About Tenaris

 

Tenaris is a leading manufacturer of pipes and related services for the world’s energy industry and other industrial applications.

The manufacturing system encompasses steelmaking, tube rolling and forming, heat treating, threading, and finishing processes in 16 countries. Tenaris also has an R&D network focused on improving our product portfolio and our production processes. 

SCRAP is a company within the Tenaris group that is dedicated to the collection, storage, and processing of scrap (mainly domestic scrap). The plant, located in the city of Campana in the province of Buenos Aires, has a scrap shredder machine close to the Tenaris Siderca production site.

Approach to Sustainability

Tenaris uses advanced manufacturing technology combined with scrap recycling to minimize its environmental footprint and reduce carbon emissions in our operations. Tenaris is committed to reduce our environmental footprint to contribute to global and local goals. 

Desired Outcomes

The objective is to find a solution that allows the recovery of the material within the framework of a circular economy, avoiding waste disposal.

Considerations

The concept of using this as an alternative fuel for the cement industry and for internal use of the material as a replacement for coal in the Electric Arc Furnace has been tested. Results were uneconomic due to the equipment modifications required. A beneficial use not involving combustion would be preferred. 

The average fluff waste generated is approximately 12 kton/year.

Physical/chemical characteristics of the material for its co-processing:

  • High granulometric dispersion > 20 mm 10 % and < 20 mm 90%.
  • 20% humidity, 12% metals, 15-40% plastics, 6-10% wood, 2% textile among other materials as soil. 

Evaluation & Eligibility

Requirements of current regulations regarding the generation, treatment, and disposal of waste: 

  • Fluff is not considered special waste according to Argentinian regulation as it contains no hydrocarbons or polluting elements 
  • Legislation requires avoiding contamination and achieving highest possible degree of reuse

Clear Solutions

Solutions must clearly explain their separation, treatment, and reuse capacity.

TRL 6+

Solutions must be at a minimum Technology Readiness Level (TRL) of 6.

Model or Prototype

A model or prototype that represents a near desired configuration is required. Activities include testing in a simulated operational environment or laboratory.

Canadian

Must be a Canadian owned company or have primary operations in Canada.

Sustainable Development Goals

The SDG Connect program supports achievement of the UN Sustainable Development Goals. The SDGs addressed by this Challenge are:

SDG9

Industry, Innovation and infrastructure

SDG12

Responsible consumption and production

SDG13

Climate change

Foresight Canada is working with the Trade Commissioner Service of Canada in Argentina  to deliver this SDG Connect Challenge. Through this program, Canadian cleantech solutions and technology providers are connected with a key local company in Argentina, Tenaris, to help address a major sustainability challenge.
