1. Introduction
About 1.8 billion people worldwide work in agriculture, and they all rely on chemical pesticides, fertilizers, and other forms of crop protection to ensure that their families have access to enough food year-round. From 1950 onward, pesticides have been widely used in agriculture worldwide to protect crops from harmful insects and other pests [
1]. Pesticides have helped gain higher average output of rice and wheat since 1960 [
2]. However, this boost in agricultural production is not without cost. Harmful compounds present in containers after they have been used and emptied are dangerous to human and animal health and the environment [
3]. Proper pesticide container waste (p-waste) disposal is essential for these chemicals. It is important to pay attention to the material that remains after application and the locations where sprayers are applied [
4]. Many farmers do not know that they should not dump p-waste into a water source or compost it on their farms [
5].
Empty containers that have not been thoroughly cleaned may still contain remnants of contents, which could lead to complications in various contexts. Pesticide containers should not be thrown away since their contents harm the environment. The Food and Agriculture Organization of the United Nations (FAO) and the WHO issued a recommendation in 2008 listing several pesticide packaging collection, recycling, and disposal methods. Developed nations, such as Germany, Canada, Australia, and France, are among those whose strategies are effective [
6] and follow these recommended methods. Groups of experts and firms or groups set up in collaboration with pesticide manufacturers are responsible for collecting packets in these nations. To the authors’ knowledge, there have been limited studies in which individual farmers primarily collect and perform something to reuse p-waste.
The worldwide consumption of pesticides rose from 2,299,979 tons in 1990 to 4,122,334 tons in 2018. From 1990 to 2018, Asia used 1,777,740 tons (53%) of pesticides, followed by the Americas with 1,010,693 (30%), Europe with 465,556 (14%), Africa with 69,985 (2%), and Oceania with 42,522 (1.3%) tons. A total of 1,404,167 tons of pesticides were used in China between 1990 and 2018 [
7]. Regarding agricultural use of pesticides, Pakistan ranks second in South Asia [
8]. However, only a small percentage of Pakistani farmers (19%) are adequately trained in the safe application of pesticides and their waste [
9].
The existing linear economy (create, use, and dispose of) poses significant dangers to human health due to greenhouse gas emissions and environmental pollution, despite the widespread usage of plastic as a material in our daily lives. The circular plastic economy aims to reuse, reduce, and recycle all plastics to mitigate these problems [
10]. The transition to a circular economy (CE) has risen to the top of the strategic agenda for businesses worldwide. Chemical pesticides are unavoidable in today’s conventional farming [
6]. Farmers often use pesticides without knowing what kinds of these are or if there are any dangers to their families from these chemicals [
11]. The CE seeks to reduce the amount of trash produced and its adverse effects on the environment, society, and the economy. It also supports keeping the product and its material in use to regenerate the natural system [
12]. According to the Food and Agricultural organization, p-waste is increasing daily, so recycling p-waste benefits the environment and resources.
Several previous studies, such as Huyen et al. [
13] for Vietnam, Sharafi et al. [
14] for Iran [
14], and Shammi et al. [
15] for Bangladesh, highlight that there is a lack of pesticide-related awareness among farming communities. A lack of information related to the handling of pesticides has resulted in severe problems for human health and the environment [
16]. The recent fight against locusts, combined with Pakistan’s long history of pesticide use, has made these problems much worse. The farming community in Pakistan suffers from a lack of awareness, inefficient legislation, and technological know-how, all of which contribute to improper regulation of the use of pesticides [
17]. Most of the farmers throw their p-waste in canals and other water sources, disturbing the aquatic life and contaminating the water resource. Besides, many frames throw p-waste in their fields, polluting the environment. This contamination in sanitation and pure water is responsible for climate change.
To the best of our knowledge, no study has ever analyzed the impact of different socioeconomic and psychological elements on end users’ adoption of recycling p-waste. Most of the research is descriptive, and there has been little work encouraging end users to recycle their p-waste.
Previous research mainly focuses on managing waste rather than reusing waste, which connects the last node of the CE, such as dispose of, with the first one, such as create. Recycling is a procedure that involves breaking down or reprocessing waste materials to generate something new and valuable while also reducing pollution. It involves the process of refining waste materials to convert them into usable or new materials. The current research aims to solve this literature gap. More specifically, the theory of planned behavior (TPB) is applied in this context to evaluate the end users’ adoption of recycling p-waste. TPB offers a holistic framework for assessing multiple sociopsychological aspects of user behavior. It assumes that the users’ attitude and desire ultimately determine the outcome of any given situation. At the same time, experts agree that TPB is useful for describing individual intention-behavior [
18].
