Study on mechanical characteristics of mixed heterogeneous coastal plastic waste

Coastal plastic pollution is a common problem in many coastal regions in Malaysia. Arising from environmental concern and at the same time supporting waste to wealth program, the best way to overcome coastal plastic pollution is by recycling. However, due to photo degradation and nature of the surro...
