> Why do small if you can go big right away?

You're missing the fact that this sort of infrastructure requires a robust business case. That's why scale is critical.

Recycling bottles and cans has a solid business case. Glass and aluminium are straight forward to recycle at an industrial scale, but would be pointless if they were kept at an artisanal scale.

Any moralistic argument is pointless if you can't put together a coherent business plan. The people you need to work and the energy you need to spend to gather and process whatever you want to process needs to come from somewhere. How many vape pens do you need to recycle per month to support employing a single person? Guilt trips from random people online don't pay that person's rent, do they?

> Everybody makes fun of paper straws.

This is specious reasoning. The core issue are tradeoffs, and what you have to tolerate or abdicate. Paper straws are a red herring because the main criticism was that, at the start, they failed to work as straws. So you were left with an industrial demand to produce a product that failed to work and was still disposable.

If you look at food packaging and containers, you are faced with more thought-provoking tradeoffs. Paper containers don't help preserve food as well as plastic ones. Packaging deteriorates if exposed to any form of moisture, and contaminates food so quickly tk the point you can taste cardboard if you leave them overnight. This leads to shorter shelf life and more food waste. Is food waste not an ecological problem? How do you manage those tradeoffs?