Extending the original TPB architecture is crucial for increasing its predictive power [
19]. This research also includes environmental concerns (ECs) to consider the previous lack of recycling and reuse of p-waste products. The study takes the aid of cross-sectional data collected from pesticide users. There are three main objectives of this study: First, it determines the socioeconomic characteristics of p-waste circularity of farming households in the district of Faisalabad. Second, it examines the adoption behavior of respondents toward p-waste recycling in the study area using the PLS model. Third, it suggests suitable policy recommendations based on the study results for concerned stakeholders. From the above-stated background, we put forward the following hypotheses:
H1. ATT positively affects the p-waste intention of recycling.
H2. SN positively affects the p-waste intention of recycling.
H3a. PBC positively affects the p-waste intention of recycling.
H3b. PBC positively affects end users’ adoption of recycling p-waste.
H4a. EC positively affects the p-waste intention of recycling.
H4b. EC positively affects end users’ adoption of recycling p-waste.
H5. p-Waste intention of recycling positively affects end users’ adoption to recycle p-waste.
In developing Asian countries, where occupational health laws are severely lacking, pesticide use has led to several indirect health and environmental problems, including the poisoning of beneficial animals and the contamination of air and water supplies [
19]. An increasing body of evidence suggests that pesticide waste, if disposed of incorrectly, poses significant risks to human health and the environment [
20]. Pesticide containers should not be thrown away since their contents harm the environment. Pesticide residues damage water and soil, and may adversely affect human and animal health [
21]. The existing linear economy (create, use, and dispose of) poses significant dangers to human health due to greenhouse gas emissions and environmental pollution, despite the widespread usage of plastic as a material in our daily lives.
This section gives a brief background of the article. The rest of the paper is divided into four sections.
Section 2 presents a brief literature review;
Section 3 presents the empirical methodology, including the data and empirical model, as well as the estimation techniques being applied.
Section 4 describes the empirical findings and discussion regarding the study results. The last section concludes the study and presents policy suggestions based on the results.
2. Research Context
This section presents previous relevant studies. It is not surprising that apart from a few studies, almost all provide similar findings based on secondary source data or descriptive results. In this regard, Damalas et al. [
4] conducted a study in Greece, and the results found that farmers’ training programs reduce the risks associated with pesticide usage. Plianbangchang et al. [
22] explored a study regarding pesticide use methods in Thailand, and the results showed that farmers frequently looked to commercials for advice on which pesticide to apply. Patarasiriwong et al. [
23] identified a workable methodology for managing trash from pesticide packaging for the local environment. The study suggested essential elements, including the multiple rinse method, a central collection site operated by the community, a waste recovery program provided by pesticide production companies, and government registration and regulations for sanitary glass-bottle-washing facilities. Veiga [
24] performed an exploratory study for Brazil, and the findings showed that the reverse logistics program is ineffective for small rural areas, despite its overall success.
Yang et al. [
25] perused a study in two rural areas of the Wei River catchment in China, where farming practices and erosion levels were substantially different. They used canonical correspondence analysis, and results revealed that education levels and ages significantly increased the hazards associated with pesticide use. Agrawal et al. [
26] highlighted the future ways for research gap analysis by reviewing the literature. Chau et al. [
27] analyzed a survey that different sources of drinkable water and impurities with pesticides provide information on probable factors contributing to exposure to pesticides in Vietnam.
Abadi [
28] investigated that the increased usage of pesticides in central Iran is a significant issue; however, the study did not find any relevant witnesses regarding the elements contributing to the problem. Aldosari et al. [
29] examined farmers’ pesticide knowledge and dependence on sustainable pesticide use. The results showed that most farmers did not obtain any training on pesticide use sustainably; on the other hand, research told that pieces of training might be helpful for sustainable pesticide use. Bagheri et al. [
30] explored a study for apple farmers and examined standard safety procedures for pesticides. For rural China, Jin et al. [
31] found a short-term decrease in land pollution due to high use of certain pesticides. Sharafi et al. [
13] insisted on comprehensive training education and implementing the waste management system for environmental sustainability.
Bagheri et al. [
32] observed that the handling of pesticides in agriculture had been the subject of research, but the factors that motivate farmers to utilize pesticides are not better understood. Bagheri et al. [
33] found that farmers’ understanding of pesticide usage, attitudes toward risks, and perceptions of safety all play crucial roles in ensuring spraying operations. They concluded that farm-level improper p-waste disposal harms the environment and the general public’s health.
