TL;DR: In this article, a review collected scattered data and recent studies about the direct and indirect effects of coronavirus in the water cycle, and the direct impacts of COVID-19 on wastewater are related to the presence of the SARS-CoV-2 and suitable viral removal methods in different phases of treatment in wastewater treatment plants.
Abstract: The novel SARS-CoV-2 is expanding internationally. While the current focus is on limiting its transmission from direct contact with infected patients and surfaces during the pandemic, the secondary transmission potential via sewage should not be underestimated, especially in low-income and developing countries with weak wastewater treatment technologies. Recent studies have indicated SARS-CoV-2 positivity also be detected in the feces of patients. Therefore, the risk of transmission and infection can be increased into sewage by the fecal-oral way, mainly in some parts of the globe with a high amount of open defecation. This review collected scattered data and recent studies about the direct and indirect effects of coronavirus in the water cycle. The direct impacts of COVID-19 on wastewater are related to the presence of the coronavirus and suitable viral removal methods in different phases of treatment in wastewater treatment plants. The indirect effects of COVID-19 on wastewater are related to the overuse of cleaning and disinfecting products to protect against viral infection and the overuse of certain drugs to protect against virus or novel mental problems and panic to COVID-19 and consequently their presence in wastewater. This unexpected situation leads to changes in the quality of wastewater and brings adverse and harmful effects for the human, aquatic organisms, and the environment. Therefore, applying effective wastewater treatment technologies with low toxic by-products in wastewater treatment plants will be helpful to prevent the increasing occurrence of these extra contaminants in the environment.

TL;DR: In this paper, a review article collected scattered information and provided a future perspective on how worldwide COVID-19 disruption can perform as a catalyst to improve plastic and medical waste management.
Abstract: After December 2019, the globe was affected by a new coronavirus (SARS-CoV-2) that causes severe respiratory illnesses, which is responsible for increasing environmental problem consequences related to the extra consumption of medical waste and single-use plastics (such as personal protective equipment (PPE) and packaging plastics). Although the consumption of these plastics protects our life during this crisis, it is pivotal to move toward plastic recycling processes and environmentally friendly and sustainable alternatives, like bio-based degradable plastics with a circular economy perspective. This review article collected scattered information and provided a future perspective on how worldwide COVID-19 disruption can perform as a catalyst to improve plastic and medical waste management. Additionally, this paper illustrates the most effective disinfection technologies for COVID-19 wastes, such as high/low heat technologies and chemical disinfection, and PPE reusing processes, including dry heat, vaporized hydrogen peroxide, ozone, and UV light during the outbreak. In this vein, medical waste treatment facilities must be more automatic, with a minimum of personnel involved. Moreover, some recent valid guidelines from different international organizations and countries, future outlook, and practical recommendations that could be effective during this epidemic or even in the post-pandemic world for plastic and medical waste management were provided. Ultimately, governments should improve their waste management because of the potential of pathogen transmission or increased plastic and medical waste generation and try to enhance the environmental knowledge of society. People also should revise their viewpoints on plastic consumption by elevating sustainable behaviors, abandoning old habits, and adjusting to novel ones.

TL;DR: In this article, the issue of food recycling was comprehensively studied from the perspective of recent research, and the results of several investigations on the recycling of various food wastes, such as university waste, agricultural waste, food industry waste, and spent coffee ground (SCG) waste, were discussed in detail.
Abstract: In this review, the issue of food recycling was comprehensively studied from the perspective of recent research. Firstly, the concept of circular economy and its application in reducing waste production and the strategies for waste reduction (waste prevention) were discussed. The concept suggests that we can produce less waste from the beginning to reduce costs for recycling, instead of generating much waste for recycling through specific approaches. Secondly, the results of several investigations on the recycling of various food wastes, which have been less considered important parts of waste management, such as university waste, agricultural waste, food industry waste, and spent coffee ground (SCG) waste, were discussed in detail. Finally, various methods for recycling and sustaining food wastes (improving the rates of recycling) and their application in aforementioned sections were comprehensively presented.

TL;DR: In this article, most important sorption techniques used to remove long and short-chain PFASs are collected such as powdered or granular activated carbons, carbon nanotubes, biochar, polysaccharide-based adsorbents, ion exchange resins, and minerals.
Abstract: Per- and polyfluoroalkyl substances (PFASs) have highly complex behavior in the environment and are environmentally persistent. Exposure to PFASs causes cancer, liver toxicity, effect on the thyroid hormones, and also brings risks for the animal’s health. PFASs are separated into two categories: non-polymers and polymers, and most parts of the study of PFASs focus on non-polymers because they are more found in the environments. Urban water cycles such as drinking water, surface water, groundwater, and wastewater have been faced with the occurrence of PFASs, and PFOS and PFOA are the most detected PFASs. Various methods have been applied to remove PFASs which are divided into two main categories: separation and destruction. The PFASs destruction is still challenging in practice because of the powerful C–F bond and has only been utilized at the laboratory and small scale. Therefore, sorption is an eco-friendly and cost-effective technique with high efficacy that is commonly applied to eliminate PFASs from wastewater. In this review, most important sorption techniques used to remove long- and short-chain PFASs are collected such as powdered or granular activated carbons, carbon nanotubes, biochar, polysaccharide-based adsorbents, ion exchange resins, and minerals. Additionally, the possible mechanisms of PFASs sorption on various adsorbents are summarized, and different interactions such as electrostatic and hydrophobic interactions are reviewed. However, coexisting of inorganic anions and cations, natural organic matters, and other organic contaminants that generally exist in wastewater can affect the sorption of PFASs. Moreover, environmentally friendly and economical ways for the regeneration of adsorbents were summarized. Although this process needs more research and evaluation.

TL;DR: The advantages and disadvantages of COVID-19 on the environment including the quality of water, air, waste management, and energy consumption, as well as the impact of this pandemic on human psychology, the educational system, and the global economy are described.
Abstract: The end of the year 2019 was marked by the introduction of a third highly pathogenic coronavirus, after SARS-CoV (2003) and MERS-CoV (2012), in the human population which was officially declared a global pandemic by the World Health Organization (WHO) on March 11, 2020. Indeed, the pandemic of COVID-19 (Coronavirus Disease 19) has evolved at an unprecedented rate: after its emergence in Wuhan, the capital of the province of Hubei of the People's Republic of China, in December 2019, the total number of confirmed cases did not cease growing very quickly in the world. In this manuscript, we have provided an overview of the impact of COVID-19 on health, and we have proposed different nutrients suitable for infected patients to boost their immune systems. On the other hand, we have described the advantages and disadvantages of COVID-19 on the environment including the quality of water, air, waste management, and energy consumption, as well as the impact of this pandemic on human psychology, the educational system, and the global economy. In addition, we have tried to come up with some solutions to counter the negative repercussions of the pandemic.
