NEWS > Focus Group for New Nursery Leachate Recycling System

As part of its work to help develop the new European-funded Cleanleach leachate purification system, Salix is calling for 10 nursery managers to attend its Focus Group event at its Croxton Park Nursery in the Thetford Forest, 5-7pm on Tuesday 7 July.

The Cleanleach system, which has been developed in Spain by IRTA, allows nurseries to treat and then recycle the leachates from their irrigation systems, making container plant production more sustainable.

Container plant production facilitates the agronomic management, transport and transplanting of plants used in gardening, landscaping and reforestation, but it also generates leachates that cannot be released into the environment because they contain high concentrates of nitrates and sometimes phosphates.

Cleanleach makes it possible to return these leachates into the irrigation system and take advantage of their nitrate and phosphate content as fertilizers.

The new technology combines slow horizontal sand filtering of leachates under the container area with constructed wetlands to transform the nitrates into nitrogen gas and render the phosphates less soluble.

Last year, Salix constructed the UK’s first demonstration project for the Cleanleach sytem at its wetland and wildflower plant nursery in Norfolk and, on behalf of IRTA, is looking for feedback on the new system from UK nursery managers and growers.

David Holland, Technical Director for Salix, explains: “In Europe, nurseries growing plants used in gardening, landscaping and reforestation take up over 127,000 hectares.

“The new Cleanleach natural treatment process offers a more sustainable alternative to traditional leachate management methods, making it possible to re-circulate the nutrients and irrigation water, and generating significant environmental improvements for the industry.

“We are holding a Cleanleach Focus Group event to gather vital feedback from UK nursery managers and growers about water quality issues, the pros and cons of the new system and how it could improve the sustainability of their businesses.”

The event will be hosted by Salix’s Technical Director David Holland and Albert Sorolla, Technical Director of Spanish project partner Naturalea.  Salix will pay the travel expenses of delegates and provide refreshments.
