We design products for multiple repetitions, so we save the cost re-manufacturing of entire formwork. Instead of pushing for new material & re-manufacturing of formwork, we intent to re-design & use the existing material. At our place till today we have successfully re-used more than 70% of material as it is, and 20% is modified. Adding up, in short 90% of the existing material is re-used, only 10% had to be bought new that also in few cases.
