IRW-PRESS: Rock Tech Lithium Inc.: Zero-Waste Umsetzung:  Rock Tech Lithium, GP Papenburg und
Schwenk Zement arbeiten bei der kommerziellen Verwertung von Lithium-Nebenprodukten enger
zusammen

Guben, 30. Januar 2023 - Rock Tech Lithium Inc. (TSX-V: RCK; OTCQX: RCKTF; FWB: RJIB; WKN:
A1XF0V) (das Unternehmen oder Rock Tech), GP Papenburg Entsorgung Ost GmbH (Papenburg oder GP
Papenburg) und Schwenk Zement GmbH & Co.KG (Schwenk oder Schwenk Zement) haben in Vorbereitung
der kommerziellen Nutzung von Nebenprodukten aus der Lithiumproduktion im Januar eine
Absichtserklärung unterzeichnet. Ziel ist es, bis Ende 2023 die zuvor vom gemeinsam
gegründeten Deutschen Lithiuminstitut (ITEL) erarbeiteten Prozesse in die Praxis zu
übertragen und damit industrieübergreifend ressourcenschonender zu produzieren, wodurch
auch CO2 eingespart werden könnte.

Auf dem Weg seine Zero-Waste-Strategie umzusetzen, plant Rock Tech mit den Schwergewichten der
Bauindustrie GP Papenburg und Schwenk Zement direkte Abnahmeverträge für Neben-produkte zu
erörtern. Vorbereitend vereinbarten die drei Unternehmen deshalb in einer
Absichtserklärung konkret zu untersuchen, wie industrieübergreifende Prozesse im
kommerziellen Maßstab gestaltet werden müssen.

Ziel ist es unter anderem Alumosilikat aus der Lithiumaufbereitung ressourceneffizient in der
Baustoffindustrie einzusetzen. Dadurch könnte Rock Tech sonst anfallende Abfälle vermeiden
und zusammen mit GP Papenburg und Schwenk die Emission von CO2 industrieübergreifend
reduzieren. Gleichzeitig eröffnen sich den beiden Baukonzernen Optionen für die Produktion
neuer, innovativer und nachhaltiger Produkte.

In unserem Ausgangsstoff, dem Spodumen, ist Lithium in mineralischer Form in Alumosilikat
eingebunden, welches bei unserer Lithiumkonvertierung als Nebenprodukt entsteht. Dadurch, dass das
Aluminosilikat bereits bei der Lithiumkonvertierung kalziniert wird, kann bestenfalls dieser
Prozessschritt auf der Seite der Zementindustrie entfallen, wodurch dort Energie und damit auch CO2
Emissionen eingespart werden können., erklärt Martin Adorni, Rock Techs Leiter für
Prozess- und Technologietransfer, die Besonderheit des Verfahrens.

Das Projekt wird vom Deutschen Lithiuminstitut (ITEL) wissenschaftlich betreut. Die
vielversprechenden Vorergebnisse sollen nun bis Ende 2023 weiterentwickelt werden. Sollten sich
diese Ergebnisse bestätigen, könnte sich für Rock Tech ein bisher bei der
Lithiumgewinnung anfallender Abfallstrom mit angestrebten Abnahmeverträgen ökologisch und
ökonomisch gewinnbringend nutzen.

ÜBER ROCK TECH

Rock Tech ist ein Cleantech-Unternehmen, das es sich zur Aufgabe gemacht hat, Lithiumhydroxid
für Elektroauto-Batterien herzustellen. Das Unternehmen plant, Lithiumkonverter direkt dort zu
bauen, wo es seine Kunden benötigen, um Transparenz in der Lieferkette und eine
Just-in-Time-Lieferung zu gewährleisten. Um die drängendste Lücke hin zu einer
sauberen Mobilität zu schließen, hat Rock Tech eines der stärksten Teams der Branche
zusammengestellt. Das Unternehmen hat sich strenge ESG-Standards auferlegt und entwickelt einen
eigenen Aufbereitungsprozess, der effizienter und nachhaltiger sein soll. Rock Tech plant, das
nötige Rohmaterial aus seinem eigenen Mineralienprojekt in Kanada zu beziehen, aber auch von
anderen verantwortungsvoll produzierenden Minen. In den kommenden Jahren wird das Unternehmen
voraussichtlich auch Material aus dem Batterierecycling beziehen. Das Ziel von Rock Tech ist es,
einen Kreislauf für Lithium zu schaffen. www.rocktechlithium.com
