  • Is biological wastewater treatment eco-friendly?
  • Several wastewater treatment processes include physical, chemical and biological techniques. During biological treatment, waste water is treated using micro-organism instead of chemicals. Hence, these methods are relatively more eco-friendly. However, biological treatment organic pollutants but not all kinds of pollutants (Hussain et al., 2021).
  • Does India support composting of organic waste generated from urban regions?
  • As described in previous sections, several schemes supporting the composting of organic waste generated from the urban regions of the country have been launched and promoted by the Government of India. Despite all the policies and schemes framed by the government, their implementation on the ground level is still a major challenge.
  • How effective are ex-situ bioremediation treatments for organic pollutants?
  • Other treatments have shown less remediation efficiencies for various organic pollutants ranging 16–75% after 5–90 days of treatments by various ex-situ methods (Table 2). Table 2. Ex situ bioremediation: slurry phase (bioreactor) and solid phase (biopiling, land farming, composting, biofilter) treatments performance.
  • Which microalgal models are used for bioremediation of organic and inorganic pollutants?
  • The popular microalgal models utilized for bioremediation of organic and inorganic pollutants includes Chlorella, Chlamydomonas, Scenedesmus, Spirulina, Phormidium, Oscillatoria, Botryococcus, Desmodesmus, Nodularia, Arthrospira, Cyanothece, etc. (Baghour, 2019; Priyadharshini et al., 2021).
