In a previous post; ‘Its All About The Carbon’ we described our work with The University of Exeter and The Tevi fund to produce our first pass Life Cycle Analysis. This is work to prove the benefits of using our material vs reference data on first use or ‘virgin’ nylon 6.

The resuts are in.

Quoting from the report provided by academics following ISO 14040:2006 LCA principles and framework, and working within the Environment and Sustainability Institute (ESI) of The University of Exeter;

“The carbon footprint of the Fishy Filaments™ recycled nylon is estimated to be 0.201 kg CO2-eq per kg produced, relatively low compared with virgin nylon based on existing datasets in LCA databases”

“The CML (version 2001-Jan 2016) life cycle impact assessment method was used to calculate the following 11 environmental impacts: Abiotic Depletion Potential (Elements) (ADP elements), Abiotic Depletion Potential (Fossils) (ADP Fossils), Acidification Potential (AP), Eutrophication Potential (EP), Freshwater Aquatic Ecotoxicity Potential (FAETP), Global Warming Potential (GWP), Human Toxicity Potential (HTP), Marine Aquatic Ecotoxicity Potential (MAETP), Ozone Layer Depletion Potential (ODP), Photochemical Ozone Creation Potential (POPC), and Terrestrial Ecotoxicity Potential (TETP).

The key impact GWP (Global Warming Potential) is …. 0.201 kg CO2-eq per kg of Fishy Filament Nylon PA6.

To put these results into context, the GWP of 1 kg of virgin Nylon 6 produced in Europe is 6.52 kg CO2-eq based on the GaBi dataset (EU-28: Polamide 6 (PA6) PlasticsEurope) and 9.28 kg CO2-eq based on the Ecoinvent dataset (RER: nylon 6 production)

This is a great result for our customers.

They can now report with confidence that by using Fishy Filaments nylon instead of virgin material they are avoiding 97-98% of the Global Warming impacts associated with that first use nylon.

This implies that a manufacturer of, for example, shirt buttons could equip 5 whole dress shirts using buttons made of our recycled nylon for the same environmental cost as a single button made in, again for example, China.

That’s 46 buttons made from our recycled nylon vs a single solitary button made from newly created nylon.

46 to 1 !

The environmental cost differential is now clear.

As our process develops and scales up we expect to revisit this work and for its detail to inform that development, focussing our engineering skills where they are needed most. For us it is not quite ‘All About The Carbon’ but hard data from independent experts is badly needed if our economy is to complete its switch to a low carbon footing.

Companies can now make a rational choice between different sources of nylon based on this new data and our independently tested mechanical performance.
