The Roller / Disc Screen is a high-performance, heavy-duty screening solution specifically designed for plastic recycling lines. Featuring multiple rotating shafts equipped with cast-steel or coated discs, this equipment excels at precise size-based separation, making it a vital pre-sorting unit for modern PET, HDPE, PP, and mixed plastic recycling systems.

Amstar introduces a reliable, space-saving solution for recycling bulky EPS  materials with our EPS Hot Melting Machinery series. These machines transform foam waste into dense ingots, reducing volume by up to 90%, easing storage and transportation, and enabling eco-friendly reuse.

The Sludge Dewatering Machine, also known as the Screw Press Sludge Dewatering Machine, is an advanced solid-liquid separation equipment widely used in municipal wastewater treatment and various industrial applications.

We’re excited to showcase our twin shaft plastic shredder, a powerhouse machine designed for demanding plastic waste reduction tasks.

Purpose-built for recycling facilities and plastic processing operations, this machine is ideal for handling a wide range of plastic waste, including films, bags, pipes, and solid chunks.

In the ever-evolving world of plastic recycling, drying efficiency is critical. Excess moisture in plastic flakes can lead to lower pellet quality, increased energy consumption, and equipment wear.

In the plastic recycling process, drying is a crucial step that directly affects the efficiency and quality of downstream processes such as pelletizing and extrusion.

This guide outlines the detailed steps for replacing the rotary and static blades, ensuring safe and effective replacement with minimal downtime.

From March 24 to 26, 2025, Amstar proudly participated in the Plastics Recycling Conference (PRC) at the Gaylord National Resort & Convention Center in National Harbor, Maryland.

Amstar’s Laser Filter System is designed to address one of the most critical challenges in plastic recycling: the efficient removal of solid industrial contaminants such as wood chips, paper fibers, stones, metal flakes, and other non-melting residues.
