A process and an apparatus for the manufacture of biogas and a solids fraction from an organic waste feedstock is provided. The process involves thermal hydrolysis of the organic waste feedstock at a temperature from about 100 to about 220&#xb0; C., a pressure from about 5 to about 20 bars, for a period of time from about 15 minutes to 4 hours, to produce a hydrolysate. The hydrolysate undergoes anaerobic digestion at a temperature from about 25 to 60&#xb0; C., for a period of time from about 1 to 35 days to produce a biogas stream, characterized as having a methane content from between 55 to 75% by volume and a digestate. The digestate is separated into a solids fraction and a liquid fraction, and a portion of the solids fraction is recycled for further anaerobic digestion.
