A new IRC paper explores some contributions being made by honey-sucker tanker operators — that renders a small-scale sanitation service informally and within the private sector — on waste (faecal) extraction and, in some cases, reuse. Operating outside the legal framework of waste management, this paper provides preliminary insight into the limitations and potentials of the ‘honey-sucker business’ as a sanitation service model, based on selected experiences in Bengaluru (India).

- Re: Vermi-Trickling Filters for Sewage Treatment (looking for help to design) - by: Benno March 18, 2018Hi Kris …BSF larva will work great and are voracious feeders, although, IMO, there is a bit of a yuk factor to them them that can take some getting used to, which is probably why they changed their name to BSFLs instead of maggots. I guess probably no different than the yuk factor of composting humanure, which we seem to have now come to love. As Dean mentio […]
