“…In addition, in ensuring adequate growth of bacteria in anaerobic digestion, a regular supply of organic substances as a source of carbon and nutrients is important, they also require certain mineral nutrients in addition to nitrogen, Sulphur, carbon, oxygen and hydrogen. These elements are largely found in agricultural residues and wastes [6]. The duration of retaining the slurry in the digester influences the rate of digestion.…”

“…The main objective of the design is for energy production, maximizing the primary variables such as biodegradability of the materials, concentration of the International Journal of Clean Coal and Energy feed, kinetic constants, Retention time, that affects the production of the biogas is important [18]. In designing a biodigester, the total volume of digester, V T , volume of gas storage, V g , retention period, R t and the amount and type of organic waste to be digested are majorly considered according to experiment carried out by [6] [7] [41].…”

“…It is also important to be more conscious of environmental sanitization, as indiscriminate disposal of waste results in health issues and environmental disasters. The concept of waste management involving the collection of generated waste into modified tanks for recycling purpose to produce biogas, will be of great advantage to the nation's rising population [6] [7]. Furthermore, in accomplishing the sustainable developmental goal of ensuring access to affordable, reliable, sustainable and modern energy in Nigeria, rural communities with farming as a major occupation, lacking access to electricity, can be brought to lime-light through the adoption of biogas system for generation of energy for household usage.…”

“…The dependence on fuel wood for the domestic energy supply has aggravated deforestation, with annual deforestation rate estimated at 3%, which is equivalent to the loss of 410,000 hectares of forested land annually. Indoor air pollution from burning biomass in open fires, usually without chimneys is a major concern, as it results in respiratory diseases and premature deaths [2] [6]. Thus, the need for the utilization of more agricultural wastes as an alternative energy source is apparent.…”

The overdependence on crude oil in African countries warrants the need for alternative sources of energy. A 56-litre-capacity biogas digester was designed, fabricated and evaluated. Investigations were made into the production of biogas from the mixture of cow dung, swine dung and poultry dropping. Standard equations and models were used in the design of the components of the manually operated digester. The digester temperature, ambient temperature and pH were monitored during the experiment. The proximate analysis showed that volatile solid, total solid and moisture content for the mixed substrates at the initial stage were: 64.7%, 83.5% and 13.5% respectively. Similarly, at the digestion stage, the volatile solid, total solid and moisture content were: 54.1%, 22.6% and 74.4% respectively. Advancement of decomposition leads to gradual increasing pH value from 7.2 to 7.4, which indicates the stability of organic matter. The moisture content on a wet basis was initially 13.5%. This value latter increased to 74.4%. On the average, 15 kg of mixed substrates with 25 litres of impure water produced biogas within 25 days of digestion. The gas produced from mixed substrates became flammable with blue flame after 16 days of production, indicating that the ratio of methane gas generated with the three mixtures of fresh animal waste was higher than other gases produced.

“…Advancement in technology, continuous urban sprawling and improved standard of living has over the years, caused a corresponding increase on energy demand, which is largely used in powering automobile and other related machines and appliances. Energy from coal, fossil fuel and some renewable sources like solar and biomass have been widely used with fossil fuel being the most utilized among them [1,2]. Fuel is one of the major products of processed crude oil, rich in hydrocarbon content and is largely sort after for effective running of human daily activities.…”

Land farming technique was used to treat hydrocarbon contaminated soil collected from a crude oil spill sites in Edo State, Nigeria. Calibrated standard auger was used to collect soil samples from the site at depth below 30 cm. The samples were characterized and classified. Cow dung and NPK fertilizer were added as additives to complement the nutriments of the soil samples before total petroleum hydrocarbon quantification and remediation procedures. Factorial design was applied to vary the input parameters such as pH, mass of substrate, moisture content and turning times of land farming so to ascertain the optimal conditions for the procedure. The result revealed that the in-situ TPH value was 5,000 mg/kg on the average and after 90 days of treatment, the turning rate, pH, moisture content and mass of substrate had 82.79%, 4.36%, 0.48% and 0.046% contributions respectively to land farming treatment. Numerical optimization techniques applied in the optimum point for land farming input parameters to achieve predicted maximum removal of 98.60% were evaluated as pH, mass of substrate, moisture content and turning rate to be 6.01, 1 kg, 10% and 5 times in a week respectively. TPH removed at this optimum point was 97.83% reducing from 5,000 mg/kg to 645.9 kg/mg. The high coefficient of determination (r2 = 0.9865) as observed in the closeness of predicted and experimental values reflects the reliability of the model and hence, land farming practice with close attention on turning rate as revealed by this study, is recommended for TPH contaminated soil remediation.

The management of agricultural waste has become very important because the inappropriate disposal yields negative effects on the environment. The resource recovery from agricultural waste which converts waste into available resources can reduce the waste and new resource consumption. This review summarizes the 2018 researches of over three hundred scholar papers from several aspects: agricultural waste, and, waste chemical characterization, agricultural waste material, adsorption, waste energy, composting, waste biogas, agricultural waste management, and others.
