Life Cycle Assessment and Techno-Economic Analysis of Utilizing Waste Nitrogen to Develop Microbial Protein from Cyanophycin Accumulating Organisms.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
To advance a nitrogen circular economy, wastewater treatment plants (WWTPs) must use technologies that recover waste nitrogen and transform it into valuable products. One emerging option is partition-release-recover (PRR) technology. It transforms waste nitrogen into cyanophycin-accumulating organism microbial protein (CAO MP), which can be used as a protein source in animal feed. In this study, we perform a life cycle assessment and techno-economic analysis of a prospective WWTP configuration that incorporates this technology and assess whether it merits further development. Conventional activated sludge and anaerobic/anoxic/oxic WWTP systems are comparator baseline systems. We compare CAO MP to five different protein sources (soybean meal, alfalfa feed, fishmeal, cottonseed feed, and dried distiller grain solubles). The PRR approach has a median GWP that is 1-32% lower than the comparator WWTP systems. The median levelized cost of wastewater treatment using the PRR technology is 34-58% lower than the A
