Evaluation of a closed-loop sanitation system in a cold climate: a case from peri-urban areas of Mongolia

Dear All,

Following study has just been published at the Journal of 'Environment and Urbanization'.

Abstract: This study examines a closed-loop sanitation system (CLSS) in the ger
areas (informal peri-urban settlements) of Ulaanbaatar, Mongolia in order to evaluate
system feasibility and to identify the future prospects of CLSS as an alternative to
conventional sanitation and drainage options. Results show that the CLSS concept
is well understood and accepted by users and that services are being scaled up. Over
50 per cent of respondents used CLSS technologies during both winter and summer,
testifying to the potential for scaling up these technologies and services. Moreover,
all users responded positively in their evaluation of the emptying services. Despite
some problems and challenges, the system proved to be feasible, replicable and
acceptable in the study area. It is recommended that the entire CLSS approach be
tested through scientific validation to convince more communities, government
and other stakeholders about scaling up the system beyond the study area for better
health, environmental conservation and resource recovery.
