The invention relates to a method for recycling cellulose acetate-containing material, such as a filter tow starting material which consists of cellulose acetate or at least has cellulose acetate. The method has the following steps: supplying a filter tow starting material to a pelletizing press; and pelletizing the filter tow starting material in the pelletizing press in order to convert the filter toe starting material into pellets, wherein the converted pellets have a higher density than the supplied filter tow starting material, and the filter tow starting material, the pellets, and/or intermediate stages of the material are cooled at least temporarily during the pelletizing process.

A panel and a method for manufacturing thereof where the panel includes a first layer comprising a first blend of paper fragments and plastic fragments; a second layer comprising a second blend of paper fragments and plastic fragments, wherein the paper fragments and plastic fragments of the second blend are coated with an adhesive; and a third layer comprising the first blend of paper fragments and plastic fragments, wherein the second layer is disposed between the first layer and the third layer, and wherein the first layer, the second layer, and the third layer are combined to form the panel using heat and pressure. In another embodiment, the paper fragments and plastic fragments of the first blend, not the second blend, are coated with an adhesive.

The present application discloses the impurity removal method of silicate solid waste and its application. This method includes: (A) Heat and melt the silicate solid waste to be treated to form the melt, and stratify the melt during the reduction reaction; (B) An upper melt component obtained by the stratification is subjected to magnetic phase-induced crystallization to obtain a ferromagnetic solid; (C) The ferromagnetic solid goes through magnetic separation, and what remains is the solid waste after impurity removal. This impurity removal method can effectively reduce the main impurity content of the solid waste including iron oxide. The removed solid waste can be directly used for the preparation of high value-added materials such as insulating ceramics and micro-crystal glass.

A hydrolyzer infeed system for supplying waste material to a hydrolyzer in a continuous manner, the infeed system comprises an infeed chamber, an inlet gate separate a chamber inlet from a chamber outlet, a ram disposed to reciprocate within the infeed chamber and compress waste material against the inlet gate when the gate is in the closed position and configured to push the compressed waste material past the inlet gate into a hydrolyzer when the gate is in an open position, an actuator operably coupled to the ram and configured to move the ram between retracted and extended positions. In one aspect, the ram extends past the inlet gate when in an extended position. In another aspect, an actuator position sensor operably coupled to the actuator generates a position signal representative of a position of the actuator and a corresponding position of the ram at all positions between the retracted ram position and the extended ram position.
