For Global Handwashing Day 2012, this Weekly issue contains a literature review of 2012 handwashing studies that was compiled by the Global Public-Private Partnership on Handwashing. The review summarizes studies on the health impacts of handwashing, handwashing behavior, hand contamination and provides recommendations for implementers of handwashing programs.
- Re: Sustainable Decentralized Wastewater Management in Developing Countries (AIT, Thailand) - by: denniskl December 18, 2014Hi Daniel, Very interesting - and as a non-techie, Thammaratt's system does seem to be very similar, although maybe the thermophilic septic processing part is different? Can you explain the volumes that can be processed - I see mention of 800 students and 4 units, so can obviously cope with 200 students per day, but what is the volume limit per unit per […]
- Re: Closed loop recycling of flush water through ABR and Constructed Wetland? - by: denniskl December 18, 2014Chris yes it does seem sensible to re-use blackwater as toilet flush greywater (after on site processing) in a continual loop, topped up as required from rainwater collection systems, other greywater diversions or mains as the case may be. How much treatment and to what level of pathogen kill is required for this type of re-use? 100% or lower? I guess the qu […]
- Re: Questions on Faecal Sludge Management (calorific value of faecal sludge using bomb calorimeter), Bangladesh - by: BJWard December 18, 2014Hi Progga, We recently published a paper where we measured the calorific value of chars made from fecal sludge, and used the ASTM method D2015 (Standard Test Method for Gross Calorific Value of Solid Fuel by the Adiabatic Bomb Calorimeter). The ASTM method is here: law.resource.org/pub/us/cfr/ibr/003/astm.d2015.1996.pdf I've also attached the paper so t […]

- Re: Toilet certification - by: jkeichholz December 18, 2014Again, I see a certification mainly as a marketing instrument - and many potential customers certainly aren't interested in waste management in order to decide for a system they buy and install in their premises. As a customer, I am interested in issues like costs, design, use and so on. From a scientific perspective though, I also prefer a certificatio […]
