What to do with waste water from bubble hash washes

[Exzaction]

I am curious what people are doing with waste water from washing bubble hash? We recycle after washes when doable but have always just pumped ours down the drain or onto various plants outside the lab when finished. We have a California environmental inspection upcoming and although they havent had a problem with our processes on prior inspections I wonder if they could someday bring up issues with terpenes going down the drain. What are my fellow washers doing?

We drink it, still plenty of flavor left over and its full of nice constituients, cannabinoids aint the only good part of the plant!

Some worthwhile reading through a few of the referenced posts in here:

Hash water waste

Just wondering what other hash makers opinions are on reusing the same water for multiple washes i don’t feel right running through 100 plus gallons of water just to wash a couple thousand grams plus for me its much easier too get two cans down to temp and keep them that way rather than starting fresh every pull

Making use of ice hash process waste

We have a tenant in our facility making ice hash and rosin. I’m watching a huge amount of biomass hitting the garbage bin at around 10-15% THC still in the waste. Is there any viable process to use this for extraction as it comes out of the Ospreys? I was thinking BHO may work but I haven’t found any threads specific to this and if water saturated biomass would release all it’s moisture into the extract or not. Is this at all viable, or any other method for this waste?

Sounds great.

The waste biomass makes excellent fertilizer. The water probably would too.

Water extraction……you just need the know how…
Then when that is done, hydrothermal liquifaction of remaining biomass.

I would have thought it had plenty of terpenes? Aren’t some water soluble?
Regardless you could filter, centrifuge and distil it to recover all components (or figure out what is there).

How has your experience been with using the water for fertilizer? I have around 140L of bubble water left and im planning on using it for fertilizer on and outdoor field.

Also all the water has been stored in a warm room so it has some mold in it.

Let me know your opinion im happy to hear it!

Honestly, I have only used the biomass as fertilizer, which works very well, so I am only guessing about the water. It may aid the composting process when added back to the waste biomass.

We wash a lot of material and usually go thru a couple hundred gallons water per day. Seems it’d be quite hard to drink or enema 100 plus gallons of water per wash day lol.

I hadn’t seen one of those threads yet, thank you @DapperDabMan. A membrane seems interesting to remove the volatile compounds from the water but then I would need to figure out how much permeate vs discharge there is and what to do with the concentrated discharge.

I agree @Autumn_Ridge_Hemp that spent biomass makes an excellent input for a compost pile. In my head it should have minerals available in the proportion already used by cannabis plant. I hadn’t thought about using the water back into the pile. Will try that on our next attempt.

@moronnabis I researched hydrothermal liquifaction. Some seriously high temps and pressures compared to anything else in our lab. What a cool process but I don’t think its possible at small scale.

It seems that I need to better quantify what exactly is in the spent wash water. Spoke with our lab and I should have terpene and cannabinoid analysis back sometime next week. Will update this once I get results.

@Exzaction :
Well If I can get permission to share some info…I’ll let you know.
Quite a bit is done with Parr reactors…get an old GC with a very good thermal controlled oven…drill a hole in top and slip Parr reactor in……at least you can experiment in static reactors.

[Growgrowtony]

Thanks, I still have around 5kg of frozen bio mass that i was gonna use for a bho run. Maybe I could use it.

Will run some tests & share how the water works as fertilizer

It’s great for your garden even just your regular old vegetable garden. My tomatoes love wash water. But I have to admit I am team recycle your water wether you are building your own recycle kit (press club has good instructions for building one)
or you can splurge on a recycle kit from lowtemp

Filter and purify the water, get a bottle/can filler, and sell it for a premium as “Terp Water”.

I say that tongue and cheek, but when I see some of the products out there, I question if that might be more profitable than the hash itself…

[SubstituteCreature]

Nah nah nah you gotta think headier so you get those big ‘Grateful Dead fan that grew up and got a job but still spends way too much money on weed stuff’ bucks.

I was thinking more of a lifestyle brand that targets young people who waste money. The crowd who buys 2mg gummies and overpriced seltzer.

Call it TRP WTR or something. Promote it as a health product, or an enviromentally conscious thing.
