The present invention addresses the processing of waste and low-value products to produce useful materials in reliable purities and compositions, at acceptable cost, without producing malodorous emissions, and with high energy efficiency. In particular, the invention comprises a multi-stage process that converts various feedstocks such as offal, animal manures, municipal sewage sludge, tires, and plastics, that otherwise have little commercial value, to useful materials including gas, oil, specialty chemicals, and carbon solids. The process subjects the feedstock to heat and pressure, separates out various components, then further applies heat and pressure to one or more of those components. Various materials produced at different points in the process may be recycled and used to play other roles within the process. The invention further comprises an apparatus for performing a multi-stage process of converting waste products into useful materials, and at least one oil product that arises from the process.

What is claimed: 1. A process for converting a feedstock into at least one useful material, comprising:preparing a slurry from the feedstock, wherein the feedstock includes animal processing waste;heating the slurry to a first temperature sufficient to breakdown components of the slurry at a pressure above the saturation pressure of water in the slurry to produce a conditioned slurryreacting the conditioned slurry in a reaction at a second, higher temperature ranging from about 150° C. to about 330° C. sufficient to hydrolyze materials in the conditioned slurry to produce a reacted feed comprising at least one reacted solid product, and at least one reacted liquid product, the reacted liquid product comprising a liquid mixture of carbon-containing species and produced water containing solubles, the pressure in said reaction being at least at the saturation pressure of water in the conditioned slurry;separating said at least one reacted solid product, said produced water, and said liquid mixture from said reacted feed; andconverting said liquid mixture into at least one useful material.
