We earlier documented, through reports of Japanese research, that Carbon Dioxide can be captured and used as a raw material in the manufacture of useful plastics.
We also documented that the United States Department of Defense, through proxies, holds US Patents on the technology to recycle Carbon Dioxide into liquid fuels.
Herein, we document that a US chemical company, Monsanto, was issued, fifteen years ago, a United States patent on the use of Carbon Dioxide to manufacture urethane, much as described in the reports of Japanese research we posted to you.
Excerpt as follows:
"Preparation of urethane from polyamine and carbon dioxide
Patent number: 5371183
Filing date: Nov 16, 1992
Issue date: Dec 6, 1994
The present invention provides a process for preparing urethanes and carbonates from an amine or an alcohol, carbon dioxide and a hydrocarbyl halide. The amine or alcohol is reacted with carbon dioxide in a suitable solvent system and in the presence of an amidine or guanidine base, to form the... (urethane).

Our US Government has officially known for fifteen years that Carbon Dioxide can be productively recycled into a very useful, and carbon-sequestering, plastic.
That, in addition to the USDOD patents, held by proxies, on the recycling of CO2 into more fuels.
Yet, a decade and a half after issuance of the patent enclosed herein, our coal industries are still threatened with extortions like Cap-and-Trade, and Geologic Sequestration.
