Enhancing compliance with waste sorting regulations through inspections and motivational interviewing.

This field experiment investigates the effect of first-time inspections of restaurants' waste sorting and explores whether motivational interviewing (MI) training of inspectors in this specific setting enhances the propensity of restaurants to be compliant with regulations. Our results show strong positive effects of first inspections with an average improvement of 55%. Also, the MI training of inspectors seems to affect compliance. However, this may also be a combined effect of the first inspection, MI training and more days between inspections. Further research is needed.

Sustainable waste management solutions for the foodservice industry: A Delphi study.

Foodservice businesses influence the sustainability of their natural environment by producing significant amounts of waste. Yet, research has, thus far, been dominated by studies that limit their scope to food waste alone. Few studies have taken a broader look at sustainable waste initiatives, including innovative waste processing techniques, with a view to constructing management indicators for foodservices. This study combines management innovation practices related to resource management, waste prevention, processing and disposal techniques, and stakeholder involvement to offer sustainable standards. It primarily adopts the Delphi technique to propose specific solutions pertaining to waste management. Experts from government, industry, and academia reveal that potential waste management initiatives comprise three facets - service, process (operational), and organisational practices and innovations, 15 sub-facets and 41 indicators. This study thus establishes a catalogue of solutions for food, packaging and other 'non-food' waste that foodservice establishments can implement. In addition to its practical implications, an important contribution is its focus on management systems to establish waste management standards for hospitality, food and beverage (F&B) services, restaurants, and non-commercial catering.

Determinants of Unsafe Plastic Waste Disposal among Households in the Tamale Metropolitan Area, Ghana.

Background: The global discourse on plastic waste generation and disposal has over the last two decades, gained traction with the aid of research-based evidence. Though observed globally, the situation is quickly deteriorating in developing countries such as Ghana. In Ghana and Africa as a whole, rapidly increasing population and rural to urban migration have been cited as factors that exacerbate the existing struggles with plastic pollution. This study aimed at identifying the determinants of unsafe plastic waste disposal among households. Methods: The study was carried out in three communities in Tamale in the Northern Region of Ghana. Data were collected from 270 randomly selected households through household surveys, key informant interviews, and direct field observations. Results: The study revealed that the majority (63.3%) of the total respondents used and disposed of their plastic waste "unsafely." The analysis showed that the education level and household wealth were significant determinants of unsafe plastic disposal. Conclusion: The study concludes that challenges of plastic waste management are not limited to economic, technical, and institutional factors, but social factors such as human behavior are key aspects of waste management that need attention. The study, therefore, recommends strict enforcement of sanitation by-laws, promotion of education, and provision of alternatives to plastics that will minimize the need for importing and manufacturing plastics, as potential steps towards addressing unsafe disposal of plastics in the domestic environment.

Improper disposal of face masks during COVID-19: unheeded public health threat.

Ethiopia confirmed its first case of the novel coronavirus (COVID-19) pandemic in March 2020. As a means to tackle the spread of the virus, the government opened a campaign for the public to exercise hygiene measures such as washing hands frequently and physical distancing. A few weeks later, a five-month State of Emergency (SOE) was declared, and several businesses, schools and theatre halls were closed. People were advised to work from home, including permitting telecommuting for many government officials. However, mainly due to fear of economic crisis, the government was forced to release the lockdown and mass wearing of face masks has become a requirement. As health professionals and the government insist that people make use of facemasks, it is also equally important to give guidance on how to dispose of them safely because face masks that are disposed improperly have the potential in spreading SARS-CoV-2. The urgency of this comes in people's violations of rules when it comes to disposing of masks they used. Providing awareness creation programs about the negative impact of contaminated face masks on the health of individuals and introducing laws that can prohibit improper disposal of used personal protective equipment (PPEs) are among the solutions discussed in this manuscript that could help reduce the problem.

Unhygienic stool-disposal practices among mothers of children under five in Cambodia: Evidence from a demographic and health survey.

