Conducting business in a sustainable manner means much more than just conserving resources. At McWane, sustainability is an integral part of our business and achieved by: safeguarding the health and safety of every team member; protecting the environment; making products using fewer resources; and constantly innovating to achieve these goals.

Sustainable Products

Sustainable Products

Ductile and grey iron castings are made primarily from recycled scrap iron and steel, and the final product is recyclable after its long, useful life. All ductile iron pipe manufacturers have a “buy-back” policy on ductile and grey iron pipes that have been removed from service. If you ship material to them, they will pay the going rate for scrap iron and steel. The manufacturing process includes environmentally sound practices.

Process water streams are recycled within the manufacturing process, and there are minimal water discharges. All waste waters are treated on-site before release. Spent foundry sand is recycled and used as a construction material. Contaminants are removed from gas streams so they do not vent to the atmosphere.

Iron pipe and fittings' performance is also environmentally responsible. The larger inside diameter of ductile iron pipe (compared to substitute materials) means that, for a given flow, it takes less energy to pump through ductile pipe. With its wall thickness and corrosion control, ductile iron pipe has a minimum anticipated service life of 100 years.

A men's regularity as a workman is to be attributed not only to the wages he receives but to the conditions under which he works... Reduction in the number of accidents represents economy, for nothing is more wasteful in industry than accidents.

J.R. McWane in 1921
