If we drop a weighted shot and then tie in, we’ll shoot the weighted shot to the surface with a lift bag when we’re all secure.

How about instead of plastic jugs, the divers take some bags of trash from the boat and release it into the water. The trash floating to the surface would let the boat know they were tied in.

how is this even a thing?
I’ve also been on boats that still release cups which will be recovered and used for the next dive

A latex condom would seem to be biodegradable and easily seen.

Seems like the obvious thing to do would be to do the thing divers do when they want a signal at the surface.... bring a reel and a small closed bottom DSMB. Tie in, shoot the bag and either tie off the reel to the line or take it up.

Yes, the used condom can be easily recovered from the gut of a dead sea turtle.
The styrofoam cups have been around a long time. Part of the problem is you need to retrain the dive community from using something that is very reliable, very cheap and stupid simple. It does have the down side of not being environmentally friendly. But how many plastic water bottles are carried on boats every dive? Only 10% are actually recycled, the rest end up in land fills, incinerators or the environment. How about the amount of fuel burned by boats ferrying us out to the dive site. A gallon of gas converts to 22 lbs (10 kg) of CO2, when you include the production and transport.
I stopped getting lids and straws for my sodas. There are some organic substitutes to to styrofoam , I wonder if any of them will work.

{scratching my head} I agree with @CuzzA . It isn't difficult at all and this is what we do too. The 1st diver down ties into the wreck. Once set, he shoots a bag (smb) on a reel to the surface and hooks off the reel near the boat tie in.
The last diver on the wreck agrees to release the tie in slip knot and set it free. He then grabs the reel (The SMB is still inflated and not touched by the boat). He then drifts off the wreck with the SMB so the captain knows where to follow him. Every wreck diver knows how to shoot an SMB with an OPV. And if you suck at tying in to a wreck you can use 2 different colored SMB's which all the tech divers do to indicate what kind of problem they have.
P.S. If you are using any part of a chain or anchor to tie in, that's your main problem to get rid of.

Not sure I follow you here. Captain drives over the wreck which is, let's say.. 130' deep. Crew drops shot line with a 40lb chain attached to one end and a tuna ball on the other. Boat comes back around and a diver goes in at the tuna ball, follows the shot line down to the wreck, Finds a solid spot to tie the chain into the wreck. At this point you have a diver at 130' who has been working depending on how far he has had to swim or drag the chain to find a good spot to tie. You also have a boat full of divers waiting to get in the water.
The "Shot Line" is actually the anchor line. After the crew spots the bottles, the boat is pulled up along the tuna ball and it's pulled up on deck with the Shot (anchor) line attached (and the other end now tied to the wreck). The tuna ball end is cleated and was-lah .. we're tied in.
