Construction in progress contains incurred costs for the Biogas Project, Riverbank Project, and Zebrex equipment installation at the Keyes Plant.

Depreciation on the components of property, plant and equipment is calculated using the straight-line method to allocate their depreciable amounts over their estimated useful lives as follows:
| Years
Plant and buildings |  | 20 - 30
Machinery and equipment |  | 5 - 15
Furniture and fixtures |  | 3 - 5
The Company recorded depreciation expense of approximately $5.4 million, $4.9 million, and $4.4 million respectively, for the years ended December 31, 2021, 2020, and 2019.
