Where it has been introduced, CLTS has been integrated with other development initiatives. Besides ending open defecation, the focus is on a more comprehensive package which includes wastewater management, solid waste disposal, overall hygiene and more. The approach has also been modified in some countries to ‘School-led Total Sanitation (SLTS)’, whereby schools are the prime drivers in achieving ODF status. This has widened the spread of CLTS and its impact, both among adults and children. Plan, Water Aid and UNICEF have become important disseminators and champions of CLTS. Today, it is present in many countries in Asia, Africa, Latin America, the Middle East and Africa. In sub-Saharan Africa, it has taken root in 28 countries and gained the support of decision makers and professionals, who have recognised it as a successful, cost-effective approach and have issued a declaration to urge governments to take more decisive steps to ensure ODF environments among local communities.
- Re: How should we call the excreta-derived product of a composting toilet or a UDDT? Do we need a new term? - by: hajo July 31, 2016thanks Dean, very good explanations when read together with your previous posting. ciao Hajo @Elisabeth: what is difference between 'reply' and 'quick reply'? Has been asked earlier by a user but possibly not answered.
- Re: How should we call the excreta-derived product of a composting toilet or a UDDT? Do we need a new term? - by: goeco July 30, 2016I would suggest that our use of the term vermicomposting refers to the process of worms digesting organic material into humus. Eventually compost must become humus, but my use of the term "compost" refers to a wider range in states of organic matter decomposition. Humus being a subset of compost, a later stage whereby the organic C has stabilised. […]
- Re: How should we call the excreta-derived product of a composting toilet or a UDDT? Do we need a new term? - by: hajo July 30, 2016Dean, then vermi-composting is actually not 'composting' but 'making humus', thus we use the wrong expression??!! ... or it is a bit of compost after being feces/organic matter and before being eaten by the worms??
- Re: UDDT versus Pour Flush (with vermi-composting) versus ???: which are sustainable sanitation technologies and systems for peri-urban areas in Africa? - by: hajo July 30, 2016Dear Dean, I expressed in my previous post (11.4) the expectation that the vermi-composting would reduce the emptying cycle of the pour flush twin pits from 2 years to up to 5 years. So there we agree. Soaking away urine, black water or grey water takes place with most of the on-site systems which are currently in use here: pit latrines soak away urine; (pou […]
- Re: What do we know about odorous gases from composting toilets (or from composting in general)? - by: goeco July 30, 2016Both humus and compost are derived from organic matter. For our purposes, humus could be defined as having less "active" carbon than compost. It still contains organic C but this C is more stable (something to do with half-lives and mineralisation rates of soil organic carbon) and because humus isn't a ready food source for organisms to respir […]
