When reusable is worth it (and when it is not)
Quick answer
Worth it almost always: insulated bottle, coffee cup you actually carry, safety razor, menstrual cup, silicone bags, safety-razor blades, produce bags, recycled toilet paper.
Worth it if you use it enough: cotton tote (130+ uses), reusable coffee pod (50+ shots), reusable K-Cup (30+ brews), stainless straw (50+ uses).
Rarely worth it: biodegradable disposable cutlery, "compostable" plastic bags that need industrial composting, one-off single-brand refill schemes that ship more packaging than they replace.
The three questions
- Will I use this weekly for a year? If no, do not buy it.
- Does it replace something I buy every week? If yes, the breakeven arrives fast.
- What happens to it when it dies? If the answer is landfill, the sustainability score should reflect that.
The unglamorous truth
The biggest reusable wins are boring: the flask you refill instead of buying bottled water, the razor blades that cost 15c, the toilet paper delivered in cardboard. Buy those first. Everything else is optimisation.

Frequently asked
- Are compostable plastics genuinely compostable?
- Usually only in industrial composting facilities at 55°C+. In a home compost or kerbside bin they behave much like conventional plastic.
- Is bottled water ever OK?
- When tap water is unsafe, yes. In every other case, an insulated bottle is a lower-impact answer within a week of daily use.
- How do I know a brand is genuinely sustainable?
- Look for third-party certifications (B Corp, 1% for the Planet, Climate Neutral), material transparency, and a working repair/refill program.
