The agricultural sector in Spain, and more specifically in Andalusia, has just taken a giant leap forward. The company Carboliva has achieved CE marking for its biochar, obtained from pruning waste and olive pits, making it the first Spanish biochar to be approved as an official fertilizer in the European Union. This is no small matter, as it means that this material is no longer seen merely as a byproduct but has now entered the catalog of harmonized fertilizers that can be sold without restrictions in the 27 member states.
The key to this recognition lies in strict compliance with Regulation (EU) 2019/1009 , legislation implemented a couple of years ago to regulate the fertilizer market and promote the use of recycled materials. For a product to obtain this certification, it's not enough to simply claim it's good; it must demonstrate that it's safe for people and the environment, free of contaminants, and that its nutrient levels match the label specifications. By passing this rigorous test, olive biochar positions itself as a guaranteed quality option with full traceability for any European farmer.
A local solution to the chemical fertilizer crisis
Given the current international climate, with soaring energy prices and geopolitical tensions driving up gas costs, traditional chemical fertilizers like urea have become incredibly expensive. In this context, having a product manufactured locally, using biomass from our olive groves, is a real lifeline. By investing in this technology, we foster a genuine circular economy that reduces dependence on imported inputs, offering farmers a much more stable and predictable price.
The great thing about this biochar is that it's not only suitable for traditional farming, but it has also been approved as an input for organic agriculture . This opens up a huge range of possibilities, as it can be used on all types of farms without fear of losing organic certifications. Álvaro Espuny, the company's CEO, is clear that this advancement proves that what was once waste can be transformed into a highly valuable resource that benefits both the producer's bottom line and the health of the soil.
Properties that make the land and climate fall in love.
If we get down to brass tacks about what biochar does in the soil, it's practically like a magic sponge. Thanks to its porous structure, it's able to retain water and nutrients much better, preventing them from being lost to the deeper layers of the soil when it rains heavily or is irrigated. This is especially useful in the drier areas of Spain, where every drop counts, helping plants better withstand periods of water stress and making the most of every last gram of fertilizer applied in both dryland and irrigated farms.
But biochar is also an unexpected ally in the fight against global warming. By burying it in the soil, we create a stable carbon sequestration system that remains there for centuries instead of rising into the atmosphere as CO2. It is one of the most promising carbon removal techniques currently available. Therefore, its use fits perfectly with the new requirements of the Common Agricultural Policy and European strategies that urgently call for more sustainable agriculture that helps cool the planet naturally.
A rigorous and transparent validation process
Getting here hasn't exactly been a walk in the park. Carboliva has had to undergo very detailed audits by CAAE , scrutinizing everything from the origin of the raw materials to how the temperature is controlled in the pyrolysis ovens. Exhaustive analyses have been carried out to confirm the homogeneity of the product, ensuring that every bag leaving the factory meets the same safety standards for human health and the environment, preventing any presence of heavy metals or harmful substances.
Obtaining this CE marking marks a turning point in how we understand fertilization in Spain. With such solid legal backing, olive biochar ceases to be a technical curiosity and becomes a strategic tool for 21st-century agriculture . Its implementation is expected to grow exponentially in the coming months, especially in areas that need an extra boost in fertility and greater moisture retention, establishing itself as a shining example of how local innovation can address the major challenges of the European market.
This breakthrough confirms that utilizing olive grove waste is not only possible, but is the path forward for achieving true fertilizer sovereignty in Europe. By combining agronomic advantages with environmental protection, this new CE-marked biochar ensures that agricultural professionals have access to a local, safe, and highly effective solution for improving their harvests without compromising the future of their land.
