“…A 19‐L plastic water container was chosen as the main digester tank and was painted black to prevent light penetration and inhibit algae growth as well as to facilitate heat absorption and maintain mesophilic conditions for biogas production. [ 24,25 ] The digester tank was equipped with one inlet and two outlets. The mouth of the 19‐L bottle acted as the main inlet for inserting the feedstock and was subsequently sealed before the digestion.…”

Leftover harvested water hyacinth biomass and duck manure can create waste management issues. As they are readily abundant and available, potential co-digestion of both waste sources for biogas production is explored as a waste-to-energy approach for a rural fishermen community. Seven 19-L do-it-yourself bioreactors are constructed with four different feedstock mixing ratios. The mixing ratios of water hyacinth to duck manure are varied at 70:30, 50:50, and 30:70, and are conducted in duplicate. One reactor utilizing 100% water hyacinth as feedstock acts as the control. Biogas production is measured daily for 50 days through the water displacement method. Variations in pH and chemical oxygen demand levels are monitored weekly. The results show that the highest biogas production is from the mixture of water hyacinth to duck manure at a 70:30 ratio (p < 0.05), with a volume of cumulative gas produced at 4.27 L that can be well simulated through the logistic function kinetic model (R 2 = 0.965). The biogas produced consists of methane, carbon monoxide, and hydrogen sulfide. The findings prove the potential of water hyacinth and duck manure as feedstocks for biogas production as one of the waste management solutions that can be practiced by the community.

“…The fabrication of biogas digesters using plastics is said to be because of high labor cost as well as leakages associated with the use of bricks, cement and concrete in convectional biogas digesters 37 . According to Kumar and Bai, 38 biogas digesters fabricated using plastics are characterized to be a non‐corrosive, good insulator, cheaper and easy to fabricate and maintain. Different types of plastics have been used for fabricating biogas digesters.…”

Summary This article reviews the various materials used for the construction and fabrication of biogas digesters. The reviewed materials include bricks, cement, plastics, reinforced fiber, and metals, which find its application in household biogas digester design. The review aims to provide and help energy engineers and researchers as well as stakeholders in the selection of an appropriate material for the construction and fabrication of biogas digesters. More also, the present study will present information on the challenges associated with each material and how to minimize it to enhance the development of biogas digesters technology. Detailed information on the gas yields resulting from the biogas digesters constructed and fabricated using bricks, cement, plastics, and metals as well as material used for biogas storage are reviewed. Though, findings show that most local and household biogas digesters were constructed with bricks and cement due to their rigidity, robustness, and lifespan. However, in areas where logistics and transportation may prove challenging, the likely substitute is soft bag digester owing to the light weight.

Biogas technology and anaerobic digestion is a well-established process for energy generation but there are still technical and economicbarriers to advancement of this technology especially in developing countries. Considering the relatively long retention time of the materials inside the bioreactors, the material of construction of the bioreactor is important for commercial applications and should be selected considering cost, lifespan, effectiveness, design and operation of the bioreactor. The design and operation of particularly householdand smaller bioreactors with their challenges are reviewed in this study. A particular attention is made to the new textile bioreactors that are relatively new in the market. The laboratory and pilot scale results shows that the innovative textile bioreactor is a promising technology for global energy generation advancement
