Eco Coffin: A Gentle Guide to Sustainable Coffin Choices for Natural Burials

Choosing an eco coffin is an important step for individuals and families seeking a burial option that aligns with environmental values and a return-to-nature approach. Eco coffins offer a simple, sustainable alternative to traditional hardwood or metal coffins, allowing the burial process to remain entirely natural and supportive of the surrounding landscape.

This guide explains what an eco coffin is, the materials commonly used, the ecological benefits, and how to choose the right option for a natural or woodland burial.

An eco coffin is a biodegradable coffin made from natural, sustainably sourced materials that break down harmlessly in the soil. Free from toxic varnishes, plastics, and metals, these coffins are designed to support natural decomposition and protect the integrity of the burial environment.

Eco coffins appeal to people who value:

• Low-impact, environmentally responsible choices

• Gentle and natural aesthetics

• Burial practices that work in harmony with nature

• Simplicity rather than traditional formality

They are widely accepted — and often required — at natural burial grounds across the UK.

Natural burial sites focus on maintaining biodiversity, supporting healthy soil ecosystems, and safeguarding the wider landscape. Using biodegradable materials is essential to these aims.

Eco coffins help by:

• Avoiding synthetic materials that remain in the ground

• Preventing chemicals entering soil or groundwater

• Allowing the body and coffin to return naturally to the earth

• Supporting regenerative and conservation-focused landscapes

They ensure the burial process remains gentle, respectful, and environmentally aligned.

Eco coffins are made from a range of renewable, sustainable materials. Each has its own texture, appearance, and environmental story.

Cardboard coffin is one of the simplest and most sustainable options.

• Made from recycled or responsibly sourced paper

• Strong, lightweight, and fully biodegradable

• Usually the most affordable eco coffin choice

• Accepted in most natural burial grounds

The simplicity of cardboard often appeals to families seeking a gentle, minimalist option.

Willow is one of the most recognisable materials used for woven eco coffins.

• Extremely fast-growing and highly renewable

• Hand-woven using traditional craft techniques

• Breaks down quickly in the soil

• Adds valuable organic matter as it composts

Its natural appearance blends beautifully with woodland and meadow burial settings.

“Wicker” refers to the weaving method rather than a specific plant. Wicker eco coffins may be made from willow, rattan, bamboo, or similar fibres.

• Lightweight, breathable weave

• Fully biodegradable

• Supports healthy soil once decomposed

Because wicker materials grow quickly, these coffins are considered highly sustainable — but imported wicker (such as rattan) may carry a higher carbon footprint.

Bamboo grows rapidly and is extremely strong, making it a popular material.

• Renewable and naturally sturdy

• Clean, simple appearance

• Biodegradable and toxin-free

However, many bamboo eco coffins are imported from abroad, raising the carbon footprint linked to transportation.

Seagrass is a coastal marine plant harvested for its strong, textured fibres.

• Naturally biodegradable

• Woven into warm, organic-looking designs

• Contributes organic matter to the soil as it breaks down

Its gentle colour and soft weave make seagrass a beautiful, natural option for eco burials.

Rattan is a tropical vine known for its durability and natural flexibility.

• Fast-growing and renewable

• Biodegrades cleanly and enriches the soil

• Creates attractive woven designs

However, like bamboo, rattan is typically imported from overseas, increasing transport-related emissions.

Wool offers a softer, familiar alternative to woven or wooden coffins.

• Made from British wool with natural inner supports

• Gentle appearance, warm and understated

• Fully biodegradable

Wool eco coffins are valued for their comforting, non-traditional design.

Mushroom coffins — also known as mycelium coffins — are one of the newest innovations in environmentally conscious burial. They are grown, not manufactured, using mycelium, the root-like structure of fungi. When combined with natural fibres such as hemp, mycelium forms a lightweight, sturdy, fully organic coffin.

Key benefits of mycelium eco coffins:

• Exceptionally biodegradable — they break down quickly and cleanly

• Soil-enhancing — mycelium supports healthy microbial activity and may help enrich the soil

• Low-impact production — they are grown in moulds with minimal energy use

• Chemical-free — no varnishes, metals, glues, or synthetic components

Mycelium coffins are designed to create a positive ecological cycle: as the coffin decomposes, the fungi continue to support soil regeneration, making them one of the most environmentally progressive burial options available.

While they are still emerging in the UK funeral market, more natural burial grounds are recognising them as a promising, environmentally restorative choice.

A burial shroud is one of the simplest and most natural alternatives to a coffin. Shrouds are made from soft, biodegradable fabrics such as cotton, linen, bamboo, wool, or hemp. They gently wrap the body and allow it to return to the earth with almost no environmental impact.

Shrouds offer several benefits:

• They require fewer materials than a coffin

• They decompose very quickly

• They support the natural burial ethos of simplicity and minimal disturbance

• They blend seamlessly into woodland and meadow burial settings

Many natural burial grounds welcome shrouds, sometimes with a simple biodegradable board for safe handling and lowering into the grave.

Some woodland and natural burial grounds accept simple wooden eco coffins.

Choose options that are:

• Locally grown or FSC-certified

• Free from varnish, metal, and synthetic linings

• Made with natural handles (e.g., cotton or rope)

Softwoods such as pine are commonly used.

Selecting an eco coffin is a personal decision influenced by values, practical needs, and the requirements of the burial site.

Check the burial ground rules: Most natural burial sites have clear guidelines on permitted materials.

Consider locally sourced materials: Willow and wool often have a lower carbon footprint than imported bamboo or rattan.

Think about visual style: Some families prefer woven textures, while others choose smooth, simple designs like cardboard or wool.

Review cost and sustainability: Eco coffins vary widely in price depending on craftsmanship and material.

Prioritise full biodegradability: Ensure there are no synthetic linings, plastics, or chemical treatments.

Eco coffins contribute positively to the burial landscape by:

• Allowing natural soil processes to continue undisturbed

• Supporting healthy microbial activity

• Reducing the use of metals, varnishes, and plastics

• Lowering waste and carbon emissions

• Aligning burial practices with conservation efforts

These benefits make eco coffins a meaningful part of environmentally conscious funerals.

An eco coffin offers a gentle, sustainable way to honour someone’s life while respecting the natural world. Whether made from willow, cardboard, wool, seagrass, or another biodegradable material, eco coffins support healthier landscapes and align beautifully with the principles of natural and woodland burial.

Choosing an eco coffin ensures the burial process remains simple, natural, and environmentally thoughtful — a meaningful legacy for both the individual and the land.
