Rayner to Lower Carbon Footprint by More Than 800 Tonnes Over 5 Years

Posted on 22/07/2020

For immediate release

Worthing, UK, July 22, 2020 – Rayner, the only UK manufacturer of Intraocular Lenses (IOLs) for treating cataracts and a winner of the 2020 Queen’s Awards for Enterprise (Innovation), announced today that changes to their manufacturing and packaging procedures will reduce CO2 greenhouse gas emissions by more than 800 tonnes over the next 5 years.

The reduced CO2 greenhouse gas emissions are the result of three dedicated waste-reducing projects:

  • Revising manufacture of the RayOne Hydrophobic IOL so that 26,200 litres of Isopropyl alcohol (IPA) will now be internally recycled annually (saving 91.9 tonnes of CO2 greenhouse gas emissions annually); Rayner also wanted to reduce IPA consumption so it could instead be diverted to medical hand gel manufacturers to help combat COVID-19.
  • Completely removing single-use plastic from its IOL manufacturing process, saving 7 tonnes of plastic/14 tonnes of CO2 greenhouse gas emissions annually.
  • Updating packaging across the entire RayOne IOL portfolio, saving 27.8 tonnes of single use plastic/55.5 tonnes of CO2 greenhouse gas emissions annually.

The above annual savings figures have been averaged out based on projected 5 Year volumes.

Rayner CEO, Tim Clover, said “Everyone at Rayner takes our responsibility to reduce waste and the use of plastics seriously. Furthermore, this is something we know surgeons and patients also care deeply about. By careful re-design and bold decisions, we have been able to retain all the features of RayOne which make it so popular, but dramatically reduce its environmental impact. Surgeons can expect to see the updated RayOne packaging over the next few months.”

Rayner continues to look for waste-reduction opportunities and has already introduced changes within its global head office in Worthing, including: switching to recycling collectors that send zero waste to landfill, and introducing reusable cups for every member of staff, saving almost 120,000 disposable cups annually.



Concern for Ophthalmic Surgery Sustainability

In a weekly poll of US eye surgeons by Market Scope, almost 30% of respondents rated their concern on the impact of waste being produced from ophthalmic surgery as 5 (very concerned) on a 1-5 scale1.

Addressing the issue in the UK, The Royal College of Ophthalmologists published an Ophthalmic Services Guidance, “Sustainability in Ophthalmology” in 2013 2.

Method for Calculating CO2 Greenhouse Gas Emissions Figures

To calculate CO2 greenhouse gas emission figures for plastic, Rayner used 2 kg CO2 per kg plastic produced3.

CO2 greenhouse gas emission figures for IPA were calculated at 3.5 kg CO2 / Litre4.
