Increased number of reuses reduces the cost of materials for formwork material and labor costs for panel processing costs. Smooth finishes on concrete surfaces reduce cost and the low replacement ratio reduces the cost of carry-in and carry-out of transportation charges while the smaller amount of industrial waste reduces the cost of industrial waste.
In comparison with conventionally coated plywood, Katawaku-ecochan is slightly higher in price per sheet, however, it offers superior durability, and an increased number of reuses. As a result, the total cost is reduced and cost reduction is realized.

Comparison between coated plywood and Katawaku-ecochan
In comparison with coated plywood, its high durability allows material costs for formwork to be greatly reduced.
In comparison with coated plywood, less industrial waste allows the cost of industrial waste and transportation charges to be reduced.

Cost comparison table of generally coated plywood and Katawaku-ecochan (our estimation)
Finish cost for concrete surface is reduced.
Fine finish is realized without inclusion of plywood skin onto a concrete surface and adherence of coating film, and without slag on corners and on end butts.
| Conventionally coated plywood | Katawaku-ecochan |
 Outer wall of multifamily housing unit, 12 times of reuse |

Comparison of concrete surface between Katawaku-ecochan and coated plywood
Cost is reduced by less slag at separator holes, corners and end butt sections.
| Surface with conventionally coated plywood | Surface with Katawaku-ecochan |
 Inner wall of collective housing, 7 times of reuse |
 Inner wall of multifamily housing unit after 7 times of reuse |
 Outer wall of multifamily housing unit after 15 times of reuse |

Cost for scraping work is reduced.
Compared to coated plywood, since adhered concrete is easier to remove by the form release agent, scraping work is easy, and the cost can be reduced. In addition, a nylon brush and mop can also be used.
