Offer Extents

The offer includes a complete recycling plant, designed for the processing of PET-bottles

from post-consumer collection that are pre-selected and compacted to bales or

briquettes. The final products after processing are cleansed, separated, and ready-to-sell

PET-flakes and PO-fractions, both packaged in Big-Bags

1 Technical Process Description

1.1 Material Introduction

The PET-bottles that are initially compacted in the shape of bales or briquettes are

introduced into the bale breaker with the help of a forklift after prior removal of the

packaging wire. Inside the bale breaker, the bottles are untangled and fall into the

discharging screw that transports the bottles evenly to the elevating conveyor belt. By

means of regulation of the rotational speed of the screw, the plant throughput capacity

is determined. The elevating conveyor belt is equipped with a non-magnetic area that

has a permanent magnet installed above it. Ferromagnetic materials that are present

within the input are thereby removed from the plastics. The elevating conveyor belt

moves the remaining materials to the manual sorting stage.

1.2 Manual Sorting Stage

The sorting belt is located on top of a stage structure that is designed to incorporate four

manual sorting stations. This stage is mounted in a way that large sorting containers

can be located below where the selected materials are introduced manually through

shoots. A wide-area detection coil is mounted below the sorting belt and stops the

transport if any metallic materials are detected within the stream. The selection

personal is thereby given the opportunity to remove such materials manually and restart

the belt once this is done. The time-lapse due to stopping and restarting of the sorting

belt is then compensated for by a dispensing bunker. Evenly a screw conveyor

introduces the pre-selected materials into the mill funnel.

1.3 Cutting and Pre-Cleaning

The cutting mill is essentially a wet-shredding and cutting mill. With the help of adding

an abundant amount of water, the shredding process in this stage provides a

combination of cutting and cleaning effects. The machine interior is covered with a

highly wear-resistant material (Hardox). This interior shielding, along with the stator

blade covers, is completely replaceable. During the shredding process, 95% of all paper

labels are dissolved. Inside the frictional cleaner unit, the washing water along with the

therein contained paper and dirt is separated from the material to be processed and

pumped to the fibre-separator of the circulation container #1. The material is

transported towards the air-stream separator #1 with the help of a blower unit.

…/4

 

Page 4 to Quotation E 644

1.4 Air-Stream Separation Stage

Within the vertical air-stream separator, the PET- and PO-flakes are separated

From other materials contained in the mill output like labels, paper, and dust.

The material transport into the air-stream separator is done through a cyclone

with a rotary valve. The heavier PET- and PO-flakes descend to the bottom and

are transported by another blower through the cyclone of the separation stage.

The lightweight particles inside the air-stream are vacuumed off the top of the

vertical air-stream separator and introduced into the cyclone for waste.

The separation resolution can be adjusted via the label blower setting.

1.5 Separation Stage

The separation stage consists of a stirring and a separation container.

The material transport into the stirring container is passed through a

cyclone with a rotary valve. With the help of a stirring mechanism,

the plastic material is blended into the aqueous separation medium.

A pump transports the homogenous mixture into the separation

container where due to a laminar flow, the heavier particles move towards the

bottom and the lighter particles towards the top of the flow. The

principle behind this separation mechanism is the difference in

density of the materials to be separated. While PET has a higher

density than water and therefore sinks to the bottom of the cont.

other polyolefin plastics like PP, PE, etc. and other less dense

materials (with respect to water) float on top of the medium.

The materials that are skimmed off the top of the stream are

introduced into a frictional cleaner unit and then transported via

blower to the PO filling station, whereas the heavier PET from

the bottom is also introduced into a frictional cleaner unit but

then transported to the next stage. With the help of the

frictional cleaner units, the materials are separated from the

washing medium and the dirt enriched medium pumped into

the fibre separator of the washing medium circulatory system #2.

1.6 Hot Washing Stage

The hot washing stage utilizes a 4-5% caustic soda solution as

washing medium. In order to maximize the cleaning effect of this

stage, the washer units are heated by electrical heater plates.

The temperature of the washing medium and its caustic soda

concentration is automatically regulated by programmable active

feedback control systems. Through a cyclone with a rotary valve,

the PET-flakes are introduced into the heated screw washer unit

wherein the material is transported through parallel running,

low revolution screws. The extended processing time within this

unit provides a maximum cleaning effect (separation and dissolving

of adhesives and dirt). After the screw washer, the material is

introduced into a heated turbo washer unit where it is intensively

cleaned with the help of strong turbulences generated by the

beater wheels contained. The frictional cleaner unit that is

installed behind the turbo washer unit then separates the

washing medium from the PET-flakes and removes remaining

adhesives. The washing medium that is removed by the frictional

cleaner unit is introduced into the fibre separator of the circulatory

system #4. A blower unit transports the mostly dry flakes into the

post-washer unit.

…/5

 

Page 5 to Quotation E 644

1.7 Post-Washing Stage

Within the post-washing stage, the material is intensively cleaned

from remaining caustic medium utilizing strong turbulences

generated by the beater wheels contained. Introduction is done

past a cyclone with a rotary valve. Via the washer overflow, the

material is introduced into a twin frictional cleaner unit where it

is mostly separated from the washing water within the first stage

and dried within the second stage. The dried PET-flakes are then

blown into the PET-Flake Post-Processing and the washing

medium pumped into the circulatory system #3.

1.8 PET-Flake Post-Processing

The first stage of the post-processing is composed of a vibrating

channel and a drum type magnet. The vibrating channel consists

of two layers where the upper one is responsible for straining the

oversize flakes and the lower one for spatially separating the

flakes prior to magnetizing and separating remaining ferromagnetic

materials. The grain type PET falls into another channel

where its flow is further spaced out and introduced into a

combinatory separator. This not only separates the PET from

non ferromagnetic materials like stainless steel or aluminium,

but also post-separates by color which minimizes errors that

occurred in the manual selection stage. Smaller amounts of

PET-flakes are also blown into the waste collector by the

Combinatory separator. The clean material then falls into a

blower funnel and is transported to the filling station for PET.

1.9 PET Filling Station

The filling station consists of a structure designed to hold two

Big-Bags at the same time. Above it, a dispensing and storage

container is mounted that has a selective dual output spout

aiming into a Big-Bag each. Sensors mounted to the storage

container above control the level inside. Inside each filling

funnel, sensors are mounted to control the filling level of the

bags. Once a bag is full, the dual funnel switches to fill the

other bag mounted which assures a continuous filling

operation. Additionally, the filling station contains a pneumatic

vibrator unit, which maximizes the filling capacity of each

Big-Bag by minimizing air gaps.

1.10 PO Filling Station

This station consists of a cyclone, a storage funnel, a rotary

valve, and an operational stage with bag mount. Inside the

filling funnel, a sensor is mounted that stops the rotary

valve, once a Big-Bag is full. The operator then replaces

the full Big-Bag with an empty one and restarts the filling

process. Meanwhile this is done, the storage funnel

compensates for the stopped material flow without overflowing.

The circulatory pumps move the cleaned water from the circulatory containers to the

specific plant components (see layout).

The dirty water separated by the frictional cleaner units is pumped onto the specific

fibre separators before it is re-introduced into the circulatory systems. The foreign

materials (dirt, fibre, adhesive chunks, etc.) are strained off and introduced into a waste

press. Some of the water (approx. 1.5 – 2.5 cubic meters per hour) are taken out of the

circulatory systems of the mill and separator systems and have to be treated by a water

treatment unit before re-introduced into the specific circulatory system. It is strongly

recommended to feed fresh water to the post-washing stage (2 – 3 cubic meters per

hour) and the circulatory container #4.
