Solid Waste Segregation

Municipal solid waste management is a huge challenge specially in the developing countries. The first and fundamental step to solve the problem of municipal solid waste management is by waste segregation at source and separate collection of waste, which will help to recover recyclable materials and reduce the amount of waste that needs to be disposed at the dumpsite or landfill site. In Nepal, waste segregation at source is mandated by law but the government is not able to implement it successfully. This paper assesses the willingness of the households to practice waste segregation in future if the government enforces the law and various factors that influences the practice. Data was collected from 401 households which was selected using stratified sampling technique from all the municipal wards, the lowest administrative units in Nepal. The finding shows that about 67% of the respondents are willing to segregate waste in future if the government enforces the law. Logit regression model was employed to identify the factors that influence waste segregation practice. The significant variables found from this study are environmental awareness, waste collection service, willingness to pay, make compost, and segregated waste for a week variables, which are statistically significant at 1% level of significance. Income variable is significant at 5% level of significance and gender variable is significant at 10% level of significance. It is recommended that the concerned stakeholders should educate the households on the importance of waste segregation and consider these traits of households before enforcing the law.

Fast population, rapidly changing lifestyle, great urbanization along with aggressive economic development and the rapid changes in consumption rate have accelerated the daily generation and volume rate of municipal solid wastes. Efficient solid waste management has become one of the daunting national challenges, typically in developing countries, including Malaysia, to cope with the solutions for many serious environmental problems. The main purpose of this research is to examine the moderating effect of environmental education in relationships between households' attitude, perceived behavioural control and subjective norm with waste segregation-at-source behaviour. The subject of this research was households who are living in Putrajaya and the sample was selected via multistage sampling and systematic sampling method. It was quantitative research by distributing a self-administrative questionnaire. The measurements were adapted from different sources to examine participants' attitude, perceived behavioural control, subjective norm and environmental education with waste segregation-at-source behaviour. The results reveal that environmental education does moderate the relationships between attitude and perceived behavioural control with waste segregation-at-source behaviour positively. However, environmental education does not moderate the relationship between subjective norm with waste segregation-at-source behaviour positively. The findings provide an insight particularly for the local pro-environmental groups on factors that they should consider in developing pro-environmental policies. Furthermore, future research recommended using the online questionnaire in a bid to further improve the respond's rate and be more cost-effective in various aspects.

This aim of this paper is to analyse descriptively the attitude, descriptive norm, injunctive norm, and environmental knowledge in the research scope of the intention to practise solid waste segregation-at-source. 400 respondents living in the townships of the nine districts of Selangor, namely Sabak Bernam, Ulu Selangor, Kuala Selangor, Gombak, Ulu Langat, Petaling, Klang, Kuala Langat, and Sepang, were employed via a multistage sampling method to carry out this research. A self-administered bilingual questionnaire was used to collect quantified research data among respondents in order to examine their intention to practise solid waste segregation-at-source in daily routine. The descriptive analysis of the current quantitative data was then analysed using IBM SPSS Statistics Version 26.0. The results of the descriptive investigation inferred that, overall, the Selangor households surveyed were perceived to have a favourable attitude, a high level of intention to practise solid waste segregation-at-source and environmental knowledge but moderately influenced by the descriptive norm and injunctive norm throughout the research. The present research has played a significant role in enriching the existing scarce and limited Malaysian literature on the intention to practise the solid waste segregation-at-source.

It is common to see trash or wastes littering roads, streets, canals and even our own yards. Despite national laws and local ordinances on waste management, most communities are still not concerned about this issue. Unconcerned about the menace a

The environment is increasingly under threat, especially when it comes to the serious problem of solid waste. It has become a challenging burden in most developing countries, including Malaysia. The aim of this research was to assess the levels of attitude, descriptive norm, injunctive norm, and intention to practise solid waste segregation-at-source, as well as to investigate their interrelationships with the intention to practise solid waste segregation-at-source. 400 households in townships in nine districts in Selangor have been selected using a multi-stage sampling method. The present research has shown that a large group of households surveyed perceived a favourable attitude and a high level of intention to practise solid waste segregation-at-source. The results also revealed that the descriptive norm and the injunctive norm have a positive relationship with the intention to practise solid waste segregation-at-source. The research concludes with policy implications as well as recommendations for future directions of research.

Solid waste generation in Malaysia is one of the challenging environmental issues which are often neglected by local households. The main purpose of this research is to ascertain the mediating effect of environmental concerns (i.e., egoistic, altruistic, and biospheric concerns) between households' descriptive norm and injunctive norm to practice the segregation-at-source of solid waste. A total of 400 residents living in townships in nine districts in the state of Selangor were selected via a multistage sampling method. A self-administrated bilingual questionnaire was used to collect the research data. As for the mediation test, the present research found that egoistic concern and altruistic concern mediated the significant relationship between injunctive norm and intention to practice the segregation-at-source of solid waste among the households in Selangor. The present research concludes with research implications and provides several avenues for future research in order to create a comprehensive understanding of the segregation-at-source of solid waste policy among Malaysian citizens.

A major problem with our present society is the solid waste management, as it disturbs both the human health and affects the environment. Monitoring of those wastes is one of the major problems of the present. The traditional method of solving this issue is by making use of huge trash cans in public places and utilizing the role of human scavengers, which is time consuming in nature. This paper proposes an advanced method in which waste management is automated. This project aims at making use of a wheeled bot, which detects the wastes and collects in the trash can provided with the bot, with the help of a digital camera, in a similar way how human scavengers collect wastes and separates the useful items if any mixed with the wastes. The bot also segregates the useful items from the wastes with the aid of IoT. The penultimate aim in making this project is to promote smart city concept and to reduce the diseases that spread due to accumulation of wastes in public places and to improve sanitation.

The grade of the environment is gradually declining especially when it comes to the severe problem of solid waste. It has become a challenging burden for many large metropolitan heterogeneous areas in most of the developing countries. The main purpose of this research is to investigate the relationship between households’ attitude, descriptive norm and injunctive norm with intention to practise solid waste segregation-at-source and to ascertain the mediating effect of environmental concern and moderating effect of environmental knowledge between households’ attitude, descriptive norm and injunctive norm with intention to practise solid waste segregation-at-source. The instrument is then validated from four main aspects: face validity, content validity, convergent validity and discriminant validity. After the validation process, the pre-test of this research instrument is conducted among 30 Malaysian households. All the statements have been adjusted after reliability and validity tes...
