One of the social measures applied during the COVID-19 pandemic has been the use of personal protective equipment (PPE)—face masks and gloves. As a result, this waste category has expanded enormously. This study investigates waste management issues from multiple perspectives, including local governments, waste collection companies, and individual citizens in Poland using a telephone survey for institutions and an online questionnaire for individuals. The results of this study show that approximately 80% of local governments in the Silesian region have applied special measures for handling and collection of waste PPE. Only 13% of waste collection companies have applied special collection schedules for the waste generated at quarantine collection points due to the high costs of changing collection schedules, providing additional vehicles, and paying for more labor. The information campaigns focusing on new methods of PPE waste collection have been difficult to introduce on a large scale, and citizens need better information regarding how to handle and dispose of waste PPE. Results indicated the most helpful method in supporting waste PPE collection would be automatic PPE dispensers with waste PPE collection options and waste bags of a designated color. The respondents identified waste PPE pollution of the environment as an issue and the necessity for proper recovery of this waste stream.

1. Introduction

In March 2020, the World Health Organization announced that the outbreak of COVID-19, caused by the SARS-CoV-2 virus, had reached pandemic status [1]. Governments worldwide have faced a situation unprecedented in the recent history of civilization. There has been increased uncertainty and concern for public health around the world as governments have introduced special measures to prevent the spread of the disease. The regulations of health authorities have become the most important guidelines by imposing various restrictions on our daily activities [2]. Regardless of the cause of the appearance of the virus and other aspects of its epidemiology, one of the events following the declaration of the pandemic state was the introduction of potentially effective methods to limit the spread of the virus by individuals in a population [3]. In numerous countries worldwide, the use of personal protective equipment (PPE), face-covering masks and gloves in particular [4], has been required in public. New products have appeared for common and everyday use, which were previously used to a very limited extent in specific locations, such as public health facilities, hospitals, clinics, nursing homes, and in specific industries (i.e., electronic equipment manufacturing or food processing) [5,6].
The new PPE products are considered disposable after brief use. As a consequence, a new waste category has appeared. The mandatory use of PPE has been extended to many locations such as public transport, shops, supermarkets, or medical centers. In many countries, this requirement has also been applied to open spaces. This use has resulted in a significantly growing volume of disposed PPE items. In the European Union (EU), waste PPE can be classified as medical, separated, or mixed waste depending on the source of its generation [7]. Due to concerns of possible virus transmission from the surfaces of face masks or gloves and the increasingly common use of PPE in society, management of PPE waste has emerged as a challenging task that includes legal, business, and social aspects [8,9]. Management should combine methods of storage, collection, transport, and treatment of PPE. Also, all resources containing various raw materials are subject to further recovery, including for energy generation or recycling. The natural consequence of the introduction of the common and broad use of PPE is the need to implement a system and methods of collecting this waste, which requires cooperation between local governments, waste collection companies, local institutions, and each individual in society. Proper disposal also requires additional tasks, including preparation of waste collection schedules and adequate handling of waste from households and quarantined locations, including from persons with positive SARS-CoV-2 results and medical centers [10,11].
In Poland, infection protection measures have been similar to that of other EU countries. It is necessary to fulfill public health officials’ requirements, including using PPE to protect against SARS-CoV-2. After a single use, PPE becomes waste generated in households, workplaces, public transportation networks and hubs, shops, and supermarkets. Waste masks or gloves from the above sources should be disposed of in waste bins for mixed municipal waste, and different measures for the treatment of PPE are applied for the quarantined locations. Such places include locations inhabited by residents who had contact with persons infected by SARS-CoV-2, persons with COVID-19, or asymptomatic carriers of the virus [10,12]. Waste generated from these places should be qualified for municipal waste collection but considered possibly contaminated, and the PPE waste should undergo special handling and storage. Taking into consideration that the waste is originating from the sources where infected or potentially infected people reside, it is necessary to take precautions during the collection and transportation of such waste [13]. The waste management tasks for local governments include coordination of activities for monitoring persons required to isolate or in quarantine. The most important recommended elements of the waste management system for waste PPE collections in Poland are [14,15]:
  • providing bags assigned with a “C” label or of a designated color,
  • collecting waste at least every seven days,
  • providing direct transportation from collection points to the incineration plant or treatment facility for proper treatment of the waste, and
  • disinfecting the containers or waste bins.
Guidelines for healthy people and activities in public transport, shopping locations, and other social places to minimize the spread of SARS-CoV-2 include the collection of PPE in a separate box and then disposal into municipal waste containers. Additional proper collection measures include allocating specific times for waste collection and filling the bags to not more than 75% of their capacity, without compacting. Each activity associated with handling the waste requires using protective gloves.
The temporary storage of the waste PPE should be provided in the same containers as for the scheduled municipal waste collection. The requirements for the waste collection and treatment companies mandate that the COVID-19-related household waste complies with European Commission guidelines, in that it does not present a threat after nine days [11]. Residents improperly handling the waste (e.g., not entirely closing the waste bags) are required to be instructed by the waste collection company employees. The treatment of waste in the designated bags mentioned above should be provided on automated lines in the treatment facilities. If such installations are available, the waste stream should be directed for incineration. The collection companies should prioritize waste (including PPE) pick-up from infected households. Each person handling and touching the waste should wear masks and goggles.
To investigate the key players’ roles in the reverse supply chain, we have selected three target groups: local governments, waste collection companies, and regular citizens. The subject and the scope guiding this study is presented in Figure 1.
The main goal of this study is to determine how the new waste stream generated from households and other places including supermarkets, institutions, and medical centers, has affected each participant of the reverse supply chain. Employing exploratory research, the purpose is to gain an understanding of the methods, opinions, and motivations of policymakers, waste collection companies, and individuals. An investigation of the operational capability of the waste collection system is conducted to provide insight into the challenge of a new category of household waste. The results of the survey will help in working out a framework for further analysis.

