Solid waste quantification and characterization in university of Nigeria, Nsukka campus, and recommendations for sustainable management

Abstract

Quantification and characterization of municipal solid waste are the bases for a proper solid waste management planning but the needed collection, transportation, characterization and disposal are grossly under-investigated and scarcely implemented in Nigerian Universities. This study, therefore, quantified and characterized the waste generated in the university of Nigeria, Nsukka campus using ASTM D5231-92 method, and recommended possible integrated solid waste management strategies for a sustainable management of the waste. The average daily solid waste generation in the university was estimated to be 2,218.66kg during the 6-month study period from 24 th February to 18 th August in 2017/2018 academic session with organic and polythene representing the largest portion at 32.36% and 34.29%, respectively. Glass/bottle, textiles/leather, rubber, wood, e-waste, sanitary, medical, polystyrene food pack and metal wastes represented 0.97%, 2.69%, 0.28%, 0.82%, 0.98%, 2.16%, 0.16%, 1.04% and 1.67%, respectively. The campus has a per capita solid waste generation rate of about 0.06kg/ day. About 96.58% of the total waste is recyclable, and has about 51.85% biomass potential. Analysis of variance showed that differently dominated areas of the campus have different quantities and compositions of wastes mainly due to significant variation of organic and polythene components across the differently dominated areas. The barriers against effective solid waste management and recommendations for integrated solid waste management strategies were made to include solid waste generation reduction, re-usage, recycling, composting, and proper training and provision of incentive and other fiscal policies.

Assessment of municipal solid waste management system in Lae City, Papua New Guinea in the context of sustainable development

“…With minimal economic instruments available to this industry, it is difficult to facilitate and implement the programs and systems to ensure sustainable and minimized waste production. By helping all stakeholders understand the relationships and interlinkages between poor waste management and adverse health outcomes to the population, coupled with a life cycle assessment of important waste systems, the investment can be more compelling in supporting the waste Ugwu et al (2020) industry (Ziraba et al 2016). Where possible, governments should engage the support of international partners in establishing the foundational frameworks for LC's solid waste management practices.…”

“…Many studies concerning the sustainable MSW management of developing cities have been undertaken by various authors such as solid waste characterization and quantification of Nigeria city was performed using ASTM D5231-92 method and the barriers against effective MSW management and recommendations for integrated MSW management strategies to include solid waste generation reduction, recycling, reuse, composting, and proper training and provision of incentive and other fiscal policies (Ugwu et al 2020). Similarly, the complete evaluation resulted from an integrated MSW management strategy in Turkey in the development of strategies (behavioural, structural, and managerial) to decrease the solid waste generation rate, increase the recyclable material collection rate, and initiate compost activities (Berkun et al 2011).…”

A Partial Environmental Engineering Management Study of Open Dump Site and Its Impact on Land and Water

“…The changes that could be experienced can result to a major source of portable water pollution making these water sources unfit for human consumption. Unfortunately, Nigeria has been noted as one of the developing countries having serious challenges of managing their increasing solid waste generation [16] It will not be out of place to intensify wake up calls to change the narrative in these economies and any town where inadequate dumpsites management are treated with levity. Unfortunately, some of these areas are often converted to farmlands with less befitting treatment if any at all.…”

Evsel katı atık oluşum miktarlarının küresel ve yerel mekânsal otokorelasyon yöntemleri ile incelenmesi

“…Kullanım ömrü tükenmiş ve kullanıcısı tarafından atıl olarak değerlendirilen materyal veya objelere atık denilmektedir [1]. Katı atıkların büyük bir kısmı ise insanların günlük aktiviteleri sonucu oluşan ve içerik bakımından çok çeşitli olan, evsel katı atıklardır [1].…”

“…Kullanım ömrü tükenmiş ve kullanıcısı tarafından atıl olarak değerlendirilen materyal veya objelere atık denilmektedir [1]. Katı atıkların büyük bir kısmı ise insanların günlük aktiviteleri sonucu oluşan ve içerik bakımından çok çeşitli olan, evsel katı atıklardır [1]. Avrupa Birliğinde oluşan toplam atıkların sadece yaklaşık %9'unu evsel kaynaklı oluşan atıkların oluşturmasına rağmen gelecek 5 yılda evsel katı atık miktarının iki katı artacağı tahmin edilmektedir [2].…”
