“…Tap water was added to each digester to improve the moisture content and enhance the process of digestion except for treatments T6 and T7 in which inoculums were added in a 1:1 ratio with water [13]. According to a recommendation made by Ituen et al [14] and Rai [15], optimum biogas is produced when a total solid (TS) of 8% is obtained in the fermentation slurry. So the feed stocks were mixed with tap water to get 8% TS solution.…”

IntroductionJusticia schimperiana (Hochst.ex A. Nees) T. Anders is a perennial herb or shrub with many branched stems, up to 0.8-3 m tall with slightly unpleasant smell. Leaves blade up to 15-24 × 8-12 cm, ovateelliptic, broadest near the base, base cuneate to attenuate entire along the margins, apex acuminate, pubescent along veins on both surfaces, or rarely pubescent all over both surfaces; lateral veins 5-9 pairs; petiole up to 10-40 mm long; pubescent with non-glandular hairs to nearly glabrous [1,2]. The Ethiopian government under NBPE in collaboration with the Netherland Development Organization (SNV Ethiopia), an international NGO, has embarked on an ambitious biogas program to construct biogas plants to address the rural energy crisis and indoor pollution caused by the burning of traditional biomass. The first phase program is being implemented in Amhara, SNNPRS, Oromia and Tigray regions [9]. However, the only targeted raw material being used for the biogas production is manure which has lower energy content than green shrubs since animals that produce it have already digested the substrate [10,11]. So, co-digestion using leaves of JS could be important for sustainable and uniform feeding of the digesters and therefore relatively higher biogas production and slurry use. It may also open the opportunity for those households who have less than four heads of cattle to be included in the program [12]. This study is

“…The biogas production has potential value in the households as it allows them to operate under optimal conditions (Ituen et al, 2018). From the firewood and kerosene equivalent of the produced biogas, biogas produced can be used to efficiently replace firewood and kerosene in household cooking and lighting (Silva et al, 2017).…”

The article evaluates the biogas as the alternative energy source useful for contributing to the future. Biogas has been found to offer one of the best alternatives due to its economic significance as well as the improved sustainable development through reduced greenhouse gas emissions. The work investigates the production of biogas as an alternative source of energy while outlining its significance in reducing the issues of power energy as well as environmental pollution. The authors analysed the level of bioenergy development in Kazakhstan and around the globe. They revealed that Brazil, China, USA, India and Germany are leaders of bioenergy production in the world. According to the authors, development of bioenergy in Kazakhstan is related to commissioning of new bioenergy stations and supporting sources of renewable energy by government mechanisms. In the case of Kazakhstan, the authors highlighted the fact that existing biogas plants are only used for processing municipal solid waste in urban landfills despite being a major producer of agricultural products.

“…The following ratios were the five treatments used in the study; D-1 (100% TSW), D-2 (75% TSW: 25% CD), D-3 (50% TSW: 50% CD), D-4 (25% TSW: 75% CD) and D-5 (100% CD) on the basis of (w/w)%. The amount of total solid (TS) of each treatment was kept constant at 100 g and the amount of water added was as recommended by Ituen et al [14], so that the TS in the digester is 8%. Each treatment was run in triplicate and 100 ml of inoculum were added to kick-up the reaction.…”

The present study characterized the physical property, total solids (TS), volatile solids (VS) and Carbon to Nitrogen ratio (C/N ratio) of tannery solid waste (TSW). Five different combinations with or without cow dung (CD) were assessed for their biogas production suitability in triplicate batch digesters (D-1, D-2, D-3, D-4, and D-5) with a total volume of 2.8L. The results showed that TS, VS and C/N ratio of wastes were 56.37%, 76.34% and 29.05%, respectively. The results also suggested that the highest volume of biogas (4,756 ml) with a methane content of 60.37% was produced by the digester containing 75% TSW and 25% CD and the lowest biogas (2,539 ml) with quality of 68.06% was produced by digester containing 100% CD. The average methane contents of different digesters were D-1 (100% TSW) 53.23%, D-2 (75% TSW: 25% CD) 60.37%, D-3 (50% TSW: 50% CD) 58.78%, D-4 (25% TSW: 75% CD) 57.66% and D-5 (100% CD) 67.31%. Total and volatile solid removal efficiency of all digesters was in the range of 42.27-76.34% and 47.16-79.23%. The study concluded that TSW is a good feedstock for biogas production by utilizing agro-industrial based organic solid waste for bioenergy production.
