A1 Raw material supply | Upstream Process

Module A1 (Raw material supply) includes the extraction and processing of all raw materials and energy carriers necessary for the production of the final product, as well as the upstream processes needed for the production and processing of all other inputs (ex. packaging).


  • Forestry (Florestal Eucalyptus forest) with biogenic CO2 and CH4 emissions from charcoal carbonization (Brazil), with emissions of CO2 compensated by forest sequestration;
  • Biofuels combustion of biogenic charcoal in pelletization plant and blast furnace (Jeceaba, Brazil) with emissions of CO2 compensated by forest sequestration;
  • Purchased steel bars/ingots and tubes;
  • Extraction and Processing of raw materials, specifically for Iron & Steel production, such as steel scrap, pig iron, coke, coal, lime, limestone, ferroalloys, all supplied for Youngstown (USA) and Jeceaba (Brazil) integrated sites with steel mills;
  • Steel manufacturing processes: Eucalyptus forest, charcoal production and iron mine both in Brazil, pelletization plant in Brazil, steel mills.

A2  Transport from mill to mill | Core Process

The transport of all raw materials from the provider to the production site is included.


  • Transportation of purchased steel to rolling mills (in Europe and China);
  • Transportation of raw materials to Youngstown (USA) and Jeceaba (Brazil) integrated sites with steel mills;
  • Relevant means of transport:rail, truck, barge, sea freight.

A3 Manufacturing | Core Process

The manufacturing process, including energy and water consumption, direct emissions and waste treatment arising from this stage, is taken into account in module A3 (Manufacturing).


  • Tubes manufacturing processes: rolling mills,heat treatment and finishing plants worldwide;
  • Production and consumption of natural gas for energy production;
  • Production and consumption of fuels (gasoline, diesel, propane) for internal transportation;
  • Generation, transportation and consumption of electricity purchased from public and private providers;
  • Transportation of steel bars and of semi-finished tubular products between Vallourec facilities;
  • Water intake for the manufacturing processes (mainly for cooling of machines and of products) and discharge of wastewater;
  • Treatment process of waste generated by the manufacturing processes.

A4 Transport to final destination | Downstream Process

It includes the transport of final products to the clients in module A4 (Transport).


  • Transport of tubular products to final customer destination;
  • 4 regions from which Vallourec operates were considered: North America, South America, Europe/Africa and, Middle East/Asia;
  • Means of transport can combine rail, trucks, barges and sea vessels.
