How to make disposable aluminum bottles from scratch

The following article is a guest post by Ankit Gupta, a Senior Consultant and Research Associate at B.H. Khan & Co. in Mumbai.
Recently, a team of researchers from the Indian Institute of Technology, Mumbai (IIT-M), along with a few other institutes, have been working on developing a prototype of a reusable disposable aluminum bottle.
The new design would reduce the amount of disposable aluminum waste, as well as reduce the need to import aluminum bottles as plastic ones do.
It could also cut down on the time it takes to manufacture the bottle, according to the researchers.
While a reusable aluminum bottle is a good idea, it doesn’t have a huge market share.
As of March 2017, the disposable aluminum plastic bottles market was worth Rs. 4.6 lakh crore (US$11.7 billion), and the market share of disposable glass bottles was barely 50%.
According to an IIT-B, a recent survey on consumer preferences revealed that only a fifth of the people would buy a disposable plastic bottle, and only a quarter of the consumers would buy an aluminum bottle, which would be the lowest percentage of disposable plastic bottles.
It would be a relief if the disposable plastic container market could sustain itself by only using aluminum bottles, which have a much higher price tag.
“The disposable aluminum container market has been going for two decades, and we are hoping to revive it by creating a reusable reusable aluminum container,” said Ankit.
For the disposable metal bottle, the team has been working hard to optimize the properties of plastic to improve its performance.

The second way is a metal that is hollow and is attached to the bottle by a plastic strap.
“A plastic material that is very light is very attractive to use, and the lightweight and flexible nature of plastic makes it ideal for making a disposable aluminum disposable bottle,” Ankit told Quartz.
Accordingly, the researchers had developed a prototype that would have a plastic that was lightweight and strong enough to be a suitable plastic for the aluminum disposable.
This aluminum plastic has been cut with two saw blades, and then coated with a layer of a polyethylene resin.
The polyethylenes also act as a stabilizer, so that the aluminum will stay in place even after being broken and scraped.
In addition, the polyethyles also absorb the energy of the blow and create a vacuum, which helps the aluminum stick to the glass.
The polyethylenes also act to prevent the metal from escaping and forming a film on the surface.
After testing the prototype, the scientists were satisfied that the new aluminum disposable was better than its plastic counterparts.
“Our prototype is much more flexible than its aluminum counterparts.
We have also developed an air-tight seal on the bottom, which prevents air from escaping from the aluminum bottle,” said Manjesh Kumar, the lead researcher.
“The aluminum plastic also absorbs the heat of the flame of the burner and is thus much more durable than its polyethylate counterparts.”
In a future study, the new design is expected to be able to withstand a 1,000-kcal (2,300-degree Celsius) flame, so it could also be used in small appliances, such as microwaves.
This new design could also allow people to save money on disposable plastic bags.
According to Kumar, disposable plastic bag manufacturers are now targeting consumers with an “e-commerce model” to get more people to buy their disposable bags.
“We have identified a niche where consumers like consumers and don’t like the extra cost of plastic bags, so they are interested in a disposable reusable plastic bag.
As a result, manufacturers have started introducing this product as an option to consumers,” said Kumar.
