Resource Potentials of Composting the Organic Wastes Stream from Municipal Solid Wastes Compositions Arising in Nigerian Cities

Abstract

The paper presented an assessment of the resource potentials of composting organic waste materials arising from the municipal solid waste stream from cities in Nigeria. Through a review of quantitative data, the composition of municipal solid waste arising within cities in Nigeria was examined in order to identify the potentials for composting organic materials from the waste stream composition. The data showed that the average majority of the waste stream was organic materials which implied high potentials for composting organic waste materials from Nigerian cities. The review also identified further potentials for composting was associated with the large population and the majority of them engaged in agriculture, as a high potential market for compost manure in Nigeria. There were more potentials derivable from the current policies of importing and supplying chemical fertilizer with huge subsidies for domestic agriculture in the country. The need to substitute these policies of chemical fertilizer with the use of compost manure implied high potentials for composting in the country. The paper also identified numerous benefits of composting in general and with particular reference to the Nigerian situation which includes, among others a reduction of the vast quantity of solid waste for final disposal, reducing air pollution and ground water leachate and also employment generation and increased income. Therefore, the paper recommended a deliberate government policy to promote composting of organic solid wastes material and marketing of compost manure to substitute the current policies of importing chemical fertilizer with subsidy for domestic agriculture as a strategy to achieve sustainable waste management in Nigeria.

Investigation of the influence of biofertilizer synthesized using microbial inoculums on the growth performance of two agricultural crops

“…Lenox et al [ 24 ] reported a cellulose concentration of 53 % and suggested that high resistant to biodegradation by sawdust was due to its high cellulose and lignin content. The initial contents of nitrogen in the sewage sludge (5.16 %), Chicken litter (4.96 %) and vegetable waste (5.9 %) were in conformity with what was presented by Harir et al [ 25 ] and Asadu et al [ 26 ] with the same organic wastes and suggested that the percentages were sufficiently high to maintain the microbial growth for biodegradation during composting. High concentration of organic matter in all the wastes sludge confirms that they are biodegradable and good substrates for production of biofertilizer.…”

Effects of Institutional Framework Lapses in Solid Waste Management; Case of Ngomongo, Nairobi, Kenya

“…NCC has unlimited illegible dumpsites, evident in the case of Ngomongo [26][27][28]. Importantly, waste recycled to reduce the pollution on the environment, provide job opportunities, as evident in developed countries, to address the challenges of SWM [16,29]. There is an institutional framework lapse in the recycling of waste, no mechanism for separating waste, no capacity at source, and the household level, no waste separation.…”

“…The actors, the public, civil society, NCC, NEMA, and ministries of environment and Natural resources and Water Resource Authority [30,31]. Indiscriminate disposal by the public shows the absence of public education on SWM focusing on critical areas, for instance, proper waste disposal, waste reduction, and environmental stewardship [29,32]. Also, insu cient institutional, nancial capacities, and management systems affect performance, restraining the interpretation of policy and legislation on SWM in practice [24,[33][34][35].…”

Profil pH dan Volatile Suspended Solids pada Proses Pengomposan Tandan Kosong Kelapa Sawit Menggunakan Pupuk Cair Organik Aktif sebagai co-Composting

“…Alternatif, TKKS dapat dijadikan bahan baku dalam proses pengomposan [5]. Pengomposan adalah proses penguraian limbah organik secara biologis dengan bantuan mikroorganisme secara aerobik menjadi zat humus [6]. Proses pengomposan dapat dipengaruhi oleh beberapa parameter seperti nutrisi, rasio C/N, ukuran bahan kompos, suhu, pH, kadar air, dan frekuensi pembalikan [7].…”
