Abstract
Solid waste management (SWM) is one of the most challenging issues faced by institutions that suffer from serious pollution problems caused by the generation of large waste quantities as a results of student’s explosion. Reliable national data on waste generation and composition that will inform effective planning on waste management in Lead City University, Ibadan is absent. To help obtain this data on an institutional basis, selected source of waste generations in the university were recruited to obtain data on rate of waste generation, quantification, sorting and separation efficiency and per capita of waste. Therefore, the study's title, "Innovative approach to solid waste management in Lead City University, Ibadan: Adaptive Sanitary Landfill Technology," focused on the management of solid waste in the University. A pilot source sorting and separation was conducted at the selected twenty-seven (27) hostels being the sources of waste generation in the Lead City University, Ibadan from November 2022 to April, 2023 for collection of data on composition, generation rate and compliance level of separation of the waste. Also, experimental methods were utilized to measure the amount of Liquefied Gases (LFG) concentrations generated using the handheld Sewerin Multitec 540. Results shown that majority of the lecturers (19.79%) agreed that Open dump system practices in Lead City University, Ibadan have positive environmental impacts while majority of the students (31.25%) agreed that the best way to tackle waste problem is sorting from generation before collection and disposal. Total numbers of students living in Lead City University hostel (LCU) were 3,892 out of 13,647, of which 9,755 stayed off campus. The overall student population of Lead City University at the time of this project work is 13,647. Independence Champion and Wisdom Hall with total number of students of 548 have the highest number of waste generation per week of 677.50kg while Maintenance Hall with total number of students of 27 have the least number of waste generation per week of 68.30kg. Also, out of the five components of waste, food ruminants have highest waste generation of 1,967.70kg in all the twenty-seven (27) halls of residences in the university and Papers have the least waste generation of 961.00kg in all the twenty-seven (27) halls of residence in the university. The research also revealed that certain amount of Liquefied Gases (LFG) concentrations were measured in the morning and afternoon, addition of activated charcoal made the amount of methane (CH4) gases (LFG) increased by removing impurities such as Hydrogen Sulphide (H2S) and Carbon Dioxide (CO2) and finally, the amount of liquefied gases (LFG) generated after the addition of animal manures was higher compared to when not added. Correction results shown that the interactions are statistically significant. Conclusively, the research project aims to strengthen the inclusive waste management structural model and serve as a planning tool for establishing a cohesive, financially secure, environmental friendly, and socially inclusive university environment through sustainable waste management by constructing an indigenous adaptive sanitary landfill at LCU, Ibadan.
