Dirty Dozen: A methodology for tracking 12 types of common plastic found on beaches in Cape town

The Beach Cooperative (Co-op) began in 2015 when a group of volunteers started meeting every new moon to collect marine debris at our local surf break – the rocky shore at Surfers Corner in Muizenberg, Western Cape, Cape Town. The Dirty Dozen + Program offers a simple way to contribute useful data while also making a difference in terms of cleaning beaches. The Dirty Dozen are 12 types of litter selected to track different sources of marine litter. The protocol is led by a leader of the beach clean-up who must brief scribes on how to capture the data and the people involved in the clean-up must be aware of the 12 types of plastics. The collectors must call out and bag any of the 12 items as espoused in the methodology. The leadership provides general information about the beach i.e. the length of the beach (GPRs) as well as total items of the number collected. The totals are collated and the impact shared after the clean-up. The methodology also accommodates other items that are not the dozen list.
