The invention refers to a soap recycling device that recycles solid soap bar remnants into purified liquid soap or purified reconstituted solid soap bars, depending on a user's selected mode of operation of the device. The soap recycling device includes a heat source that melts the solid soap remnants, a UV emitter that sterilizes the solid soap remnants, and a directional valve that selectively delivers the molten soap fluid to a first receptacle capable of storing the soap in liquid form and delivering it for direct usage, for instance for hand washing, and a second receptacle where the molten soap fluid solidifies and turns into a reconstituted solid soap bar. The device includes a user interface that allows selecting the desired operation mode to either liquid or solid soap formation. The device according to the invention is compact and versatile.

A method is disclosed. The method includes providing a cleaning member formed from a consumable cleaning material and including a cavity formed by one or more interior walls of the cleaning member, inserting a cleaning member remnant through an aperture of the cavity formed at a first end surface of a first end portion of the cleaning member, providing and holding a fluid in the cavity holding the cleaning member remnant when the first end surface is facing upward, and attaching the cleaning member remnant to the one or more interior walls based on holding the fluid.

Method for purifying crude tall oil soap from black liquor, wherein a washing liquid is used, which washing liquid is either pH-regulated residual liquid from a tall oil producing processing step (180) or a pH-regulated aqueous solution of ash, wherein black liquor-containing crude tall oil soap is mixed with said washing liquid, and wherein the crude tall oil soap is then separated out from the resulting mixture. The method comprises the steps 1. performing a first coarse separation (120,130) of crude tall oil soap from said black liquor, so that a first crude tall oil soap fraction is formed; 2. mixing (140) the first crude tall oil soap fraction with washing liquid, so that a first diluted fraction is formed; and 3. performing a separation (150) of the first diluted fraction using a first centrifugal separator of purificator type, so that a second crude tall oil soap fraction is achieved. The second crude tall oil soap fraction comprises smaller contents of black liquor than the first crude tall oil soap fraction. The invention also relates to a system.
