Marine biomass (such as wild seaweed Gracilaria verrucosa) is highly abundant in Indonesia and has been highlighted as a potential biomass resource for bioenergy production. Furthermore, agro-industrial waste (such as tofu dregs/TD which arises from large scale production in the country) is rich in carbohydrates and proteins, and is therefore considered a viable feedstock for production of high-value added products. This study aimed to investigate the co-digestion of wild seaweed G. verrucosa (WGv) with TD and its impacts on biogas and methane production. The biochemical methane potential (BMP) test was operated for 28 days at temperature of 37 o C. The co-digestion of WGv with TD at 90:10 and 80:20 ratios significantly increased the specific methane potential (SMP), giving an average of 98 LCH4/kgVS and 120 L CH4/kgVS, respectively. Addition of co-digestion substrates promoted co-metabolism in the digesters, increasing the ability of the microorganism to effectively digest the organic matter present in the feedstock's mixture. The washing pre-treatment reduced the concentration of inorganic compounds and salts within the wild seaweed G. verucosa, leading to an improvement in biogas and methane yield. The mass balance illustrated that this process configuration led to a reduction in the quantity of digestate to be managed (i.e. dewatering, transport, and land/soil application). This will subsequently reduce the cost and energy requirements for sludge management, estimated at 37%. Therefore, the co-digestion of WGv with TD and the application of a washing pre-treatment stage prior to AD can positively enhance biogas and methane production. Indepth investigation for optimal valorisation using AD technology is highly essential.

“…Many studies have reported making briquettes using biomass other than rice husks [8], such as using cocoa pods [9][10], peanut shells [11], cotton stalks [12], corn cobs [13][14][15][16], and coconut shells [11; 17]. However, rice husk utilization as briquetting material is always attracting due to its huge generation following food production, mainly in Asia and Africa [18].…”

As the huge consumption of rice worldwide, the amount of production waste also increases. The purpose of this study was to investigate rice husk utilization for briquettes solid fuel which has aroused a great concern in the last few decades and growing number of related publications. Therefore, a bibliometric analysis of these publications may provide a direction of novel topics and prospective research trends. The related global literatures published between 2012 and 2021 have been scanned from ScienceDirect collection database. “Biochar briquettes” and “rice husk briquettes” are used as the keywords. VOSviewer is applied to perform the bibliometric analysis of these articles. In the same time, literature review has been done to analyze the research trends on rice husk-based briquetting. Totally 400 publications on the topic of biochar briquettes were identified and “biomass” with a total link strength of 90 appeared as the most frequent keywords.
