Ophaalkalender solves a simple problem: getting your local waste collection schedule into your calendar automatically.

Instead of manually checking mijnafvalwijzer.nl, you can subscribe to an iCalendar feed that automatically updates with your collection dates.

How It Works

  1. Enter your postal code and house number
  2. Get a subscribable iCalendar URL
  3. Add it to any calendar app (Google Calendar, Apple Calendar, Outlook)
  4. Receive automatic updates
