A method and device for extracting oil from food waste is disclosed. Food waste is introduced into an elongated cylinder that is immersed under hot water. A drive shaft is actuated that simultaneously presses the food waste against an interior wall and moves the food waste through the cylinder. The content of the cylinder is subjected to steam treatment using a steam inlet in the cylinder. The combination of hot water, steam treatment and pressing recovers a high content of oil from the food waste.

A fuel tank system is disclosed that includes a fuel tank and a first fluid flow path between a gas space in the fuel tank and outside of the fuel system. A gas separation membrane is disposed with a first side in communication with the first fluid flow path and a second side in communication with a second fluid flow path. A fluid control device is in communication with the second fluid flow path and is configured to provide fluid flow from the second fluid flow path to a liquid space in the fuel tank or to outside of the fuel system. A prime mover is disposed in communication with the second fluid flow path, and is configured to move fluid on the second fluid flow path from the second side of the separation membrane to the fuel tank liquid space or to outside of the fuel system.

Disclosed herein is an apparatus (10) for remediation of a site contaminated by an oil spill. The apparatus (10) comprises a porous capsule (12) encapsulating material (14) for sorbing oil. The material (14) comprises granules of an at least semi-open cell polymeric foam, the granules being less than 10cm3 in size. Ingredients from which the polymeric foam is formed comprise acrylonitrile butadiene rubber as a major constituent thereof by weight.

A fat conditioning apparatus includes a conditioning vessel enclosing a conditioning chamber and a displacable plug. The conditioning chamber is bounded on one end by the displacable plug and has a variable volume that is a function of the position of the plug within the conditioning vessel. The apparatus has utility in a fat conditioning method, wherein the conditioning chamber contains a harvested fat emulsion. A washing liquid is injected into the conditioning chamber and mixes with the harvested fat emulsion, thereby displacing the plug in an outward expansion direction and expanding the variable volume of the conditioning chamber. The resulting mixture of harvested fat emulsion and washing liquid is stratified in the conditioning chamber into a contaminant-lean fat fraction and a contaminant-rich remainder fraction. The fat fraction, which is substantially free of the remainder fraction, is recovered from the conditioning chamber as a desired product of the method.

A diffuser baffle for use in an in-line wastewater grease interceptor. The diffuser baffle lies within a grease collecting chamber between the inflow and outflow of a grease interceptor. The diffuser baffle has an open bottom which is sized and shaped respectively to fit into the grease collecting chamber. The diffuser baffle has an end operatively connected to the inflow opening to permit wastewater to flow into the body through the open bottom. The baffle has a downstream end which includes a deflector portion to deflect a wastewater stream in a direction generally into the grease collecting chamber. The body also includes a number of apertures to permit the deflected wastewater stream to pass through the baffle and into the grease collecting chamber, where FOG will separate before waste water exits the chamber through the outlet baffle.

A skimming apparatus with a pivot arm and a drive follower on the pivot arm that guides a belting to facilitate precise placement of the belting for efficient skimming.

A surface containment system to contain liquid contaminates escaping from a vessel, the containment system having in one example: a water and oil impermeable barrier liner positioned below the vessel; a perimeter wall surrounding the vessel, the perimeter wall extending vertically from the ground surface and supporting a portion of the barrier liner so as to form a containment reservoir; at least one fluid conduit through the barrier liner, the fluid conduit having a filter configured to retain contaminates and configured to allow water to pass by way of gravity from the reservoir through the impermeable barrier; the perimeter wall formed of a plurality of wall panels connected by way of struts each having a vertical component, a base component anchored to ground.
