--A device and method for dewatering a mass of material and a method and system for recycling a biogenic material. A vertical press has a press space formed between a tool provided with openings and a press plunger movable relative thereto. Conveying means convey the mass of material from a feed side toward an opposite discharge side. The press space is laterally confined by opposite side walls but is not confined in the direction of the feed side and the discharge side. A biogenic material is converted microbially and/or enzymatically into gas and fermentation residues in a fermentation plant and the latter are dewatered by means of a vertical press to such an extent that thermal utilization is made possible.--

A hand-operated screw press for users to press cannabis flower or isolated trichome heads without an air compressor, hydraulic unit or solvents used in the process. A digital load cell is provided, as is a full color LCD touch screen display for showing and recording force in real time. A mechanism for detecting the end point of a process is also provided. A recipe representative of heat plate temperature, time of operation, pressure ramping, capacity of the screw press, type of raw material, or mass of raw material can be created and stored for use on any suitable rosin press machine.

A process for the separation of electrolyte from the carbon in a solid carbon/electrolyte cathode product formed at the cathode during molten carbonate electrolysis. The processes allows for easy separation of the solid carbon product from the electrolyte without any observed detrimental effect on the structure and/or stability of the resulting solid carbon nanomaterial.

A double-hinged food press for extruding foodstuff through a grate and operational by hand while held aloft or placed on a work surface. An upward-curved plunger handle, combined with a receiver handle designed to rest on the surface, positions the press for the operation. Rollers enable the grate to be snapped smoothly over risers into and out of recesses in the receiver without undue wear and resulting loss of integrity. A raised lip of resilient material surrounding a plunger face further ensures a tight fit between the plunger and receiver cup. Resilient material between the plunger face and the hinge barrel of the grate ensures a tight fit between the two. Hinge pins may be removed by the user for replacement of the grate. Bosses can extend from the receiver unit for support on the surface to assist in operation of the press. An attachable paddle can be used to collect extruded material and to scrape it from the grate.

A press for processing organic waste has two plungers. Preferably, the plungers have rectangular cross sections. The two plungers are mounted in the press such that they are perpendicular to each other and have partially overlapping stokes. The press has walls that partially enclose a pressing chamber. The pressing chamber is as wide as one plunger on one side, and as wide as the other plunger on another side. In operation, one of the two plungers is used to optionally load organic waste into the pressing chamber, to partially enclose the pressing chamber while the waste is compressed, and to eject compressed waste from the pressing chamber. The other plunger is used to compress waste in the pressing chamber whereby a pressate is produced through perforations in a wall of the pressing chamber. The other plunger may also partially enclose the pressing chamber while compressed waste is ejected.
