“…All mixture ratios showed high moisture contents at the end of composting (around 40%), higher than the recommendation of Shammas and Wang [7], and Füleky and Benedek [12], who advocated a lower moisture content at the end of composting. Furthermore, it was also higher than the maximum allowable limit of 35% by Vietnamese standards (10TCN 526:2002).…”

Seafood sludge (SS) was one of the solid wastes generated during the wastewater treatment processes of seafood processing factories, and it increasingly discharged to the environment. This study aimed to reuse sludge from seafood wastewater treatment plants for producing microbial-organic fertilizer to handle environmental pollution. SS samples were collected at seafood factories in Dong Thap province. Other materials, including sugarcane filter cake (SC) and bagasse (B) were collected in Hau Giang province. Five treatments with three replications for each consisted of a mixture ratio of SS, SC and B at (1) 10-60-30, respectively; (2) 10 + 70 + 20; (3) 20 + 60 + 20; (4) 10 + 70 + 20 and (5) 20 + 80 + 0. All composting mixtures were analyzed for temperature, moisture content, pH, electrical conductivity, volume reduction, organic carbon (OC), total nitrogen (TN), total phosphorus (TP) and total potassium (TK) at stages of 0 and 49 days after incubation. Results after 49 incubation days showed that the pH value of both kinds of sludge was slightly acid to neutral (6-7). Electrical conductivity values were suitable from 0.74 to 1.57 mS/cm. The weight loss of incubated samples was 35.87-77.56% after a 49-day incubation. Organic carbon contents were at a high level (over 30% C). After 49 incubation days, the TN, TP, and TK content were high at 2.01-3.03%N; 6.71-9.95%P2O5; and 2.62-3.15%K2O, respectively. The C/N ratio ranged from 12.15 to 19.1. The optimal ratio was mixed with 20% seafood sludge and 80% sugarcane filter cake. The period of 49 days was seen as the suitable incubation time for composting maturity and stability.

“…Compost and vermicompost are waste-derived products found in the set of patents associated with sustainable fertilizer productions (Figure ). Composting is the aerobic, thermophilic, microorganism-mediated bioconversion of organic matter into humic substances called compost . The process of composting is as follows: Organic waste (Protein + Cellulose + Lignin) + O 2 → Compost + CO 2 + H 2 O + Heat .…”

The ability of modern agriculture to meet future food demand imposed by accelerating growth of the world’s population is a major challenge, and fertilizers play a key role by replacing nutrients in agricultural soil. Given the need for fertilizers, their cost in nonrenewable resources and energy, and the consequences of the greenhouse gas emissions required to make them, people have begun to explore ways to make fertilizer manufacturing and use more sustainable. Using data from the CAS Content Collection, this review examines and analyzes the academic and patent literature on sustainable fertilizers from 2001 to 2021. The breakdown of journal and patent literature publication over time on this topic, country or region of publications, the substances included in published research, among other things allow us to understand the general progress in the field as well as the classes of materials and concepts driving innovation. We hope that this bibliometric analysis and literary review will assist researchers in relevant industries to discover and implement ways to supplement conventional fertilizers and nutrient sources while improving the efficiency and sustainability of waste management and ammonia production.

“…On the other hand, sustainable alternatives exist, such as composting, defined according to the FAO as “ the mixing of decomposing organic matter under aerobic conditions used to improve soil structure and provide nutrients ” [ 15 ]. It is an aerobic process in which microorganisms transform organic material into more stable and useable compounds for soil and crops [ 16 ]. Composting brings several physical, chemical and microbiological soil benefits, such as improving soil structure for planting purposes, contributing to the distribution of nutrients [ 17 ], stabilisation and mineralisation of organic residues [ 16 ], production of humic substances [ 18 ], reduction of xenobiotic compounds such as pesticides [ 19 ], eradication of pathogens due to the high temperatures that the process undergoes (ensuring human health through stabilisation and treatment of zoonotic pathogens), odour control, recovery and prevention of soil desertification, the contribution of compounds such as nitrogen, potassium and phosphorus, and reduction of greenhouse gas emissions [ 17 ].…”