2. Materials and Methods

Commonly used PPE is mainly composed of polymers, textiles, latex, or natural products such as cotton. The materials used in face masks can be woven fabric, textiles, cotton with rubber stripes, or with a textile band for fastening onto the face. The most commonly used gloves can be manufactured from latex or polyethylene foil. The materials used in manufacturing are relatively easy to recycle, but considering PPE is relatively small and lightweight, it can be easily mixed with other waste. Another possible method of waste PPE treatment is energy recovery by incineration. The calorific value of medical waste ranges from 19–24 MJ/kg, and polymers, including plastics, is 35–44 MJ/kg [16]. The commonly used surgical type face cover weighs approximately 3 g, and the mass of other types of masks with filters and strengthened edges is up to 16 g. Lightweight polyethylene glove mass is 0.8 g, and latex or nitrile gloves are within the range of 5–14 g depending on thickness and size. The incineration and waste-to-energy process should be considered a priority for waste PPE, knowing the potential medical hazards (collection from quarantined households or medical centers) and the high calorific value of the materials [17]. Another issue that has emerged in handling PPE waste is environmental pollution by plastics and micro-plastics via the disposal of waste masks and gloves in all locations [18,19]. This waste can pollute green areas such as parks, forests, or beaches, and is a serious issue in Asia [18,19,20]. A properly designed framework for waste management contributes to a positive response by individuals. The hierarchy of waste management regulations in emergency mode was adapted by individual EU members. The guidelines published by the EU [10] proposed a general approach for household management of people with coronavirus disease. In Poland, these guidelines were included in the legislation creating a framework of the necessary measures for public health protection [12,14]. Local government is responsible for supporting necessary information for waste collection companies and the residents. Each member of the EU has selected appropriate measures depending on WHO and EU guidelines and taking into consideration national Public Health officials.
We prepared a survey for local administration (i.e., the departments of local governments responsible) for waste management policy and waste collection companies. The study was conducted in the Upper Silesian region of Poland. The population in the Silesian region is approximately 4.5 million inhabitants, and the majority live in cities and towns [21]. There are 12 cities with more than 100,000 inhabitants, including the capital city Katowice with approximately 300,000 people. The region consists of industrial municipalities in a large conurbation and some rural satellite municipalities (Figure 2) [22]. By the end of August, a total of 66,900 cases of COVID-19 were reported in Poland, including 2040 deaths. In the Upper Silesian region, it was 20,300 positive cases and 478 coronavirus related deaths.
The research was divided into two separate surveys. The first part of the research included a telephone survey for the local government environmental departments responsible for waste management policy and control and waste collection companies for several municipalities in the Silesian region.
The main questions for local administration and waste collection companies focused on the three key activities in the practical approach of waste management: collection, transportation, and treatment of waste. The goal of each set of questions was to investigate the impact of a pandemic on the generation, handling, and collection of PPE. The local government representatives and managers of waste management companies were asked about differences between collection from quarantined locations and ordinary collection locations. The study examined the impact of special procedures and requirements from the public health authorities on PPE collection. The respondents were also encouraged to supply additional information and opinions concerning the practice of PPE collection. Data were collected from 11 local government offices covering an area with a population of over 800,000, including Katowice and 16 waste collection companies operating within an area with 1.3 million residents. The list of municipalities participated in the survey is shown in Table 1.
The number of respondents was a result of acceptance for participation in the survey. The difficulties with data collection from a larger number of municipalities occurred due to disruptions of regular working schedules and unavailability of employees from government offices and waste collection companies. The sequence of questions required answers from a representative of a local government office or waste collection company for the two scenarios: waste collection from quarantine and regularly scheduled waste collections. The other portion of the survey was an online questionnaire prepared for the residents and presented by student research group members from the Silesian University of Technology using social media (Facebook and WhatsApp). Example of the online questionnaire screenshots is presented in Figure 3.
The framework of the questionnaire was created using Google forms. It was conducted between the 6 and 24 of June 2020. The purpose of surveying residents was to identify awareness of individuals regarding handling, storage, and improper behavior with disposal waste PPE (Table 2). The online survey was chosen as a convenient method for accessing individuals. The set of questions explored the critical issues considering the generation of waste PPE in the reverse supply chain.
The intent was to determine Polish society’s response to the management, handling, and disposal of PPE. The research mainly focused on whether the residents had difficulties with waste PPE disposal, if the local government or waste management companies provided information about proper handling of used PPE, and what kind of behavioral issues are the main concerns for residents. Finally, residents were asked what kind of support in the collection of waste PPE is the most preferable. Table 3 includes details of the participants of the online survey.
Both parts of the survey were intended to summarize the effects of the pandemic and management of a new category of household waste (PPE) from the perspective of policymakers, the companies collecting, handling, and transporting the waste, and behavior and response from individual citizens. The results should highlight weak points in waste PPE management including business to customer relations in the reverse supply chain.