Ali et al. [
34] advised policy to minimize the gap between crop growers, locals, and other stakeholders, including governmental organizations and retailers. Van den Berg et al. [
35] studied that human and environmental health are likely compromised at different points in the pesticide lifetime. Li et al. [
36] found that the perceived benefits positively impact perceived risks and willingness harms green dumping behaviors and willingness. Acerbi et al. [
37] proposed a reference model by developing a conceptual data model to standardize and structure the necessary data in circular manufacturing to support manufacturers’ decision-making process. Sassanelli et al. [
38] detected existing CE performance assessment methods and developed a positioning framework for measuring and assessing the circularity degree of a company. Vinante et al. [
39] found that most of CE metrics are sufficiently general and applicable in assessment procedures, irrespective of the firm size and geographic location.
Bagheri et al. [
40] for Iran used PLS and found that attitudes favor intention, whereas perceived behavioral control has a negative effect. Furthermore, SN has no significant effect on intention. They concluded that extension education should focus on changing farmers’ intentions and actions toward sustainable pesticide usage by altering their attitudes and perceptions of behavioral control. Garbounis and Komilis [
41] anticipated the pace at which unused pesticide containers are being produced on a local, state, and federal scale. Salmenpera et al. [
42] found that waste management businesses play a role by offering waste processing treatment to meet the needs of the production sector. Cishahayo et al. [
43] found that farmers who participated in self-learning and social learning have a greater environmental protection awareness. We noticed that the impact of circularity practices and waste management technologies on environmental pollution related to farm waste in the form of pesticides has not received considerable attention in the current developing economies’ circularity literature.
The use of pesticides and their waste contaminate the soil, water, and environment. Governments and industries should manage technical education, regulations, and integrated pest control management to upgrade the living standard. The literature on waste management shows that it lacks specificity regarding managing waste products parallel to ecological sustainability [
44,
45]. Pesticide packaging is composed of plastic, which does not break down easily and thus negatively affects soil quality [
14]. These pesticide management techniques can save the environment, soil, and groundwater from deterioration. On the other hand, these can have disadvantages for farm production. These can reduce farm production and disturb the food supply chain [
46].
3. Materials and Methods
In this research, both quantitative and qualitative data were collected. A well-structured and accurate questionnaire was used to collect information from the target population. Before collecting, the required information questionnaire was pretested to validate it. After pretesting, data were gathered from farmers regarding the recycling of p-waste in the context of the CE. Due to time and resource limitations, the Faisalabad District of the Province of Punjab (Pakistan) was selected. The farm survey was conducted from 2 to 17 April 2022 with the help of a team of trained enumerators who were graduate-level students. As data are homogenous in nature, we applied simple random sampling, which is a probability sampling method, and here, each unit has an equal probability of being included in the research sample. In probability sampling, randomly chosen sampling units that are appropriately picked may indicate the entire sampling population. For this study, information was gathered from 230 respondents, but after obtaining the data, the proper accurate respondents were 210, and the response rate of our survey data was 91.3%. In the questionnaire, only a few questions were open-ended, while others were closed-ended. Questionnaires were formed on a 5-point Likert scale, and the 5-point Likert scales ranged from strongly disagree to strongly agree for measuring the variables.
Faisalabad is located in Punjab Province, the third-most-populated city in Pakistan and once known as Lyallpur. Here, a total of 3,625,000 people are living in Faisalabad as of year 2022 with an increase of 2.34% since 2021. The entire size of the district is 5856 square kilometers. It is located between latitudes 30.35 and 31.50 north and longitudes 72.66 and 73.40 east. It contributes more than 20% of the Province of Punjab’s GDP. In District of Faisalabad, there are six tehsils (Chak Jhumra, Faisalabad City, Faisalabad Sadar, Jaranwala, Samundri, and Tandlianwala). These tehsils are administrative units of the district, and all of these were taken in the study sample. The lower Chenab canal irrigates the crops farmed in Faisalabad, including cotton, wheat, sugarcane, fruits, and vegetables. The district is also known as the Manchester of Pakistan, and it is the third largest city in Pakistan after Karachi and Lahore and the second largest city in Punjab after Lahore. This study is taken only at the Faisalabad level because of time and resource constraints.
