Sustainability is an integral part of Weener Plastics’ strategy. Innovative technologies, low-carbon materials and smart product designs are essential drivers in our approach to minimizing environmental impact. Weener Plastics (WP) also recognizes that convenience and quality are fundamental and should not be compromised. Respecting sustainability as well as functionality, WP’s Innovation & Development team has developed an unprecedented solution: the world’s first 100% recyclable valve.

Numerous brand owners and packaging professionals will be aware of the fact that silicone valves provide excellent functionality in caps and closures. However, the recyclability of these valves is generally compromised. Several alternatives have been launched on the market, but none have managed to replace the traditional silicone valve. For example, floating silicone valves are not recyclable and prevent brand owners and private labels from claiming their products can be recycled 100%. Valves made of TPE are not 100% recyclable, or don’t offer the same performance as tried and tested options. For years, there has been an urgent need for a good alternative.

100% recyclable

Following extensive research, trials, laboratory tests, and (internal and external) consumer reviews, WP’s Innovation & Development team has created the perfect solution: a 100% recyclable valve that offers fully controlled, clean dispensing. WP’s fully recyclable valve is made of a specially developed material. This enables full recycling with polyolefin waste streams – regardless of the bottle material. A renowned independent research institute has confirmed the 100% recyclability of this new valve.

Uncompromised functionality

This recyclable valve is functional in every way. It offers a fully controlled and clean dispense of any quantity the consumer may require. The dosing behaviour can also be adjusted, depending on preference. What’s more, valve dimensions are exactly the same as those of WP’s familiar silicone valve: the new valve fits in all of WP’s existing MaxiDose valve closures. Furthermore, the valve is also perfectly suitable for customized designs.

Widely applicable

WP’s new valve is highly versatile and compatible with a wide range of applications such as food, home care and personal care. When used to dispense oily or fatty formulations, this recyclable valve also performs better than any other solution – in fact it’s even suitable for olive oil. Especially when controlled dispensing is essential, for example with concentrated formulations, this valve provides the ideal solution.

The 100% recyclable valve is one of WP’s green initiatives. These are part of the circular economy programs WP has initiated. The Innovation & Development team converts sustainability challenges into new opportunities to stimulate circularity. WP’s new developments enable customers and consumers to contribute to a more sustainable future.
