Question

What is the difference between internal and external recycling? Give examples of each.

Answer 1

Sr. No.	Internal Recycling	External Recycling
1.	Waste and scrap generated during the manufacturing process.	Materials collected from consumers that are worn out or obsolete.
2.	Contained within the manufacturing facility, with no public involvement.	Involves public participation through curbside collection, drop-off centers, or buy-back centers.
3.	The material properties typically remain the same, so it’s a closed-loop system.	The material is often “downcycled” into a product of lower quality or value.
4.	Manufacturers have complete control over the waste stream, which is more consistent and pure.	The waste stream is more diverse, with varying levels of contamination.
5.	Examples: Metal manufacturing, Rubber, plants, Plastic manufacturing	Examples: Paper, Aluminum, Plastic bottles
