meeting the uk's demand for high quality biochar at scale

If you've heard of biochar, chances are you know it's a powerful way to boost your soil health. Just one application can improve how your soil holds onto nutrients and water - leading to stronger roots, healthier plants, and bigger harvests. That alone makes it a no-brainer for anyone who loves growing their own food, flowers, or even just a lush lawn.

But the benefits don’t stop there. Because biochar is made by locking away carbon that would otherwise be released into the atmosphere, it's also a simple and effective way to help the planet. It’s a rare win-win: healthier soil and a healthier environment.

And biochar isn’t just for soil anymore. From being used in sustainable building materials like concrete, to helping filter water, support insect farming, and even replace toxic foam products, biochar is making waves across industries. What started as a soil booster is now proving itself as a game-changer in eco-innovation.

Whether you're improving your garden or exploring biochar in bold new ways, we're focused on delivering biochar at scale, without compromising on quality or expertise.

Biochar at Scale

Biochar locks carbon away that would otherwise end up in the atmosphere, making it a powerful tool in the fight against climate change. At the same time, it’s helping farmers and growers restore soil health, boost productivity, and become more resilient to the changing climate.

And it's not just farms that are seeing the benefits. Biochar is starting to show up in other industries too, like construction and waste management, because it doesn’t just reduce environmental impact, it gets results. Whether it’s strengthening materials, filtering water, or reusing waste in smarter ways, biochar is proving to be a versatile and powerful material.

But, for biochar to make a real impact, it needs to be available in large enough quantities. That’s why it’s part of our mission to build the biochar market in the UK at scale, so that more people and industries can access it and put it to work.

In a world moving toward a circular, zero-waste economy, biochar is a simple, scalable solution that helps us all move forward.

Whether you’re a commercial grower, a landscaper, or working in an industry that's wanting to make better choices, biochar is one way you can take action that really matters.

High-Quality Biochar

If you’re using biochar for yourself or for a client, you want to know it’s doing what it’s supposed to - improving your soil, supporting healthy growth, and contributing to a more circular economy. However, not all biochar is made the same.

The quality of biochar depends on what it’s made from and how it’s produced. At Onnu Biochar, we make sure you’re getting the best through detailed research and testing. All our biochar is EBC certified (European Biochar Certificate), which means it meets strict standards for things like purity, consistency, and carbon content. In simple terms? You can trust that it’s high-quality and high in carbon.

Why does this matter to you? Because low-quality biochar might not give you the results you're hoping for. Worse, it could turn people off a product that’s actually a powerful tool in fighting climate change. That’s why certifications matter, and why we’re proud to offer biochar you can rely on.
