Kohler Mira, a prominent manufacturer of shower trays, has recently undertaken a noteworthy initiative to minimise its ecological footprint by launching 100% recyclable cardboard packaging for all its Mira shower trays. This new packaging replaces the formerly used expanded polystyrene (EPS), which has raised significant environmental concerns despite its low cost and protective qualities. The switch is part of Kohler Mira’s ongoing sustainability efforts and is projected to save around 100 tonnes of plastic and reduce CO2 emissions by 138,761 kg annually.
The shortcomings of EPS, including its low recycling rate and potential lifespan of up to 500 years in landfills, prompted the company to seek a more sustainable alternative. Additionally, the production and disposal of EPS contribute to high CO2 emissions and pose risks to wildlife.
Starting in April 2023, the company will ship Mira shower trays in packaging sourced from 100% FSC-accredited woodlands. This cardboard material is fully recyclable and maintains the robustness required to ensure that the shower trays reach customers in pristine condition.
At Kohler Mira, product quality and customer experience are paramount. The new packaging has undergone rigorous testing to ensure it meets our high standards while being environmentally responsible. The transition to recyclable cardboard will eliminate all nonrecyclable plastic from each tray’s packaging, resulting in a significant annual reduction in plastic waste and CO2 emissions. For a single new build customer, this already accounts for a savings of approximately 26,500 pieces of EPS plastic and about 10,600 kg of CO2 within this year alone, a testament to our commitment to our customers and the environment.
In summary, Kohler Mira’s transition from EPS to recyclable cardboard packaging is a significant step towards its sustainability goals. The immediate and tangible benefits, such as reduced plastic waste and lowered carbon emissions, underscore their ongoing commitment to offering quality products in a responsible and eco-friendly manner. They are confident that this change aligns with their stakeholders’ values and our shared vision for a more sustainable future.
