SUMMARY

Melting plastics from ocean garbage patches, such as the Great Pacific or Atlantic garbage patches, results in a non-homogeneous mass rather than a single solid mold. The process involves using a furnace with an inert gas capable of reaching high temperatures to melt various plastics. However, due to the differing chemical compositions of the plastics, they do not combine effectively, leading to a messy outcome that is not suitable for recycling. As noted by participant SteamKing, the resulting material would lack uniformity and usability.

PREREQUISITES
  • Understanding of plastic types and their chemical properties
  • Knowledge of thermal processing techniques for plastics
  • Familiarity with recycling challenges associated with mixed plastics
  • Basic principles of waste management and environmental impact
NEXT STEPS
  • Research the properties of different plastic types, such as PET, HDPE, and PVC
  • Learn about thermal depolymerization processes for plastic waste
  • Investigate recycling technologies for mixed plastic waste
  • Explore environmental impacts of ocean plastic pollution and remediation strategies
USEFUL FOR

Environmental scientists, waste management professionals, and anyone interested in the implications of ocean plastic pollution and recycling technologies.

What would happen if I trawled one of the oceans garbage patches (say the great pacific or atlantic garbage patches) and put everything I trawled into a furnace with an inert gas hot enough to melt the majority of plastics I picked up, what would be the outcome?

I am looking to know more about why certain types of plastics may not combine with others into a big mold.

You would be making a big mess which you wouldn't be able to recycle.
 
Would the plastics still form 1 solid?
 
Hard to say. Most likely yes, but not a homogeneous one. As SteamKing wrote, all you will get would be something messy.
