence the effect of MPs.

This article examines the depiction of the environmental problem of overpopulation in the two Marvel films Avengers: Infinity War and Avengers: Endgame through the analysis of the character Thanos and his Malthusian theory and his cornucopian thinking counterpart, The Avengers. The article investigates how these two theories affect and form the subject of overpopulation in the two films and what signal the films send in relation to environmental alternatives. It suggests that the films hinder the contemplation of all environmental alternatives through their depiction of the Malthusian alternative as a villainous and unwarranted ideology.

This article discusses issues related to the environmental problems in various sectors of the Central Kazakhstan’s economy at the present stage. It is emphasized that the level of environmental pollution is increasing along with industrial progress in coal, non-ferrous and ferrous metallurgy, chemistry, engineering, and the growth of the transport highways network and numerous communications. The authors of the article give examples of how the transition to market mechanisms of economic development generated, on the one hand, the growth of the republic’s powerful economic potential. On the other hand, the increase in industrial production with energy and resource-intensive production has led to a real threat of an environmental crisis in the region. It is concluded that the solution of the environmental problem is possible by preserving and restoring natural systems, a complete social transition to sustainable development by practical implementation of the environmental concept, including natural-resource, techno-economic, demographic and sociocultural aspects. According to the authors, these measures will contribute to the way out of the current environmental crisis, a radical improvement of the environment, will be the key to preserving the ecology of space. The methodological basis of the study was the principle of scientific objectivity, which allowed to analyze the subject under study taking into account the realities of economic changes in the industry.

Тhe article is devoted to the global environmental problem of plastic waste pollution. Now, about 9 billion tons of primary plastic have been produced. Of this amount, 6.3 billion tons is plastic waste, of which 9 % was recycled, 12 % incinerated, and 79 % accumulated in landfills or in the environment. The main feature of plastic materials is their stability. Once in the environment as waste, plastic can be in its original state for more than 450 years. The purpose of the article is to study the current state of production and use of plastics, as well as the field of plastic waste management; identification of perspective methods for solving the problem of plastic pollution. Plastics are organic macromolecular compounds that have high quality characteristics. Due to this, they became widespread. There are different types of plastics: thermoplastics, thermosets, foams and bioplastics. Currently, 40% of plastic is used once, after which it is discarded. Under the influence of various factors in the environment plastic slowly breaks down into small fragments, known as microplastics. Microplastic particles get into the soil, water, and through food chains can enter the human body. Potentially microplastics can negatively affect the human body. To solve the problem of accumulation of plastic waste in the environment, many countries around the world, including Ukraine, are implementing a waste management system based on the European waste management hierarchy. The hierarchy reflects five approaches to waste management: Removal (waste disposal and incineration without energy production), Recovery (waste incineration with energy production), Recycling (waste conversion into secondary raw materials for reuse), Reuse (waste reuse without recycling) and Prevention (waste amount minimization). Disposal is the least efficient way of waste management, and recycling and prevention are the most effective ways. Keywords: plastic, waste, pollution, environment, landfill, recycling.
