“…The most important finding in this research is that the sample mixture ratio of the substrate significantly affect the biogas production. The sample mixture of C. furcata/inoculums produced up to 11.9% of CH 4 during 28 days of anaerobic digestion process compared to sample mixture of C. furcata/water ratio only produced about 1.1% of CH 4 . Besides that, activated sewage sludge can be used as inoculums for anaerobic digestion since it has important roles for start-up of the biochemical processes from anaerobic digesters.…”

“…Others gases produced during this study might consist of nitrogen, oxygen and hydrogen sulphide. Based on the results, only sample mixture of 1:3 C. furcata/water produced 1.1% CH 4 . The methane produced from the digestion process could be initiated from native microbes that naturally attached to the C. furcata.…”

“…These processes occur without the presence of oxygen [2]. A few studies have been conducted on biogas production using aquatic plants by applying anaerobic digestion process such as water hyacinth [3], Eichhornia azurea, Pistia stratiotes and Salvini [4], and water hyacinth and water chest nut [5].…”

Biogas is produced from decomposition of organic waste such as sewage sludge, animal manure, and municipality solid wastes by microorganisms in anaerobic conditions. Biogas, which consist mainly of methane is a renewable energy source. It can be used for heating, power generation or upgrading to natural gas quality. In this study, the anaerobic treatability and biogas generation potential of Cabomba furcata (C. furcata) were examined in batch digesters. C. furcata collected from Chini Lake, Pahang was utilized as a substrate in biogas production. Slurry samples of C. furcata were prepared in 2 different mixture i.e., C. furcata/water ratio (1:1, 1:2 and 1:3) and C. furcata/inoculums ratio (1:1, 1:2 and 1:3). Throughout the experiment, the pH range was 5.5 to 7.0 while temperature range was 25 to 30 °C to enable anaerobic digestion in mesophilic condition for a retention time of 28 days. The results showed that the maximum methane production achieved at ratio of 1:3 for both mixture C. furcata/water and C. furcata/inoculums with production percentages up to 1.1 and 11.9%, respectively. Moreover, the result indicated that the production of methane increased as the retention time increased. Therefore, native plant of C. furcata is a great potential as a substrate in the production of biogas for future renewable energy.Keywords: Cabomba furcata, methane production, anaerobic digestion, renewable energy Abstrak Biogas terhasil daripada penguraian sisa organik seperti kumbuhan enapcemar, baja haiwan dan sisa pepejal perbandaran oleh mikroorganisma dalam keadaan anaerobik. Biogas terdiri daripada metana sebagai sumber tenaga yang boleh diperbaharui. Ia boleh digunakan untuk pemanasan, penjanaan kuasa atau peningkatan kepada kualiti gas asli. Melalui kajian ini, kebolehrawatan anaerobik dan kebolehan penjanaan biogas oleh Cabomba furcata (C. furcata) telah diperiksa di dalam penghadam kelompok. C. furcata telah dikumpul dari Tasik Chini, Pahang dan digunakan sebagai substrat dalam penghasilan biogas. Sampel cair C. furcata disediakan dengan 2 campuran yang berlainan i.e., nisbah C. furcata/air (1:1, 1:2 dan 1:3) dan nisbah C. furcata/inokulum (1:1, 1:2 dan 1:3). Sepanjang kajian dijalankan, nilai pH adalah 5.5 hingga 7.0 manakala julat suhu ialah 25 -30 °C menjadikan keadaan operasi penghadaman anaerobik sebagai mesofilik dan masa tahanan selama 28 hari. Keputusan kajian menunjukkan penghasilan biogas yang maksimum berlaku pada nisbah 1:3 untuk kedua-dua campuran C. furcata/air dan C. furcata/inokulum dengan peratusan penghasilan masing -masing meningkat kepada 1.1 dan 11.9%. Selain itu, keputusan juga menunjukkan penghasilan semakin meningkat apabila masa tahanan meningkat. Oleh itu, C. furcata mempunyai potensi yang bagus sebagai substrat dalam penghasilan biogas untuk tenaga yang boleh diperbaharui pada masa depan.

