IS IT GREEN?: The Biodegradable Soft Drink Can

The cans themselves don’t present a problem, as aluminium can be recycled infinitely without a loss in quality. About half of the cans  consumed in the US are recycled. The problem is the other half – the vast amount of cans that end up in rivers, on sidewalks and in fields. People’s ignorance when it comes to recycling negatively impacts the world environment and human health, resulting in wasted energy and pollution generated from mining and other processes used to produce new aluminium. Single-use containers are admittedly convenient, but the environmental effects are disastrous. Every can thrown in the bin must be replaced with a new can made from virgin materials, which most people neglect to reflect on after lunch or on the bus.
Taiwanese design collective Haoshi  has taken it as their mission to solve this sad equation. Working in collaboration with PLA Studio, the team recently released a limited edition of containers. They hope that their concept will replace single-use containers in the future. The can, ironically called Tin Can (even though it’s not metallic) is made of Poly-Lactic Acid (PLA) – a starch material extracted from corn. PLA has the same properties as petroleum plastic, but without the negative effects – it is biodegradable and becomes soil  after 180 days in a compost system.
The Tin Cans have double-layered walls, making them resistant to high heat and able to keep cold beverages chilled for long periods of time. They have a well-sealed lid which lets one open and close the container as many times as one wishes. The top comes off to refill the can.
For those of you that are eager to try Haoshi’s cans out, they are for sale online here . There are competing versions out there as well: One Less Product  make one and another is called Eco Can .
The various eco-friendly cans are surely easy on the eye, but as a whole the concepts have holes, with the obvious question being “why you should recycle, or indeed discard, a cup that is reusable?” To be able to fill the can you also have to purchase your beverage of choice in some container that very well may be made of PET  or aluminium. More products doesn’t solve our problems – making objects from biodegradable materials is a step in the right direction, but those products need to be connected to systems that help people change their behaviour. Without systems that close the loop, the can isn’t much more than a fancy thermos.
It’s unclear how much the Tin Cans and it’s competing versions cost to produce, compared to the ones in aluminium, which makes it hard to evaluate the usability of them and how realistic the idea actually is. Perhaps one shouldn’t be too critical of projects on developing level, which these clearly are, but one can’t help to believe that once designers truly take responsibility and design for a closed loop we can take their ideas seriously.
