Increasing wastewater treatment efficiency is a primary aim in the circular economy. Wastewater physicochemical and biochemical processes are quite complex, often requiring combination of statistical machine learning tools to empirically model them. Since plants large-scale operations, limited opportunities for extensive experimentation may be offset by miniaturizing experimental schemes through use fractional factorial designs (FFDs). A recycling quality improvement study that relies on non-linear multi-objective multi-parameter FFD (NMMFFD) datasets was reanalyzed. published NMMFFD ultrafiltration screening/optimization case re-examined regarding how four controlling factors affected three paper mill characteristic responses using methods. Comparative screening predictions were provided (1) quadratic support vector regression (2) optimizable regression, contrast linear regression. optimization performed employing Pareto fronts. Pseudo-screening applied decomposing replicated dataset single replicates then testing their replicate repeatability introducing belief functions sought maximize credibility plausibility estimates. Various versions considered, since novel role process characteristics, as independent sources, created high level conflict during information fusion phase, due inherent divergent structures. Correlations between two but with opposite goals, also have contributed source conflict. The active effects found transmembrane pressure molecular weight cut-off. modified adjustment pinpointed cut-off at 50 kDa, while optimal setting persisted 2.0 bar. This mixed-methods approach provide additional confidence determining improved adjustments. It would interesting implement this polyfactorial screenings greater number characteristics.

Phosphorus (P) is a vital element for optimal crop growth and agricultural productivity. Struvite, P precipitate obtained from wastewater, recognized as slow-release, low-solubility fertilizer. The objective of this study was to evaluate the impact inoculation with yeast Naganishia albida on bioavailability using struvite triple superphosphate (TSP) in lettuce (Lactuca sativa L.) plants. Struvite fertilization improved N assimilation by 14–28% 12–27%, respectively, compared TSP increased soil soluble 50% more than 186% control. Inoculation reduced oxidative stress 40–44%, plant 28% 7% TSP, acid phosphatase activity 52.7% 78.1%, improving nutrient bioavailability. showed high solubility soil, only 3% difference between inoculated non-inoculated treatments. In addition, combination fertilizer had synergistic effect, increasing enzyme up 1.8 times 2.3 TSP. results highlight potential recycled effectiveness integrating microorganisms improve efficiency, reduce environmental promote sustainable management framework circular economy.

The current use of fertilizers is inefficient and not sustainable. majority the fertilizer applied does reach targeted crop but lost in water bodies into atmosphere, with harmful impact on environment. To enhance efficiency sustainability agricultural practices, it essential to address two complementary challenges. First, nutrient delivery methods must be refined maximize plant uptake. Second, recovery nutrients from wastewater other waste streams should improved recycling nitrogen phosphorous reduce environmental pollution. Biodegradable polymers hold great promise for development technological solutions toward more sustainable practices. This review covers application biodegradable both aspects cycle: plants through slow- controlled-release fertilizers, using membrane separation, adsorbent composites, coagulants/flocculants. most promising materials are highlighted approaches, identifying research gaps discussing potential future directions this highly significant field.

Abstract: The escalating global demand for water, alongside diminishing freshwater resources, has heightened the urgency sustainable wastewater management solutions. Circular Economy seeks to transform from an environmental burden into a valuable resource by minimizing waste and maximizing recovery. This study investigates essential strategies implementing circular economy practices, focusing on water reuse, nutrient recovery, energy generation foster both sustainability economic viability. It also examines recovery of resources like biogas, phosphorus, nitrogen, which contribute agricultural productivity. research further delves policy frameworks, factors, societal influences that affect adoption practices. Emphasis is placed collaborative roles governments, industries, communities in advancing solutions addressing implementation challenges. integration smart technologies, including IoT data analytics, highlighted as means optimize improve system efficiency. Findings suggest adopting can significantly reduce impacts, lower operational costs, create new opportunities within sector. Nonetheless, challenges such technological limitations, regulatory barriers, financial constraints, public acceptance must be addressed fully realize these benefits. contributes expanding body knowledge management, offering roadmap policymakers, engineers, stakeholders develop resilient systems support objectives security, climate resilience, Future should focus scaling solutions, conducting life cycle assessments, evaluating long-term socio-economic impacts strategies.
