Hydrofluoric acid can be neutralized with sodium bicarbonate and poured down the drain, and has the advantage of leaving no genomic material or bones for forensics. Bodies are surprisingly hard to get rid of and often seem to come back to life at the most inconvenient times.

The fumes are nasty, though. I hate working with that stuff.
If I had to break down a large animal carcass beyond all recognition, I’d heat it in a strong lye solution until everything was liquid except bone and teeth, then dissolve those remains in heated sulfuric acid. No fumes, no systemic toxicity.
I was staying at a friends house and I tend to stay up much later than normal folks. One night I stepped outside to smoke and I found their garage door open. It tuned out that something was opening the door for about and hour every night.
I don’t recommend leaving the door to the garage unlocked is what I’m saying.
I always liked my remote unlock, but my wife thought it was stupid. Then she realized how much easier it was to load/unload three small children and accoutrement into a minivan when she could unlock and lock the doors remotely.
It just occurred to me that I think auto-open van doors are silly - but now I realize that for those with small children they are a logical improvement to remote lock/unlock.
So, no one’s at all hesitant to have a garage door that can be hacked? And the OP is leaving their interior door open for tradespeople, where all it would take is a remotely unlocking the garage to gain access to the house… I’d be wary of that, myself.
Here it is, from the first post:
Yes, Stanley / Black & Decker owns Kwikset, Baldwin, and Weiser. There’s a confusing overlap of which Baldwin locks have Smartkey cylinders, or can be keyed the same as Smartkey by old-style changing the internal pins, and which can’t be keyed the same by any means.
Cheaper than Kwikset? Yikes, that’s cheap. 
The tech I never thought I’d embrace is sous vide cooking with an app-driven device. Using it tonight to cook dinner, actually.
A microwave.
Yeah, now I use it all the time.
Now just wait until you get a smart key. As long as it’s somewhere near the car (like in your pocket/purse) you never have to touch it. Grab the handle and the door unlocks, push a button on the door handle and it locks. You can even set it (or at least I can on my car) so it automatically locks as you walk away. When I used to wear a jacket in winter, I kept the key buried in an unused inside pocket. It would go months without seeing the light of day. Now I just keep it in my pants pocket, but still, I never think about it since I can lock/unlock the doors and start the car without needing to do anything more than having it with me.
My wife never saw any reason for a Google home device, but they were giving them away cheap, so I picked one up. It sat in the box for months until I showed her she could use it to call up her favorite radio station. Now she uses it all the time for weather and other things. She especially liked that it replies when you thank it.
Instant Pot. A brilliant bit of technology that makes killer pulled pork in 2 hours. Ridiculous and delicious.
Cordless drills. Trying to do projects with a corded drill now would be tragic.
Feeding it to the hogs seems tidier.
I have spent summers on a hog farm and I found it anything but tidy. You’re welcome to it.
Yeah, I’ll pass. I’ve visited a hog farm. But i also used hydrofluoric acid for a job. I’ll pick the hogs over that.
So how much lye would one need for about 150 pounds of let’s call it waste material?
Need answer fast?
It seems silly at first blush, but it is amazing how nice it is to be able to sit on the couch, and just say “Hey, Google, play One-Punch Man on Living Room TV, volume 100%”, and… voila.
ETA: Weird, Discourse took out my first (partial) quote of Dewey_Finn, and replaced it with a full quote of the OP…
Not that fast. I have some planning to do. (Disclaimer: “this is for a novel I’m writing”)
I don’t know what’s optimal. I would probably use a standard 50% by weight solution, and I’d use a roughly equal volume of that to biomass. So that would be about 75 pounds of lye in 75 pounds of water.
I suspect you could get by with a lot less, especially if you had the option of adding more heat and more time, but I’ve never had to.
The security protocols setting up the garage door app seemed pretty robust. I’m sure the Russian government could hack it, but if someone wanted to break into our house, there are easier ways than trying to hack the garage door app. We have plenty of glass windows and doors that could be smashed in a second. Plus, we can set our security alarm (we rarely do, but we could) so that opening the door from the garage to the house would set off the alarm.
Japanese-style robo-bidet seat for the loo. I mean, I’ve successfully wiped my own arse for most of my life, normal bidets are nice and all - I’ve certainly enthusiastically used them when in e.g. the Middle East - but what could all this tech possibly add…
I am now reluctant to go out for extended periods lest I have to shit somewhere that doesn’t have one.
OK, slight hyperbole, but I’m definitely never again living in a house without one.
Robot vacuum. We turn that little sucker on when we leave the house and it goes under the bed, and other hard to reach places. Even when the room looked fine, it fills up with dog hair and other debris every time.
