Hi Anonymous,

As far as i know there is no manual recomending methods for disposal of used or unused RUTF/ RUSF. In a survey in 2018 UNICEF found there was no clear strategy among suppliers / users for disposal of packaging https://www.unicef.org/supply/media/4776/file/0900-Greening-Blue-take2-SustainableProcurement-RUTF-June2018.pdf  A quick review of references on google mostly suggest the packaging is often incinerated, although one source also suggeted disposal in a latrine. I couldnt find any references on the safe disposal of batches of unused expired product. In short this is a gap in the guidance.

At present it doesnt appear that there is an alternative environmentally friendly packaging that is economically viable although UNICEF and Nutriset indicate they are looking into modifications in packaging as part of the overall life cycle of these products ot reduce the environmental impact. 

This interesting article by ALIMA cites the recycling of RUTF packaging where 100kg of wasted packaging is converted ot 19L of fuel which is then used for other purposes. Similar initiatives are being explored to convert the used packaging into briquettes for contruction purposes.  https://alima.ngo/en/news/burkina-faso-plastik-project/.