3. Results

The results from the first part of the survey, which was directed to local government environmental departments and waste collection companies, indicated a significant difference in approach between these two groups of entities. The survey included two separate groups of questions for ordinary waste collection points (residential or institutional) and places with quarantined persons, social welfare homes for older adults, and other locations. Although PPE is distinguished as a separate category with the potential hazard of spreading a virus, the requirements for the collection of this kind of product were not intended to introduce very strict measures for waste handling. The approach of waste collection companies would include the preparation of additional routes, vehicles, or changes in the schedules; as those measures incur additional operational costs, these companies were reluctant to apply changes. The results from the survey regarding the collection points with a positive or potentially positive SARS-CoV-2 test result, called quarantine points, are presented in Table 4. For clarity of results, the differences are separated for the two scenarios into no or minor measures and major or significant measures taken in management, collection, transportation, and treatment of PPE waste.
The results presented in Table 4 indicate various approaches towards management of waste PPE by local government offices and waste collection companies. Two scenarios of waste management show significant differences for the collection, transportation, and treatment of waste PPE. The primary guidelines from the Public Health Office included requirements for special treatment of waste PPE from households and strict safety requirements from quarantined locations. The local government offices followed the Ministry of Health and Head of Public Sanitary Office decrees regarding the collection, identification, and transportation of PPE waste and prepared information campaigns for waste collection companies. However, it was difficult to introduce special methods for the collection of PPE by waste collection companies waste due to various reasons. The most important was the additional cost factor for an additional category of waste collection. At the same time, the schedules of the waste collection had to be changed. The results show the requirement of financial support by the government for the increased cost of waste collection by the companies. The collection company managers indicated that the employees used protective gloves and masks while collecting waste from households.
Another portion of the survey focused on residents as a target group. Figure 4 shows the survey results for methods of disposal of face-covering masks and gloves. The majority of respondents indicated that the used PPE was disposed of together with mixed household waste.
Another question in the questionnaire concerned PPE disposal methods; specifically, which method is correct for the disposal of waste PPE. Almost 73% of respondents were not sure or did not know, 12% knew they should be collected separately, 8.5% thought they could be placed in the mixed waste container, and 5% knew they were collected in special bags. The respondents were asked if they noticed any improper methods of waste PPE disposal, and out of 150 respondents, 75% answered positively. The next question asked respondents what kind (if any) method for disposal had they observed. More than 60% of respondents answered that disposal in random places is the main issue, 32% had not noticed any significant issues, and 7% indicated wrong segregation of PPE.
Finally, the respondents were asked about proposals for the improvement of PPE waste collection. The results in Figure 5 indicate the overwhelming willingness of individuals to support the novel design of automatic dispensers with an option to collect waste PPE and use of bags with different colors to existing waste collection containers.
The waste stream of PPE generated from the households includes both face masks and gloves. Assuming daily activity of 20% of the population in the Silesian Region, it can generate 7.2 tons of waste face masks, and 12.6 tons of disposable waste gloves can be generated per day. The total calorific value ranges from 500,000 to 700,000 MJ per day.

