Renewable ressources

[crazy_fab]

Hi guys I am working on my base on a mindcrack server, my personal challenge is to limit at at maximum the use of quarry to feed my development.
I am quitte advanced and I try to find renewable and efficient way of producing the different resources. I have already 8 iron golem farm which produce quite some iron(sadly I still consume faster than that but what can you do). I also have a complicated setup feeding 4 boiler with biofuel which in turn produce enoug lava to keep 16 centrifuge busy(that's one cooper every 8 second 1 tin every 16 and so on). I have a wither spawner I could get coal and diamond from( for now I don't have the need but I could set it up).
I m looking for new project to create ressources out of thin air. I know van do a lot and I am breeding some, but I am afraid it will be slow and I want to us different method for everything if possible.
For redstone I am looking a redwheat and gregtech crop harvestor (althought I have some excited bee I could use if else fail).
So my question is do you guys know any other mean of getting ore in a renewable fashion.(especially lead I am short off for now)

For the lead you can always centrifuge silver (from electrum) or get it from leaded comb.

I might do that but I am trying new process each time and it's quite a loosy process from 2 silver to 1/4 of lead. But if my electrum keep increasing I'll probably end up centrifuging silver.

Pigman Spawner -> Gold

Bees or IC2 crops for just about any base product with considerable work/tinkering. IC2 crops would likely need significant farms to produce enough, bees would require alveary(s) to keep up.
