The concern for the potential global change consequences of increasing atmospheric carbon dioxide has necessitated the development of mechanisms to reduce or stabilize atmospheric carbon dioxide.

During the next several decades, a program focused on terrestrial sequestration processes could make a significant contribution to abating the increase and easing the transition to other renewable energy sources.

This project examines the potential use of lands, which have been disturbed by mining, highway construction, or poor management practices, for terrestrial carbon sequestration.

The approach includes examination of the effects of amendments with solid byproducts from fossil-fuel combustion, paper production, and biological waste-treatment facilities for enhancing carbon sequestration.

Triple benefits from this approach
  • carbon storage

  • byproduct utilization

  • land reclamation.
