HERBOLD MECKESHEIM: Bottle-to-bottle Flakes with FDA Approval Now Also in Honduras

Сase studies

In Honduras the collection rate of PET bottles amounts to 84 %, nevertheless, bottles have to be imported in order to use the plant to full capacity. 2000 t PET bottles per month are treated with the plant technology from Herbold Meckesheim.

In a multi-stage process, the bottles are pre-sorted, size-reduced, washed cold and hot and after drying forwarded to a flake sorting step. The German machine manufacturer HERBOLD MECKESHEIM produced, installed and commissioned the plant.

After sorting, the PET bottles are size reduced in two Herbold granulators with a capacity of 1800 kg/h.

The hot washing plant for PET bottle flakes from Herbold Meckesheim guarantees high-quality regranulate at INVEMA.

In a second step a plant was installed for treating the polyolefine fraction from the recycling process, i.e. the caps and labels of bottles.

After regranulation the end product is sold to the local Coca Cola bottle producer. The owner of INVEMA, George Gatlin, states in an interview: "Coca Cola is enthusiastic about the quality of the regranulate that we produce."

INVEMA Group has 370 employees in Honduras and further 100 in El Salvador. They see to the collection, reception, sorting and treatment of the bottles. A second expansion step is in preparation. Its aim is to produce thermoforming PET film suitable for use in foodstuffs.

Part of the energy needed for the recycling plants is produced on site: with 3.640 solar panels on the roofs of the plant location they are generating 1 MW electrical power.
