Disposable Plastic

The increased use of disposable plastic consumer packaging, especially in the sanitary and epidemiological conditions of COVID-19, makes it necessary to dispose of the resulting waste. The problem is aggravated by the weak processing of waste, which is stored and not destroyed in nature. In this regard, the purpose of the article is to analyze the problems caused by the consumption and disposal of plastic disposable plastic packaging by retail chains and public catering companies. A brief comparative analysis of the composition and quantities of the plastic waste was carried out. The legal documents governing the waste management in Russia and abroad were studied. The Russian waste recycling market was compared with the foreign ones. Data on polymeric waste(composition, quantity, share in the total mass of waste, cost, and possibility of using as a secondary raw material) were studied. The lack of an effective system for collecting polymer waste and its utilization in Russia was emphasized and compared with Asian, European and American countries. In these countries, there are regulatory documents governing the collection and recycling of plastic products; the production itself is economically attractive. Recommendations aimed to encourage manufacturers to recycle waste were given; options for solving the problem of recycling plastic waste on a legislative, economic and managerial basis were offered.

Comprehensive Study

The results of a comprehensive study of the process of thermal destruction of household waste and industrial polymeric materials in a mixture with petroleum feedstock at a pilot coking unit are presented. A mixture containing polyethylene, polypropylene, polystyrene and polyethylene terephthalate was used as household polymeric waste. Industrial waste was represented by a mixture of polyethylene and polypropylene. The qualitative and quantitative composition of the resulting products was investigated. It is shown that the involvement of polymer waste in an amount of up to 8% by weight in the raw material of the coking plant will make it possible to efficiently process polymer waste without changing the technological regime and quality of the products obtained. It has been established that the impurities of inorganic components present in the polymer raw material do not affect the coking process.

The results of studies on the thermal processing of synthetic multi-tonnage polymeric waste (polypropylene, polycarbonate, textolite, PET, organoplastics and tire rubber) with the production of carbon sorbents for technological and environmental purposes are presented. The influence of the nature of the activating agent and the conditions of the process with the production of sorbents with predetermined properties was studied. Analysis of the research results allowed us to establish that the main factors affecting the yield of carbonizate and the formation of a porous structure of carbon sorbents from synthetic polymer waste are the degree of aromaticity and the location of benzene rings in the polymer structure, the proportion of oxygen in the precursor. The criteria for selecting synthetic polymer wastes as raw materials for obtaining carbon sorbents with predetermined properties are established. The results of the research can be used in the development of technologies for obtaining carbon sorbents with predetermined properties from waste synthetic polymers and the selection of technological parameters for processes.

Bearing in mind that only 42% of plastic packaging post-consumer waste is recycled in Europe, the European Directive 2018/852 established the key target of a 55% plastic packaging waste recycling rate by 2030. For this reason, PlastiCircle, funded by the European Union’s Horizon 2020 research and innovation program project, aims to foster the recycling of packaging, improve all stages of the waste collection, and promote responsible consumption. Three European cities have been selected as locations for pilot implementation: Valencia (Spain), Utrecht (The Netherlands) and Alba Iulia (Romania). The main objective of the present study has been to evaluate the participants’ opinion and attitudes on plastic recycling. This paper presents the results from the district of San Marcelino in the city of Valencia, the first PlastiCircle pilot to face the challenges of encouraging households to participate more in plastic waste sorting and recycling.

Several researches and technologies on polymer recycling have been driven and justified by the uncontrolled and crescent polymer waste generation in the world. Herein, a critical and concise review on the recent and well-established recycling practices for polymer waste is presented, taking into account not only thermoplastics (or plastics) but also thermosets and elastomers. Moreover, sorting and characterization techniques for polymer waste recycling are detailed and their importance is discussed. An in-depth analysis of the literature indicated that novel and advanced recycling methods for polymeric waste (PW) present difficulties to be applied in the industrial sector, mainly the scientific innovations in the chemical recycling area. In the current scenario, new challenges for the recycling sector are linked to highly contaminated PW from electrical, electronic, and medical products.

