Constructed wetlands (CWs) are engineered water treatment systems that mimic the features and functions of natural wetlands. As a nature-based solution (NBS) for wastewater treatment, CWs sustainable cost-effective while providing various ecosystem services. However, their widespread application faces several uncertainties, particularly in developing countries. This study aims to analyze success factors challenges implementing CW projects. Using case successful Bayawan City Philippines, this surveyed 270 household heads from community benefiting interviewed stakeholders, including project planner, management, leader, social workers, workers. The results showed 89% respondents were aware existence 73% believed long-term sustainability. Among identified implementation government support (43%), good governance (32%), public (14%). On other hand, was challenged by improper maintenance (63%), overcrowding (11%), foul smells (4%), funding climate-related calamities flooding (7%), earthquakes sea level rise (11%). implications these discussed real options valuation projects incorporating uncertainties into flexible decision making scaling up more NBS resources management.

Abstract Microalgae’s adaptability and resilience to Earth’s diverse environments have evolved these photosynthetic microorganisms into a biotechnological source of industrially relevant physiological functions biometabolites. Despite this, microalgae-based industries only exploit handful species. This lack biodiversity hinders the expansion microalgal industry. Microalgal bioprospecting, searching for novel biological algal resources with new properties, remains low throughput time-consuming endeavour due inefficient workflows that rely on non-selective sampling, monoalgal culture status outdated, non-standardized characterization techniques. review will highlight importance bioprospecting critically explore commonly employed methodologies.

Wastewater represents an alternative source of nutrients in which to grow microalgae, whilst improving the quality wastewater, and reducing downstream treatment required. However, commercialisation microalgal cultures for such duties faces a number challenges, predominantly high cost low productivity. Suspended-solid reactors (ssPBR) can reduce operational costs, while promoting attached suspended microalgae growth. In present study, novel approach was developed by integrating wastewater with carrier systems favour growth both cells T. obliquus.

Aquaculture systems globally face significant environmental challenges, particularly concerning wastewater management. This review explores the innovative application of oxygenic photosynthetic microorganisms (OPhMs), specifically microalgae and cyanobacteria, as a sustainable solution for treatment within these systems. OPhMs offer dual role in by removing harmful pollutants such nitrogen, phosphorus, heavy metals, while simultaneously improving water quality through oxygenation. We evaluate integration into existing aquaculture operations, considering key factors system design, operational conditions, economic viability. Additionally, we discuss potential algal biomass secondary resource producing biofuels, animal feed, other bio-products, contributing to circular economy model. Our findings highlight ability OPhM significantly reduce ecological footprint recovering valuable resources. However, challenges process stability, especially under low-temperature efficiency harvesting, require further research. study provides comprehensive framework future development optimization OPhM-based improve sustainability operations.
