Plastics in the marine environment: Could the seawater indicate a path for waste management?

Sustainable Chemistry for the Environment, 2023
Despite the versatility of polymeric materials (plastic), they generate significant impacts on the environment. The actual plastic recycling system presents some unsolved issues since, worldwide, only a portion of this material is collected for recycling.

The impact of secondary materials’ quality on assessing plastic recycling technologies [PDF]

E3S Web of Conferences, 2022
Global plastic production reached a new high in 2019. The high use of plastic leads to a high amount of plastic waste. Thereof, only 33% was collected for recycling in Europe.
