“…The statistical analysis showed that the biogas production of P2 and F2 were significantly higher (p < 0.05) than the P1 and F1 ( Figure S2). This finding may confirm the beneficial effect of the co-digestion process on biogas production [55][56][57]. High increase of biogas production was also demonstrated via the co-digestion approach utilizing different substrates (municipal sludge, grease trap waste, and meat processing waste) [58].…”

Methane Production from Alginate-Extracted and Non-Extracted Waste of Laminaria japonica: Anaerobic Mono- and Synergetic Co-Digestion Effects on Yield

This study investigated the potentiality of methane production from alginate-extracted (AEWLJ) and non-extracted (NAEWLJ) waste of Laminaria japonica through batch anaerobic fermentation in mono- and co-digestion with rice straw (RS) at different mixing ratios. Optimal C/N ratio was demonstrated, and system stability was monitored in terms of the total ammonia nitrogen, total volatile fatty acids, and pH throughout the digestion period. The results show that the combination of AEWLJ/RS at 67% mixing ratio generated the highest biogas yield of 247 NmL/gVS, which was 36% higher than the AEWLJ alone. The synergetic effect was clearly observed leading to an increase in the total methane yield up to 78% and 88%, respectively, for arrays of AEWLJ/RS and NAEWLJ/RS. The kinetic model showed a high coefficient of determination (R2 ≥ 0.9803) when the modified Gompertz model was applied to predict methane production. These outcomes support the possibility of an integrated biorefinery approach to attain value-added products in order to achieve circular economies.

“…To reduce pollution from livestock farms and agro-process industries and provide better solid and liquid waste management, new and stricter regulations must be established in African countries. Anaerobic digestion, producing biogas, is one of only a few biotechnological processes, which utilise such wastes effectively while generating energy [1,114]. It has been used widely in the waste stabilisation process because of the need to treat waste before disposal, and the need to reduce methane emission into the environment [115,116].…”

A Review of Commercial Biogas Systems and Lessons for Africa

2018

Many African countries have vast biomass resources that could serve as feedstock for methane production through the adoption of commercial biogas plants. However, due to many inhibiting factors, these resources are under-utilised. This article reviews commercial biogas systems that treat organic waste from municipalities, large livestock farms, large plantations/crop farms, food/beverage production facilities, and other industries, to identify essential lessons which African countries could use to develop/disseminate such biogas systems. The review identified the critical barriers to commercial biogas development to be high initial capital costs, weak environmental policies, poor institutional framework, poor infrastructure and a general lack of willpower to implement renewable energy policies and set challenging targets. In African countries where feed-in-tariffs, quota obligations and competitive bidding programmes have been instituted, implementation has been poor, and most state-owned utilities have been unsupportive. Using knowledge from more experienced countries such as Germany and China, some key lessons have were identified. Among the key lessons is the need to institute and enforce environmental management policies to ensure that waste from medium and large livestock farms and industries are not disposed of indiscriminately, a tool China has recently used to promote commercial biogas plants to a high degree of success.

“…There are a variety of treatment methods which are available to treat the poultry excreta by composting [29], anaerobic digestion [30], anaerobic co-digestion [31], thermophilic anaerobic digestion [32], Biogas production [33], fluidized bed combustion [34], Vermicomposting [35], etc., but every method has its own limitations. Hence innovative and easy technologies are required to treat the poultry excreta in a sustainable manner for every kind of poultry farm.…”
