Sails.
There are millions of them in circulation on our planet, and just as many heading into landfill each year.
Currently, there aren’t any formal recycling schemes to be found anywhere in the world, but many small organisations are working with sail material to make new things. Whilst these efforts are noble, it’s clear this isn’t the long-term sustainable opportunity - environmentally or economically, and legislation is now rapidly changing.
In this episode, Dr. Joe Penhaul Smith and Sam Penhaul; one scientist and one sailor, discuss the chemistry of sail material and their efforts towards recycling sails, in the most direct meaning of the term ‘recycle’.

So far, the 'clean' in Clean Sailors has meant challenging ourselves and the sailing marine industry to become more environmentally aware and sound.
For this podcast, we are looking at ‘clean’ from another perspective...
Food at sea is very much fuel and certainly morale - hot, filling, long-burn energy loaded and as quick as possible to cook. When racing, well, let’s talk freeze-dried bags and a kettle of hot water!
But how can we become more nutritious at sea, and how can we satisfy all the above, without relying on bowls of pasta, tinned beans and in the extreme cases the Pot Noodle…?
Tune in to hear sailor, nutritionist and coach, Sarah Powell, on clean cooking and eating on a boat.

Now, The Turner Twins may need little introduction. With various adventures and accolades; land, sea and sky, they’ve tried, tested, endured and pushed both themselves and resources to the maximum.
Two years ago they set out to sail to the most remote part of the Atlantic – on a second hand boat, with an electric engine, testing hydrogen cells, new antifouling technology AND whilst supporting macroplastic research as they went, on an emission-free yacht.
So how did all this new technology fare underway?
Let’s hear more from these professional adventurers, Ross and Hugo.

As we know, sails are strong and durable, built to withstand some of Earth’s toughest environments; UV light, saltwater and wind.
Made from complex synthetic materials, sails aren’t formally recycled anywhere in the world with over 97% of them heading to landfill or incineration.
But what if we used these huge sheets of hardy textiles for good?
What if we used spent sails to help shelter refugees, the homeless and those displaced by politics and natural disasters?
In this episode we are joined by Angela Abshier, founder of Sail to Shelter, achieving just that.
A worthy listen, I'm sure you will agree.
And, if you've an old sail remember to head to our ReSail by Clean Sailors platform to find your closest drop-off. Old sails can be made into new things 👍

End of life boats...
With an estimated 30,000 tons of composite waste from old boats being discarded in European landfills annually, alone, we know this continues to be an issue or an opportunity for the marine industry and beyond.
In this episode host Holly is joined by Jeroen Wats, former champion sailor and now composite revolutionist to discuss the environmental impact of composite materials and how, through his company, ExoTechnologies, he's looking at the state of art solutions to address the problem, namely a bullet-proof, lightweight, super strong and fully recyclable composite.

Now, we know since the 1950’s, GRP and FRP hulls – glass and fibre reinforced plastics, became the go-to for boat building.
These materials were revolutionary, not just for maintenance, cost and performance, but also increasing the accessibility of boats to a much wider audience.
Fast-forward several decades, and these materials; meaning thousands and thousands of boats, are at end-of life, with no formal recycling opportunities anywhere in the world….
So, what currently happens to boats when they die? And what impact are they having on the environment?
Listen in to hear Dr. Corina Ciocan - Principal Lecturer in Ecotoxicology/Marine Biology at the University of Brighton speak about her somewhat alarming research on our choice boat-building materials and our marine environments, plus our human health...

We've had a couple of conversations on the topic of end-of-life boats, notably with brilliant minds and teams who are working to create fully recyclable composites from which to build new vessels going forward.
So, what about those boats already in existence? What of those boats that are currently abandoned on shorelines globally due to no formal recycling, clear procedures, incentives or supporting legislation when it comes to end of life?
Guillaume Perben, CEO and co-founder of a Swiss based company with a global mindset aptly named ‘Composite Recycling’, joins us for this episode of the Clean Sailors podcast.

Now, the golden rule when spending time in the sun is to cover up and sunscreen up. These tips are generally the best when it comes to protecting our skin from potentially harmful UVA and UVB rays and any secondary health impacts they can cause such as skin cancer.
These tips are well known, however perhaps less known is the harmful effect that personal care products including sunscreen can have on our marine environment.
In this episode, hear Stuart Knowles, Founder of ocean-minded sunscreen, Himaya, speak about the health of our oceans, building an environmentally focussed business right through the supply chain, and the best sunscreen to be using (*clue in the title!).

Freya Terry is a 22-year-old female solo sailor making her way around the UK and Ireland. Aside from this exciting and lengthy journey of 2300 nautical miles, Freya is raising awareness of mental health as she goes. It’s foggy Sunday morning, and we are snug in the cabin of her 31ft boat, a beautiful Sparkman and Stephens SHE, doused in bright pink.
Listen in to hear about Freya's solo-sailing accomplishments, her big ambitions, why the topic of our mental health is the message she is spreading as she goes, as well as how we can support each other in discussing the same.

What exactly is seagrass and why is it important? How do we sailors impact the seabed, and what can we do about it?
Tune in to hear a conversation of experts around our joint #ProtectOurBeds campaign - why seagrass is an instrumental species for our planet, how it's threatened and how we sailors can find out exactly where it lies, when out on the water.
With the Ocean Conservation Trust, savvy navvy and Falmouth Harbour.

