Claim 12:
13. The process of claim 1, wherein the densified textile derived syngas composition stream has a switching variability that is negative, zero, or not more than 15%, wherein the switching frequency is at least 1 time every two years, and the switching variability is determined by the following equation:, %

where % SV is percent densified textile derived syngas switching variability on one or more measured ingredients in the densified textile derived syngas composition; and
Vt is the densified textile derived syngas compositional variability of a gaseous compound(s) using a feedstock comprising densified textile aggregates and a second fuel source; and
Vb is the densified textile derived syngas compositional variability of the same gaseous compound(s) using the same feedstock fuel source other than the densified textile aggregate, and where the feedstocks have the same fuel concentration and are gasified under the same conditions, other than temperature fluctuations which may autogenously differ as a result of having densified textile aggregates in the feedstock, and the variabilities are measured and satisfied against at least one of the following gaseous compounds (in moles):
a. CO amount, or
b. H2 amount, or
c. CO2 amount, or
d. CH4 amount, or
e. H2S amount, or
f. COS amount, or
g. H2+CO amount, or its molar ratio in sequence (e.g. H2:CO ratio), or
h. H2+CO+CO2 amount, or its molar ratio in sequence, or
i. H2+CO+CH4 amount, or its molar ratio in sequence, or
j. H2+CO+CO2+CH4 amount, or its molar ratio in sequence, or
k. H2S+COS amount, or its molar ratio in sequence, or
I. H2+CO+CO2+CH4+H2S+COS.
