Sustainability & Circular Economy

Working with Nature, Not Against It

Sustainability has always been at the heart of AppleOak FibreWorks. From the water we use to the plants we grow, the dyes we extract and the materials we choose, we believe that working with natural colour should mean working with nature, not against it.

Natural dyeing is often described as sustainable, but the reality is more complicated. Dyeing requires water, energy and resources, and simply replacing synthetic dyes with natural ones does not automatically make a process environmentally friendly.

For us, sustainability has never been just about the dyes themselves. It is about the entire process, the decisions we make every day and our willingness to continually improve.

And now, as AppleOak moves into a new chapter, we're bringing everything a little closer together — quite literally.

Coming Home — A New Chapter for AppleOak

After many years of working from a separate dye studio, we are moving AppleOak home, bringing our work back into the heart of our dye plant garden in County Clare. Though this wasn't the original plan, we are now working on making the most of it!

Our new setup will bring together a converted container studio, polytunnels, dye vats, pigment extraction, dye plant cultivation and educational activities within one connected space.

It is a smaller operation in many ways, but one that allows us to work more closely with the land and the seasons.

Instead of travelling between our home, garden and studio, much of our daily work will now happen in one place. Harvested plants can move directly from the garden to the extraction area, and the resulting dye matter can return to the compost.

Our fermentation vats will sit within the polytunnels, making use of the naturally warmer environment while allowing us to monitor and support the conditions needed for fermentation.

We are also reducing our general textile retail range, allowing us to concentrate on natural dyes, dye plant cultivation, pigment production, education and a carefully selected range of natural materials.

For us, this is not simply a relocation. It is an opportunity to bring the different parts of AppleOak together into a more connected, practical and sustainable way of working.

Rainwater — Our Most Valuable Resource

Water is one of the most important resources in any dye studio, and reducing our dependence on treated mains water has been a priority from the beginning.

Living in the west of Ireland, we are fortunate to have plenty of rainfall. Natural dyeing also benefits from the characteristics of soft rainwater, which can be particularly useful when working with plant dyes.

Our previous studio operated using harvested rainwater, with a storage capacity of approximately 4,000 litres.

As we establish our new home studio, rainwater harvesting will continue to be central to our work.

By collecting and storing rainfall, we aim to meet our dyeing and extraction needs without relying on mains water, while using water as thoughtfully and efficiently as possible.

Keeping Dye Water in the Cycle

One of our greatest challenges has always been what happens to the water after dyeing.

Even when working with natural dyes and carefully selected mordants, wastewater needs to be managed responsibly.

At our previous studio, we invested considerable time and resources into developing a biological wastewater treatment system, designed with the help of engineer Ollan Herr from Herr Ltd.  

Used dye water passed through a series of settlement tanks and planted gravel and sand filters before being distributed into an evergreen woodland, where the trees and surrounding soil provided further biological treatment and water uptake.

The system enabled us to manage the considerable water volumes associated with our former production studio.

Our new home and garden setup will use two different approaches to managing wastewater.

The home dye studio will continue to work with harvested rainwater, but its used dye water will be discharged through the mains wastewater system, subject to the appropriate wastewater requirements, simply because we have no space for the large filtration units at home.

Our garden-based indigo fermentation vats and pigment extraction area, however, will operate on a more circular system. We are developing a smaller, integrated water treatment and reuse system, building on the principles of our previous installation.

Here, the aim is to treat the water from our indigo and pigment extraction processes and return it to the garden for irrigation.

By placing our growing, harvesting, fermentation and extraction activities together, we can create a much closer relationship between the water we use and the plants we cultivate.

It is an approach we will continue to develop, monitor and refine as the new studio takes shape.

From Dye Plant to Compost and Back Again

One of the most satisfying parts of natural dyeing is that the process does not necessarily end when the colour has been extracted.

Our wormery has been an important part of AppleOak for years, helping us turn suitable spent dye plant material, cardboard and other organic matter into valuable compost.

Depending on conditions, our larger worm composting bins can take approximately six months to produce finished compost.

That compost then returns to the garden, feeding the soil in which we grow our dye plants.

With the garden and studio now coming together at home, this cycle becomes even more immediate.

From soil to plant, from plant to colour, and back to soil again.

It is one of our favourite examples of how a more circular approach can work in practice.

Growing Our Own Colour

In 2024, we began expanding our organic dye plant cultivation and seed production, building on many years of experience working with natural dyes.

Our initial growing trials focused on some of the most important historical dye plants, including woad (Isatis tinctoria), Japanese indigo (Persicaria tinctoria), madder (Rubia tinctorum) and weld (Reseda luteola).

Growing our own dye plants allows us to understand the entire process, from the health of the soil and the conditions of the growing season to harvesting methods, pigment content and colour extraction.

It also gives us opportunities to experiment, observe and develop more efficient ways of producing natural colour.

As our home studio develops, growing and processing dye plants will become increasingly interconnected, with dedicated areas for cultivation, fermentation and pigment extraction.

For us, understanding colour begins long before a dye bath is prepared.

It begins in the soil.

Saving Seeds for the Future

Seed saving is an essential part of our garden and an important part of our commitment to long-term sustainability.

Tristan is an experienced organic and biodynamic gardener with a professional background in seed production and horticulture.

Rather than relying entirely on purchased seed each year, we produce, harvest and store our own seeds wherever practical.

This allows us to better understand the life cycle of our dye plants, observe their adaptation to local conditions and maintain seed for future growing seasons.

Our seeds are used in our own garden, shared through our educational work and, where available, offered for sale.

Through the Natural Dyers & Growers Academy, we also encourage others to explore seed saving as part of the complete journey from seed to dye and back again.

Energy, Heat and Thoughtful Production

Natural dyeing often involves heating large volumes of water, so energy use is another important consideration.

Over the years, we have worked to reduce unnecessary heating through carefully managed extraction times, lower-temperature processes where appropriate and well-insulated dye baths and vats.

With our new polytunnel studio, we plan to make use of the naturally warmer growing environment to help maintain fermentation conditions, with additional temperature control where required.

One particularly exciting development is our work on extracting woad pigment using cold water — the result of years of experimentation and research.

We hope this process will contribute to more resource-efficient approaches to woad pigment production.

There is still more work to do, particularly around energy use, but reducing our dependence on unnecessary heating remains an important goal.

Less Waste, More Thoughtful Choices

Sustainability also influences the materials we sell, the packaging we choose and the way we operate our business.

Where possible, we favour natural materials, recyclable or compostable packaging, and products chosen for their quality and longevity.

We continue to look for ways to reduce unnecessary packaging, reuse suitable materials and minimise waste.

Sharing Knowledge

We believe sustainability is not just about what happens within our own studio. It is also about sharing knowledge and helping others develop thoughtful, responsible practices.

Through the Natural Dyers & Growers Academy, our workshops, courses, garden tours and research projects, we share our experiences of natural dyeing, pigment extraction, organic gardening, seed saving and the practical challenges of working sustainably.

I am sorry to say, that we do not have all the answers, but our methods continue to evolve. :)

But we believe there is enormous value in being open about what works, what doesn't and what we learn along the way.

Always a Work in Progress

Sustainability is not a destination we expect to reach one day. It is an ongoing process of questioning, experimenting, making mistakes and finding better solutions.

Bringing AppleOak home gives us the opportunity to rethink how the entire business works — from the garden and dye vats to water management, waste, energy and education.

Our new space will continue to evolve over the coming years, and we look forward to sharing both its progress and its challenges.

Thank you for following our journey and for supporting a more thoughtful way of working with natural colour.
