Assalamu Alaykum, I hope this reaches you in the best of health and eman.
My company and I are trying to setup our own slaughterhouse. So I would like to know before hand what are the rulings on dealing with the blood. Right now with our current slaughterhouse the blood goes down the drain. At our future slaughterhouse location that may not be possible due to regulations. We plan on collection the blood in 250 gallon liquid totes. Then the blood would be carried away to a land fill to be disposed of. However I have had a company contact me wanting to buy the blood. Please see link below for the their website for more information about what they do with the blood. Other options we have to deal with the blood is to sell it to be used in dog food or to be used by fisherman to help catch fish. All three of these ways we could sell the blood to help bring down overhead costs thus making the halal meat more affordable. Please let me know what is and what is not ok to do as far as the shari rulings go regarding the blood of goat and lamb.

الجواب وبالله التوفيق
It is impermissible and haram to sell blood regardless if it is from a goat or lamb. Therefore, one should collect it in a container and have it discarded, or ask a company to take it, without you making any money through this transaction.
واللہ اعلم بالصواب