BACKGROUND: Unhygienic disposal of children's stools affects children's health in terms of their susceptibility to many diseases. However, there are no existing studies into the impact of unhygienic stool disposal in Cambodia. Therefore, this study aimed to identify factors associated with the unhygienic disposal of children's stools among children under the age of five in Cambodia. METHODS: An analytical cross-sectional study was conducted using data from the Cambodia Demographic and Health Survey (CDHS) 2014. A multivariable binary logistic regression was conducted using Stata to analyze factors associated with the unhygienic disposal of children's stools. RESULTS: Overall, the prevalence of practicing unhygienic disposal of children's stools was 29.27% (95%CI: 27.51%- 31.09%). Factors statistically associated with this practice were: living in the Central Plain, Plateau and Mountains, Coastal and Sea regions (AOR = 1.65; 95% CI: 1.33-2.04), (AOR = 2.53; 95% CI: 1.98-3.24) and (AOR = 4.16; 95% CI: 3.15-5.48) respectively, poor household wealth (AOR = 1.58; 95% CI: 1.31-1.91), the mother having no education (AOR = 1.45; 95% CI: 1.14-1.85), a high number of children aged under five (AOR = 1.11; 95% CI: 1.03-1.20), being in the "other" religious category (AOR = 1.77; 95% CI: 1.25-2.51), living in a household with unimproved toilet facilities (AOR = 1.22; 95% CI: 1.11-1.34), living in a household with inadequate hygiene (AOR = 1.33; 95% CI: 1.12-1.59), and the household not being visited by a family planning worker in the last year (AOR = 1.45; 95% CI: 1.19-1.77). However, an increase in the child's age by even a month had significant negative associations with unhygienic practice (AOR = 0.65; 95% CI: 0.60-0.70), even when controlling for other covariates. CONCLUSION: Almost one third of the mothers do not practice hygienic disposal of children's stools in Cambodia. Unhygienic practices were more prevalent in certain regions, and were also associated with low wealth, lack of education, an increase in the number of children under five in the household, religion, lack of sanitation and access to healthcare professionals. Conversely, the child's age was found to be positively associated with the hygienic disposal of children's stools.

Conceptual Behaviour Underpinning the Occurrence of Nonfaecal Matter in Faecal Sludge in Some Urban Communities, Ghana.

Faecal sludge (FS) management is pertinent to the achievement of sustainable development goal 6.2 around the world; yet it is constrained by urbanisation challenges, waste management complexities, and defective attitudes. These deny communities of the plausible supply of resources from FS. This paper assesses the perception underpinning the occurrence of nonfaecal matter in FS in Ghana. Primary data were obtained from 400 respondents in four communities in Brong Ahafo and Greater Accra Regions of Ghana, using a structured questionnaire. Data were analysed by using STATA software version 15. Chi-square test and multiple logistic regression were conducted on all independent variables and statistical significance was accepted at p < 0.05. The study identified the following as the most perceived frequently disposed nonfaecal matter into FS: sanitary pads and diapers (38.5%), fabrics/rags (23.2%), toilet rolls (20.8%), razor/shaving sticks (10.3%), and others (7.2%). Gender, state of toilet facility (roof or unroofed), presence of container for collecting other types of waste in the toilet room, and state of container in toilet room either covered or uncovered were the factors found to be significantly associated with the disposal of solid waste (SW) into FS at 95% confidence level. The fear of exposing used sanitary materials for rituals, the use of fabric as an alternative to toilet rolls, and the desire to conceal aborted pregnancies from the public were some of the reasons alluded to the disposal acts. Education and awareness campaigns on proper SW disposal practices, appropriate use of toilet facilities, and the resource potentials of FS were found to be the best way forward to discourage indiscriminate disposal of SW into FS.

Individual and contextual factors associated with disposal of children's stools in Papua New Guinea: evidence from the 2016-2018 demographic and health survey.

