There has been quite a lot of discussion around which industry buildings produce what and how they all interact so I thought I would try to capture it here.

Generic (specialised industry zones) extractors and DLC industry extractors all produce exactly the same 4 products:

• Ore
  
• Oil
  
• Logs
  
• Grain (Called Crops in the DLC)

It is at the processing step that things diverge.

Specialised generic industry processing plants produce:

• Ore -> Coal
  
• Oil -> Petrol
  
• Grain -> Food
  
• Logs -> Lumber

DLC industry processing plants:

• Ore -> Glass, Metals
  
• Oil -> Petroleum, Plastics
  
• Grain -> Flours, AnimalProducts
  
• Logs -> Paper, PlanedTimber

DLC Factories take the DLC primary/intermediate products and produce luxury products:

• DLC Primary/Intermediate -> LuxuryProducts (Unique Factory Products)

Finally, generic industry NON-SPECIALISED acts a bit like factories from the DLC where they take the intermediate products and produce Goods.

• Coal, Petrol, Food, Lumber -> Goods

But they also have a trick, they can take the DLC intermediate products as well:

• Glass, Metals, Petroleum, Plastics, Flours, AnimalProducts, Paper, PlanedTimber -> Goods

They only have one storage buffer and happily fill it with either their primary (non DLC input) or their secondary (Industry DLC) input.

The inputs also come in semi matched pairs eg:

• Lumber and (Planed Timber or Paper)
  
• Food and (Flours or Animal Products)
  
• Petrol and (Petroleum or Plastics)
  
• Coal and (Metals or Glass)

In table form:


To help decode the confusing labels on the warehouse storage selector:


It should also be noted that generic industry zones are actually "districts" whereas Industry DLC zones are actually "parks". This means you can zone the same region to be both an Industry DLC area and a specialised generic industry area and produce both types of intermediate products from your processing facilities.
