Processes and systems for recovering products from a corn fermentation mash. In one example, a process for recovering products from a corn fermentation mash can include separating ethanol from a fermentation mash to produce a whole stillage. The fermentation mash can be derived from a ground corn product milled from a plurality of corn pieces. The plurality of corn pieces can include whole corn kernels, fragmented corn kernels, size-reduced corn kernels, milled corn kernels, or a mixture thereof. Greater than 25 wt % of the ground corn product can have a particle size of greater than 105 μm and greater than 80 wt % of the ground corn product can have a particle size of 425 μm or less, as measured according to AOAC 965.22-1966. The process can also include separating the whole stillage to produce a fiber rich portion and a filtrate.

The present invention provides a system for the capture and purification CO.sub.2 and a purification unit for said system, wherein said purification unit comprises: a first filter having a first container and a first filler material; a second filter having a second container and a second filler material, downstream of said first filter; a third filter having a third container and a third filler material, downstream of said second filter, said third filter having, additionally, a heating element thermally coupled to said third filler material; and control means of said heating element; wherein said first filler material is silica; wherein said second filler material is zeolite; and wherein said third filler material is a metal-organic framework modified with activated carbon.

A system and method for directly transferring fermentation carbon dioxide by-product to a greenhouse are disclosed. A three-way valve receives the carbon dioxide by-product from fermentation vessels in a fermentation facility, and either directs the carbon dioxide by-product to a proximately located greenhouse or diverts the carbon dioxide by-product to the external environment based on greenhouse carbon dioxide concentration levels that are monitored by sensors communicatively coupled to the valve. For example, if the concentration levels are below a threshold, the sensors may transmit a signal to the valve to direct the carbon dioxide by-product to the greenhouse; otherwise, if the concentration levels are at or above the threshold, the carbon dioxide by-product may be diverted to the external environment. The threshold may be a carbon dioxide concentration level determined to be optimal for photosynthetic efficiencies based on a number and/or type of the plants contained within the greenhouse.

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.
