Question Summary:
Feeding Haram to animals

Question Detail:

 
This is with reference to my query in Fatwa # 30335.
The garbage I intend to compost can contain lots of haram items like dead animals (lizards, rats and possibly even cats/dogs) and feces etc.
Regarding worm composting: I might try to minimise such items, but they will still be left inside. Worm composting can still be carried out even if meat etc. are present in the garbage, even though it is better not to put such items in the worm bin.
Regarding Bokashi composting: It is different from ordinary composting. A huge variety of items, including meat, can be composted using Bokashi, not just the items you mentioned. Secondly, in Bokashi, we deliberately add microorganisms to the garbage (using a powder or liquid as carrier) whereas in ordinary composting the microorganisms naturally occuring in the soil perform the composting.
For more information on Bokashi composting, please refer to my previous query (fatwa # 30335) as well as the links I provided earlier.

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
If the garbage you intend to compose contains Haram items such as dead animals, faeces etc. then it would not be permissible to utilize these Haram items and feed them to the worms.[1]
Shari’ah has prohibited the feeding of Haram to anyone, whether human beings or animals or creatures.