Polymeric Waste

In modern society, it is impossible to imagine life without polymeric materials. However, managing the waste composed of these materials is one of the most significant environmental issues confronting us in the present day. Recycling polymeric waste is the most important action currently available to reduce environmental impacts worldwide and is one of the most dynamic areas in industry today. Utilizing this waste could not only benefit the environment but also promote sustainable development and circular economy management. In its program statement, the European Union has committed to support the use of sorted polymeric waste. This study reviews recent attempts to recycle this waste and convert it by alternative technologies into fine, nano-, and microscale fibers using electrospinning, blowing, melt, or centrifugal spinning. This review provides information regarding applying reprocessed fine fibers in various areas and a concrete approach to mitigate the threat of pollution caused by polymeric materials.

Plastic Waste Recycling

Plastic recyclates are granulates which are produced by the processing of plastic wastes. The circular economy package of the EU, especially the amendment of the Waste Framework Directive, sets a new goal for the use of different types of these recyclates. Corresponding primary raw materials can assure reliable qualities with respect to stable physical and chemical properties. Besides, the production of recyclates is often even more expensive than the production of primary raw material granulates. Several quality assurance measures are carried out along the value chain from plastic waste to final plastic products. Recyclates are evidently priced based on the price of primary raw material granulate. Pricing also correlates with different quality parameters, however, such as degree of mixing, degree of degradation and presence of impurities. This paper examines the correlation between different quality features and how they affect the pricing policy for recyclates. Experts and Stakeholders along the value chain of plastic recycling in Austria and Germany have been interviewed about the most important quality assurance parameters and how they (would) affect prices of recyclates. Therefore, quality parameters for the sorted plastic waste as an input for plastic waste recycling companies and manufactured recyclates are included in this paper. Experts from the plastic waste recycling industry confirmed that there is a profound correlation between price and quality that is presented and discussed in the paper: The higher the quality of the recyclates, the lower the level of impurities and the purer the recyclates, the higher the price.

Do So

The SARS-CoV-2 pandemic has demonstrated both positive and negative effects on the environment. Major concerns over personal hygiene, mandated and ease in lockdown actions and slackening of some policy measures have led to a massive surge in the use of disposable personal protective equipment (PPE) and other single-use plastic items. This generated an enormous amount of plastic waste from both healthcare and household units, and will continue to do so for the foreseeable future. Apart from the healthcare workers, the general public have become accustomed to using PPE. These habits are threatening the land and marine environment with immense loads of plastic waste, due to improper disposal practices across the world, especially in developing nations. Contaminated PPE has already made its way to the oceans which will inevitably produce plastic particles alongside other pathogen-driven diseases. This study provided an estimation-based approach in quantifying the amount of contaminated plastic waste that can be expected daily from the massive usage of PPE (e.g. facemasks) because of the countrywide mandated regulations on PPE usage. The situation of Bangladesh has been analysed and projections revealed that a total of 3.4 billion pieces of single-use facemask, hand sanitizer bottles, hand gloves and disposable polyethylene bags will be produced monthly, which will give rise to 472.30 t of disposable plastic waste per day. The equations provided for the quantification of waste from used single-use plastic and PPE can be used for other countries for rough estimations. Then, the discussed recommendations will help concerned authorities and policy makers to design effective response plans. Sustainable plastic waste management for the current and post-pandemic period can be imagined and acted upon.

Effective Product

Blends of polyethylene (PE) and polypropylene (PP) have always been the subject of intense reasearch for encouraging polymer waste recycling while producing new materials for specific applications in a sustainable way. However, being thermodynamically immiscible, these polyolefins form a binary system usually exhibiting lower performances compared with those of the homopolymers. Many studies have been carried out to better understand the PE/PP blend compatibilization for developing a high-performance and cost-effective product. Both nonreactive and reactive compatibilization promote the brittle to ductile transition for a PE/PP blend. However, the final product usually does not meet the requirements for high demanding commercial applications. Therefore, further PE/PP modification with a reinforcing filler, being either synthetic or natural, proved to be a good method for manufacturing high-performance reinforcend polymer blend composites, with superior and tailored properties. This review summarizes the recent progress in compatibilization techniques applied for enhancing the interfacial adhesion between PE and PP. Moreover, future perspectives on better understanding the influence of themodynamics on PE/PP synergy are discussed to introduce more effective compatibilization strategies, which will allow this blend to be used for innovative industrial applications.
