Can EVA foam be recycled? The short answer is yes. While Ethylene-Vinyl Acetate (EVA) presents unique challenges due to its cross-linked structure and low density, modern machines voor het recyclen van kunststof have made the process efficient and profitable. For manufacturers and recycling facilities, understanding how to manage EVA waste is key to reducing operational costs and meeting environmental standards.
Understanding Ethylene-Vinyl Acetate (EVA)
EVA (Ethylene-Vinyl Acetate) is a synthetic copolymer known for its rubber-like elasticity and durability. Because it is lightweight, shock-absorbent, and resistant to chemicals, it is a staple material in many industries.
You likely encounter EVA products daily without realizing it. Common applications include:
- Footwear: Shoe soles, slippers, and midsoles.
- Verpakking: Protective foam inserts for electronics and delicate goods.
- Medical: Tubing and flexible medical components.
- Construction & Home: Floor mats, cable insulation, and hot melt adhesives.
- Automobiel: Interior padding and bumper components.
While these properties make EVA excellent for products, they create significant hurdles for waste management. The material is bulky, taking up massive space in warehouses and landfills.
The Challenge: Why EVA Waste Management Matters
The primary difficulty in EVA foam recycling is the volume. EVA foam consists largely of air, meaning a truckload of waste might weigh very little but fill the entire vehicle. This makes transportation inefficient and expensive.
Furthermore, the industrial chain—from granulating and blending to foaming—generates scrap at every stage. Manufacturers are left with cut-offs, rejects, and trimmings that, if not recycled, represent a loss of raw material and revenue.
How the EVA Foam Recycling Process Works
Recycling EVA allows businesses to reclaim this material and reintroduce it into the production cycle. The process typically relies on specialized machinery designed to handle the material’s “springy” nature.
1. Collection and Volume Reduction
The first step is critical: densification. Because loose foam is costly to transport, facilities use an EVA compactor or densifier. These machines use screw compression technology to crush the foam, reducing its volume by a ratio of up to 50:1. This transforms huge piles of light foam into dense, heavy blocks that are easy to stack and ship.
2. Shredding and Grinding
Once collected, the dense EVA blocks (or loose scrap) are fed into a heavy-duty shredder. This machine breaks the material down into smaller, manageable chunks.
3. Granulation and Pelletizing
The shredded material moves to a granulator or pelletizer. Here, the EVA is processed into uniform granules. These recycled EVA pellets can be mixed with virgin resin to create new products. While 100% recycled EVA is sometimes used for lower-grade applications (like fillers), a blend of recycled and new material is common for shoe soles and packaging, maintaining high quality while lowering costs.
