Claim:
1. A co-firing system for combusting coal and processed biomass in a coal combusting apparatus with less adverse by-products, comprising: a first chamber of a coal combusting apparatus configured to pulverize a coal feedstock comprising a processed biomass/cleaned coal blended compact aggregate that comprises at least 10 wt % of a coal having a sulfur content of at least 50 wt % less than that of the content of sulfur in the coal before it passed through a coal cleaning sub-system and at least 10 wt % of a processed biomass from a processed biomass system and to feed the pulverized cleaned coal feedstock into the coal combusting apparatus in a first concentration of feedstock; a second chamber of the coal combusting apparatus configured to pulverize a processed biomass pellet feedstock from the processed biomass system and to feed the pulverized processed biomass pellet feedstock into the coal combusting apparatus in a second concentration of feedstock with the weight ratio of the first concentration to the second concentration between 1 to 9 and 9 to 1, wherein the processed biomass system is configured to make processed biomass from unprocessed organic-carbon-containing feedstock that includes free water, intercellular water, intracellular water, intracellular water-soluble salts, and at least some plant cells comprising cell walls that include lignin, hemicellulose, and microfibrils within fibrils , the processed biomass system comprising:
