In order to meet the growing demand for energy and to reduce the dependency on non-renewable energy sources, a renewable alternative energy source is needed. For decades, the development of renewable energy has been performed to meet a qualified source for alternative energy, including biomass, solar, geothermal, hydropower, sea and wind. One of promising form of renewable energy is biogas because it can be derived from evergreen feedstock that available widely. It even can use animal waste, agricultural waste, industrial waste, food waste as it raw materials, thus supporting clean and sustainable energy. Biogas is a form of gaseous bioenergy produced from the decomposition of organic matter or biomass by methanogenic bacteria in an anaerobic system. Research has been conducted to find the best raw materials as the source for biogas production. Here we will discuss type of natural feedstock that have been used as the raw materials for biogas production. Several type of raw materials including natural feedstock and waste were discussed to give a glimpse of sustainability in the generation of this biogas energy.

In this study, oil was extracted from coconut. The extracted oil was used to produce biodiesel and the oil and the biodiesel produced were characterised. Biodiesel fuels are alternative diesel fuels usually obtained from renewable sources, mainly, vegetable and animal oils. Oil was extracted from coconuts bought from a local market in Wukari Taraba State, Nigeria, by means of the solvent method. The extracted coconut oil was then characterized. This showed that the coconut oil has a density of 0.91 g, viscosity of 23 mm2/s, saponification value of 191 mg KOH/g, iodine value of 10 mgl2/g, acid value 1of 4.0 mg KOH/g and flash point of 266 °C. The biodiesel of the oil was produced using a transesterification process. The biodiesel was also characterized. Results obtained showed that the biodiesel has a density of 0.89 g, viscosity of 2.83 mm2/s, acid value of 0.18 mg KOH/g, saponification value of 91 mg KOH/g, iodine value of 8 mgl2/g, acid value of 0.18 mg KOH/g and flash point of 110 °C. The physicochemical properties of the biodiesel produce from coconut oil is comparable with that of standard biodiesel in the range of ASTM specifications.

As a consequence of the intended rise in the volume of the biodiesel produced by the member states of the European Union, predominantly from rapeseeds and sunflower seeds, the quantity of the by-products being generated, e.g. glycerol, rapeseed/sunflower seed straw and rapeseed/sunflower seed meal, will increase dramatically. It is therefore recommendable to find effective methods for their processing or utilization in order to reduce the costs of biodiesel production without polluting the environment by excessive wastes. As the utilization of glycerol has often been addressed in the literature1, the aim of our study is to describe the potentiality for utilizing the solid by-products of biodiesel production, namely rapeseed/sunflower straw and rapeseed/ sunflower seed meal.
