If we want to stop litter, one of the most powerful tools to do this it to first identify what types of items are being littered. Then once identified, have some action taken on those products to stop their littering. Litterstopper is a simple app that will allow you to record the litter in your location and email it to any address you nominate. It is also simultaneously stored on the litterstopper.com database. Litterstopper will allow you to audit up to 24 types of commonly found plastic litter or rubbish items. Or you can perform a smaller audit number if you are only seeking a few target items in your cleans. The app also records other parameters, such as the number of manhours spent on the clean, the time, how many kgs of rubbish were collected, what volume of rubbish was removed, what length of beach or street was cleaned. These parameters allow you to compare one site against another site.
