Consumption of materials

Ansaldo STS is aware of the contribution that each company can give to safeguarding the world’s resources by adopting policies to reduce the intensive use of raw materials, an objective promulgated by the OECD Council and in the sustainability strategies of many nations.

To explore the issue of raw material consumption, in 2013, Ansaldo STS began analysing its supplies, and, specifically, “Direct materials”, which it divided into two different types: “Racks and Cabinets” and “Cables”. These make up 4% and 3% of Ansaldo STS’ expenditure, respectively. The company acquires finished products in these categories from third party suppliers only. Accordingly, to calculate the quantity of raw materials contained in the products, they must be broken down and subject to rather complicated estimates. For example, to estimate the amount of copper in the total cables purchased, first, all optical fibre and aluminium cables must be excluded. Next, low voltage cables must be separated from medium and high voltage cables (as the latter have many more non-copper parts). Other variables to consider are sections – just to give one example of many of these instances, two medium voltage cables, for 35 sqmm and 240 sqmm sections, respectively, present significantly different quantities of copper, but nearly equal non-copper parts – and the type of screening and reinforcement.

Beyond issues arising from estimates, Ansaldo STS is pushing for standardised design, which will reduce the use of these types of parts.
