E-waste, PCBs & critical materials

Waste electrical and electronic equipment is a complex urban mine: printed circuit boards, displays, LCD panels, components, conductive thin films and strategic metals. Value is often locked in fine assemblies, soldered components, bonded layers or very thin coatings. XCRUSHER has already been applied to these materials to physically liberate valuable fractions, including ITO-containing LCD panels and metal-rich printed circuit boards.

A liberation step before extraction

In e-waste, valuable metals are not directly available. They are dispersed in boards, conductive layers, solders, components, films, glass or polymers. In LCD panels, indium is present in ITO, a very thin conductive layer deposited on glass. In printed circuit boards, value is carried by metallic tracks, solders, components and certain precious or critical metals. Before any chemical or metallurgical extraction, these fractions must first be liberated from their support. The industrial bottleneck is not only metal extraction. It is making the metal accessible.

The limits of global shredding

Conventional shredding reduces size, but often mixes high-value and low-value fractions. It can disperse precious metals into fines, dilute conductive layers, contaminate polymers and complicate downstream steps. For materials such as LCD panels or printed circuit boards, value depends on the ability to separate layers, components and metallisations without turning the whole material into an indistinct mixture.

The XCRUSHER approach

XCRUSHER acts as a physical liberation pre-treatment. The platform delivers a pulse in a liquid medium to generate a pressure wave capable of acting at interfaces: component / board, metal track / substrate, ITO layer / glass, casing / board, metal / polymer. The objective is not to chemically extract the metal inside the reactor. The objective is to detach, liberate and concentrate valuable fractions to prepare downstream processes: sorting, separation, hydrometallurgy, pyrometallurgy, bioleaching or another recovery route.

Available visual proof

1. LCD panels, ITO & indium

XCRUSHER has been applied to LCD panels to liberate the conductive ITO layer deposited on glass. The interest is to concentrate the indium-tin oxide containing fraction into a usable particle-size range, rather than processing the entire glass / polymer / film / functional-layer assembly indiscriminately. Available photos will illustrate: panel separation · fractions obtained after treatment · concentration of the ITO layer · the potential for indium recovery.

2. Printed circuit boards & metals

XCRUSHER has also been applied to printed circuit boards to detach, fragment and liberate metallic fractions. The interest is to prepare a more readable material for downstream recycling routes by better separating components, tracks, supports and metallic fractions. Available photos will illustrate: boards before treatment · fractions after selective fragmentation · metal liberation · separation between polymer supports, substrates and metallic fractions.

Three families of use cases

1. Printed circuit boards & PCBs

Printed circuit boards concentrate components, copper tracks, precious metals and a composite substrate that is difficult to separate. The issue is not only to shred a board. It is to detach components and liberate metallisations without unnecessarily dispersing valuable fractions. XCRUSHER brings a physical interface-separation route upstream of downstream recovery of copper, gold, silver, palladium, tin or other metals depending on actual composition.

2. Phones, small devices & batteries

Small electronic devices combine casing, board, battery, connectors, displays, polymers and metals. A physical dismantling step can separate key sub-assemblies before more targeted treatment of rich fractions. The challenge is to avoid applying the same treatment to the whole mass and to concentrate energy on high-value or risk-specific parts, such as electronic boards or certain batteries.

3. LCD panels, ITO layers & indium

LCD panels contain conductive thin films, including ITO, deposited on glass. Indium is present in small quantities, but it is strategic. XCRUSHER has already shown interest on this family of materials: liberating and concentrating the conductive layer to prepare downstream indium recovery.

What XCRUSHER brings

Physical interface liberation

Detaching layers, components, tracks or metallisations from their supports.

Pre-concentration of valuable fractions

Directing metals or functional layers into more usable fractions.

Reduction of indiscriminate shredding

Avoiding the transformation of the whole material into a difficult-to-process fine mixture.

Preparation for downstream processes

Producing fractions better suited to sorting, separation, hydrometallurgy, pyrometallurgy or other recovery routes.

Visual proof

Using available photos of ITO / indium and printed circuit board trials to show the physical reality of the separations obtained.

Examples of materials: printed circuit boards · component-rich PCBs · mobile phones · smart cards · contactless bank cards · LCD panels · ITO-coated glass · small electronic devices · fractions containing copper, gold, silver, palladium, tin, indium or other critical metals depending on the case.

Positioning: XCRUSHER is positioned upstream of extraction processes. The value is not only in the metal. It is in the ability to liberate it, concentrate it and direct the recovered fraction to the right downstream route. In e-waste, XCRUSHER brings a physical reading: identify interfaces, detach components, liberate metallic layers or tracks, then prepare usable fractions.

Each e-waste family must be assessed according to its actual composition, level of prior dismantling, presence of batteries or hazardous components, particle-size distribution and selected downstream route. XCRUSHER does not claim direct chemical extraction inside the reactor or guaranteed recovery of all metals.
