Back in topic, my early game strategy to produce some juice is a skeleton farm, bonemeal a dark room (deployer + transoposer), filter to get rid of all the "non-biofuelable" stuff, plantballs from seed and biomass generated. After that, when I get the armor and the enchantments (and maybe a jetpack) to easily survive in the nether, blaze farm.
Always keep in mind that you can get a tier 5 soul shard just killing 10 mobs and wasting a couple of diamonds in the process, no need to kill 1024 mobs or to find 5 spawners.
