We know that we are still wearing garments that have polyester or poly blends such as school uniforms, workwear or that fabulous 70s dress that you love & still looks amazing (because it may last 100-200 years). 

But every time we wash these garments (whether its made from virgin synthetics or recycled rPET fabric) its doing untold damage to the environment plus impacting animal and human health.  So STSC is promoting and highly supporting the Guppyfriend Washing Bag as the frontline help in minimising the shedding of these plastic microfibres.  Its not a 100% solution, and so while we work to replace these fabrics, lets at least minimise their impact.  Read more here from Science Daily.

Two key benefits of a Guppyfriend Washing Bag is that a. it minimises the agitation of a garment which will lessen the shedding and will help preserve your garment longer; and b. captures many of the plastic microfibres.


This specialised washing bag was invented and sold by Langbrett Gmbtt whose profits from selling the washing bags go to the non- profit STOP! Micro Waste
which goes towards micro pollution education and research. 


STSC support the non-profit StopMicroWaste! movement plus are raising awareness via fashion labels, businesses and School P&Cs, 


Contact directly for any retail order enquiries and to ask for pricing per Carton for a box of 24.

Alison from STSC and her 11 year old son Watson have started @circularschools to educate on the circular economy and help reduce the plastic microfibres going into the ocean from most school uniforms. 

We are designing a Business and School Education Kit plus offer Skype and in-person school talks to help spread the word and help P&Cs to raise funds for their school. Please contact Alison for further information.

"The Guppyfriend wash bag is the original practical way to prevent microfibres from entering marine environments. Its smooth surface results in fewer fibre losses, helping your garments to last longer.  The microfibres released during washing are captured inside the bag. Guppyfriend will hold a couple jackets, or several pieces of swim and active wear."


TIPS TO REMEMBER and links below.

  • All synthetic fabrics shed plastic microfibres, whether made from virgin or recycled rPET.  Recycled plastic fabric still sheds "50% less than virgin fabric" however we believe that us and the environment deserve 100% of our support, especially when my work through the Circular Centre is helping to remove these textiles from the fashion supply chain and safely repurpose them into high quality products using waterless systems that cannot be put in a washing machine.

  • The best way to support the environment, animals and human health is to not purchase and wash any of these fabrics and focus more on wearing natural fibres.  Note that most textile Mills do not produce this fabric closed-loop therefore it sheds toxic microfibres in the millions during production that are washing into waterways.

  • The reality is that there are many garments still made from these fabrics and its frightening that designers are still using them.  See below for some very worrying research. Everyday garments include school uniforms, work gear, active wear and that fabulous vintage dress you love from the 70s (because it will last and shed for 100s of years).  So for these garments we need to wash them inside a Guppyfriend.

  • The Guppyfriend is not 100% fool-proof in capturing microfibres however another key benefit is that it minimises the garment's agitation in your washing machine so it will shed less plus this helps to prolong the life of your garment, and those two things alone are enormously beneficial.

  • In my opinion we should never recycle polyester or plastic bottles etc to return to the fashion supply chain unless its a product that does not need washing.  There are many other high quality products where we can safely re-use this plastic (see Circular Centre).  And especially everyday garments that need to be washed regularly or fleece, like a poly fleece bathrobe, as it releases the most microfibres.

  • Note, the Guppyfriend bag does not prevent textile colours from mixing when in the bag, its just like if you mix them in your washing machine. This also means that the colour of the bag may change due to the dyes in your garments. 

  • Washing Tips. Wash using cold water, on a short cycle and with eco-liquid soap as these help to also minimise shedding.

  • Where are they? Due to the reduction of agitation when using a Guppyfriend you may find it hard to locate large amounts of microfiber residue from the inside of the bag but they are there and as tiny as a human hair.

    To discard, you can scrape the lining with your finger nail or a paper towel to remove them and put into the garbage, remembering that its still going to landfill and possibly end up in the waterways hence the need for specific microfilters in washing machines and to not purchase new synthetics and only use rPET fabrics if they dont go into the washing machine (such as a raincoat).
