This article poses the question on whether and how youth participation in environmental sustainability makes a difference within participatory budgets (PBs). This is a question worth asking because PBs have pursued, from the very beginning, goals of social sustainability through the inclusion of social groups that struggle to make their voices heard, as in the case of the youth. As young people show an increasing capacity to self-organise around environmental issues, a knowledge gap emerges as to the contribution that youth can give to environmental sustainability within PBs.

The 2021 edition of the Lisbon PB (2021PB) has been analysed through desk research – document analysis using the city council's website as the main source of information, and fieldwork – an organisation of one two-day workshop with 20 young students through a partnership between the local authority and the Institute of Social Sciences at the University of Lisbon. Methods were applied to retrieve findings on youth participation in environmental sustainability in the 2021PB.

The youth show a relative increase of participation in the 2021PB and emerge as a key target group in funded proposals. Convergence with student proposals suggest shared awareness on the role of youth in the pursuit of social sustainability. The success of health-related proposals confirms ownership of (young) citizens over the concept of environmental sustainability, which further relies on the various scopes of funded proposals at both city and neighbourhood levels. In the workshop, students did not stick to specific themes and struggled to connect present criticalities and future imaginaries.

Focus on one case study necessarily limits the generalisation of findings. Nevertheless, the 2021PB illuminates pathways of research on youth participation in environmental sustainability through participatory budgeting that are worth clearing in the future, such as the role of digital participation, dynamics induced by extreme events as the COVID-19 pandemic and PBs' capacity to intercept environmental activism.

Decision-makers and practitioners can take advantage of findings to acknowledge the potential of youth participation in PBs to reframe the take of environmental sustainability.

The article provides new inputs for future developments in the operationalisation of social and environmental sustainability through participatory budgeting.

This article examines original data retrieved from the 2021PB. Data analysis is backed by the literature review of key democratic challenges in social and environmental sustainability within participatory budgeting.

This study aims to identify the key factors that influence the intention and behavior of Chinese consumers toward purchasing organic food. The extended theory of planned behavior (TPB) model is adopted as the underlying theory to explore the relationship between attitudes (ATT), subjective norms (SN) and perceived behavioral control (PBC) on consumers’ intention and behavior to buy organic food. Trust (TR) and the moderating role of short food supply chain preferences (SFSCPs) were integrated to address the research gap.

Three hundred three questionnaire responses were received from organic food buyers in China using a convenience sampling method. Structural equation modeling was used to analyze the data and to examine the relationship between the various constructs.

The results demonstrated that the purchase intention (PI) of Chinese consumers correlates positively with ATT, SN, PBC and TR. Additionally, the results show that consumers’ SFSCPs positively moderate the relationship between PI and purchase behavior (PB).

The findings of this study provide valuable insights for marketers to develop compelling messages that evoke positive ATT, establish consumer TR and integrate short food supply chains to drive PB. The study can also be useful to policymakers and other supply chain participants.

An increased understanding of the factors influencing Chinese organic food consumption can contribute to promoting healthier food choices, supporting sustainable agriculture and fostering environmentally friendly consumption habits.

This research contributes to the existing pool of knowledge by incorporating TR into the conventional TPB. The study also introduces SFSCP as a moderating variable on the relationship between PI and PB.

The study aims to predict the drivers of green purchase in extended theory of planned behaviour (TPB) by investigating direct and indirect role of consumers' attitude toward green purchase along with moderating effects of green trust and willingness to pay on purchase behaviour in an emerging market.

A total of 417 useable responses were recorded from three different states of north India to resolve the issues related to demographic diversity in country by using a structured questionnaire. Structural equation modelling, mediation and moderation analyses were used to investigate the hypothesised relationships.

The research unveiled that environmental concern, subjective norm have significant direct and indirect influence on green purchase intention via attitude. Furthermore, this study also elucidates that green trust significantly moderates attitude–behaviour, and intention–behaviour relationships, whereas willingness to pay does not significantly moderate these relationships in proposed model.

This study provides interesting insights regarding consumers of emerging market toward green purchase. These insights are useful for marketers to design more focused strategies for enhancing the consumers' preferences for green products and promotion of pro-environmental behaviour in emerging markets.

The novel insights of this study are the mediating role of attitude in an emerging market in extended TPB model and exploration of the moderating role of green trust and willingness to pay premium to reduce the attitude–behaviour and intention–behaviour gaps for enhancing the consumers' preferences for green purchase.

A direct correlation exists between waste disposal, disease spread and public health. This article systematically reviewed healthcare waste and its implication for public health. This review identified and described the associations and impact of waste disposal on public health.

This paper systematically reviewed the literature on waste disposal and its implications for public health by searching Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA), PubMed, Web of Science, Scopus and ScienceDirect databases. Of a total of 1,583 studies, 59 articles were selected and reviewed.

