The use of the dynamic respiration index to predict the potential MSW-leachate impacts after short term mechanical biological treatment

- We aimed to describe leachate impact reduction after short-term full scale MBT process.
- The dynamic respiration index (DRI) was used to measure leachate impact reduction.
- Leachate impact was measured after 1 year in landfill reactors.
- Short-term MBT getting a DRI < 1000 mg O2 kg VS−1 h−1 greatly reduced leachate impacts.
- COD, BOD5 and total heavy metal reduced of −70%, −81% and −16%, respectively.
