Turning the recycled phosphorus of RevoCaP into agricultural solutions 

RevoCaP – the high-quality phosphorus produced through EasyMining’s proprietary technology – is entering the initial stages of commercialisation. It’s a critical part for introducing any new product and a major milestone in the journey to bring new levels of circularity to agriculture.  

A non-crystalline calcium phosphate, RevoCaP is the end result of the EasyMining-developed Ash2Phos process for extracting phosphorus from incinerated sewage sludge. It’s a highly pure form of the vital nutrient and has multiple potential applications in the agricultural industry. In mid-2025, RevoCaP was approved by the European Union for organic farming, and development was soon underway to fully explore its direct usage as a slow-release fertiliser for that market, as well as other uses.        

The go-to-market plan for RevoCaP, however, still needed to be fully fleshed out. In September, Asko Kinnunen came on board as EasyMining’s newest product manager for nutrients. Based partly in Finland, Kinnunen has experience in developing circular-based fertilisers and harnessing the circular economy for agriculture.  

– We’re at the commercialisation point in the process now, which is very important. It’s drawing nearer to when the first RevoCaP-based product will be available, and it’s quite realistic to say we will see RevoCaP in a farming application by 2028, he says.

Recycled phosphorus with multiple advantages

RevoCaP’s distinct characteristics make it optimal for a variety of product implementations. Since it’s already approved for organic farming, Kinnunen says that’s the most obvious use case, especially given RevoCaP’s high concentration of phosphorus. 

– Typically, the fertilisers for organic farming are byproducts, such as manure and digestate. These agricultural inputs are not only low in essential nutrients for growing food, but their levels also can’t be adjusted. That makes RevoCaP an ideal solution for applications that need extra phosphorus, he says.

Additionally, RevoCaP is a more environmentally responsible alternative to mined phosphate, the standard nutrient source in fertiliser production for conventional farming. It has a lower impact on the climate and lower levels of heavy metals like cadmium. This is in large part because RevoCaP is derived from a domestic source that exists wherever there’s a large enough population (sewage sludge) – while the mined phosphate that Europe almost entirely depends on is sourced outside the region, from countries like Morocco and Russia. 

Kinnunen, however, believes that RevoCaP’s status as reclaimed phosphorus is what will have the biggest appeal.

– I would say that this recycled aspect is the most important. This is not virgin raw material. It is fully circular. That is the key, he explains. 

But whatever application RevoCap targets – whether for organic or conventional farming – partnering with other companies, such as distributors or manufacturers, is a necessity and a core aspect of Kinnunen’s role.  

– The first very concrete step is to find the best potential partners for us - those who share EasyMining’s values and are interested in recycled products. Then we can evaluate and discuss together what the right position for RevoCaP is, he adds.

A product that appeals beyond borders 

Another major element of RevoCaP’s commercialisation is its test trial programme. Lab and greenhouse trials are already in progress, and field trials have also begun. The testing aims to collect a robust dataset on a variety of parameters – such as mixes, applications, materials, and more – to demonstrate its purity and safety for growing food. 

– We know quite well how RevoCaP performs. But we want to have a better understanding in terms of different applications and different crops. Because it’s totally new, we need additional data, Kinnunen explains.

And that data will be used for RevoCaP’s first marketing and education efforts in continental Europe, close to where the first Ash2Phos plant is currently being built in the German municipality of Schkopau.  

– Germany is one of the biggest organic farming countries in Europe. Austria is too. There’s also France. Still, the ultimate value of RevoCaP as a circular product goes beyond borders, Kinnunen emphasizes.

Nobody can afford to ignore the importance of circularity. It is not optional anymore. This is something we need to do, everyone, he says.

For Kinnunen, the rising urgency of the circular economy has become a pressing issue in farming and food production, requiring solutions that people can trust.    

– And RevoCaP is the answer because it is a truly unique innovation. We’re creating a product with very pure nutrients for many different applications in agriculture, Kinnunen concludes.
