社員紹介
大きなアイデアには、優れたチームが必要
Geo40チームには、再生可能エネルギー、鉱物、冶金、鉱物処理、鉱山、機械・土木工学、化学、製品開発の各分野にまたがる多様なスキルが含まれています。
私たちの業績は、社員のスキル、エネルギー、コミットメント、そしてコラボレーションによる効果を反映しています。
当社は、地熱流体から低炭素・高品質のコロイダルシリカを持続的に大規模に回収した世界初の企業です。
この成果は、私たちが蓄積してきた幅広い経験によるものだと考えています。 研究室からパイロットプラント、実証プラント、そして最終的にはモジュール化された商業プラントへと、段階的な開発プロセスを通じてスケールアップすることで、技術的・経済的リスクを抑制しています。
大規模なリチウム直接回収プラントの建設に成功する見込みはいつ頃か、という質問をよく受けます。 シリカ回収の技術とは異なりますが、全く同じプロセス、同じディシプリンで行っています。
チーム紹介
今回は、その一部をご紹介します。
Robert Reweti
Plant Operator
Tena koe,
Ko Rapata Reweti toku ingoa
Ko mokopuna te tupuna Tahu Matua
Ko Ngati Tahu te iwi.
Hello my name is Robert Reweti and I am a direct descendant of our tribal Tipuna – Tahu Matua.
I have been employed with Geo40 Ltd for last two years as a Plant Operator sharing a special relationship between Tangata whenua and Geo40. This has provided me with opportunity to return back to the whenua for employment and advocating the wellbeing of our tribal lands.
Since completing my Environmental Management diploma in 2014 I have previously worked with our iwi towards reconstituting our tribal standing. I have valued the understanding and aroha Geo40 engages in with our people and taking on board four concepts of relationship being Economic, Environmental, Social and Indigenous values.
Tena kotu, tena kotu ,tena kotu katoua.

Isabela and her partner Frederik have one young child named George. When Isabela is not with them, she loves to head out for a swim in the lake or in the ocean.
“Extracting minerals with minimal environmental impact is what has motivated me to join the Geo40 team.”
Callum Ward
Product Development and QA Manager
Callum graduated from the University of Canterbury with a BSc in Chemistry, focussing on physical and inorganic chemistries.
Callum has been with Geo40 since its inception and has enjoyed seeing the process come to fruition and all the learnings along the way – from concept, to lab scale, to pilot scale, to demonstration scale, to the current commercially successful Ohaaki Plant.
An avid problem-solver who relishes the opportunity to contribute towards developing world-first technologies. Callum leads quality control to ensure all batches are produced consistently and meet customers specifications. He also assists R&D with experimental design to help develop new products and enhance existing products already on the market.
Callum is well supported by his fiancé Amber and kept amused by his two young children Everett and Peyton. Outside of work, Callum can be found enjoying the Taupo outdoors with his family and dog Odin.

ジョン・ワース
CEO兼マネージングディレクター
John Worth
CEO and Managing Director
Sustainably and profitably recovering future minerals from geothermal fluids is a very unique challenge, and John notes that, “the opportunity to take a nascent set of technologies and to develop a team to appropriately reward the belief of our shareholders is exciting indeed.”
John has worked extensively in energy across geothermal, wind, wave and solar disciplines and holds bachelors and masters degrees in engineering and management and has undertaken post-graduate and executive studies at Oxford, Harvard and Auckland.
He is a Chartered Engineer, contributes to a number of boards, and in his spare time coaches junior rugby, swims and surfs and is an occasional surf lifeguard.
