The start of a journey
Despite these two compromises, the LAGO effort was an important step towards the achievement of a product designed in a more mindful way, integrating environmental parameters into its realization. We are aware that the road ahead is still very long, but with Divano AIR we have taken the first step.
What is LCA? With Divano AIR, we have, for the first time, taken a scientific approach to eco-sustainable
design. In order to achieve this we have made use of LCA (Life Cycle Assessment) methodology, a tool that permits the quantitative assessment of the environmental impact of a product or service over the full duration of its life cycle, from the choice of raw materials to its disposal.
The LCA methodology utilized makes reference to the international standards defined in ISO14040-44.
Thanks to software specifically designed for the analysis (SimaPro 7.2 – Database Ecoinvent 2.2 – 2010) we calculated the environmental impact of the materials (metal alloys, aluminium alloys, polymers and polyurethane filling) and of the upholstery (organic cotton and Ecological cotton, eco-leather in high solids polyurethane).
Our objective is to repeat the LCA study annually in order to evaluate improvements, involving our suppliers in the development and measurement of the real environmental performance of the materials and semifinished products.
To learn more about this:
We found ourselves faced with an important decision with respect to the frame structure, which turns out to be the part of the product with the greatest impact. We had two alternatives: To use two small fastening straps for the back rest in aluminium or a single, larger strap (with a greater environmental impact). We preferred the single plate which makes it easier for the customer
to use. The double plate, although more ecologically sustainable, would make it more difficult to assemble and disassemble the back rest and the frame.
Unfortunately it was not possible to select the most eco-sustainable option for
all of the upholstery. For example, for the natural leather upholstery, products
made using tanning techniques with a very low environmental impact were
evaluated, but could not be chosen due to the fact that it would have been
necessary to charge an extremely high, and therefore less democratic, price.
This problem was not presented by the organic and Ecological cotton fabrics,
which permit the maintenance of a range of prices accessible to everyone.
