In this paper three sustainable approaches are made in waste management option. Firstly primary treated domestic sewage is treated by aquatic macrophytes using duckweed, water hyacinth and water lettuce. Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Phosphate, Nitrates are tested before and after. Result indicates in terms of water quality, almost all three plants shows same removal efficiencies. BOD and TSS removal efficiency is attained more than 95%. COD and TDS removal is reached upto 50% for almost all plants. Secondly the used aquatic macrophytes for wastewater treatment is again used for generation of biogas (water lettuce unit, duckweed unit, water lettuce unit). In addition to three aquatic macrophytes, sludge is collected from aquatic macrophyte unit for generation of biogas. Comparison is made with conventional cow dung biogas unit. Result indicates water lettuce and duckweed produce biogas at earlier stage itself and water hyacinth takes some time for starting of biogas production. This may be due to the structure and texture causes some time for decomposition. Sludge gives maximum biogas generation among all experimental setup. Also in this study cow dung did not give biogas more may be due to poor blend ratio of cow dung with water is one of the reason.

Water hyacinth (Eichhornia crassipes) causes ecological and economic problems because it grows very fast and quickly consumes nutrients and oxygen in water bodies, affecting both the flora and fauna; besides, it can form blockages in the waterways, hindering fishing and boat use. However, this plant contains bioactive compounds that can be used to produce biofuels. This study investigated the effect of various substrates as feedstock for biogas production. A 125-l plug-flow anaerobic digester was utilized and the hydraulic retention time was 14 days; cow dung was inoculated into water hyacinth at a 2:1 mass ratio over 7 days. The maximum biogas yield, achieved using a mixture of natural water hyacinth and water (NWH-W), was 0.398 l/g volatile solids (VS). The cow dung/water (CD-W), hydrothermally pretreated water hyacinth/digestate, and hydrothermally pretreated water hyacinth/water (TWH-W) mixtures reached biogas yields of 0.239, 0.2198, and 0.115 l/g VS, respectively. The NWH-W composition was 70.57% CH4, 12.26% CO2, 1.32% H2S, and 0.65% NH3. The modified Gompertz kinetic model provided data satisfactorily compatible with the experimental one to determine the biogas production from various substrates. TWH-W and NWH-W achieved, respectively, the shortest and (6.561 days) and the longest (7.281 days) lag phase, the lowest (0.133 (l/g VS)/day) and the highest (0.446 (l/g VS)/day) biogas production rate, and the maximum and (15.719 l/g VS) and minimum (4.454 l/g VS) biogas yield potential.

This study investigates the potential of biogas production from water hyacinth, water lettuce and water fern. Laboratory experiments were carried out at the Faculty of Agriculture laboratory, University of Benin, Nigeria. The aquatic weeds which are major constituents of the substrate were contained in the conical flasks used as digester. The cow dung and aquatic weeds were mixed in the ratio of 1:1; 1:2; 1:3; 1:4; and 1:5 in the different samples used for each of the three aquatic weeds and gas produced measured.The results obtained showed that no gas was produced in any of the flasks containing the aquatic weed within 21days. Gas production was however recorded in those with cow dung alone which gave 302ml of biogas within the 21 days retention period with an average of 21ml of gas produced within the active 14 days of production. The results also showed variations in gas production between daytime and night hours with minimal gas production recorded at night hours and peak production during the daytime. It was concluded that cow dung requires shorter retention time to initiate production of biogas when compared with that of the aquatic weeds and therefore can be used to sustained biogas production in aquatic weed at the early stage.

Water hyacinth is a waste that can be utilized by the community as an alternative potential for biogas energy. The formation of biogas from water hyacinth requires a residence time (LT) that is still long, which is between 30-35 days for the formation of methane. So that the process of forming methane is not too long, a stater is needed so that methanogenic bacteria can increase from cow dung so that the residence time is much shorter. The process of making biogas starts from making a digester, the process of taking water hyacinth by chopping water hyacinth, preparing cattle dung stater. The purpose of this study is to analyze technically and economically biogas from water hyacinth with cow manure stater. This research was carried out through several stages, namely: preparation of raw materials, stater and plastic biogas digester and techno-economic analysis. In this study the ratio of raw material 1: 1 (water hyacinth chopped 20 kg, water 20 kg) and the addition of stater cattle dung 6 kg. The results of this study are that the technical aspects of biogas start production after 10 days of filling the digester at pH 7.1. Biogas produced is known by direct flame test. Visible on the 10th day the resulting flame is still small, but this shows that the gas has been formed. The pH of the digester is between 4.7 and 8.5. The decrease in TS value from the inlet which is 46 kg to the outlet is 28 kg, indicating that there has been degradation in the substrate in the digester. On the economical aspect the investment cost of a biogas installation in a synthetic digester is IDR 1,500,000.00. Variable costs are the cost of water hyacinth, cow dung and water of Rp 150,000.00 per year. The Cost of Biogas Production is Rp 3,836.08 and if it is sold at a margin of 50% the selling price is Rp 5,800. The break even point in kilograms is 267.2 and in rupiahs is Rp 1.025,000.00. This payback period for investment in biogas business is 2.86 years.

The objective of this work is to determine the co-digestion ratio of water hyacinth and cow dung for the optimization of biogas production at Sô Ava, a lake city of Southern Benin. To achieve these ratios, we suppose that the water hyacinth has a high gas yield and cow dung ensures stability in the biodigester because it brings fresh bacteria and has a strong buffering capacity (maintenance of a stable pH). For 45 days, we have introduced a mixture of water hyacinth and cow dung in 5 mini-biodigesters of 10 liters each: digester no1 (100% of cow dung); digester no2 (100% of the water hyacinth); digester n° 3 (50% of the water hyacinth and 50% of the cow dung); digester no4 (75% of cow dung and 25% of water hyacinth); digester no5 (75% of the water hyacinth and 25% of the cow dung). The measurements of the pH, temperature and the proportion of gas (CH4, CO2, O2 and H2S) in the mini-biodigesters was done. The measurements show that the digester n° 5 produces the highest capacity of 15.24L of biogas with 70% of methane while the digester n °2 has the lowest capacity 5.47L of biogas with 58% methane. These results show that the yield of biogas produced is greater when using the mixture of the substrate with the ratio of 75% of water hyacinth and 25% of cow dung. This result encourages the energy recovery from water hyacinth, once considered as a seasonal plague which hinders navigation of local boat in the lake.
