Abstract: Provided is a system and method for producing and purifying biodiesel. In particular, the system comprises a tandem arrangement of at a modular biodiesel reactor and a continuous flow separation and purification unit. The system can further comprise an evaporation unit that is placed between the biodiesel reactor and the continuous flow separation and purification unit.

Abstract: An entirely water-based, energy self-sufficient, integrated in-line waste management system is provided for comprehensive conversion of all organic fractions of municipal and wider community waste to fuels suitable for use in transportation, with all solid residues converted to high nutrition compost. The system is based on a combination of pre-treatment, involving alkaline hydrolysis and saponification; three-way separation of the pre-treated waste into different streams that are each directed to suitable further processing including fuel production; which includes biodiesel generation in a continuous-flow catalytic esterification unit, and anaerobic digestion to produce methane or other small molecule biofuel. Remaining solids are converted to compost in a quasi-continuous process.

Abstract: A continuous-flow steam explosion reactor for pretreatment of organic material for further processing to value-added products is provided. The reactor comprises a loading section, a high-pressure retention section with an adjustable-speed conveyor, a pressure relief section and a discharge section. The reactor comprises means for providing steam into at least said high-pressure retention section and means for providing pressurized gas (e.g. air) to further boost pressure. The loading section is suitably configured to transfer material from ambient pressure to the high-pressure retention section while retaining high pressure and temperature in the high-pressure retention section, and the pressure relief section configured to transfer material from the high-pressure retention section to a discharge section while retaining high pressure in the high-pressure retention section.

Abstract: An apparatus for the separation of solid component, heavy and light density liquid components of a slurry, comprising a decanter section comprising a screw conveyor enclosed by a decanter house and a centrifuge section comprising a disc centrifuge. The centrifuge section is enclosed by a centrifuge house, the decanter section and centrifuge section are separated by an intersection comprising a stationary impeller for transmitting liquid from the decanter section to the centrifuge section. The screw conveyor, decanter house and centrifuge house are rotatable around a central axial shaft. The decanter section an axially arranged inlet and a solid material outlet, the centrifuge section comprises an axially central first liquid outlet for lighter liquid and second liquid outlets for heavier liquid. The second liquid outlets can be arranged on an end plate of the centrifuge house, with the radial distance of the second outlets from the central axis being adjustable.

Abstract: A method for automatically cleaning fish such as cod comprises gripping the fish and subsequently cutting it open, first transversely behind the head from the belly of the fish and subsequently in its longitudinal direction along the belly, and finally removing the entrails.
