PROSPECT OF SUSTAINABLE ENERGY (BIOGAS) GENERATION IN THE UNIVERSITY OF UYO

Thesis Overview

<p> </p><p><strong>1.1 &nbsp; &nbsp; &nbsp; Background to the Study</strong></p><p>In contemporary times, increasing concern for environmental health, eco-friendly waste management and sustainable energy production constitute the focus of many <a target="_blank" rel="nofollow" href="https://www.modishproject.com/efficiency-and-effectiveness-of-security-agencies-in-nigeria-ports/">trade bodies, regulatory agencies</a>, states and countries of the world. Energy efficiency and renewable energy are two key components of sustainable energy that provide significant environmental benefits. This environmental gain is usually seen in terms of ‘sustainable development’; which is a term that is now commonplace in a number of waste management, energy generation and rural development plans (Duerr et al.,2007).</p><p>Energy, which is a driver of economic growth, is obtained from various primary sources that are not limited to coal, petroleum, nuclear but also incorporates renewable sources from wind, solar and biomass. Of all these, the most widely used source is the non-renewable fossil fuel which account for more than 80% of global primary energy consumption (Awwad et al., 2007, cited in Oyedepo, 2012), with its attendant environmental pollution.</p><p>To date, there is global energy crisis as a consequence of declining quantity of fossil fuel coupled with the unprecedented rising crude oil prices. The crisis demands greater attention to alternative energy sources and upgrading of existing technologies. Hence it is critical now not only to focus on sustained economic use of the existing limited resources but to identify new technologies and renewable resources that have the potential to carter for the increasing energy demand in addition to possessing other positive attributes such as being sustainable, globally available, cheap and easy to exploit. Such technologies should Have the capacity to positively contribute towards actualization of the United Nation’s Millennium Development Goals, MDG (B-Africa. 2008, UN. 2008).</p><p>Nigeria is not left out from such immense dependence on fossil fuel. A country endowed with primary energy resource with a record of the world’s tenth largest reserves of crude oil estimated to be about 36 billion barrels (about 4.896 billion tonnes) of oil equivalent in 2006 (Dayo, 2008), is yet to attain sustainable development with resultant effect on the environment.</p><p>As Nigeria is a populated country in Africa, it has significant resources of organic waste. Rapid urbanization, industrialization and agricultural activities have created environmental concern such as environmental pollution from <a target="_blank" rel="nofollow" href="https://www.modishproject.com/a-statistical-analysis-on-the-effect-of-industrial-training-on-hnd1-students/">municipal, industrial and agro-allied waste</a>. Waste, which is an output of any operational system has continue to grow with more attention to an effective waste disposal management system. No doubt, there has been infinitesimal prospect into waste to energy technology(WTE) as a waste management strategy (Akhator et al, 2016, Tsunato et al.,2015; Agbo et al., 2011; Amber et al.,2012; Suberu et al.,2012). This is majorly the focus of this research. The study underscores this prospect in one of the higher institutions of learning in the country, from a paradigm shift on clean and healthy waste disposal method towards a sustainable approach. This approach embodies the concept of the four R’s, such as reduce, re-use, recycle and renewable energy which has generally been accepted as a useful principle for waste handling (Kothari, et al. 2010).</p><p>Waste-to-energy technology has been a viable waste management strategy in establishing sustainable waste disposal, delivery renewable energy and providing better end products such as biogas generation and farm manure in comparison to other disposal methods (landfills or incineration). Hence biogas, a waste-to-energy strategy, do not only provide renewable energy in the <a target="_blank" rel="nofollow" href="https://www.modishproject.com/evaluation-of-gasoline-generator-modified-for-biogas-utilization/">form of heat, electricity, fuel and methane gas</a>&nbsp;for cooking from low/ negative value organic waste (Kothari, et al. 2010), but also minimizes environment pollution by anaerobic digestion process. To this end, this research examines the generation of energy from an organic waste known as Biogas. The interest in such renewable energy is driven by the rapidly shrinking reserve of fossil fuel due to increasing demand for primary energy, fuel price spikes, global warming- from flaring and greenhouse gas emission; and most importantly the availability of organic waste.</p> <br><p></p>