“…After the 1 L BMP, the batch study was scaled up to 20 L and it was conducted for 80 days.Anaerobic co-digestion of water hyacinth (WH) with sheep waste (SW) are placed in 6 digesters [ WHB (8g WH & 92g water), SW1(2g WH,18.01 g SW &79.99g water), SW2(3g WH, 15.01g SW &81.90g water), SW3(4g of WH, 12.01g SW &83.90 g water), SW4(5g WH, 9.01g SW & 86g water), SWB with 24g of SW & 75.97 g water.] in 30-37℃ with 8% TS for 60 days retention period.12 sets of anaerobic digestion were performed in 1lit of glass reactor with pre-treated water hyacinth (fresh and dry water hyacinth with 2%(w/v) of NaOH and 10% (w/v) of Lime solution at 140℃ for 4 hours treatment and total sugar content was determined).3 types of dung (pig dung, elephant dung and bat dung) were used as co-substrate.Biogas production was done by 400g of each pre-treated water hyacinth, 400ml of each dung and 200ml of waste water at 37 ± 2℃ for 45 days.1.5kg water hyacinth,500ml of distilled water is used to prepare the slurry and 3.5kg of fresh cow rumen is used to perform the anaerobic digestion process at pH 6.8, 30-40 ℃ temperature Two set (Set-I & Set-II) of BMP test was conducted in 1L batch digester and macro and micro nutrients are also supplied with the addition of Substrate, co-substrate and inoculum with the mixing ratio 1.0, 1.5, 2.0, 2.5 in both set up.Set-I contains untreated water hyacinth while set-II contains pretreated (hot air oven, 90℃ for 1hr) and cooked food waste was common in both set up.Different studies byPantawong et al (2015),Pereira et al (2011), Nipaney and Panholzer (1987) have observed maximum methane content of 66.35%, 50%, and 68%, respectively, from water lettuce, using different inoculum. Pistia produced a high volume of CO2 and signi cant amounts of propionic, butyric, isobutyric, valeric and isovaleric acids(Abbasi et al 1991).…”

Aquatic weeds have exceptionally high reproduction rates, are rich in cellulose and hemicellulose, and contain a negligible amount of lignin, making them an ideal crop for the next generation of biofuels. Previously reported studies proposed that water hyacinth, water lettuce, common duckweeds, and water spinach can be managed or utilized using different advanced techniques, while anaerobic digestion is one of the feasible and cost-effective techniques to manage these biowastes. The present study was carried out to investigate the potential of utilizing four common aquatic weed species (water hyacinth, water lettuce, common duckweeds, and water spinach) as substrates for anaerobic digestion in order to produce biogas. The high reproduction rates, high cellulose and hemicellulose content, coupled with low lignin content, of these aquatic weeds make them ideal candidates for this purpose. The study evaluated the feasibility of anaerobic digestion as a management method for these aquatic weeds, which are often considered invasive and difficult to control. The study provides an overview of the characteristics and management strategies of these aquatic weeds in relation to biogas production, with possible future developments in the field.

El objetivo de este trabajo fue la preparación y caracterización física de biocombustible sólido usando la biomasa del lirio acuático para su valorización. Este trabajo incluye la caracterización de las propiedades del lirio acuático deshidratado, el desarrollo de un proceso de fabricación en briquetas y la caracterización de las briquetas propiedades a temperatura ambiente. Las propiedades analizadas varían dependiendo de la fuerza ejercida sobre la briqueta ya que la presión de la densificación afecta fuertemente sus propiedades físicas. Basado en los resultados del estudio, se concluye que estos biocombustibles pueden ser producidos a nivel industrial, constituyendo una buena fuente alternativa de energía. Palabras clave: biocombustible sólido, biomasa, briqueta, lirio acuático AbstractThe aim of this work was the preparation and the physical characterization of solid biofuel made from biomass of water hyacinth for its valorization. This work included the characteriziation of the properties of dehydrated water hyacinth, the finding of a process to transform them into briquettes and the characterization of the briquettes at room temperature. The analyzed properties depend on the charge exerted over the briquette since densification pressure strongly affects the physical properties of the briquette. Based on the results of study it is concluded that the biomass fuel could be produced at industrial level, being a good source of non convenctional energy.
