Plastics represent more than 80% of marine waste, and despite being new materials, their persistence in nature can lead to great risks for humans and wildlife.
It should be noted that 10% of the total plastic waste we generate ends up in the oceans. And today plastics have been found in almost every aquatic habitat on the planet.
Once plastics enter the ocean circulation, they tend to accumulate in the regions of oceanic gyres and convergence zones.
The origin of the environmental problem could be imagined as a circular economy.
There are different ways to classify plastics, but the most common and everyday way is with plastic recycling symbols.
The container numbers correspond to the Resin Identification Code, created by the SPI (Society of the Plastics Industry) to identify the resin content of each container in order to facilitate separation prior to recycling.
