Resumo

This paper call attention to increasing ratio of oxygen depletion from atmosphere besides the global worries about CO2 concentration increase in the atmosphere. It highlights the big mistake in considering Carbon Capture and Storage, CCS, as a way to reduce the increasing concentration of CO2 in the atmosphere. As a hypothetical example it presents an existing pseudo-ecosystem of manufacturing that has real windows of opportunity to increase its share in the global materials production industry, even in highly industrialized countries. As a suggestion and example the author point out possibilities to almost fulfill the proposed simple rules to be considered inside an ecosystem of manufacturing utilizing the production of steel via biomass versus fossil coal. A relevant and difficult rule to be attained in a quasi-ecosystem of manufacture is to be a near zero atmosphere oxygen depletion integrated process. The industrial alternatives that utilizes the actual photosynthesis are the ones that can reach a higher ecosystem of manufacture’s index. It is presented an ideal integrated steelmaking process where the gaseous, liquids and solid residues generated in one part of the system are or can be utilized in the other parts of the same system. A potential ecosystem of manufacture to produce primary iron is illustrated in the paper.
