When it comes to sustainable farming, every bit of organic material matters. Yet there is one powerful by-product that too often gets overlooked: coffee chaff. This light, flaky substance, shed during the roasting of coffee beans, is full of untapped potential for farmers and gardeners who want to close the loop and grow better from the ground up.

At Reground, we are on a mission to change the way the world thinks about waste. That includes giving coffee chaff the respect it deserves. In this blog, we will show you why coffee chaff belongs in your soil, compost, and garden, and how you can get your hands on this unsung hero of regenerative agriculture.

What is coffee chaff and how can it benefit your farm or garden?

Let us start with the basics. Coffee chaff is the papery skin that comes off green coffee beans during the roasting process. Lightweight and dry, it often gets discarded. But smart growers know better.

Rich in carbon and packed with fibre, coffee chaff makes an excellent mulch, organic fertiliser, or compost ingredient. It breaks down easily, improves soil texture, and plays well with other organic materials. When used right, coffee chaff can enrich your soil without the need for synthetic additives.

Choosing to recycle coffee by using by-products like coffee chaff is a simple and powerful step towards circular agriculture. It is not just about reducing waste. It is about turning a by-product into a valuable growing resource.

How to use coffee chaff to enrich your soil

So, how do you use coffee chaff in your soil?

Firstly, coffee chaff is excellent for improving soil structure. Its fibrous texture creates space for air and water to move through the soil, which is essential for strong root development. When added to growing beds, coffee chaff increases moisture retention and helps reduce erosion in both dry and wet conditions.

Mix coffee chaff directly into garden beds or layer it beneath mulch to slowly feed your soil as it breaks down. For best results, combine it with other organic inputs like a well-balanced coffee compost bin setup or traditional garden compost.

You can also use coffee grounds in the garden alongside chaff to provide a complementary nitrogen boost and enhance microbial activity.

Using coffee chaff for gardens is not just about nutrients. It is about giving your soil the tools it needs to regenerate and thrive, season after season.

Coffee chaff as a sustainable composting resource

If you are building a compost pile worth bragging about, coffee chaff deserves a spot. It is a brilliant brown material, rich in carbon, that pairs beautifully with nitrogen-heavy inputs like food scraps or coffee grounds in compost.

Adding coffee chaff to your compost improves the balance between carbon and nitrogen. This helps accelerate decomposition and reduce odours. It also regulates moisture and airflow, which are essential for breaking down organic matter effectively.

When used alongside coffee husk, food waste, or green clippings, coffee chaff compost becomes a powerful mix that reduces landfill waste and creates a nutrient-dense material to feed your garden.

If you are just starting out, use a coffee compost bin as your collection hub. Layer coffee chaff, vegetable scraps, and garden trimmings. Turn it regularly and in a few weeks, you will have dark, rich compost that is perfect for your veggie patch or orchard.

Including chaff in coffee waste cycles is smart, sustainable, and surprisingly simple.

Why sustainable farmers love coffee chaff and why you will too

Sustainable farming is about working with nature. Using coffee chaff is one of the easiest and most cost-effective ways to do that. Whether you are regenerating pasture, building no-dig beds, or revitalising tired soil, coffee chaff for gardens is a low-input, high-return solution.

It also works brilliantly with other coffee by-products. For example, pairing coffee grounds in compost with coffee chaff compost creates a balanced mix of nutrients and texture. Think of it as coffee synergy in your soil.

There is also the environmental benefit. When you recycle coffee and its by-products, you reduce methane emissions, support local coffee roasters, and help build a more circular economy.

At Reground, we make sure materials like coffee chaff are put to good use where they matter most: back in the soil, not the bin.
