Recycled Plastic FAQs

Yes. Many Sebel products are manufactured using recycled plastic materials, or contain recycled elements. It's part of our ongoing commitment to reducing material waste and supporting more responsible production.

Recycled plastics are made from a blend of material sources, each with its own characteristics. As a result, natural variation in colour, surface texture and gloss can occur during the recycling and moulding process. These visual differences are normal and expected when working with recycled materials.

These variations do not affect product quality, strength or performance and are consistent with recycled plastic products across the industry.

Recycled plastic products can display natural visual variation as a result of the material and manufacturing process. These characteristics may include:

  • Slight variation in colour

  • Differences in surface texture

  • Areas of glossier or more matte finish

  • Subtle flow or weld lines

  • Minor sink marks in areas where material thickness changes

These characteristics are expected when using recycled materials and do not affect product performance, durability or quality.

Subtle marks such as flow lines, weld lines or faint surface variations can occur naturally during the injection moulding process. These may be visible where molten material flows and cools at different rates, particularly in recycled plastics.

In some cases, small sink marks may also appear in thicker areas of the moulding. These characteristics are normal, expected and purely visual. They are not cracks, faults or defects and do not affect the strength, performance or durability of the product.

No. All Sebel products, whether made from virgin or recycled plastic, are engineered, tested and certified to meet the same strength, durability and safety standards. Visual variations are purely aesthetic and do not compromise performance.

The visual characteristics described above are a normal and expected part of recycled plastic products and are not considered defects or grounds for return or exchange.

If you believe your product has a structural fault or performance issue, please contact our team and we will be happy to assess it in line with our warranty and returns policy.
