ENERPAT recently conducted an on-site technical consultation for a packaging manufacturer in Irapuato, Guanajuato, Mexico, to evaluate a plastic waste recycling solution for PET-G resin blocks and production offcuts.
The customer operates a large manufacturing facility producing shrink sleeve labels and packaging materials. During production, reusable PET-G resin blocks and edge trim are generated. Instead of disposing of these materials and losing recoverable value, the customer is exploring an in-house recycling process to return the material to production.
On-Site Recycling Challenge
The customer currently generates approximately 500 kg of PET-G waste per day.
The recyclable material is stored in stainless steel containers, with individual pieces reaching up to approximately 1,340 × 830 mm and a maximum loading weight of around 150 kg.
Because the material comes directly from the production process, it can also be at a relatively high temperature when collected.
The customer's target is to reduce these large PET-G blocks to less than 25 mm before feeding them into the existing downstream size-reduction equipment to produce reusable plastic feedstock.
This creates several key technical considerations:
Large and irregular PET-G blocks require effective pre-shredding.
The target particle size is below 25 mm.
The material temperature immediately after production must be considered.
The available installation area is approximately 2.5 m wide.
The shredded material needs to be transferred into the customer's existing feeding system.
The customer's existing feed inlet measures approximately 1,400 × 540 mm.
· The internal twin-roll structure of the existing feeder may affect material flow and create a potential blockage risk.
ENERPAT On-Site Equipment Assessment
During the visit, ENERPAT's technical team evaluated the customer's material, production conditions, installation space and existing equipment.
Based on the initial requirements, an F800 Single Shaft Shredder is being considered as the primary pre-shredding solution.
The F800 Single Shaft Shredder would be responsible for reducing the large PET-G blocks into a more manageable size before the material enters the customer's existing processing system.
A key technical point is whether the F800 can achieve the customer's required 25 mm output size with a suitable screen configuration. ENERPAT will further verify the feasibility of using a 25 mm screen for this application.
Feeding & Material Transfer Considerations
Material feeding is another important part of the proposed solution.
The customer currently has only one available feeding point, with an opening of approximately 1,400 × 540 mm. However, the internal twin-roll structure may restrict the entry of larger shredded pieces.
ENERPAT is therefore evaluating two potential feeding methods:
Option 1: Forklift Feeding
A forklift could be used to rotate and feed the stainless-steel container or large PET-G blocks into the pre-shredder.
Option 2: Conveyor Feeding
A conveyor system could be integrated between the pre-shredder and the customer's existing feeding equipment to provide a more controlled material flow.
The final configuration will depend on the verified discharge size, feeding height, available installation space and the structure of the customer's existing equipment.
From Pre-Shredding to Plastic Recycling
The customer's long-term objective is not simply to reduce waste size, but to recover PET-G production scrap and return it to the manufacturing process.
The proposed recycling route therefore focuses on integrating the Single Shaft Shredder with the customer's existing size-reduction equipment. Where further processing is required, a Plastic Pelletizing Machine can also be considered as part of a future recycling solution to convert processed plastic waste into reusable pellets.
This modular approach allows the customer to begin with the required pre-shredding stage and further develop the recycling process according to actual production requirements.
ENERPAT's Next Technical Steps
Following the on-site assessment, ENERPAT's engineering team will further evaluate:
1. F800 Single Shaft Shredder with a 25 mm screen and whether it can meet the required output size.
2. Discharge and transfer design between the pre-shredder and the customer's existing 1,400 × 540 mm feeding system.
3. Potential material blockage risks caused by the existing twin-roll feeding structure.
4. The most suitable forklift or conveyor feeding solution.
5. The overall equipment layout and available installation space.
6. A follow-up on-site technical consultation to confirm the final recycling solution.
ENERPAT will continue working with the customer to develop a practical PET-G recycling solution that fits the existing production line, available space and material handling requirements.
