Graphical abstract The residual slurry obtained from the anaerobic digestion (AD) of biogas feed substrates such as livestock dung is known as BGS. BGS is a rich source of nutrients and bioactive compounds having an important role in establishing diverse microbial communities, accelerating nutrient use efficiency, and promoting overall soil and plant health management. However, challenges such as lower C/N transformation rates, ammonia volatilization, high pH, and bulkiness limit their extensive applications. Here we review the strategies of BGS valorization through microbial and organomineral amendments. Such cohesive approaches can serve dual purposes viz. green organic inputs for sustainable agriculture practices and value addition of biomass waste. The literature survey has been conducted to identify the knowledge gaps and critically analyze the latest technological interventions to upgrade the BGS for potential applications in agriculture fields. The major points are as follows: (1) Bio/nanotechnology-inspired approaches could serve as a constructive platform for integrating BGS with other organic materials to exploit microbial diversity dynamics through multi-substrate interactions. (2) Advancements in next-generation sequencing (NGS) pave an ideal pathway to study the complex microflora and translate the potential information into bioprospecting of BGS to ameliorate existing bio-fertilizer formulations. (3) Nanoparticles (NPs) have the potential to establish a link between syntrophic bacteria and methanogens through direct interspecies electron transfer and thereby contribute towards improved efficiency of AD. (4) Developments in techniques of nutrient recovery from the BGS facilities’ negative GHGs emissions and energy-efficient models for nitrogen removal. (5) Possibilities of formulating low-cost substrates for mass-multiplication of beneficial microbes, bioprospecting of such microbes to produce bioactive compounds of anti-phytopathogenic activities, and developing BGS-inspired biofertilizer formulations integrating NPs, microbial inoculants, and deoiled seed cakes have been examined.

“…Trace element additives such as nickel, iron, zinc, and cobalt are used in magnetic combinations such as nickel ferrite, nickel zinc ferrite (Fe 4 NiO 4 Zn), and nickel cobalt ferrite NPs for the efficient anaerobic breakdown of biomass 165 . It was observed that the addition of nickel ferrite nanoparticles induced the biogas and methane production process by increasing the bioavailability of Ni 2+ and Fe 3+ cations.…”

In a world where fossil fuels are running out, biofuels are one of the best green energy alternatives to fuels made from petroleum due to their environmentally beneficial qualities and low cost in comparison with non-renewable fossil fuels. Biofuels are produced from cheap and renewable sources and the energy stored in these biomasses can be assimilated to create sustainable electricity or heat, which can then be exploited to meet current and future societal needs in numerous situations. However, the production of biofuels on an industrial scale takes a lot of time because of the numerous constraints placed on currently available technology and the increased costs that go along with them. Moreover, the processes utilized to transform various feedstocks into the desired output also vary based on the materials and techniques employed. The supply of biofuel feedstocks is large, and with improved processing, we could significantly lower our reliance on fossil fuels. In this context, the use of nanoparticles (NPs) is a commendable solution to the present problems with biomass use, especially given their low cost. The unique qualities of nanomaterials, such as excellent catalytic properties, high surface area-to-volume ratio, remarkable selectivity, and reusability make them admirable tools for boosting biofuel generation. This review predominantly focuses on the contributions of nanotechnology and various immobilization methodologies in accelerating biofuel production from biomasses that might fill in the research gap, which was previously limited by the relatively lower efficiency of traditional techniques of biofuel generation.

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.