BACKGROUND: Proper sanitation has been one of the topmost priorities on the global public health agenda. In the past few decades, sanitation programs targeting households have often paid little attention to the disposal of children's stools. We assessed the individual and contextual factors associated with disposal of children's faeces in Papua New Guinea. METHODS: The data used for this study forms part of the 2016-2018 Papua New Guinea Demographic and Health Survey (PDHS). For this study, we focused on women with children less than five years (n = 2095). Both descriptive and inferential analyses were carried out. Descriptive statistics were used to summarize the data, using frequency counts and percentages. The inferential analysis used multilevel logistic regression models to investigate the individual and contextual factors associated with disposal of children's stools. These models were presented as adjusted odds ratio (AORs), together with their corresponding 95% confidence intervals. Statistical significance was set at p < 0.05. RESULTS: More than half (56%) of the women had disposed of their children's stools unsafely. With the individual level factors, the results showed that women with children < 12 months [AOR =1.71; CI = 1.28-2.29] and women aged 20-24 [AOR =2.58; CI = 1.24-5.37], 35-39 [AOR =2.34; CI = 1.09-5.04], and 40 years and above [AOR =2.51; CI = 1.09-5.79] were more likely to practice unsafe disposal of children's stool. The odds of unsafe disposal of faeces was also higher among women who visited the health facility for child diarrhea [AOR =1.69; CI = 1.25-2.28]. With the contextual factors, the odds of unsafe disposal of children's stool was higher among women who lived in the Southern region [AOR =4.82; CI = 2.08-11.18], those who lived in male-headed households [AOR =1.79; CI = 1.19-2.70], and those who had unimproved toilet facilities [AOR =1.96; CI = 1.39-2.76]. On the contrary, women with unimproved source of drinking water were less likely to dispose of their children's stool unsafely [AOR =0.54; CI = 0.35-0.83]. CONCLUSION: Both individual and contextual factors predict unsafe disposal of children's faeces in Papua New Guinea. It is recommended that sanitation programs should focus on behavioral change and not only on the extension of water and improved toilet facilities. Such programs should also focus on both individual and contextual factors of women.

Poor and Unsatisfactory Disposal of Expired and Unused Pharmaceuticals: A Global Issue.

Pharmaceuticals are beneficial to humankind and emerged as crucial arms to treat/manage multiple disease pathogenesis in the present era. In analogous, these medicines/ medical devices should be used cautiously as they possess a potential threat to induce multiple undesired effects that may be related to human health or the environment. Daunting effects may arise due to the improper disposal of unused/expired medicines. Hence, to minimize such harm, there should be adequate knowledge and practice among the population regarding the safe disposal of unused/expired medicines or related pharmaceutical devices. The lack of approved information regarding safe disposal of such substances may invite serious concerns like environmental pollution, which may induce immediate health hazards to the present population and upcoming future generations. There are numerous ways to dispose of, or manage the unused and expired pharmaceutical substances. Sharing the medicines among siblings, friends, and family members are never free from serious health risks. Storing the unused and expired medicines in the home increases the risk of intentional or accidental ingestion of such substances and may create a health emergency. Disposing medicines like household and municipal waste may lead to environmental pollution and harm to humans and animals. The present review finds the multiple unsafe ways of disposal of unutilized medications/tools. Furthermore, it also summarizes the disposal pattern of unutilized medications among the few developed and undeveloped nations.

Food waste tendencies: Behavioral response to cosmetic deterioration of food.

American households discard a significant amount of food that represent a sizable portion of their food expenditures. This study adds to our understanding of product attributes associated with food waste, with a focus on cosmetic deterioration during home storage. Specifically, we profile a sample of U.S. individuals by patterns of common food-related behaviors and determine the effects of product attributes on food waste tendencies at the point of consumption by distinct behavioral profiles. An interactive survey at the Minnesota State Fair (N = 333) was used to obtain measurements on food-related behavior and sociodemographic factors. The survey included a conjoint task to elicit food discard tendencies to construct the food waste proxy. The study considered cosmetic deterioration, date labels, implied shelf life, package size, and prices paid, in fresh, packaged spinach and ground beef products. Factor analysis and latent class modeling categorized the sample into two classes, revealing distinct food-related behavioral patterns. Planners, who constituted a slight majority in our sample, were likely to have established pre-shopping and in-store behavior and food management and cooking skills. Extemporaneous Consumers had inferior food handling routines and were less knowledgeable and skilled in the kitchen. Regression analysis using a random-effects tobit model showed Extemporaneous Consumers were prone to waste a greater portion of the spinach product than Planners. Otherwise, both classes showed similar increases in likelihood to discard the products, as their appearance deteriorated. Their tendency to waste increased with shorter remaining shelf life for spinach but not for ground beef, and was not affected by the date label type. Results suggest an intervention that targets a general audience designed to enhance people's skills to discern edibility of food in home storage by manipulating sensory expectations from cosmetic deterioration could be impactful in efforts to curtail food waste.

Correlates of appropriate disposal of children's stools in Malawi: a multilevel analysis.

