By the 19th century, when Dickens satirised the Circumlocution Office, "red tape" was a sufficiently familiar trope to be used without further explanation.
Please note that while the approaches demonstrated here are highly simplified and would not be used without further refinements, they illustrate principles of CAD.
Biopolymers such as starch or cellulose as well as plant oils can be converted in one or few steps to a mixture of molecules that can be used without further separation for the manufacture of high tonnage end-products such as paper, paints, resins, foams, lubricants, and plasticisers, that do not require the use of isolated, pure molecules.
The excellent correlation between these measures demonstrates acceptable validity of the proposed methods, that the mixture does not contain harmful substances for the Polymer Electrolyte Membrane (PEM) fuel cells and that the obtained bio-H2 can be used without further purification.
The crushing process provided directly by the machine generates an even grade 96%<1515 cm of small particle sizes that can either be sold as secondary product (such as road base) or the material could also be used without further treatment for the reclamation process.
In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.
