Square Watermelons? Has Sustainability Gone Too Far?

June 29, 2009

When I first heard of this new idea coming to us from Japan, I was certain sustainability advocates were dancing and rejoicing in the streets. After all this idea borders on genius! Japanese farmers discovered they could grow watermelons in square glass cases and the end result was a perfectly square watermelon. 

There are probably few items we buy that are as inefficient as watermelons when it comes to storage and shipping.  Consider all the wasted space in your refrigerator and the truck that was used to bring them to your local grocery store. I know green minded advocates are already calculating and salivating at the equivalent fleets of cars that this will “remove from the highway."

Green Packaging Can Learn Much from This Idea
It is difficult to believe farmers came up with this innovation because it would make most packaging engineers jealous. It focuses on several key points we as packaging designers and suppliers consider, or should consider every day:

• Maximum use of cubic inches – as we talk more and more about CO2 levels and carbon footprints, every square inch has a cost to the bottom line and the environment. 

• Making use of the product’s natural ability to structurally support itself.  Rather than two watermelons resting on each other at a single point, this new design allows for total support, (dare I say it, with NO protective packaging or cushioning material) especially on the corners where it is most needed. 

• This design will enable higher stacking, maximum cubes while minimizing damage and product loss. Because weight and pressure are so easily and effectively distributed, bruising may be completely eliminated. 

• Innovation breeds innovation. I am certain scientists in laboratories are feverishly working on square tomatoes, potatoes and especially square pumpkins. I am not sure the market will accept square jack o’ lanterns but I admit the possibilities are enormous and endless. 


The Traditionalist’s Perspective
Then I started thinking about how things are meant to be. If the Good Lord wanted square watermelons, why didn’t He make them square? Being omniscient, He certainly must have known how badly we would screw up the environment and how important sustainability would eventually become. 

Is it the right, long term thing to do? I admit many if not most of the world’s innovations in the last few decades have come from Japan. However aren’t they the same people who gave us bonsai trees? Sure they’re interesting shapes but don’t deliver a whole lot of shade, do they?  

The 4th of July Can Be a 
Sentimental Holiday Too

I suppose after the years pile on, every holiday becomes day of reflection mixed with gratitude. When I think of “The Fourth”, I think about freedom and about the men and women who are serving domestically and overseas to help preserve the rights we usually take for granted. I also gratefully consider all the people who have sacrificed their lives so we can maintain our independence and enjoy a carefree, summertime, three day weekend. 

I think about burgers, hot dogs, cold beer and a refreshing ice cold watermelon, especially when a child is enjoying it with reckless abandon. I think I have come to the conclusion square watermelons may be an excellent sustainable idea but I kind of like the way the curved ones match those young summer time smiles.  

Have a happy and safe Fourth of July holiday.

Gosh Alex. That sounds like a cruise ship cabin without the pleasure of a great dinner. :) Thanks for the follow up comment. Dennis

Thanks Dennis! My brother lived in Kyoto, and when I visited I was impressed by the scale of everything, small sink, small shower, small fridge, small room... Japan is after all an island. (Mebbe the idea can transfer well to Manhattan?)

One Fourth of July, while working in the produce department of a grocery store, a couple other guys and I had to unload a whole semi trailer of watermelons from Texas by tossing them like a bucket brigade. Even then, I dreamed of square watermelons that could be unloaded with a conveyor. Now it's possible!

A. Silverman, that is a very interesting perspective. We ship a lot of freight and the two biggest cost factors are space and weight. Trucking companies hate hauling bulky, light weight product such as foam packing peanuts and they love hauling heavy products like pallets of hardware because in most cases, their rate is based on total weight. So if you could stack watermelons higher because they are square, you should be able to haul more weight in the same floor space. Theoretically this would result in cost savings for the shipper and less CO2 for the earth. All of that aside, I think Alex Webb had the best observation above when he said square watermelons were more than likely designed to fit small Japanese refrigerators in small Japanese apartments. I sincerely appreciate your comments as well as your sense of humor. Have a great weekend. Dennis

Very likely not green at all, for 2 reasons. 1)Utterly useless unless the grocer wants to stack them on his shelf -- in which case I can assure you everyone will want the one on the bottom, wouldn't you? But I digress: I happen to have a watermelon, old-fashioned type. It weighs 14.2 lbs and is roughly an ellipsoid 9" x10". 3170 of my watermelons will "weigh out" a truck, 45000lbs, long before the trailer space is filled. In fact, my watemelons even if absolutely perfectly "square", would fill only ~50% of a 48' trailer when it "weighs out". So, no green benefit from freight savings whatsoever. Watermelon is, after all, essentially H2O, 62.3 lbs/cubic foot. 2) If the boxes are truly glass as in "smash to smithereens" glass, Gaaah! Glass shards in my square watermelon -- call my lawyer!!! But if they are clear plastic they are likely polycarbonate. Gaaah! Polycarbonate boxes!!!! Omigod, death boxes! As in "bisphenol A polycarbonate" -- BPA. Good thing you don't eat the rind! And how much GHG does it take to make and transport these boxes? Energy to feed the workers who set them up and then remove the encased, squared melons? Not so green.

This is only my second post at PD but I think I am going to enjoy it. I sincerely appreciate the responses and interaction as well as the really good input and suggestions. Thank you!

One more plus of a square watermelon is it might be easier and/or safer to cut into with a steady square bottom. Enjoy your watermelons this holiday!

There are certain types of produce that lend themselves to this technique. Members of the melon and squash family are obvious. It is hard to imaging however that it would be cost effective to grow and harvest produce in this manor for general consumption. It might be possible to achieve a positive cost benefit relationship if the grower controlled two, three or four of the sides rather than all six.

Dennis - well said! I love your articles and your picture of a happy happy little girl eating her watermelon.. I bet she doesn't care what shape it is:) All the best ... hello to the family!

Hi Dennis, Interesting thoughts on distribution effects. As much as it may help shipping, square watermelons were designed for just for the end users you mentioned, small refrigerators in small Japanese houses. The hinged and latched lexan boxes that they grow in are available on-line. It differs from growing a peach in a glass bottle in that the box must open after the melon has reached maturity. I imagine they taste the same, but I wonder if the box prevents ventilation or could be susceptible to mold where there is full contact with the box.

So, you don't have to be a cartoon character (Homer Simpson) to buy a square watermelon in Toyko? I wonder if these watermelons, like Homer's $150 fruit, fetch a premium price in addition to reducing carbon footprint.

Hi Marybeth and thanks for the response. I agree we as green consumers are willing to sacrifice a lot in the name of sustainability but taste is typically not one of them. Enjoy your holiday!

Well I guess the proof of the square watermelon will be in the TASTE. If they can guarantee it tastes good AND is more efficiently shaped, they may have something. Like packaging, it has to do its job (protecting shipped items in packaging or providing flavor and nourishment in melons) first... anything else is "gravy". Like that niche product of yours Dennis that protects heavy fragile items so well, the NEST that offers standalone protection.