3.1. Data Analysis
Structural equation modeling (SEM) is a well-known analysis tool for many research fields. The partial least square (PLS) of the SEM is based on coherence and especially when data are not correctly partitioned. PLS uses partial least squares path modelling and provides a graphical interface based on SEM [
47]. The PLS path modelling (also called the soft modelling technique) has the lowest measurement scale requirements, sample size, and residual distribution. Besides, it includes modular methods for calculating bootstrap signal spacing, model parameters, and multiple quality indicators. These algorithms are becoming increasingly popular in other areas, such as PLS algorithm information system research and marketing [
48]. The PLS analysis is based on the part of the model that has a large number of predictors. PLS also provides expected results for structural models, structural and reflective models, and good fit quality [
49]. PLS was chosen for the study because it facilitates the investigation of formative constructs. Software for SEM that uses covariance is better than PLS-SEM because it was initially created for prediction [
50].
This study takes attitude, EC, perceived behavioral control, and subjective norms (SN) as independent variables and checks their impact on dependent variables, such as intention and adoption of recycling p-waste. The association between constructed and related items has been determined using the measurement model (outer model). However, as a way to find out the association between endogenous and exogenous constructs, the structural (inner) model was applied. This study used several reliability tests for measuring. Path coefficient, t-value, and p-value are used in structural models to determine the significance of each variable.
Additionally, the R square was discussed, which helps evaluate the validity of the whole model. We now have the fundamental framework for compiling reliable data and conducting research. Sreejesh et al. [
51] looked at three significant categories of research: exploratory, descriptive, and explanatory. Using factual or statistical techniques, explanatory research has been used to evaluate the hypothesis and measure the links between variables [
52].
In this study, the data are collected via face-to-face interviews of farmers. To ensure the validity of the questionnaire, face-to-face distribution was chosen. Validity and reliability are essential for the model to work. Loading and composite reliability are employed to ensure the measurement model’s accuracy, while discriminant and convergent validity serve as the cornerstones of model validity [
53].
3.2. Internal Consistency Reliability
An internal consistency reliability approach was employed to assess the data’s dependability. The data items were organized into groups based on the types of factors, and each factor’s factor loading and internal consistency reliability were checked. For the sake of this study, factor loading is taken to indicate how well a collection of items assesses a single latent notion. Many researchers who have studied the subject of factor loading requirements have suggested a value greater than 0.7 as a significant value [
54]. The conceptual framework of the study is given below in
Figure 1.
ATT, EC, PBC, and SN show the independent variables in this framework. Meanwhile, the variables INT and adoption of recycling p-waste (ADP) are independent variables. The study checked the impact of selected explanatory variables on both explained variables. However, null hypotheses of the study explained previously in the introduction are shown here as H1, H2, H3a, H3b, H4a, H4b, and H5 in the figure.
5. Discussion
To guarantee CE practices, the research aims to investigate how end users adopt p-waste recycling practices. The study’s specific goal is to employ an expanded TPB framework to understand better how end users’ adoption behaviors relate to recycling p-waste. As a result, the current research represents an innovative effort to close this gap. A structural model is suggested by utilizing the TPB theoretical framework. Environmental concerns are also included to increase the TPB framework’s explanatory power. This extension suggests that attitude, subjective norms, PBC, and environmental concerns influence an end users’ intentions and adoption of recycling p-waste. We also contend that intentions influence the adoption to recycle p-waste. According to the analysis’s findings, five of the seven hypotheses are supported, while the others are not.
The impact of pesticides on the crop is very significant; they enhance the crop’s production but also pollute the soil and water quality [
64]. FAO concluded that insect attacks reduced agricultural productivity in developed countries by 35% before and 20% after harvesting. Hellweg and Geisler [
65] explain that pesticides are active biotic materials that escape the environment, and this life cycle of pesticides reduces environmental quality. Most of the farmers throw their p-waste in the field, regular garbage waste, and water canal streams; only some burn them.
The PLS-SEM findings confirmed that attitudes, subjective norms, and environmental concerns significantly positively impacted intentions to recycle p-waste. Perceived behavioral control, however, did not suggest an influence on intentions. The adoption of recycling p-waste, however, seemed to be positively and significantly impacted by perceived behavioral control and intentions to recycle p-waste. Environmental concern does not influence the adoption of recycling p-waste in the sample area but has a significant favorable influence on intentions. The findings seem to support hypothesis H1, which examined the connection between attitude and intention to recycle p-waste, and this result agrees with the findings of Dhir et al. [
66]. Similar to H1, H2 is also supported, indicating a positive association between intentions and subjective norms, and this outcome is consistent with earlier research [
18].