The review revealed the spread of infectious diseases and environmental degradation as the most typical implications of improper waste disposal to public health. The impact of waste includes infectious diseases such as cholera, Hepatitis B, respiratory problems, food and metal poisoning, skin infections, and bacteremia, and environmental degradation such as land, water, and air pollution, flooding, drainage obstruction, climate change, and harm to marine and wildlife.

Infectious diseases such as cholera, hepatitis B, respiratory problems, food and metal poisoning, skin infections, bacteremia and environmental degradation such as land, water, and air pollution, flooding, drainage obstruction, climate change, and harm to marine and wildlife are some of the public impacts of improper waste disposal.

Healthcare industry waste is a significant waste that can harm the environment and public health if not properly collected, stored, treated, managed and disposed of. There is a need for knowledge and skills applicable to proper healthcare waste disposal and management. Policies must be developed to implement appropriate waste management to prevent public health threats.

The purpose of this paper is to study and analyze the effects of fly ash (FA) as a mineral admixture on compressive strength (CS), carbonation resistance and corrosion resistance of reinforced concrete (RC). In addition, the utilization of inexpensive and abundantly available FA as a cement replacement in concrete has several benefits including reduced OPC usage and elimination of the FA disposal problem.

Reinforcement corrosion and carbonation significantly affect the strength and durability of the RC structures. Also, the utilization of FA as green corrosion inhibitors, which are nontoxic and environmentally friendly alternatives. This review discusses the effects of FA on the mechanical characteristics of concrete. Also, this review analyzes the impact of FA as a partial replacement of cement in concrete and its effect on the depth of carbonation in concrete elements and the corrosion rate of embedded steel as well as the chemical composition and microstructure (X-ray diffraction analysis and scanning electron microscopy) of FA concrete were also reviewed.

This review provides a clear analysis of the available study, providing a thorough overview of the current state of knowledge on this topic. Regarding concrete CS, the findings indicate that the incorporation of FA often leads to a loss in early-age strength. However, as the curing period increased, the strength of fly ash concrete (FAC) increased with or even surpassed that of conventional concrete. Analysis of the accelerated carbonation test revealed that incorporating FA into the concrete mix led to a shallower carbonation depth and slower diffusion of carbon dioxide (CO₂) into the concrete. Furthermore, the half-cell potential test shows that the inclusion of FA increases the durability of RC by slowing the rate of steel-reinforcement corrosion.

This systematic review analyzes a wide range of existing studies on the topic, providing a comprehensive overview of the research conducted so far. This review intends to critically assess the enhancements in mechanical and durability attributes (such as CS, carbonation and corrosion resistance) of FAC and FA-RC. This systematic review has practical implications for the construction and engineering industries. This can support engineers and designers in making informed decisions regarding the use of FA in concrete mixtures, considering both its benefits and potential drawbacks.

Sustainable consumption is an important topic for different industries, including the fashion industry. Despite a favourable attitude of consumers towards sustainable products in the fashion industry, the actual purchase by the consumers is limited. Thus, the present study examines sustainable consumption using the theory of planned behaviour (TPB). The purpose of this paper is to study the mediating impact of strategies of justification of unethical behaviour on the gap-based relationship between a purchase intention and a purchase decision for a consumer in a sustainable clothing context.

For the study, the primary data from 229 graduate-level fashion students enrolled in universities across India has been analyzed with the help of structural equation modelling.

The study results have proven that attitudes and subjective norms can positively affect purchase intentions when it comes to purchase of the environmentally sustainable products. Further, economic rationality (ER) and government dependency (GD) partially mediate the purchase intention–behaviour gap of the justification strategies for unethical behaviour.

The results would be helpful in implementing sustainable clothing consumption among Indian consumers. The study would be beneficial for industry professionals, export houses and scholars to discover possible reasons which can lead to the widening of the intention–behaviour gap when it comes to the purchase of the sustainable clothing consumption for Indian consumers. Critical implications for marketers from the present research assert that ER and GD are important factors that could increase the purchase intention of young consumers towards sustainable clothing.

The results of the study contribute to the existing literature in a novel way by adding justification strategies for unethical behaviour to the TPB model. This study is innovative as it adds new constructs to the TPB model by including the three justification strategies that people use for unethical consumption behaviour (ER, economic development and GD) to gain insight into why a purchase intention–behaviour gap exists for sustainable clothing.

This study aims to analyze the factors affecting tea-producing farmers' intention to use e-commerce exchanges (ECEs) to sell their products, combining the technology acceptance model (TAM) theory and barrier factors.

The authors use the generalized structural equation modeling (GSEM) to analyze the intermediate model that is built on TAM.

Research results show that perceived usefulness (PU) and perceived ease of use (PEU) significantly influence farmers' intention to use ECEs to sell their products. However, knowledge and information barriers hinder farmers' intention to use such ECEs.

