Redner’s Markets, Giorgio Fresh Co. and Modern Soils have formed a closed‑loop partnership that transforms byproducts from mushroom cultivation into premium soil products sold at Redner’s locations.
“This is more than a sustainability initiative – it is a blueprint for the future of regenerative agriculture and responsible manufacturing,” said CJ Ciarrocchi, CEO and president of Modern Soils.
“By converting spent mushroom substrate into premium soil products, we are extending the life cycle of a valuable natural resource and creating meaningful environmental impact.”
The collaboration creates a circular ecosystem: Giorgio grows mushrooms using nutrient‑rich substrate, distributes them through Redner’s, then Modern Soils converts the spent substrate into potting mixes and soil products. Those products are sold at Redner’s under the Giorgio Mushroom Soil brand, and customers use them in gardens and landscaping, returning nutrients to the soil.
“Extending the value of our resources and regenerating the natural world are core tenets of a sustainable production system,” said Mark Currie, CEO of Giorgi Companies.
“This partnership demonstrates what is possible when industry leaders align around innovation and long‑term stewardship. Together with Redner’s Markets and Modern Soils, we have created a scalable model that transforms agricultural byproducts into valuable consumer products while strengthening the connection between food production and environmental responsibility.”