Additionally, among the factors influencing recycling p-waste, subjective norms impact intentions to recycle. Such results may be attributed to the collectivistic nature of Pakistani culture, which values collaboration and synergy. As a result, the end users’ activities are impacted by how their social circle perceives him or her.
H3a looked at the relationship between PBC and the intention to recycle p-waste. According to the results, H3a is not significant, which is in line with the findings of Shi et al. [
67]. The finding of H4a is validated and suggests that environmental concern significantly impacts intentions to recycle p-waste, and this result is consistent with a research on pro environmental intentions [
67]. Around the globe, environmental deterioration is a problem. To address the issue, initiatives in the form of CE practices are required.
The findings show that respondents are aware of environmental problems and are eager to implement CE strategies, such as recycling p-waste. As the present research is the first endeavor to comprehend end users’ adoption behavior toward p-waste recycling, our results on H3b and H5 are exceptional in p-waste management. H3b investigated the impact of PBC on the adoption of recycling p-waste, demonstrating that PBC has a significant impact on the adoption of recycling p-waste, and Sanchez et al. [
68] showed similar findings about reducing noise pollution. Results also show that PBC strongly predicts p-waste recycling adoption. The findings also show that H5, which looked at the impact of intention on the adoption of p-waste recycling, is validated. This result is in line with other research that found a positive effect of intentions on the adoption of recycling p-waste [
69]. Therefore, respondents are aware of the harmful effects of p-waste and are prepared to recycle them.
6. Conclusions and Policy Recommendations
In CE, waste becomes valuable material and can be reused and recycled. The current research uses TPB to evaluate the end users’ adoption of recycling p-waste. The study analyzes seven hypotheses and six variables, for example, attitude, perceived behavioral control, EC, SN, intention, and adoption. Countries are developing strict policies to ensure effective p-waste management since p-waste is becoming a global concern. Most nations require manufacturers to be financially responsible for managing p-waste, which exerts monetary pressure on the producers. P-waste management is also sometimes a nonprofitable business due to uncertainties (quantity, quality, and time of p-waste dumping), which could endanger the survival of concerned firms for CE. Therefore, financial responsibility for p-waste management should be shared among all stakeholders to continue the reuse or recycling of p-waste. According to the study findings, the end users’ adoption of recycling p-waste positively correlates with PBC and recycling intentions. Meanwhile, p-waste recycling intentions indirectly impact the end users’ adoption to recycle p-waste due to attitude, SN, and EC.
The current study provides insightful information about end users’ intentions to support reverse logistics for legislators and decision makers. Several types of research indicate that people are becoming more concerned about environmental damage; results show that they want to adopt recycling behavior. Similarly, we discover a favorable correlation between PBC and the adoption of recycling p-waste. In contrast to Western civilization, Pakistani society is a socialistic society where family, coworkers, friends, role models, and other significant individuals are the main factors affecting people’s decisions. Our findings support this, which shows that SN is the main predictor of intentions to recycle p-waste. SN could be promoted by (1) using role models and influencers to spread information, (2) offering instruction on subjects in universities and schools, (3) planning awareness campaigns, and (4) utilizing social media platforms to interact with others, as many do so to remain in touch and make new relationships. Besides, people appear to have a positive attitude toward recycling p-waste, as evidenced by the positive correlation between attitude, EC, and intentions.
The main conclusions of our study suggest promoting farmers’ recycling behavior of p-waste, boosting social norms, improving farmers’ attitudes, EC, and enhancing PBC. The specific actions that can be taken are as follows: (1) to construct an easy p-waste recycling policy system; (2) to give knowledge of a good environment and the importance of recycling; (3) through the publicity of concern content of p-waste, to convey to farmers to start p-waste recycling; (4) to start pilot programs of recycling in key regions; and (5) by upgrading the framework to help p-waste recycling, to enlarge the number of recycling points, by saving time and the economic cost of the farmers. Additionally, as necessary, incentives can be considered while putting these measures into practice.
The current investigation uses cross-sectional data, which might be affected by social desirability bias. Therefore, further work might confirm our results by using various research designs, such as experimental designs, longitudinal studies, or multisource data, in which social desirability is not a concern. The research is being conducted in the city of Faisalabad, which is located in Pakistan. Study findings may be modified to apply them to other developing nations. As a result, we advocate for more research to evaluate and verify this work in contexts that span different regions to broaden its applicability.
