The idea was to create a “plastic target”, in order to investigate if plastic floating in the sea can be detected, depending on its Spectral Signature using satellite or drone. Firstly, we took in situ and laboratory measurements on plastic to create a representative database and discovered its special characteristics which were used as guidelines to spot it. After creating and taking measurements on the target we analyzed the data and created a Prototype Code. Finally, by testing the Prototype Code of plastic bottle, we confirmed that accumulated plastic rubbish can be successfully detected using satellite or drone. Thus, a new, effective way of tracking plastic rubbish is introduced which can contribute in the protection of the marine environment.
