Disposal of spent molasses again

Hi everyone,

just wanted to open this question up again, and see if anyone has more info on sewer disposal for dunder. I've enjoyed reading all the other posts relating to this topic, but still have a few questions.

Does anyone pretreat their dunder so that it can then be sent to the sewer? (and then to the water treatment plant obviously)

Anyone using some type of filter on the dunder to remove solids and/or BOD?

Anyone drying out the sludge, left over from the treatment process, and using it for something? Sell it for fertilizer?

Thanks a ton

John

Wow, nice idea! How does the nursery pick up hundreds of gallons of dunder per week? Do you pump it into big plastic tanks, and then they pick up the tanks? Seems incredible that they could do this. What do they use it for anyway?

Add lime to the dunder (or other stillage) to bring it to neutral ph. Then it is safe to dispose through the sewer system, to use as compost or to use as animal fodder.

We fill plastic totes and the owner of a local nursery comes to get them. I don't know if they dry the dunder before use, but he loves it for the nitrogen and dead yeast.

If you do use it as animal fodder - don't feed it to sheep! They're sensitive to copper and you could poison them.

Where are you located? We operate in a large ag centered midwest state and we have absolutely zero waste streams that we do not make money on other then packaging we substandard recycling and absolute trash..... Organic farmers and chem industry can use everything you produce (heads tails stillage etc) you just need to get creative in finding the right people
