An object of the present invention is to provide a method for producing recycled water, according to which when recycled water is prepared from waste water, chemical cleaning of a membrane can be significantly reduced and fouling of the membrane can be eliminated by substantially only washing with water. The above object is achieved by providing a method for producing recycled water, the method including the following steps (A) to (D) of: (A) subjecting waste water to an anaerobic treatment and an aerobic treatment which are carried out by microorganisms, the waste water having been discharged during a production process of a PHA; (B) subjecting treated water obtained in step (A) to pretreatment filtration performed by a membrane bioreactor method; (C) subjecting the treated water obtained in step (B) to an alkali treatment; and (D) filtering, through an ion removal membrane, the treated water obtained in step (C).

The present invention provides for passive V0C recovery in the fermentation process that does not affect or minimally affects the conditions within the fermentor vessel and does not affect or minimally affects the conditions within the headspace of the fermentor vessel itself while using the production of CO.sub.2 emitted during the fermenting process as the source of driving energy to move a portion of the gaseous/vaporous material in the headspace of the fermentor through an appropriately sized conduit to a chilled surface condensing device to condense the V0Cs (principally ethanol) for recovery and to exhaust the CO.sub.2 to the atmosphere or to recover the CO.sub.2 for other uses. The conduit from the headspace of the fermentor to the condenser is sized to provide a flow restriction in a selected range such that the headspace equilibria are not affected while allowing a portion of the gaseous/vaporous material in the headspace to move through the conduit in response to the generation of the CO.sub.2 during the fermentation process.

A process and/or system for producing biomethane, hydrogen, or fuel, fuel intermediate, and/or chemical product from the biomethane or hydrogen. The biomethane and/or hydrogen is produced in a process that converts biomass to biomethane. In certain embodiments, the biomethane production process includes anaerobic digestion, which produces biogas and digestate. Carbon-containing material (e.g., derived from the biomass) is stored and/or used as part of at least one carbon capture and storage process, where the carbon-containing material includes (i) carbon dioxide produced from the biomethane production process (e.g., produced from anaerobic digestion), and (ii) carbon-containing material obtained or derived from residue of the biomethane production process, and optionally includes (iii) carbon dioxide produced from the hydrogen production process.

The present disclosure provides methods for treating one or more grains in an ethanol plant or alcohol brewery, methods of drying, cooling, disease control of dried distillers grains with soluble (DDG), barley, or brewer's spent grain (BSG), and a system for treating one or more grains in an ethanol plant or alcohol brewery by these disclosed methods.

Embeddable extensions of the functionality of email and calendaring applications are described herein. An originating email and calendaring application formats meeting items to include extensible content, e.g., within the body field of the meeting item. Recipient email and calendaring applications receive the meeting items and, depending on whether they are configured to provide an extended functionality, will either deploy the extensible content item according to the extended functionality or present the extensible content item according to a standardized functionality. The body field includes the extensible content item according to the standardized functionality that is interpretable by configured clients to provide the extended functionality.
