Let’s look at the straw. It’s a great way of looking at this.
Have you ever really thought about the straw? You probably don’t use straws at home. You probably don’t use straws much - except when you buy a drink in a plastic, single-use cup. Why is that? Why do you suddenly want and NEED a straw, but not other times?
It’s because the cup. The cup has been chipped away and reduced in how much it weighs and how strong it is until it is nearly too flimsy to use without a lid. I mean, think about how hard it is to get the cup off the fountain to the counter until you slap that lid on it, then it becomes fairly durable. That’s because the cup doesn’t have much crush resistance until you put the lid on it.
The lid needs to be strong enough to support the top of the glass to keep it from collapsing. If it has a straw hole in the center of the cup, it can be thinner. It is cleverly designed with reinforcing ridges and to lock onto the cup so it supports it. But, if you don’t have a straw, you would need a sipping hole, which would make the lid weaker, so it would need to be thicker.
You probably never thought about this. You just know that using that cup without a straw is horribly hard, and it really sucks, and you’re always spilling it on yourself.
That’s because the cup, lid, and straw are a system. And in order to move away from using the straw, you have to change the entire system.
Yep, you can walk away from the counter at the gas station with your 52oz drink and your lid but no straw as an individual. But you can’t change the system that makes it really annoying to try to drink your drink without the straw.
Without changing the system which made the choice the default choice asking the end user to change their behavior away from the indicated use of the system is bound for failure. The only way to effectively drive end user behavior is to change the system to enable the end user to use the system more efficiently.
Never ban straws. Work with industry to figure out a more efficient drink package that uses less overall plastic. Work with industry to figure better ways of enabling single-use plastics to be replaced with multi-use plastics. Figure out ways of using single-use plastics multiple times. Build systems that don’t have single-use components.
Don’t discount ideas without a proper analysis. Perhaps the most effective solution is to make cups heavier duty again so they are multi use and don’t need a straw. Perhaps a solution where there is a deposit on cups and they are recovered and reused or reformed (I honestly don’t know which is more energy efficient) is the best way of handling it. Perhaps offering half-price refills (even in your competitor’s cups) is the way to go. Perhaps decoupling the purchase price of the cup and the drink that goes in it is the way to go. (Drink $1. Cup (a nice, reusable one) to put drink in is $5.) Perhaps paper is the right solution. Perhaps you could make an entire cup system out of paper that lasts for a day but biodegrades quickly is the answer.
The funny thing is that the plastic straws are actually almost as durable as the silicone or metal ones. I have a plastic straw that came with a drink from a gas station that I’ve been using for months. (Washed regularly, of course.) I’ve been using drink cups from gas stations for days or weeks at a time (again, washed regularly). The nicer plastic “Tupper Ware” style take out containers can be used several times. It’s actually amazing how many “one time use” plastics can be reused for a fairly long time with a modicum of care.
