This patent describes the process of producing liquid oils from organic waste materials, which comprises: mixing an oil-based carrier with organic waste material selected from the group consisting of organic garbage, raw sewage, sewage sludge and waste paper. The waste material contains at least about 10 weight percent water. The amount of oil-based carrier present is sufficient to permit the mixture to be a more readily flowable material that the corresponding waste material free of oil carrier. The flowable material is pyrolyzed at elevated temperature and pressure to produce the liquid oils. 17. The process of producing liquid oils from organic waste materials selected from the group consisting of organic garbage, raw sewage, sewage sludge, and waste paper, which comprises: mixing an oil-based carrier with organic waste material, the waste material containing at least about 10 weight percent water, the amount of oil-based carrier present being sufficient to permit the mixture to be more readily flowable material than the corresponding waste material free of oil carrier, pyrolysing the flowable material at a temperature of 700/sup 0/ to 950/sup 0/F. and a pressure of 700 to 2,500 p.s.i. to produce the liquid oils, and thereafter passing the heated, substantially continuous stream through heat exchange means to recover heat and to transfer it to an upstream portion of the substantially continuous stream.
