The number of trees saved by recycling one ton (or 2000 pounds) of paper can vary based on several factors, including the type of paper recycled (e.g., newsprint, office paper), the pulp yield from recycled paper, and the size and age of the trees used for paper production. However, here are some general estimates:

1. Office Paper: Recycling one ton (2000 pounds) of office paper can save approximately 17 trees. This estimate considers the average pulp yield from recycled office paper and the size of trees typically used for paper production.

2. Newsprint: Recycling one ton of newsprint can save around 12 to 13 trees. Newsprint paper tends to have a lower pulp yield compared to office paper, which affects the number of trees saved per ton.

3. Mixed Paper: If considering a mix of various types of paper (including cardboard and other paper products), the number of trees saved can vary, but it generally falls within the range estimated for office paper and newsprint.

These estimates are based on typical calculations used by environmental organizations and paper recycling initiatives. It's important to note that the specific number of trees saved can vary depending on recycling efficiency, pulp yield, and other factors related to the paper recycling process. Nonetheless, recycling paper remains an effective way to conserve trees and reduce the environmental impact of paper production.
