“…Estimates for biogas potential in Nigeria, the most populous country in Africa, is 6.8 million cubic meters per day from animal manure [37] and 913,440 tonnes of methane from MSW, equivalent to 482 MW of electricity [38]. Furthermore, Giwa et al [39] estimated that up to 171 TJ of energy could be generated from biogas by 2030 in Nigeria.…”

Many African countries have vast biomass resources that could serve as feedstock for methane production through the adoption of commercial biogas plants. However, due to many inhibiting factors, these resources are under-utilised. This article reviews commercial biogas systems that treat organic waste from municipalities, large livestock farms, large plantations/crop farms, food/beverage production facilities, and other industries, to identify essential lessons which African countries could use to develop/disseminate such biogas systems. The review identified the critical barriers to commercial biogas development to be high initial capital costs, weak environmental policies, poor institutional framework, poor infrastructure and a general lack of willpower to implement renewable energy policies and set challenging targets. In African countries where feed-in-tariffs, quota obligations and competitive bidding programmes have been instituted, implementation has been poor, and most state-owned utilities have been unsupportive. Using knowledge from more experienced countries such as Germany and China, some key lessons have were identified. Among the key lessons is the need to institute and enforce environmental management policies to ensure that waste from medium and large livestock farms and industries are not disposed of indiscriminately, a tool China has recently used to promote commercial biogas plants to a high degree of success.

“…More so, in a closed-loop and resource-security agendas that undoubtedly sits behind the bioeconomy aspirations now being voiced by many schools of thought in many countries and regions of the so fast technologically advancing world. This is the foremost reason that many countries, including international agencies at large, are working towards ensuring sustainable development [54].…”

“…Due to the nature of the molecule(s) as a novel commodity for many interesting natural and manufactured products [26][27][28][29], a modern bioeconomy [30][31][32][33] is not simply a rerun of former ones.

A brief review has been herein done of technologies involved in the exploitation of lignin, in order to provide an introduction to the subject from the perspective of a fast technologically advancing economy. Lignocellulosic materials and biomass have historically been utilised from since time memorial, but a new conversation is emerging on the role of these materials in modern bioeconomies. This new discourse needs to help us understand how technologies for managing and processing lignocellulosic materials both as biosynthetic moieties, biogenic wastes or simply renewable biopolymer-both established and novel-should be deployed and integrated (or not) to meet developmental requirements of the sustainability paradigm. The world is caught in the middle of green technology advocating for more and more focus on renewable sources of manufacturing raw materials and that of the molecularly imprinted/synthesised or genetically engineered ones. The utilisation of lignins (from renewable sources) in both the industry as the base for the formulation of ionic liquids (with yet a wider industrial applications), and also is a potential scaffold material for functionally modified imprinted polymers (LCIPS) for the selective recovery of base metals and gold, respectively, evidently incorporates the bioeconomy aspirations.

“…A theoretical estimate of methane emissions from both livestock manure in Nigeria and municipal solid waste deposits in some of the country's major cities have been provided [5]. Ten-year data obtained from the United Nations Food and Agricultural Organization (FAO) was used to estimate the methane emissions from animal wastes using a mathematical approach developed by the Intergovernmental Panel on Climate Change (IPCC).The result of the study shows that Onitsha (one of the commercial cities in the study area) is the second to the highest in statistical MEP amongst the South-Eastern mega cities in Nigeria.…”

The need for improved livestock waste management in developing countries has been emphasized by various researchers. Consideration has been given globally to advocacy for a transition from fossil energy system to Renewable Energy (RE), based on several socio-economic and environmental advantages. Green House Gas (GHG) from agricultural sector of Anambra State, with appropriate waste management strategy such as Anaerobic Digestion (AD) will definitely mitigate Methane emission hazards and will as well supply the much needed energy for domestic and industrial uses. An investigation was carried out in this study to estimate the Methane Emission Potential (MEP) of the study area as a result of poor livestock waste management system practiced in the area. This was achieved by incorporating Geographical Information System (GIS) capability to the Methane estimation. The result of the study shows that two Local Government Areas (LGA)
