I've met and spoken many times with the enginner who invented the first pig killing apparatus in an abattoir (probably in the world, but certainly in the UK) using Nitrogen gas

He's an ex Olympian canoeist - and he lives and works in Ipswich UK - where his invention and innovation is used in many many areas

He's real - you can meet him if you wish. He runs a little engineering workshop and when I knew him - he trained one or a few canoeists heading for the Olympics

for pigs - they basically just get drowsy and fall asleep ---------- not so with Co2

If you head to the UK - I can put you in touch and you'll get a little education