BACKGROUND: Management of children's stools is an important aspect of achieving open defecation free communities and reduction of diarrhea. However, information regarding individual- and community- level factors associated with safe child stool disposal in Malawi is limited. The current study aimed to assess the prevalence of safe child stool disposal and the associated individual- and community- level factors in Malawi. METHODS: The cross-sectional study used data from the 2015-16 Malawi Demographic Health Survey in which 6326 children aged under 2 years, nested within 850 communities, were analyzed. Individual- and community- level factors were tested for association with safe child stool disposal practice using multilevel logistic regression models. RESULTS: Results revealed that 85.6% of the women reported to have safely disposed of their children's stools. Women from households with improved sanitation had 36.0% greater odds of safely disposing of their children's stools compared with those from households with unimproved sanitation [(adjusted odds ratio (aOR): 1.36; 95% confidence interval (CI): 1.12-1.65). Further, women from communities with a middle (aOR: 1.62; 95% CI: 1.18-2.21) and high (aOR: 1.45; 95% CI: 1.14-1.84) percentage of educated women were more likely to have their children's stools safely disposed of than those from communities with a low percentage of educated women. Children's age, media exposure, and region were significantly associated with safe stool disposal. CONCLUSION: Both Individual- and community-level factors were revealed to be important factors for child stool disposal. Public health strategies designed to promote sanitation/safe child stools disposal need to conduct thorough community assessments to identify community-specific needs/barriers. Additionally, public health practitioners should take into consideration the geographical and wealth inequalities when designing programs aimed to improve safe child stood disposal.

Prevalence and Predictors of Storage of Unused Medicines among Households in Northwestern Ethiopia.

Background: Unused medicines are those that are expired, discontinued, deteriorated, and/or not intended for any future use. The aim of this study was to assess the prevalence of unused medicines and predicting factors in households of Awi zone, Amhara regional state, Northwestern Ethiopia. Methods: A community-based cross-sectional study was conducted. A survey of unused medicines was conducted through interviews with representatives of households. The collected data were entered with Epi Data version 3.1 and exported to SPSS version 21 for analysis. Predictors of storage of unused medicines were assessed through binary and multivariable logistic regression methods. A confidence interval of 95% and a P-value of <0.05 were considered to declare statistical significance. Results: Of the total of 507 households surveyed, 70 (13.8%) were found to have unused medicines. These constituted twenty-eight types of unused medicines. Anti-infective medicines were the most commonly unused medicines, 58.9%. People who pay for medicines by themselves, those who lacked knowledge about medicines, and those who did not receive enough counseling about medicines they took were found to be 2.6, 4.8, and 3 times more likely to have unused medicines, respectively. Conclusion: A significant amount of unused medicines was present in the community. Strategies aimed at educating the public regarding the safe disposal of unused medicines and an organized method of collection and disposal of unused medicines in the community need to be introduced.

Proper Disposal of Prescription Opioids in Southwest Virginia: Assessment of Patient, Physician, and Medical Student Beliefs and Practices.

CONTEXT: Southwestern Virginia demonstrates the highest regional mortality rate from prescription opioid overdoses. Nationally, 65% of patients misusing opioid medications received them from friends and family, underscoring the need for effective disposal of unused narcotics. OBJECTIVES: (1) To understand patient, provider, and medical student beliefs and misconceptions regarding proper methods of opioid disposal; (2) to characterize discrepancies that exist between patient self-reported habits and medical student/provider perceptions of opioid usage, disposal, and diversion. DESIGN: Descriptive, cross-sectional, observational study. SETTING: Large, nonprofit health care organization and allopathic medical school in Southwestern Virginia. PARTICIPANTS: All ambulatory patients 18 years or older presenting for elective consultation at health system orthopedics department; all institutionally employed physicians with active system e-mail addresses; and all current students at the associated medical school. MAIN OUTCOMES/MEASURES: Patients: The number who had received information regarding proper methods of opioid disposal, intended disposal method, methods of disposal considered appropriate, comfort level with opioid disposal, and demographic data. Physicians and Medical Students: The number who had received instruction regarding proper methods of opioid disposal, acceptable means of opioid disposal, most appropriate disposal method, disposal method most likely to be employed by patients, practice profile/prescribing data, and medical school year. RESULTS: In total, 64% of patients (n = 255/750) had never received instruction from a physician regarding opioid disposal; 56% of physicians (n = 212/732) and 78% (n = 80/171) of medical students indicated that they never received formal instruction regarding methods of disposal. The majority of physicians believed that their patients are most likely to use in-home methods of disposal or store prescription medications for future use; 61% of patients indicated a preference for accessible disposal facilities. CONCLUSIONS: The discrepancy between patient and physician responses highlights a lack of communication regarding disposal of unused opioid medications and is a target for future intervention.

