Sustainable resilient flooring

With so many options to choose from, there’s no excuse for not specifying green, says Hattie Hartman

When it comes to resilient flooring, numerous green alternatives to conventional products are available. Natural products, such as linoleum, cork and rubber, tick the important sustainability boxes: they are renewable and non-toxic.

Online specifying tool GreenSpec rates linoleum ahead of cork and rubber. FSC certification of cork forests and rubber plantations is in its infancy. According to Dalsouple, only one rubber source is FSC certified and its quality is not adequate for flooring. Dalsouple is working towards certification with a Malaysian supplier.

Linoleum is made entirely from renewable materials. One of its primary ingredients is linseed oil, derived from flax, sourced primarily in Canada and transported by tanker. Rubber and cork must also be sourced from abroad. Rubber comes primarily from south-east Asia and cork from Portugal, Spain and North Africa. That they are transported by ship mitigates the embodied carbon question, so issues of sustainable forestry and manufacturing processes take priority. Another issue to explore when specifying is the use of non-toxic binders, sealants and adhesives.

As important as the embodied energy of a flooring product is its durability and its environmental impact in use. Edo Ram, of manufacturer Forbo, notes that 60-70 per cent of the environmental impact of linoleum flooring is in maintenance and aftercare, rather than in sourcing or production. Forbo has invested in independent, third-party lifecycle analysis to clarify these issues and has set year-on-year targets for improvement.
