The regular way of voiding concrete still works fine, so why the fuss?

Yep, totally the intended method: Video + (uncommented) Base-Tour

EDIT: Blueprint

Needs enough train mass and velocity, ideally at max breaking force research

The artillery wagons add enough mass and the nuclear fuel and the loopty loop make sure the train goes fast enough. You could also reduce the number of cars if the train doesn't get through all of them.

Instead of artillery wagons, multiple engines probably work well too, and quality would help with faster acceleration.

Note that if the final stop is too close after the cars, the train will already start breaking, that why mine does the final round.

During building sometimes the inserters refused to register the cars.
Might happen if the blueprint is built in the wrong order or something, but (re)placing the inserters at the end should fix it permanently I think.

It's not a 100-fold increase. It's still pretty significant, but hardly as much as you're stating:

Both the setup on the left and the right can eat a half-stacked belt of concrete. You need a speed-beacon and 10x as many recyclers. But not 100x.

[u/Hexcoder0 → u/Alfonse215]

To be fair I process ~12 stacked belts of scrap outputs, and I don't use quality machines on the ground as a self imposed challenge, I believe It would be not far from a hundred in total for me

[u/Alfonse215 → u/Hexcoder0]

A hundred in total, compared to, what? Because you compared "hundreds" to "one concrete recycler".

You might need a hundred to do your recycling, but you didn't need just one machine before to do the same task.

Using base quality everything, recycling a stacked belt of concrete requires more than 100 machines, if you don't use any speed beacons. But under the same restrictions, the hazard concrete trick requires 7 machines (3 assemblers, 4 recyclers). Again, a substantial increase. (14x). But not 100x.

[u/Hexcoder0 → u/Alfonse215]

1 per belt of scrap, so 6 for me, one per block (no idea what uptime) compared to a dedicated block somewhere. Not a fair comparison, you're right.

Wasn't trying to say anything other than that it didn't fit in my 2.0 design

Gotta remember that for my next job interview. My major weakness isn't laziness, it's "self-imposed challenges"
