Abstract: A method for storing harvested photosynthetic active horticultural produce includes, between harvesting and consumption of the harvested photosynthetic active horticultural produce, packaging the harvested photosynthetic active horticultural produce for moisture retention, and exposing the harvested photosynthetic active horticultural produce to green light emitted from a monochromatic LED and having a peak wavelength of between about 500 nm and about 580 nm, inclusive.

Abstract: A method for storing harvested photosynthetic active horticultural produce includes, between harvesting and consumption of the harvested photosynthetic active horticultural produce, exposing the harvested photosynthetic active horticultural produce to green light and/or to blue-green light. A device for storing harvested photosynthetic active horticultural produce includes a casing defining an interior volume, and a cooling mechanism for cooling the interior volume. At least a first LED is supported by the casing. The first LED is configured to emit green light to the interior volume, or is configured to emit blue-green light to the interior volume.

Abstract: A decontamination apparatus includes a housing defining an interior volume and having at least a top, a bottom, a left side, a right side, a front, and a rear. The top, the bottom, the left and right sides can each have a set of low-voltage UV-C light emitting diodes that face towards the interior volume. The front can include a front opening and the rear can include a rear opening. The apparatus can include a front door that is openable and closable to block the front opening, and a rear door that is openable and closable to block the rear opening, to allow objects to pass through the interior volume from the front to the rear. Alternatively, a belt conveyor system can pass through the interior volume from outboard of the front opening to outboard of the rear opening to allow objects to be conveyed through the interior volume.

Abstract: A process and process line is provided for recovering heat in the form of cleaned warm water and residual bitumen from oil sand tailings produced during an oil sands extraction process. The process includes removing at least a portion of the coarse solids from the oil sand tailings to produce a reduced solids tailings fraction; separating at least a portion of the bitumen from the reduced solids tailings fraction to produce a bitumen fraction and a warm water and fines fraction; and removing at least a portion of the fines from the warm water and fines fraction to produce cleaned warm water and a concentrated fines fraction. The cleaned warm water can then be reused in the oil sands extraction process.

Abstract: A process for extracting bitumen from oil sand, comprising: mixing oil sand with process water to produce an oil sand slurry containing bitumen, sand, water and entrained air; conditioning the oil sand slurry; optionally flooding the conditioned oil sand slurry with flood water to dilute the slurry, if required; introducing the slurry into a primary separation vessel wherein separate layers of primary bitumen froth, middlings and sand tailings are formed; removing a portion of the primary bitumen froth from the primary separation vessel and recycling the portion of primary bitumen froth to that step of the process upstream of the primary separation vessel to join and mix with the feed stream moving to the primary separation vessel; and thereafter retaining said feed stream in said primary separation vessel to produce primary bitumen froth.