Encouraging farmers to use ECEs is the most helpful solution for agricultural economic development in the context of the Covid-19 pandemic.

From an academic perspective, this is the first study that combines the TAM theory of Davis (1989) and barrier factors to analyze farmers' intention to use ECEs. The findings are valuable references for policymakers to propose strategies for agricultural economic development during the current pandemic. At the same time, the empirical results obtained from this study provide good orientations for agricultural economic development 4.0 in the future.

This study aims to investigate the determinants of household behavioural intention towards household reducing, reusing and recycling behaviour of food waste management.

The data were collected from 670 households in Malaysia and analysed by using the partial least square method.

The findings reveal that motivation to participate, ability to participate and perceived benefits are the crucial factors that significantly influence households’ attitudes. Household attitude has a significant impact on household behavioural intention, whilst social influence and perceived behavioural control are not associated with it. Government support is positively related to perceived behavioural control. The result also indicates that household behavioural intention has a significant impact on household reducing, reusing and recycling behaviour.

The participants of this study were involved in home planning and food preparation in Malaysia. The individuals in charge of the household might have more awareness of food planning and waste control. Thus, it is recommended to adopt findings from other countries and learn from the experience of the local and international communities.

The households’ behavioural intentions can lead to the reducing, reusing and recycling behaviour of food waste management. The government policy mechanisms and households’ awareness can work effectively against food waste reduction because evaluations of the food waste programme were found to be scarce.

Food insecurity is one of the major social problems. Many people are not aware of the food waste impacts and consequences; thus, motivation, knowledge and information should be provided to the consumer through forums and campaigns.

The findings contribute to new insights of household behavioural intention towards food waste reduction management by assessing the determinants of household attitude and government support for food waste reduction management programmes towards household reducing, reusing and recycling behaviours.

In this study, an attempt has been made to collect the research that has been done on the construction and design of the H₂O₂ sensor. So far, many efforts have been made to quickly and sensitively determine H₂O₂ concentration based on different analytical principles. In this study, the importance of H₂O₂, its applications in various industries, especially the food industry, and the importance of measuring it with different techniques, especially portable sensors and on-site analysis, have been investigated and studied.

Hydrogen peroxide (H₂O₂) is a very simple molecule in nature, but due to its strong oxidizing and reducing properties, it has been widely used in the pharmaceutical, medical, environmental, mining, textile, paper, food production and chemical industries. Sensitive, rapid and continuous detection of H₂O₂ is of great importance in many systems for product quality control, health care, medical diagnostics, food safety and environmental protection.

Various methods have been developed and applied for the analysis of H₂O₂, such as fluorescence, colorimetry and electrochemistry, among them, the electrochemical technique due to its advantages in simple instrumentation, easy miniaturization, sensitivity and selectivity.

Monitoring the H₂O₂ concentration level is of practical importance for academic and industrial purposes. Edible oils are prone to oxidation during processing and storage, which may adversely affect oil quality and human health. Determination of peroxide value (PV) of edible oils is essential because PV is one of the most common quality parameters for monitoring lipid oxidation and oil quality control. The development of cheap, simple, fast, sensitive and selective H₂O₂ sensors is essential.

The purpose of this study is to explore Generation Z (Gen Z) consumers’ sustainable consumption behaviors at a university campus by examining various antecedent and moderating influencers of their sustainable consumption behaviors.

A quantitative research methodology is used in this study. A structured questionnaire was administered (n = 279) to young college students (Gen Z consumers in the context of this study) enrolled at a large state university in the USA. The structural equation model was used to test the hypothesized relationships in the conceptualized model.

Study findings show that social responsibility (feelings, engagement and expectations) and external incentives (material and social) positively influence Gen Z consumers’ sustainability interests, which in turn influences their sustainable consumption behaviors (actions). Collectivist cultural values did not appear to have any statistically significant effect on Gen Z consumers’ sustainable consumption interests. Moreover, learned helplessness, perceived barriers and the awareness of the consequences of sustainability consumption actions did not have any significant moderating effect on Gen Z consumers’ sustainable consumption behavior.

The questionnaire was only sent to students majoring in business degrees, which may limit the generalizability of this study to broader Gen Z consumer populations. Expanding this study to include non-business students may be valuable as a next step. Replicating this study in different cultural environments of international countries could enhance the relationships identified in this study.

Consumer social responsibility education along with material and social incentives will encourage Gen Z consumers’ participation in sustainable behaviors at college campuses.

This research provides valuable insights into understanding the importance of consumer social responsibility and external incentives in influencing Gen Z consumers’ sustainable consumption intentions and behaviors. Accordingly, consumer social responsibility education and incentive programs need to be developed to encourage the participation of Gen Z consumers in sustainable consumption.
