TL;DR: Although only a simple qualitative HPLC method was used, colour removal, toxicity and TON removal all support its usefulness in analysing biotreatment of azo dyes.

TL;DR: In this paper, it is demonstrated that biomethane can be produced at a cost which is competitive with liquid bio-fuels and fossil fuels within the UK within the Renewable Transport Fuel Obligations.

TL;DR: Dewatering investigations suggested that the acid pretreated WAS required 40% less cationic polymer addition to achieve the same cake solid content, and optimisation of acid dosing was performed considering digestibility benefits and level of acid required.

TL;DR: Combined anaerobic-aerobic treatment was used to treat a simulated textile industry wastewater (overall HRT 1.8 days). The azo dye (PROCION Red H-E7B) and starch concentrations were varied in a series of 1-week experiments to determine the effect of starch:dye ratio on COD, BOD and colour removal as discussed by the authors.

TL;DR: The approach could mitigate for possible regional excesses, and substitute conventional high-impact products with bio-resources, enhancing sustainability withinacircular economy.