Pathogen Reduction Potential in Anaerobic Digestion of Organic Fraction of Municipal Solid Waste and Food Waste.

Anaerobic digestion (AD) is a commonly used method of processing waste. Regardless of the type of the used digestate (fertilizer, feedstock in case of solid-state fermentation, raw-material in case of thermal treatment) effective pathogen risk elimination, even in the case of high pathogen concentration is essential. An investigation of the survival time and inactivation rate of the Salmonella Senftenberg W775, Enterococcus spp., and Ascaris suum eggs during thermophilic anaerobic digestion performed on laboratory scale and confirmation of hygienization in full-scale operation were performed in this study. Except for sanitization efficiency, the AD process performance and stability were also verified based on determination of pH value, dry matter content, acidity, alkalinity, and content of fatty acids. The elimination of pathogen was met within 6.06 h, 5.5 h, and about 10 h for the Salmonella Senftenberg W775, Enterococcus spp., and Ascaris suum, respectively in the laboratory trials. The obtained results were confirmed in full-scale tests, using 1500 m3 Kompogas® reactors, operating in MBT Plant located in Poland. Sanitization of the digestate was achieved. Furthermore, the process was stable. The pH value, suspended solids, and ammonium content remained stable at 8.5, 35%, and 3.8 g/kg, respectively. The acetic acid content was noted between almost 0.8 and over 1.1 g/kg, while the concentration of propionic acid was noted at maximum level of about 100 mg/kg. The AD conditions could positively affect the pathogen elimination. Based on these results it can be found that anaerobic digestion under thermophilic conditions results in high sanitation efficiency.

The Planning, Implementation, and Evaluation of California's Inaugural Food Waste Prevention Week.

Preventing food waste can divert food from landfills to feed people, combat climate change, preserve natural resources, and save money. In February 2017, the Nutrition Policy Institute and the Public Health Alliance of Southern California initiated a multisector collaboration among California state agencies to raise awareness about food waste. After development and distribution of a Communications Guide, Food Waste Prevention Week was launched successfully in March 2018, with official support from California's Governor, Secretary of Agriculture, Superintendent of Public Instruction, and other leaders. The multiagency shared messaging campaign was estimated to reach millions, based on unique page views via social and traditional media. In a follow-up survey, partners expressed satisfaction with Food Waste Prevention Week and interest in participating in future efforts. Organizing leaders across multiple sectors to raise awareness about food waste is possible; such efforts can contribute to driving behavioral and structural changes to reduce food waste.

Use of interaction matrices to formalise the development of conceptual models of contaminant transport in the biosphere and the translation of those conceptual models into mathematical models.

In developing models of the biosphere for use in assessing the impacts on human health and the environment of releases of contaminants from disposal facilities for solid radioactive wastes or from contaminated legacy sites, there is a need to demonstrate that the models adopted are both comprehensive and appropriate to the assessment context. To achieve this end, it is useful to develop a structured approach to conceptual model development and it is here proposed that interaction matrices (IMs) provide a suitable framework. This process can provide a conceptual model expressed in terms of either a single IM or a nested set of IMs. The focus of the work described herein is the development of a transparent approach to translating such a set of IMs into a mathematical model, which is typically expressed as a set of ordinary differential equations complemented by algebraic expressions. Some remarks are also made on appropriate approaches to obtaining numerical solutions of these equations in circumstances where simplifications of the general equations can be justified. Overall, the intent is to provide background and guidance by providing a formal basis for the process in generalised terms.

Optimization of municipal solid waste collection and transportation routes, through linear programming and geographic information system: a case study from Sanliurfa, Turkey.