4. Discussion

The majority of PPE products are intended for one-time use, introducing a new category of waste. Various management and environmental issues have emerged with widespread PPE use [23], including waste management decisions on the collection, transport, and treatment of waste, and the issues with social behavior in PPE waste disposal [24]. As indicated in the results of this study, waste management approaches differ between local governments and waste collection companies. From the local government point of view, it was relatively easy to prepare the requirements for all participants of the reverse supply chain following the guidelines of Public Health Service officials. The regulations included separating waste from ordinary collection points from that within quarantined locations, including quarantined households [11]. The results of the survey show more difficulties encountered by waste collection companies because of additional costs in changing collection methods or schedules. Even in some cases, it was necessary to modify waste collection vehicle routing or collect waste by special medical waste vehicles. The survey’s results indicated only a low number of waste collection companies were capable of fulfilling all requirements imposed by officials considering the collection, transportation, and treatment of PPE waste.
The major issue with the introduction of the changes for the waste collection planning was dynamically changing the location of quarantine collection points that are usually assigned for two consecutive weeks. A recent study by Kargar et al. discusses modeling and optimizing of the waste collection and transportation during an epidemic [9]. Following the difficulties with waste collection planning and additional costs, the companies preferred to conduct waste collection and transportation as it was previously planned but with additional protective equipment and rules for the employees, mainly also by using PPE.
The results show that the residents were not sure how and where they should dispose of PPE. This issue can be attributed to disturbances in the information flow between local government, waste collection companies, and the residents in emergencies. Under normal circumstances, schedules and waste collection plans for an individual waste stream are known in advance. However, when the pandemic began, it was difficult to predict that waste PPE products would emerge as an additional category of household waste. Also, there was no knowledge about the use of another type of bag or bin or associated labels. Broader information campaigns concerning new methods of waste collection were unlikely to be the topics of news headlines, especially as most of society was concerned about health issues and the geographic range of the pandemic. The results of this study also show that when a high number of individuals utilize single-use products, such as face-covering masks or gloves, it creates a large stream of resources with potential for recycling or energy recovery. Klemeš et al. indicated that during a pandemic we observe a significant surge in the volume of plastic waste. Therefore, potential short-term and long-term changes in plastic waste management practices are necessary [25]. In the Silesian region, PPE use can generate approximately 20 tons of waste per day. Proper management and handling of this waste stream require consideration of emissions and environmental burdens associated with waste products containing polymers [26]. We found among our respondents that improper disposal of PPE is an environmental pollution problem, which was consistent with the results of Kalina and Tilley [20]. Additional results indicated that individuals are eager to support new methods for the collection of waste PPE. Reverse logistics modeling that included medical waste transportation optimization methods was presented in a case study in Wuhan, China [27]. There are complex dependencies between government regulations, waste collection companies, and society. A top priority is the identification of interactions between key players as indicated in an example of interpretive structural modeling [28]. It includes the general framework of the collection schemes, new or modified bags or bins, schedules, and collection plans that can change dynamically, especially in urban areas. Future work can focus on the efficiency of the PPE collection including research in treatment plants and waste stream contents from mixed and separated fractions.
