the imperium does have some weaponry that would remove bio-matter for tyranids to consume, like vortex weapons, but atomizing tyranids will still leave bio-matter to consume, it just becomes atom sized matter. the same with the life eater virus, which i think only works on planets and not in space, it may destroy life but the charred remains of what's left is still organic matter, it's very dead matter but still organic matter and still able to be consumed once the virus itself has burnt-out.

and yes tyranid weaponry and munitions also require resources, but tyranids can provide those resources from themselves - every tyranid that is killed, as well as every enemy that tyranids kill, can be consumed and recycled at a formidible rate. the point being that technological weaponry, in fact every space-faring species of the milky way, requires the consumption of finite resources whereas tyranid weaponry, indeed the entirety of the tyranid species, can be sustained as long as there is life, and that life can simply be tyranid life.

as for kamikaze attacks and extremely long-range weaponry, they may work for a while but the hive mind can easily counter such tactics by creating new bio-forms - this has been seen time and again where something works against tyranids and then, seemingly out of the blue, new bio-forms are encountered which nullify that which was working. i agree that vortex weaponry would most definitely work in removing bio-matter, but again, it wouldn't be long before the hive mind would realise the threat of such weaponry and then create countermeasures.

it doesn't matter the level of technology, number of soldiers, quality of soldiers, availability and replenishment of resources etc, against the tyranid species because it will always be a war of attrition, and attrition is what tyranids do best as they have unmatchable numbers and all the, recycleable, resources of war immediately at hand. therefore the only tactic i believe would truly work against tyranids would be the use of daemons since they could fight and 'die' without leaving any matter to be consumed, and the daemons themselves don't require any resources, as such tyranids would eventually lose this war of attrition, but, once again the tyranids could have an answer to such with 'the shadow in the warp', depending on how strong it becomes as the hive mind continues to awaken.

i maintain my position that no species has the capability of surviving against tyranids on their own. an unprecedented galactic alliance could possibly defeat the tyranids, but to be assured of victory the aid of the chaos gods' daemons would be needed.

and yeah, abaddon would be a smear on a wall seconds after emps laid his eyes on him :)