Solid waste is one of the important causes of the environmental crisis that negatively impacts human health throughout the world and is fast approaching a disaster level that will pose a direct threat to human life. As with all other environmental problems, the increase in solid waste production that goes hand in hand with growing population and rising consumption has become a focus of great concern. Along with these rising levels, the investment, management and maintenance of solid waste collection and transport vehicles is seeing a continual increase in financial outlay. It is clear from the budgets of local authority solid waste management systems, 65 to 80% of which are accounted for by domestic waste, that the collection and transport of solid waste is a high-cost process and that this expenditure can be significantly reduced by the reorganisation of solid waste collection routing schedules and the minimization of collection frequency. This study demonstrates a linear programming model in order to develop an optimal routing schedule for solid waste collection and transportation, thereby reducing costs to a minimum. The neighbourhood of Veysel Karani in the Haliliye District of Sanliurfa Province, Turkey, was specifically selected for this case study, having the suitable socio-economic and demographic variables to be representative of a metropolitan urban area. Firstly, the data regarding the municipal solid waste collection and transport routes were obtained from the local authority. Analysis and verification of these data were then performed. With the field study, these data were verified on-site, and the missing data were completed. Linear programming and geographic information system (GIS) analysis were used to determine the best route. Consequently, it is concluded that it is possible to save the route by 28% with GIS analysis and 33% with linear programming analysis according to the existing municipal solid waste collection and transportation routes.

The impact of improper solid waste management to plastic pollution in Indonesian coast and marine environment.

Plastic pollution has become a major concern in Indonesian coast and marine environment today. It occurs because 14% of the solid waste (SW) components in this country is plastic, and the SW management (SWM) infrastructure and services are still limited. The objectives of this article are to discuss the improper SWM and its impact to plastic pollution in Indonesia. Ten plastic pollution studies concerning macroplastics (MaP) and microplastics (MP) were described. These studies covered 5 regions, namely Java, East Nusa Tenggara, East Kalimantan, South Sulawesi, North and Southwest Sumatera. The highest MP abundance of 37,440-38,790 particles/kg dry weight (DW) sediment was found in Jakarta Bay, followed by Wonorejo Coast in Surabaya City (414-590 MP particles/kg DW sediment). The MP has entered the food chain through bivalves and fish. Therefore, the plastic pollution which is related to population density, and inadequacy of SWM, needs urgent solution.

Work-related stress levels and musculoskeletal disorders among municipal solid waste collectors in Ankara.

BACKGROUND: Industrialization and rising standards of living have contributed to a growing amount of solid waste and consequent disposal problems. Solid waste collection is among the occupations with the highest risk for musculoskeletal disorders. OBJECTIVE: We have conducted this study to assess musculoskeletal complaints and work-related stress levels among municipal solid waste (MSW) collectors. METHODS: The subjects were all currently employed at the MSW Department of the City of Ankara, Turkey. Validated questionnaires were completed by 267 MSW collectors. Data analysis was performed using SPSS software (22.0 version). RESULTS: Upper back pain rate was 89.1% among the collectors. 47.9% of collectors reported having had upper back pain during the last 12 months and 38.7% had experienced it during the last month. 80.9% of the sample complained of shoulder pain. Wrists/hands and neck pain rates were found at rates of 78.7% and 67.8% respectively. Psychological demands, were significantly higher among MSW collectors living with moderate-severe pain. CONCLUSIONS: Ergonomics education, healthy work habits, occupational safety training and improvements in the psychosocial work environment should be considered.

Characteristics of Canteens at Elementary Schools, Upper Secondary Schools and Workplaces that Comply with Food Service Guidelines and Have a Greater Focus on Food Waste.

Policy actions to improve the nutritional environment include the provision of official food service guidelines. This study aimed to examine compliance with food service guidelines for hot meals as well as self-evaluated focus on food waste reduction across settings, i.e., elementary schools, upper secondary schools and workplaces, and different canteen characteristics. The same five criteria for hot meals were applied for all settings with regard to serving of fruit and vegetables, fish, wholegrain product and high fat meat and dairy products. A self-administered questionnaire survey was conducted as a cross-sectional study among 680 Danish canteens. Canteens having a high degree of organic food procurement were more likely to comply with the five criteria for hot meals combined (OR 2.00 (Cl 1.13,3.53)). Also, the use of organic food together with having a meal policy was associated with reported focus on food waste reduction (OR 1.91 (CI 1.12,3.25) and 1.84 (Cl 1.31,2.59), respectively). Compliance with individual criteria varied across settings with elementary schools being more likely to comply with criteria on, e.g., maximum serving of non-wholegrain products, whereas workplaces were more likely to comply with criteria on, e.g., minimum fruit and vegetable content and serving of fish. In addition, specific characteristics, e.g., serving system, were found to predict compliance with some of the criteria. These findings highlight the need to address differences in canteen characteristics when planning implementation support for both guideline and food waste reduction initiatives.
