**BPA Free means the product doesn’t contain BPA, making it safe for consumers eating food from these containers. You can be confident that BPA Free containers are safe for food and drinks, and no harmful substances will leach into the food, even when heated.

Natural resources are dwindling every day. How can a Circular Economy solve this problem when humans still need these resources to survive?

Before becoming the aluminium cans we’re familiar with. There are production processes they must go through. Ever wondered how the aluminium cans holding your drinks are made? What’s the production process they go through? Let’s dive into it together in this article.

The TreeCycle of Joy, a sustainable Christmas tree made from over 10,000 recycled aluminium cans, was once displayed in front of Siam Discovery.

Abstract: Inconel 718 is a superalloy, considered one of the least machinable materials. Tools must withstand a high level of temperatures and pressures in a very localized area, the abrasiveness of the hard carbides contained in the Inconel 718 microstructure and the adhesion tendency during its machining. Mechanical properties along with the low thermal conductivity become an important issue for the tool wear. The finishing operations for Inconel 718 are usually performed after solution heat treatment and age hardening of the material to give the superalloy a higher level of hardness. Carbide tools, cutting fluid (at normal or high pressures) and low cutting speed are the main recommendations for finish turning of Inconel 718. However, dry machining is preferable to the use of cutting fluids, because of its lower environmental impact and cost. Previous research has concluded that the elimination of cutting fluid in these processes is feasible when using hard carbide tools. Recent development of new PCBN (Polycrystalline Cubic Boron Nitride) grades for cutting tools with higher tenacity has allowed the application of these tool grades in the finishing operations of Inconel 718. This work studies the performance of commercial PCBN tools from four different tool manufacturers as well as an additional grade with equivalent performance during finish turning of Inconel 718 under dry conditions. Wear tests were carried out with different cutting conditions, determining the evolution of machining forces, surface roughness and tool wear. It is concluded that it is not industrially viable the high-speed finishing of Inconel 718 in a dry environment. Keywords: dry turning; Inconel 718; PCBN; wear

Making each new aluminium can is not an easy task. However, aluminium can manufacturers are highly aware of consumer safety and experience, giving significant importance to every step of the production process.

“Eternal Bloom” upcycled aluminium cans waterfall was displayed in front of Central Embassy shopping center to celebrate the 75th anniversary of Central Department Store.

*Bisphenol A (BPA) is a chemical added to various products and food containers, like plastic milk bottles, where it helps make the plastic stronger and more flexible. BPA is also used as a lining inside canned food containers to prevent erosion and corrosion. However, BPA can leach into the body from food that’s been in contact with containers using this substance, causing various health issues, whether through inhalation (headaches, nausea), skin contact (redness, itching), or ingestion (nausea, vomiting), leading to various diseases such as cancer, diabetes, heart disease, etc.

Starting from the raw material preparation like Aluminium Coil, which is over 69% recycled aluminium melted, cast into logs, and then rolled into sheets, these aluminium rolls then undergo several steps before being sent to the can manufacturing plants.

Feature papers represent the most advanced research with significant potential for high impact in the field. A Feature Paper should be a substantial original Article that involves several techniques or approaches, provides an outlook for future research directions and describes possible research applications.

Aluminium cans and their ends are sent separately to the beverage filling plants and are assembled after the beverage is filled using a Can Seamer machine in an overlapped manner, ensuring a tight seal between the can body and the end.

Despite the numerous steps involved in the production of aluminium cans, the result helps significantly reduce the use of natural resources through 100% recyclable used aluminium cans, leading to new cans ready for use in an endless cycle, known as “Closed Loop Recycling.”
