From waste to growth: ICL’s Puraloop^® recycled phosphorus fertilizer

With up to 85% of the world’s phosphorus reserves concentrated in just five countries, sustainable phosphorus management is essential for global food security. As a critical nutrient for plant growth, phosphorus plays a foundational role in food production. Fertilizers and food security are deeply interconnected, and Puraloop^® plays a key role in ensuring a sustainable phosphorus supply.

Traditional phosphate fertilizers are derived from non-renewable resources, with phosphate rock being listed as a critical material by the EU due to its limited availability and strategic importance. This reliance on finite reserves poses significant risks for long-term food security, making the need for sustainable alternatives like Puraloop^® more critical than ever.

ICL has responded to this challenge by introducing Puraloop^®, a groundbreaking fertilizer made by recycling phosphorus from organic waste streams. Puraloop^® is not just a product; it’s a visionary approach to addressing the global phosphorus crisis. By converting waste into a valuable agricultural resource, ICL is pioneering a sustainable path forward that aligns with the principles of the circular economy.

The Importance of Phosphorus Recycling

Phosphorus is indispensable for plant growth, driving everything from root development to energy transfer within plants. However, traditional sources of phosphorus, such as phosphate rock, are both finite and environmentally taxing. As the world faces increasing pressure to produce more food with fewer resources, the question arises: 

Can phosphorus be recycled? 

The answer is a resounding yes. Through innovative processes like phosphorus recovery and recycling, ICL’s Puraloop^® transforms waste into a valuable resource that supports sustainable agriculture.

Phosphorus recovery and recycling are essential strategies for mitigating the environmental impact of conventional agriculture. By capturing phosphorus from waste streams that would otherwise contribute to pollution, Puraloop^® provides a sustainable solution that reduces dependence on non-renewable resources. This approach not only conserves natural resources but also supports the broader goals of the circular economy, where waste is minimized, and resources are continuously repurposed.

Innovating with Phosphorus Recycling from Wastewater

One of the most promising developments in sustainable agriculture is phosphorus recycling from wastewater. Wastewater treatment plants generate significant amounts of sewage sludge, which have high moisture (90-95%) and can contain organic contaminants. For this reason, it often passes through a process of combustion for energy production, sterilization, and reducing its total volume. This process produces sewage sludge ash (SSA), which is rich in phosphorus. Traditionally, this ash would be discarded, contributing to environmental degradation. However, ICL’s innovative approach transforms this waste into a high-quality fertilizer through advanced phosphorus recycling techniques.

By focusing on recycling phosphorus residues from wastewater, Puraloop^® addresses two critical challenges: waste management and nutrient supply. This dual benefit exemplifies the power of the circular economy in creating solutions that are both economically viable and environmentally responsible. By recovering phosphorus from wastewater, Puraloop^® not only reduces the environmental footprint of agriculture but also ensures a steady supply of this essential nutrient for farmers worldwide.

A Circular Approach to Sustainable Agriculture

The circular economy model is reshaping industries by emphasizing resource efficiency and waste reduction. Agriculture, traditionally reliant on a linear ″take-make-dispose″ model, is now embracing this shift. Recycling phosphorus is a key component of this transformation, turning waste streams into valuable inputs for agricultural production. By adopting this approach, ICL is helping to build a more sustainable agricultural system that balances productivity with environmental stewardship.

Puraloop^® exemplifies the principles of the circular economy by closing the loop on phosphorus use. Instead of relying on finite phosphate rock, Puraloop^® sources phosphorus from organic waste, keeping resources in use for as long as possible. This not only reduces waste but also enhances the sustainability of farming practices. By integrating phosphorus recycling into the agricultural cycle, ICL is setting a new standard for how we manage essential nutrients in a resource-constrained world.

The Role of Phosphorus in Agriculture

Phosphorus is an indispensable nutrient for plant growth, directly affecting both crop productivity and soil health. As a critical component of energy transfer within plants, phosphorus is essential during periods of high energy demand, such as crop establishment, active root formation, flowering, and fruit set. It plays a vital role in these stages by facilitating efficient nutrient uptake and supporting the overall development of the plant.

Phosphorus contributes to robust root systems, enabling plants to access water and nutrients more effectively, especially in challenging soil conditions. Additionally, it is crucial for processes like photosynthesis, where it is a key element of ATP, the energy molecule that drives plant metabolism. Through the judicious use of phosphate fertilizers, farmers can ensure adequate phosphorus availability, maximize agricultural productivity, and maintain soil fertility.
