Aluminium is the most abundant metal in the earth’s crust. Approximately 75% of aluminium ever produced is still in use today as it can be recycled endlessly without compromising any of its unique properties or quality. Aluminium’s lifecycle provides significant benefits through recycling, saving 95% of the energy it would take to make new aluminium metal. More information on recycling may be found here. Recycling aluminium has five steps: Step 1: Collecting Scrap There are two categories of aluminium scrap: New Scrap New Scrap is surplus material that arises during the manufacture and fabrication of aluminium products, up to the point where they are sold to the final consumer. For example, off cuts of aluminium sheet or extrusions are considered new scrap. Sometimes, this new scrap can be safely recycled by aluminium smelters as its composition is known. Old Scrap Old Scrap is material that has been used by the consumer and subsequently discarded. For example, used beverage cans, window frames, electrical cabling and car cylinder heads are all considered old scrap. Aluminium smelters are unable to safely accept this old scrap as its composition is usually unknown and it can be contaminated. Scrap aluminium is also collected from the community – from households, scrap merchants, local and regional authorities, etc. Step 2: Sorting Scrap The scrap is then sorted – grouping all coated (painted or lacquered) aluminium together, and grouping all uncoated aluminium together. Paper, plastic and other non-aluminium recycling needs to be removed. Step 3: Crushing The sorted aluminium is then crushed into bales – by compacting the aluminium scrap, it reduces freight, storage and handling costs Step 4: Remelting Uncoated scrap is loaded directly into a large furnace called a remelter, where it is heated at high temperatures and turned into molten form. If the scrap aluminium is coated, it is processed through a gas fired rotary furnace to remove any coating and then transferred to the remelter. Step 5: Casting The molten aluminium is cast at a temperature of just over 700°C to form ingots

アルミニウム 2026年3月 ― 圧力から世界を揺るがすサプライショックへ 2026年3月は、アルミニウム市場が関税や環境規制に直面するだけの月ではありませんでした。世界全体が「ブラックスワンイベント」に直面したのです。それは、2月末に始まった米国とイランの戦争によるホルムズ海峡の封鎖から生じたもので、市場の構図は政策への懸念から供給とエネルギーの危機へと真に変化しました。 急騰する価格、世界中のメーカーによるパニック的な買い付け、そして高騰するエネルギーコストが、これまでにない衝撃を世界市場とタイの事業者に与えています。迅速に適応できる者は、ただ生き残るだけでなく、この危機から新たなチャンスを掴むことができるでしょう。
