A waste disposer comprising a primary dehydrating chamber, a grinding device, a secondary dehydrating chamber, and a storage chamber. The primary dehydrating chamber is adapted to allow waste to be heated therein to partly dehydrate the waste. The primary dehydrating chamber has: a first waste inlet for receiving the waste, a first vapor outlet for exhausting vapor from the waste, a drainage outlet for draining free liquid from the waste, and a first waste outlet for outputting the partly dehydrated waste. The grinding device is adapted to receive the waste from the first waste outlet and grind the waste to reduce the size thereof. The secondary dehydrating chamber is adapted to allow the ground waste to be heated therein to further dehydrate the waste. The secondary dehydrating chamber has a second waste inlet for receiving the ground waste, a second vapor outlet for exhausting vapor from the waste, and a second waste outlet for outputting the further dehydrated waste. The storage chamber is adapted to receive the waste from the second waste outlet and store the waste in the storage chamber.

A machine for distributing material from a package of compressed loosefill insulation material is provided. The machine includes a lower unit having a front panel. A shredding chamber is bounded on one side by the front panel and the shredding chamber receives compressed loosefill insulation material from a source of compressed loosefill insulation material. The shredding chamber including a plurality of shredders for shredding, picking apart, and conditioning the loosefill insulation material. A discharge mechanism is mounted to receive the conditioned loosefill insulation material exiting the shredding chamber and to distribute the conditioned loosefill insulation material into an airstream. A removable front access assembly covers a portion of the front panel of the lower unit and includes a control panel having a plurality of control devices. Removal of the removable front access assembly makes the plurality of shredders and the discharge mechanism within the lower unit accessible for inspection, replacement, or repair.

A method for recovering lithium from lithium ion battery scrap according to this invention comprises subjecting lithium ion battery scrap to a calcination step, a crushing step, and a sieving step sequentially carried out, wherein the method comprises, between the calcination step and the crushing step, between the crushing step and the sieving step, or after the sieving step, a lithium dissolution step of bringing the lithium ion battery scrap into contact with water and dissolving lithium contained in the lithium ion battery scrap in the water to obtain a lithium-dissolved solution; a lithium concentration step of solvent-extracting lithium ions contained in the lithium-dissolved solution and stripping them to concentrate the lithium ions to obtain a lithium concentrate; and a carbonation step of carbonating the lithium ions in the lithium concentrate to obtain lithium carbonate.

Fiberboard or chipboard is made by first comminuting vegetable starting material in a first comminutor into a stream of loose plant particles with silicate particles. Then, in a first classifier silicate particles of a diameter of less than 50 μm are separated from the plant particles of the stream. The plant particles remaining in the stream are then glue-coated, and the stream is pressed into fiberboard or chipboard.
