“…Macroscopic plastic debris has also been evidenced to directly block photosynthesis and entangle plant seedlings, having a considerable impact in plant survivability in ecosystems deeply affected by littering [ 69 ]. Soil can also preserve plastic through earth-borne biota, such as earthworms, which are reported to burrow plastic particles that hinder solar-dependent degradation through UV radiation and lead to slow plastic decomposition [ 70 ].…”

Plastics have become an essential part of the modern world thanks to their appealing physical and chemical properties as well as their low production cost. The most common type of polymers used for plastic account for 90% of the total production and are made from petroleum-based nonrenewable resources. Concerns over the sustainability of the current production model and the environmental implications of traditional plastics have fueled the demand for greener formulations and alternatives. In the last decade, new plastics manufactured from renewable sources and biological processes have emerged from research and have been established as a commercially viable solution with less adverse effects. Nevertheless, economic and legislative challenges for biobased plastics hinder their widespread implementation. This review summarizes the history of plastics over the last century, including the most relevant bioplastics and production methods, the environmental impact and mitigation of the adverse effects of conventional and emerging plastics, and the regulatory landscape that renewable and recyclable bioplastics face to reach a sustainable future.

Повсеместное использование пластмассы привело к увеличению количества пластикового мусора, накапливающегося в окружающей среде и разрушающегося на мелкие фрагменты, в том числе размером <5 мм – микропластик. За последнее десятилетие все большее количество исследований посвящается потенциальной опасности и методам анализа пластиковых частиц в водной среде. Однако, почвы могут быть загрязнены намного сильнее, при этом мало известно о накоплении микропластика в почве, возможных источниках, последствиях, взаимодействии пластиковых частиц с почвенными организмами и эффективных методах анализа. В данной статье представлен обзор, направленный на представление имеющейся информации о потенциальном экологическом воздействии микрочастиц пластика, возможных источниках и путях попадания в почвы, а также о предлагаемых методах аналитического контроля данного загрязнителя. Обзор позволяет наметить основные методологические проблемы, задачи и перспективы исследований в данной области. The ubiquitous use of plastics has led to an increase in the amount of plastic debris that accumulates in the environment and breaks down into small fragments, including <5 mm microplastics. Over the past decade, an increasing amount of research has focused on the potential hazards and methods for analyzing plastic particles in the aquatic environment. However, soils can be much more heavily contaminated, and little is known about the accumulation of microplastics in soil, possible sources, consequences, interactions of plastic particles with soil organisms, and effective methods of analysis. This article provides an overview aimed at presenting the available information on the potential environmental impacts of microplastics, possible sources and routes of entry into soils, and proposed methods for the analytical control of this pollutant. The review allows to outline the main methodological problems, tasks and prospects for research in this area.

“…Microplastics (i.e., <5 mm) represent a new substrate for distinct microbial colonization and biofilm formation, called the “Plastisphere” ( Zettler et al, 2013 ; McCormick et al, 2014 ), suggesting that many of these organisms are able to degrade the material. Biodegradation effects on ubiquitous polyolefins such as polyethylene (PE) and polystyrene (PS), may be exerted, in fact, by bacteria, and fungi (or associated enzymes) isolated from the open environment and from the guts of insects ( Yang et al, 2015a , b ; Bombelli et al, 2017 ; Brandon et al, 2018 ; Wang et al, 2020 ; Woo et al, 2020 ) and other animals ( Leonov and Tiunov, 2020 ; Song et al, 2020 ). Concerning insect gut microbiota, a few studies showed evidence of plastic biodegradation mostly by bacteria associated with coleopteran and moth species.…”

Plastic production has been increasing exponentially in the last 60 years, but plastic disposal is out of control, resulting in the pollution of all ecosystems on Earth. Finding alternative environmentally sustainable choices, such as biodegradation by insects and their associated gut microbiota, is crucial, however we have only begun to characterize these ecosystems. Some bacteria and one fungus have been previously identified in the gut of Greater Wax Moth larvae (Galleria mellonella L., Lepidoptera, Pyralidae) located mainly in the Northern hemisphere. The aim of this study was to describe changes in the gut microbiota associated with the consumption of polyethylene and polystyrene by the Greater Wax Moth in Argentina, considering both bacteria and fungi. Larvae were fed polyethylene, polystyrene and beeswax as control for 7 days. Next generation sequencing revealed changes in the bacterial gut microbiome of the wax moth larvae at the phyla and genus levels, with an increase in two Pseudomonas strains. The fungal communities showed no differences in composition between diets, only changing in relative abundance. This is the first report of both bacterial and fungal communities associated with a plastivore insect. The results are promising and call for more studies concerning a potential multi-kingdom synergy in the plastic biodegradation process.
