Turning Waste into Value: Screw Press for Fruit and Vegetable Processing

JX Filtration May 6, 2025 Screw Press

In the agricultural and food processing industries, managing organic waste effectively is a growing concern. Every day, tons of fruit and vegetable waste are generated — often discarded, underutilized, or difficult to transport due to high moisture content. Fortunately, with the help of modern equipment like the screw press, this organic waste can now be transformed into valuable resources for farms.

A screw press, also known as a dewatering screw machine, is designed to handle high-moisture materials such as discarded fruits and vegetables. The machine combines crushing and pressing in one process, efficiently separating liquids from solids. After pressing, the moisture content in the material is reduced to about 50-60%, making it much easier to handle, store, and repurpose.

One of the most promising applications of this pressed material is in animal husbandry and insect farming. The fibrous, semi-dry pulp remaining after dewatering is rich in fiber and nutrients, making it an excellent feed material — especially for Black Soldier Fly (BSF) larvae, pigs, and poultry. Farms that adopt this process not only reduce their waste disposal costs but also produce low-cost, sustainable feed.

What makes this solution especially attractive is its simplicity and energy efficiency. With no need for chemical additives, the screw press can continuously operate and be customized to different feedstocks and capacities — ranging from 800 kg/h to several tons per hour.

As global demand for sustainable farming practices grows, repurposing organic waste with screw press technology is a smart investment. It not only helps reduce environmental impact but also turns waste into profit — a win-win for food processors and farms alike.
