However, we strongly believe that using disposable formworks has environmental benefits that go far beyond obtaining LEED points. We may not prove our hypothesis quantitatively, but we argue that we provide very serious benefits.
ENVIRONMENTAL BENEFITS OF LOGISTICS SAVINGS
One of our most important benefits comes from being 95% empty inside even though we are mostly used for filling purposes. Only 5% of a 100 cm high disposable formwork system, namely the two legs per m2 and the volume formed by the dome form is full. No matter what alternative material is used instead of disposable formworks, the volume to be filled must be brought directly to the construction site and transported horizontally and vertically within the field.
For example; let us assume that 20 cm of concrete will be poured on top of an 80 cm high crushed stone filling in an area of 1.000 m2 (finished section is 100 cm high). This is an operation of 47 trucks with a truck that can carry either a maximum of 21 tons or 25 m3. In contrast to that, 1 truck of disposable formwork is enough for the same volume!
The fuel spent by the trucks, the tear and wear of the vehicles, the intensity of the operation in the field, the horizontal and/or vertical transportation works of the filling material inside the structure... When all of these are taken into consideration, nobody can argue about the environmental benefits of disposable formworks that come in terms of both energy and carbon emissions.
