Study Notes
Recycling Plastic
- Recycling plastic involves collecting, processing, and transforming used plastic into new products.
- The process includes sorting plastic types, cleaning residues, shredding, melting, and reforming into pellets.
- This transformation is both chemical, involving structural changes at a molecular level, and physical, through the use of heat and pressure.
- Recycling plastic benefits society and the environment by reducing landfill waste, conserving land, decreasing pollution, and conserving resources.
- It also reduces greenhouse gas emissions and promotes a circular economy by reusing materials instead of discarding them.
- Recycling supports job opportunities in recycling industries.
- Challenges include difficult sorting, potential pollution from machinery, and the potential for lower quality recycled plastic.
- Suggested improvements include developing more efficient sorting technology using AI and sensors, and encouraging companies to incorporate higher percentages of recycled plastic in their products.
