Sanitation Innovations for Humanitarian Disasters in Urban Areas
During emergencies in urban settings when space is limited for sanitation and the use of facilities is high, latrines fill-up quickly. WASTE, LSHTM and their partners aim to improve access to a safe sanitation system by: i) identifying, developing, and testing effective bio/chemical additives that convert household faecal matter into a harmless and non-smelling product and ii) prolong the lifetime of on-site sanitation technologies by identifying key characteristics in management and microbiological make-up that could slow the filling-up of latrines.

The project involves two innovative solutions to guarantee the access to a sanitation system during emergencies:
The use of bio/chemical additives to sanitise and stabilise faecal sludge, and;
Limit fill-up rates of faecal matter in on-site sanitation technologies.
The first innovation aims to sanitise and stabilise faecal matter by: defining the product (bio-additive) requirements in emergency situations; inventorying and short-listing existing bio-additives, and proofing the most promising solutions on real faecal matter.
The second innovation aims to develop a bio-additive that can promote rapid decomposition of faecal matter by: identifying pit’s characteristics to quick decomposition, identifying 100 latrines that never fill-up and sampling and analysing the contents of selected latrines.
What materials or research outputs are likely to be produced?
Set of requirements for bio/chemical additives to be applied in emergencies.
Inventory and short-listing of the most promising bio/chemical additives existing in the market.
Protocol to test the application of identified bio/chemical additives.
Field test report to prove the products’ applicability.
Set of parameters and criteria that define a good performing latrine.
Identification of use and management factors associated with increased decomposition.
Identification of bacteria, archaea, or enzymes suitable to be explored further as possible bio-additives.
