“…It is also important to note that several authors referred to the anaerobic digestates as “biofertilizers”, though the standard definition of the term “biofertilizers’’ often denotes the use of biologically active preparations that contain beneficial microorganisms that enhance plant growth and yield. Similar nomenclature can be seen in [ 170 , 171 , 172 , 173 ] and many more. Similarly, the term “organic fertilizer” is often used to indicate the production of a sustainable fertilizer from by-products of agriculture, and pastoral farming, such as manure, litter, and poultry droppings by means of composting or anaerobic digestion [ 174 ].…”

The plant-microbe holobiont has garnered considerable attention in recent years, highlighting its importance as an ecological unit. Similarly, manipulation of the microbial entities involved in the rhizospheric microbiome for sustainable agriculture has also been in the limelight, generating several commercial bioformulations to enhance crop yield and pest resistance. These bioformulations were termed biofertilizers, with the consistent existence and evolution of different types. However, an emerging area of interest has recently focused on the application of these microorganisms for waste valorization and the production of “bio-organic” fertilizers as a result. In this study, we performed a bibliometric analysis and systematic review of the literature retrieved from Scopus and Web of Science to determine the type of microbial inoculants used for the bioconversion of waste into “bio-organic” fertilizers. The Bacillus, Acidothiobacillus species, cyanobacterial biomass species, Aspergillus sp. and Trichoderma sp. were identified to be consistently used for the recovery of nutrients and bioconversion of wastes used for the promotion of plant growth. Cyanobacterial strains were used predominantly for wastewater treatment, while Bacillus, Acidothiobacillus, and Aspergillus were used on a wide variety of wastes such as sawdust, agricultural waste, poultry bone meal, crustacean shell waste, food waste, and wastewater treatment plant (WWTP) sewage sludge ash. Several bioconversion strategies were observed such as submerged fermentation, solid-state fermentation, aerobic composting, granulation with microbiological activation, and biodegradation. Diverse groups of microorganisms (bacteria and fungi) with different enzymatic functionalities such as chitinolysis, lignocellulolytic, and proteolysis, in addition to their plant growth promoting properties being explored as a consortium for application as an inoculum waste bioconversion to fertilizers. Combining the efficiency of such functional and compatible microbial species for efficient bioconversion as well as higher plant growth and crop yield is an enticing opportunity for “bio-organic” fertilizer research.

“…The functional unit in a LCA study represents the reference for all calculations and how to assess environmental impacts. 20 Choosing this reference is an essential step for any AVC study due to the possibility of producing several products from a single one initially, which can make it difficult to identify the main function of the system requiring additional when analyzing the results. According to the work carried out by Ahlgren et al in 2013, 21 there are three different ways to choose the functional unit, either by the quantity of input and by the output of a single product or the combination of several outputs.…”

“…When PABs are grown and harvested, a large amount of waste (including leaves, pseudo-stems, rhizomes, and peel, among other things) is collected along with the entire fruit at the storage stage to generate PBB, which does not meet the requirements for sale [31], though the PBB can reflect massive bioenergy potential for the future. Furthermore, PBB can be transformed and used in a variety of activities, including biofertilizers, textiles, polymer synthesis, waste water treatment, and others [32].…”

“…Numerous studies have reported advanced fruit peel and plant applications for livestock feed optimization [51]. Because PBB contains a significant amount of organic material and water, it cannot be disposed of in a landfill under existing law [31]. PBB's high moisture content makes it challenging to valorize using pyrolysis and incineration techniques.…”

“…In an environmental comparison of banana waste valorization strategies under a biorefinery approach. Santiago et al [31] reported that bioethanol production from banana peels generates a solid waste flow that is managed in an AD plant, obtaining biogas to be converted into energy and digestate, which is considered as a potential biofertilizer. The drying of banana peels to lower their moisture content, heating the inflow stream prior to fermentation, and subsequent distillation in the appropriate columns are the operations that have the largest energy demands.…”

Globally, fossil fuel dependence has created several environmental challenges and climate change. Hence, creating other alternative renewable and ecologically friendly bio-energy sources is necessary. Lignocellulosic biomass has gained significant attention recently as a renewable material for biofuel production. The large amounts of plantain and banana plant parts wasted after harvesting, as well as the peels generated daily by the fruit market and industries, demonstrate the potential of bioenergy resources. This review briefly assesses plantain and banana plant biomass (PBB) generated in the developing, developed, and underdeveloped countries, the consumable parts, and feasible products yield. It emphasized the advantages and disadvantages of the commonly adopted treatment technologies of composting, incineration, and landfilling. Further, the utilization of PBB as catalysts in biodiesel synthesis was briefly highlighted. To optimize recovery of biofuel, different integration routes of pyrolysis, anaerobic digestion, fermentation, hydrothermal carbonization, hydrothermal liquefaction, and hydrothermal gasification for the valorization of the PBB were proposed. The complex compounds present in the PBB (hemicellulose, cellulose, and lignin) can be converted into valuable bio-products such as methane gas and bio-ethanol for bioenergy, and nutrients to promote bioactive ingredients. The investigation of the viability and innovation potential of the integrated routes' technology is necessary to improve the circular bio-economy and the recovery of biofuels from biomass waste, particularly PBB.
