2) Comparisons: stainless steel VS aluminum, steel, polyethylene

FIRE:

Polyethylene melts at a temperature of 126°-130°C, and its breaking point is only 260°C, not to mention the toxic substances released in the fumes.

At 200°C, aluminum retains only 20% of its initial resistance capacity (at 20°C), while stainless steel still retains more than 70% of its capacity at 20°C. At 550°C, aluminum is completely melted, while stainless steel still retains more than 60% of its 20°C capacity.

​

CORROSION:

Aluminum corrodes on contact with water and is unsuitable for marine environments. Chlorides, sulfides, and galvanic reactions destroy aluminum very quickly.

Steel undergoes rapid corrosion when in contact with water; even a simple impact on the surface paint triggers this phenomenon. Furthermore, corrosive substances accidentally spilled by the public damage steel, even in the case of double-walled tanks, which deteriorate one wall after the other. Too many soil pollution accidents must be avoided.

With a chromium content of at least 10.5%, stainless steel benefits from permanent protection against corrosion thanks to a self-regenerating passivation layer. Stainless steel is the most corrosion-resistant material.

​

MECHANICAL STRENGTH:

HDPE has low abrasion resistance, low rigidity, and low mechanical strength.

In terms of mechanical properties, aluminum is known for being lightweight and malleable, making it easily formable and useful for applications where lightness is important, with low mechanical strength. Many tanks leak, causing soil pollution.

Stainless steel is harder and more resistant, making it useful for applications where mechanical strength is important, such as wear parts, pressure vessels, or fasteners.

 

​

UV AND TEMPERATURE DIFFERENCES:

Polyethylene does not withstand UV radiation for long. It oxidizes under significant temperature changes, and the material degrades in air and water, creating a public health problem. The warranty period offered by manufacturers is very short (1 to 2 years).

Stainless steel is resistant to UV radiation, frost, and significant temperature variations.

 

RISK OF STAINLESS STEEL AND ALUMINUM

COMBINATIONS:

​Two materials like stainless steel and aluminum, which are considered quite corrosion-resistant individually, should not be combined due to the risk of galvanic corrosion. Galvanic corrosion occurs when stainless steel and aluminum are in direct contact, particularly in the presence of an electrolyte such as water or moisture. In this galvanic reaction, aluminum acts as the anode and corrodes preferentially, while stainless steel acts as the cathode and remains protected.

RECYCLING, CIRCULAR ECONOMY, ECOLOGY:

PLASTIC, EPD, HDPE: “Although two recycling techniques exist – mechanical and chemical – 91% of plastics still end up in landfills or are incinerated (source: Statista, 2023).”; “The environment in which plastic is found also influences its rate of degradation. Exposure to the sun’s UV rays accelerates the fragmentation of plastic, a process called photodegradation” (source: Ecology Without Borders).

Steel, for outdoor use, must undergo polluting surface treatments. Anti-corrosion coatings on steel objects exposed to the elements can contain large quantities of toxic heavy metals such as lead, zinc, or chromium, as well as organic compounds that are particularly hazardous to the environment, such as PCBs and carcinogenic PAHs. Before remelting, steel must be cleaned of its treatments during recycling. Paints, plastics, and other contaminants are therefore removed through chemical or mechanical processes. Steel recycling rate after treatment: 78%

​​​​

Aluminum must be chemically stripped of its surface treatments and is 100% recyclable, with only 37% actually being recycled.

STAINLESS STEEL is infinitely recyclable and is largely, if not entirely, recycled. It requires no painting due to the inherent properties of the material. In the construction and building sector, stainless steel recycling reaches 100%.
