The Environmental Impact of Compostable Take-Out Containers | Eater
"A Portland coffee company that launched a zero-waste shop in 2018 and instituted a 25-cent charge for disposable to-go cups paired with a 25-cent discount for customers who bring their own; the policy reportedly cut disposable cup use from 66% to 31% and generated a 17% BYO rate, leading the business to apply the surcharge across all three of its Portland cafés." - Gosia Wozniacka
