- •
We analysed two upgrading options for enhancing sewage sludge stabilization.
- •
We performed techno-economic and environmental assessment of the two options.
- •
Intermittent aeration in post-aerobic treatment allowed efficient nitrogen removal.
- •
The two proposed upgrading options performed better than the reference plant.
- •
Environmental concerns relate to phosphorus and ammonia emissions.
