“…They combined crab waste with 0, 5, 10, and 15% liquid molasses and stored it in mini-silos for 14 days. Fresh SW was combined with 0, 10, 15, 20, and 25% dry molasses and colony-forming bacteria for 6 days (Zakaria et al 2022 ). They reported increased lactic acid fermentation with a significant decrease in ammonia, butyric, and propionic acid.…”

The seafood industry generates waste, including shells, bones, intestines, and wastewater. The discards are nutrient-rich, containing varying concentrations of carotenoids, proteins, chitin, and other minerals. Thus, it is imperative to subject seafood waste, including shrimp waste (SW), to secondary processing and valorization for demineralization and deproteination to retrieve industrially essential compounds. Although several chemical processes are available for SW processing, most of them are inherently ecotoxic. Bioconversion of SW is cost-effective, ecofriendly, and safe. Microbial fermentation and the action of exogenous enzymes are among the significant SW bioconversion processes that transform seafood waste into valuable products. SW is a potential raw material for agrochemicals, microbial culture media, adsorbents, therapeutics, nutraceuticals, and bio-nanomaterials. This review comprehensively elucidates the valorization approaches of SW, addressing the drawbacks of chemically mediated methods for SW treatments. It is a broad overview of the applications associated with nutrient-rich SW, besides highlighting the role of major shrimp-producing countries in exploring SW to achieve safe, ecofriendly, and efficient bio-products.

“…This excess phosphorus can contribute to eutrophication, disrupting aquatic ecosystems. Additionally, phosphorus applied to soils can become immobilized or fixed by soil minerals, making it less available for plant uptake (Bowler et al 2010, Zakaria et al 2022. Furthermore, phosphorus can form insoluble compounds with other elements in the soil, reducing its effectiveness as a nutrient for plants.…”

“…This linear movement of P from mines to oceans is much larger than the closed P cycles in natural ecosystems. Less than 20% of P is typically reclaim, resulting in significant wastage and leakage into water bodies throughout the food production and consumption chain (Slocombe et al 2020, Zakaria et al 2022. According to Schaum (2018) this trend is expected to worsen due to climate change and the increasing global demand for food.…”

“…Phosphorus is currently present in excessive quantities in many freshwater ecosystems worldwide, whether in developed or developing regions. This surplus is primarily the result of widespread use of P-rich fertilizers and the direct discharge of untreated or partially treated human waste into water bodies through sewerage systems (Bennett et al 2001, Zakaria et al 2022. In undisturbed natural environments, P is introduced into freshwater systems through inherent natural mechanisms, including the weathering and erosion of bedrock and catchment soil, as well as the input of organic materials like leaf litter and animal excrement from terrestrial surroundings.…”

Indonesia is renowned as an agricultural powerhouse, ranking first globally in oil palm production. This prominence in agriculture leads to the consistent generation of agro-industrial waste, notably Palm Oil Mill Effluent (POME). Effectively addressing these waste concerns is important due to their adverse impacts on aquatic ecosystems and the nation's health and economy. Anthropogenic wastewater with excessive phosphorus content can trigger eutrophication and toxic algal blooms, posing environmental risks and potentially precipitating a future clean water crisis. Thus, a comprehensive approach is necessary to restore the environment and biogeochemical cycles. Treatment efforts involving bioremediation agents aim to recycle organic and inorganic pollutants in the environment. Photosynthetic organisms like plants and microalgae serve as effective bioremediation agents, capable of absorbing excess phosphorus. They can utilize phosphate as an energy source to boost biomass. Integrating these bioremediation agents with bioengineering technology optimizes the treatment efficacy while simultaneously producing valuable biomass for products and bioenergy. This review article explores photosynthetic organisms' multifunctional role as phosphorus bioremediation agents for wastewater treatment, minimizing environmental pollutant impacts, and providing biomass for fertilizers, polymers, bioplastics, and renewable energy. Furthermore, this study unveils opportunities for future technological advancements in this field.

BackgroundMicrobial fuel cell, a potential cost‐effective technology for the energy neutral treatment of wastewater. However, the successful implementation of this technology in resource recovery is still limited. In this study, a microbial electrochemical cell was designed and operated for 30 days. The critical factors assessed for removal and recovery of N and P as struvite from wastewater.ResultsThe optimization studies on critical factors like the chemical oxygen demand of wastewater (500–2000 mg/L) and cathode aeration rate (45–135 mL/min) were conducted using the pure culture of Escherichia coli. The system yielded an average power densityof 465 mW/m2, average current density of 915 mA/m2 and P recovery at an extent of 40% as struvite. Additionally the maximum reduction in the COD of 90% with an average coulombic efficiency of about 82% was obtained at a short interval of 30 days. The solubility studies of the recovered struvite for 12 h. at different pH from 4.5 to 9 showed maximum solubility of 80% at 4.5 and minimum of 3.5% at 9.ConclusionThis study moves one step closer to applying MFC technology for N and P‐rich wastewater treatment with concurrent struvite precipitation and electricity production. In this way, Sustainable Development Goals 2, 6, and 7 can be achieved through resource recovery, clean water, and bioenergy.This article is protected by copyright. All rights reserved.
