In case you missed this, IWA is granting (limited time) free access to a selection of recent papers to celebrate this year's World Toilet Day.

"To contribute to this important conversation, IWA Publishing have compiled a collection of recent relevant papers that will all be free to access from 13th November - 1st December 2017."

iwaponline.com/cc/world-toilet-day-2017-featured-collection

The accessible papers are:

• History of sanitation and hygiene technologies in the Hellenic world
• Limited services? The role of shared sanitation in the 2030 Agenda for Sustainable Development
• Bidet toilet seats with warm-water tanks: residual chlorine, microbial community, and structural analyses
• The development of an onsite sanitation system based on vermifiltration: the ‘Tiger Toilet’
• Types and distribution of improved sanitation technologies in sub-Saharan Africa
• In-toilet disinfection of fresh fecal sludge with ammonia naturally present in excreta
• Inactivation kinetics of indicator microorganisms during urea treatment for sanitizing finished compost from composting toilet
• Blue Diversion: a new approach to sanitation in informal settlements
• Effective faecal sludge management measures for on-site sanitation systems
• Dry sanitation concepts with inspiration from nature

Hope that might be of use since some of those topics are already heavily discussed here on the forum (though I did not manage to access the last paper on the list actually; might be a glitch).

Cheers
