WASTE MANAGEMENT

Effective waste management remains a critical challenge in many urban and rural communities, particularly in developing countries where improper disposal contributes to environmental pollution and public health risks. This project focuses on the design and fabrication of a waste segregation system aimed at improving the sorting of municipal solid waste at the source. The system is engineered to automatically separate waste materials into distinct categories such as biodegradable, non-biodegradable, and recyclable components using a combination of sensors, mechanical components, and control mechanisms.
The design incorporates affordable and locally available materials to ensure cost-effectiveness and ease of replication. Key components include a conveyor mechanism, sensing units for material identification, and sorting bins for categorized waste collection. The fabrication process involved assembling the mechanical framework, integrating electronic control systems, and testing the functionality of the system under different waste conditions.
Performance evaluation of the system demonstrated its ability to accurately segregate waste with improved efficiency compared to manual sorting methods. The results indicate that the system can significantly reduce human effort, minimize environmental hazards, and enhance recycling processes. This study concludes that the developed waste segregation system is a practical and sustainable solution for improving waste management practices, and it holds potential for adoption in households, institutions, and small-scale industries.

This study was on knowledge and attitude of uniben undergraduates towards plastic waste pollution and control. Three research questions were raised and answered during the study using frequencies and percentages. The survey research design as adopted for this study; this is because the data is collected from a sample population with specific characteristics. The opulation of the study was 43,679 Students. It comprises of the 15 faculties of the University of Benin. Out of this population two hundred and forty (240) sample was selected from the total population using randomly sampling technique. The instrument used to collect data for the study was ten items self-structured questionnaire. The instrument for the data collection was personally administered by the researcher to the respondents. The researcher explained to the respondents how to indicate their views on each item. On the basis of the findings made in the study, it can be concluded that University of Benin undergraduates possess high levels of knowledge about plastic waste pollution as well as plastic waste management and control. The researcher recommends that University of Benin should incorporate plastic waste pollution and management topics into the General Studies (GST) curriculum to strengthen students’ environmental knowledge.

This study examined the impact of place-based learning on knowledge andattitude towards waste management among university of Benin students. Tworesearch questions were raised to guide the study with two hypotheses formulated 12 to guide this study as well. The quasi experimental research design was adopted for this study andthepurposive sampling technique was used to select 50 (fifty) undergraduate students in the Department of Health, Safety and Environmental Education. Data was collected from the 50 respondents using an open ended questionnaire with twenty(20) items. The data collected was analyzed and interpreted using descriptivestatistics. Based on the data collected and analyzed, it was discovered that that place-based learning does have a significant impact on students' knowledge of waste management at the University of Benin. However, fromthe hypotheses tested it was further observed that that place-based learning does not haveasignificant impact on students' attitudes toward waste management at theUniversity of Benin. It was therefore concluded that it is crucial to incorporateexperiential learning strategies, like PBL, into environmental education programs in order to enhance students' comprehension of waste management. PBLprograms should, however, be maintained over time and supplementedbycommunity involvement, policy backing, and infrastructure advancements inorder to produce significant attitudinal change. Long-term therapies, behavioral reinforcement techniques, and outside variables that affect students' attitudes about trash management should all be investigated in future studies. PBLhas theability to support long-term behavioral change in sustainable waste management methods in addition to information development by encouraging ongoingengagement and practical implementation. It was recommended that universities should incorporate sustained PBL activities into their environmental educationcurricula. Long-term engagement in real-world waste management projects, suchas recycling programs and waste audits, can reinforce knowledge and graduallyinfluence students’ attitudes. Also partnerships between universities, local 13 governments, and environmental organizations should be encouraged to providestudents with opportunities for active participation in community-based wastemanagement initiatives.
