How Freeze Drying Helps Reduce Food Waste on a Large Scale
By Parker Freeze Dry
Food waste is a global challenge—one that affects the environment, economy, and food security. Each year, nearly 1.3 billion tons of food are wasted worldwide, much of it lost during distribution or due to spoilage. At Parker Freeze Dry, we believe industrial-scale freeze drying plays a pivotal role in reducing that waste and transforming how businesses preserve food at scale.
In traditional supply chains, food often spoils before it ever reaches the consumer. Perishables like fruits, vegetables, meats, and dairy products have short shelf lives and are vulnerable to transportation delays, temperature changes, and overproduction.
Freeze drying removes moisture from food without compromising its nutritional value, texture, or flavor. By freezing the product and applying a vacuum to sublimate the ice directly into vapor, we preserve the integrity of the food while extending its shelf life—often by years instead of days or months.
Longer Shelf Life: Products last significantly longer without refrigeration or preservatives, reducing spoilage and extending market reach.
Saves “Imperfect” Produce: Fruits and vegetables that don’t meet fresh-market cosmetic standards can be freeze dried and sold—keeping them out of landfills.
Reduces Overstock Waste: Brands can freeze dry excess seasonal harvests (think Apple orchards) or production runs, storing them for later sale instead of dumping unsold inventory.
Lighter Transportation Footprint: With moisture removed, freeze-dried products are lighter, reducing shipping costs and emissions while supporting global distribution.
The freeze-dried pet food market is one of the fastest-growing sectors—and a powerful tool in the fight against food waste. Pet food producers can repurpose high-quality meats, organ cuts, and trimmings that would otherwise go unused in the human food supply. Instead of going to waste, these nutrient-rich ingredients are transformed into premium freeze-dried treats and meals that are shelf-stable, palatable, and biologically appropriate for pets.
By utilizing the full animal and capturing excess from meat processors, freeze-dried pet food manufacturers help close the loop between food production and consumption. With Parker Freeze Dry systems, brands are able to scale up this sustainable model—turning byproducts into profit while meeting growing demand for clean-label, high-protein pet products.
At Parker Freeze Dry, we work with commercial food producers to scale their freeze drying operations efficiently and reliably. From R&D through full production, our systems allow companies to preserve large volumes of food—converting what might have been waste into long-lasting, high-value products.
Whether it's repurposing surplus ingredients, stabilizing supply chains, or extending the life of premium pet food, Parker Freeze Dry systems are helping businesses meet sustainability goals while reducing food waste at the source.
