Example of annual costs, savings and accumulated savings
From an actual Biotrans customer's case study - prepared by UNISA Graduates for a MBA thesis

NOTE: the cost of a preserved pole with a Field Liner fitted is calculated by the model used here, and under normal service conditions in most countries, this cost is typically the case cost of the pole plus 33% for the cost of the Field Liner. This is a generic model. Please contact your nearest representative for any assistance that you may need.
