It's current state and use is minimal and inefficient, reduced to, on average, to the Genesis of Carbon Variants by (Manual) Compressor or to the Recycle of Cobblestone by (Manual) Compressor and Electric Press.

An example of this is this inefficiency is the Cobblestone Recycling through either Stone Chunks or Flint in the Electric Press.
If we disregard the prior need for the materials, the energy needed for the generation of Cobblestone through said Recycling Process is capped at the most efficient ratio of 40J during 1 second on Tier II while the generation "de novo" through the Igneous Processor is capped at 12J through out 3 seconds.

Therefore, I suggest into other to prioritize recycling over mass grinding and waste production, the output through either machinery is significantly boosted and/or the energy required for the Electric variant is drastically reduced.
