The present invention is a process of recycling plastics based on eliminating the need to pre-sort different plastic materials and using physics to separate plastic particles based on the gravitational weight of those particles. Plastics are grounded down into very small pellets using a uniform pressure cylinder with dimples. Then, the small plastic pellets are separated using a float-sink method. Using the float-sink separation method, the plastics can be lifted and organized by density and by gravitational weight from lower densities to higher densities using different gases or liquids with different gravity weights or densities.

A process for trichome separation from plant matter deploys water slurry agitation and/or dry sieving to produce a mixture of solid trichomes and similar sized plant debris. The plant debris in each separate fraction is then removed by gravity filtration in a dense inert liquid, which is preferably a salt or brine solution. The desirable trichomes or trichome glands float on the dense liquid, while the undesirable vegetative matter sinks to the bottom of the brine containing vessel. The trichomes are readily removed and washed before further processing.

A system and method of scheduling tasks, comprising receiving activity and performance data from registers or storage locations maintained by hardware and an operating system; storing calibration coefficients associated with the activity and performance data; computing an energy dissipation rate based on at least the activity and performance data; and scheduling tasks under the operating system based on the computed energy dissipation rate.

A cryogenic processing system includes a cryogenic fluid source, and an auger, which includes an auger vessel containing at least one screw assembly. The screw assembly includes a flighting and a hollow shaft radially inward of the flighting. The shaft is in fluid communication with the cryogenic fluid source and includes one or more nozzles for dispensing cryogenic fluid within the auger vessel.

An apparatus, composition and method for recycling of a material, such as, for example, unhardened concrete. The apparatus includes a storage tank for storing a recycling composition to be applied to the material to be recycled and a control unit configured to control release of the recycling composition from the storage tank.

A method of extracting bitumen from oil sands having a transition temperature at which the oil sands solidify includes forming formable oil sands into pellets and cooling at least a surface of the pellets sufficiently to prevent the pellets from aggregating; cooling the pellets to below the transition temperature; fracturing the pellets to release the bitumen from the oil sands while maintaining the temperature of the pellets below the transition temperature; and separating the bitumen from the oil sands in a separator.
