Which of the following is a common waste abbreviation for cardboard?

Cardboard is commonly abbreviated as OCC, which stands for "Old Corrugated Cardboard." This abbreviation is widely used in recycling and waste management contexts to distinguish this material from other types of paper or cardboard. OCC specifically refers to cardboard that has been used and is intended for recycling, which is an important category in waste management as it helps in identifying recyclables and processing them appropriately.

The other abbreviations do not represent cardboard; for example, MP might refer to mixed plastics or other materials, while T could stand for trash or another waste category. C alone lacks specificity, making it less useful in the context of waste management terminology. Understanding these abbreviations helps waste advisors communicate effectively about recycling materials and managing waste streams.
