Return-and-reuse glass bottles.Our milkshakes are delivered in returnable glass bottles, which we collect, wash and reuse again and again. Simply give your bottles a quick rinse and leave them on your doorstep the evening before your next delivery. Even the foil lids can be recycled. Collect all your lids as you go and scrunch them into a ball until it's the size of a tennis ball, then pop it in your recycling bin. It takes a bit of patience, but we reckon it's worth it.
