Carbon

Carbon is a solid intermediate item used in several advanced production chains. It is produced by processing organic or extraterrestrial carbon-containing materials and serves as an input for recipes that convert between Carbon and Coal and for other specialized manufacturing paths. Carbon is not an energy fuel in the same way as Coal; it functions chiefly as a crafting intermediate in processing chains that require carbon feedstock.

Carbon can be obtained through multiple alternative processes:

• Burnt spoilage produces Carbon from Spoilage by thermal processing.
• Carbonic asteroid crushing produces Carbon and other outputs by crushing carbon-rich asteroids.
• Advanced carbonic asteroid crushing produces Carbon plus additional byproducts from a more efficient asteroid-crushing process.

Practical notes on production and conversion:

• Converting between Carbon and Coal is lossy. Even with optimal modules and setups, transforming Carbon into Coal and back results in a net loss of Carbon or Coal.
• The conversion processes consume other chemical inputs; specifically, Sulfur and Sulfuric acid are consumed in some Carbon/C oal processing recipes. Account for these additional resource requirements when designing production lines.
• Use the asteroid-crushing alternatives when available to increase throughput and byproduct yield; Advanced carbonic asteroid crushing yields more outputs than the base Carbonic asteroid crushing.
• Burnt spoilage provides a straightforward early or cleanup route to obtain Carbon from Spoilage, useful where waste streams exist.

Design considerations:

• Balance the entire loop of Carbon and Coal carefully; repeated cycling will reduce total resource mass and will also draw Sulfur and Sulfuric acid from your supply.
• Place Carbon production close to the consumers of Carbon to minimize belt or logistic overhead, especially when byproducts require immediate processing.
• Monitor Sulfur and Sulfuric acid stocks when running Carbon–Coal conversion chains, and integrate dedicated Sulfuric acid production if conversions are part of a sustained plan.

Carbon is a mid-to-late-game intermediate whose efficiencies depend strongly on chosen production methods and the availability of Sulfur and Sulfuric acid. Plan production lines with attention to net losses in cyclic conversions and prioritize the most efficient asteroid-crushing recipes when possible.
