An on-orbit recycling method for a buffer foam of a cargo spacecraft includes the following steps: mechanically cutting a shaped PU foam into foam micro-blocks, and putting the foam micro-blocks into a packaging bag for packaging, where the packaging bag is filled with a foaming adhesive; the foaming adhesive includes a component A and a component B, which are independently packaged in a two-component packaging bag; and the component A and the component B are separated by a film; and squeezing the film between the component A and the component B, such that the two components are fully mixed, foamed and expanded to finally burst the two-component packaging bag, where after the packaging bag is burst, the foaming adhesive expands into gaps of the foam micro-blocks; and in a microgravity state of space, the foaming adhesive expands and fills uniformly in all directions and fully infiltrates the foam micro-blocks.

A bottle shredder is disclosed. The bottle shredder features a bottle holder, sized to receive a plastic bottle, a wire cutter and bottle support, both of which are located below the bottle holder. The bottle holder is attached to a linear slide, which is capable of moving the bottle holder directly above a shredding apparatus. The shredding apparatus contains at least one feed roller operatively connected to a first motor, a spur gear, a bearing block, featuring at least one bearing, and at least one shredding blade operatively connected to a second motor via the spur gear and bearing block. Below the shredding apparatus is a finished shreds chute, which collects the post-shredded bottle parts.

The process (1) for the recovery of raw material from waste products comprises at least the phases of: supply (A) of one skein to be treated (3) composed of a harmonic steel fraction and a non-ferrous fraction; pre-treatment (F) of the skein to be treated (3) to separate the harmonic steel fraction from the non-ferrous fraction to obtain one treated skein (3b), comprising one step of mechanical separation (F1) of the harmonic steel fraction from the non-ferrous fraction; heat treatment (B) of the pre-treated skein (3 a) to obtain one treated skein (3b), the phase of heat treatment (B) comprising a step of inductive exposure (B1) of the pre-treated skein (3a) to one time-varying magnetic field, the step of inductive exposure (B1) being adapted to raise the temperature of the pre-treated skein (3 a) to one working temperature below 800 C.; post-treatment (E) of the treated skein (3b).
