1. A method for producing fuel from biogas comprising:
(a) providing biogas from a plurality of biogas sources, the biogas from each biogas source produced in a process comprising:
(i) collecting raw biogas from one of the biogas sources in the plurality, the raw biogas comprising methane and carbon dioxide;
(ii) optionally, subjecting the raw biogas to a partial purification to produce partially purified biogas, wherein the partial purification removes less than 75% of the carbon dioxide from the raw biogas;
(iii) filling a vessel with the raw biogas or the partially purified biogas to a pressure of at least 1500 psig;
(iv) transporting the filled vessel to a centralized processing facility by vehicle; and
(v) removing the raw biogas or the partially purified biogas from the vessel transported to the centralized processing facility;
(b) producing fuel in a fuel production process, the fuel production processing comprising feeding the biogas provided in step (a) to a biogas upgrading system, the biogas upgrading system configured to provide a compressed stream of carbon dioxide removed from the biogas; and
(c) providing carbon dioxide from the compressed stream of carbon dioxide for transport by vehicle, pipeline, or a combination thereof.
