A university with 3000 students is suitable for collecting waste products. Garbage in a school with 3,000 people must be easy to collect. Because first of all, a school with 3,000 students has a lot of waste products such as plastic bottles, which students don't need, and waste recycling can also help students develop good habits of environmental protection and thrift. In addition, there are a lot of waste paper and books in the school with 3000 students, which cannot be wasted and can be recycled. So a university with 3000 students is suitable for collecting waste products.
