Hvy Duty CarbonExtractor is a technology that can be researched at the Carbon Proc Ctr in Tech Level 4. It costs 300 Food and 200 Carbon, and lets workers gather carbon 10% faster. Enhanced CarbonExtractor must be researched before it becomes available.

This is the final carbon-gathering technology, and should be researched quickly to ensure the flow of resources.

"At Tech Level 4, your carbon processing facility may be used to research an additional upgrade that speeds carbon collection even further. "