As sailors, the sea is our pleasure, our passion and our pastime and for many - profession. Who better, then, to help protect the health of our waters than sailors...
In this episode, host, Holly, is joined by Theresa Zabell OLY; two-time Olympic gold winning sailor, with five world championship titles and one silver, three European titles, 14 International Olympic weeks and 13 National Championships under her belt, who, for over twenty years, has been been educating and inspiring young people on ocean pollution and conserving our seas through her Ecomar Foundation.
From rising to meet the Olympic standard in sailing to helping address the global challenge of ocean health, hear Theresa discuss her golden achievements and how we all play a role in improving and preserving our watery environments, worldwide.

Our polar ice caps are probably the most referred to, as a proxy for the alarming temperature changes of our planet. These large sheets of ice, as preserved for millions of years, have been undergoing change, so much so that once impassable and certainly inhospitable areas of our globe are opening up.
Host, Holly, is joined by Ella Hibbert, a sailor who and in just a few short weeks will slip lines, alone, for the Arctic Circle, attempting the worlds- first single-handed non-stop circumnavigation of the Arctic.
But, in her own words – ‘this is not a record attempt, it’s a wake-up call’.

During the 1950s, glass fibre reinforced polyester (GRP/FRP/fibreglass) composites displaced wood as the material of choice for boats as it permitted easier manufacture, smoother hydrodynamic surfaces and significantly reduced the maintenance costs.
Such materials revolutionised not just the production of vessels, leisure in particular, but also the accessibility of boating to a much wider audience. However, the durability of the composite materials is now becoming an issue given that many boats are no longer required and disposal is not trivial.
In this episode, podcast host, Holly, is joined by two teams changing the way boats are built. Listen in to hear how material science is revolutionising recyclability in boat-building with a view to solve the end-of-life problem, with guests Alessandro Stagni from NL Comp and Patrick Pacchetti from RECARBON.

Sails, like many things, have a long history. From papyrus leaves or animal hide rigged to catch the wind to today's highly complex highly engineered sail cloth, designed to withstand some of the toughest environments on our planet. With no formal recycling for end-of-life sails, anywhere in the world, we speak with Dede De Luca, Co-founder and CEO of OneSails, on the evolution of sail technology, why end-of-life materials are so complicated, and his top tips for looking after our sails.

Did you know that each year, in the UK alone, we flush more than 22,000 tonnes of glue down our loos? Each time we flush toilet paper, we are potentially adding thousands of microplastics to our waters. Joining our host, Holly, is Dave Hamlet, Managing Director of Tanki, the glue-free toilet roll , to discuss the makings of toilet roll, the impact of our daily flushes on our waters and how a simple switch by us all, on land and at sea, can help lessen our impact.

It’s easy to think that all fish belong in the sea. But not all fish belong in all parts of the sea….
Threatening local ecosystems, disrupting and at times eradicating other species entirely and even disrupting economies, our boats, large and small, can transport different creatures around our waters, and at times, across whole oceans.
In this episode, we’ll be looking how species spread across our planet, just what this costs us and how the warming of our oceans is likely to make this even more pronounced..
Joining our host, Holly, is marine spatial ecologist and all-round conservation superstar, Dr Alexandra Davies. She is a postdoctoral fellow at the University of Alberta and a true expert on this very matter.

'Microplastics' - we've all heard of them and over the last two years alone, have become aware of just how pervasive these tiny pieces of plastic are within our environment, and our human bodies… In this episode, we speak with Dr. Christopher Pham and Dr. Roman Lehner, two eminent scientists who study the very topic of microplastics, to help us better understand the plastic soup upon which we sail, soup we can’t see so well from above the waterline. Focusing on our recent sailing expedition mid-Atlantic, around the plastic-rich waters of the Azores, we look at how microplastics are created, just how far they have got, and Dr. Lehner’s pioneering research on how they may be interacting with our very cell structures…

For thousands of years, we've been building boats. We began, and indeed continued for centuries, with wood, but since the mass-commercialisation of plastic since the late 1940's, we've been making boats from glass or fibre-reinforced plastics.
Building new boats this way is carbon-intensive plus there is little, if any, formal process in the world for these huge plastic hulls when they come to the end of their lives.
In this episode, we speak with Friedrich Deimann and his Co-Managing Director, Jan Paul Schirmer, of Greenboats - a German-based team with big ambitions, building boats in a cleaner and more efficient way.

Our emission of greenhouse gases, namely significant amounts of Co2 over several hundred years, is altering our climate. We often turn to trees and replanting vegetation, Green Carbon, as the opportunity to recapture carbon from our atmosphere, but coastal ecosystems are exceptionally apt at carbon capture and storage, too - almost more effective than the Green Carbon counterpart.
In this episode we speak with Lucy McMahon, Marine and Coastal Scientist and ocean optimist, about Blue Carbon; what it means, how effective our Blue ecosystems are at moderating our planetary climate, and why we need to protect them.

With studies showing that traditional antifoul paint on the bottom of our boats is contributing extraordinary amounts of chemicals and microplastics to our waters, the case for biocide-free and paint-free solutions is high. In this episode, we speak with Dr. Rik Breur, winner of the European Inventor Award 2019, material scientist and founder of revolutionary antifoul product, Finsulate, about why we should care about our bottoms and how nature inspired his solution to this ocean pollution problem.
