Recycling material replaces
valuable raw materials
During the production of glass products, waste in the form of hot and cold glass always arises. Glass cullet, however, is a valuable secondary raw material for the glass production. It is one of the most important sources for saving raw materials and energy.
To recycle hot liquid waste glass, which can arise in gobs (hot gobs) or as glass strings, an advanced technology is necessary. The goal is to return the waste glass back into the melting process in an ecological and economical way.
We also design, deliver, and construct entire post-consumer glass processing plants according to customer requirements.
This is our contribution towards environmental protection and recovering energy and raw materials.

Scraping conveyors
Glass production always generates a certain amount of glass waste. Scraping conveyors are used to deliver the still hot glass drops or threads back into production. These scraping conveyors are positioned under the molding machine and guarantee hot glass recycling around the clock, 24/7 with minimum deployment of personnel.
Our scraping conveyors are exactly aligned to the requirements of our customers. Their length and design are based on the drop points of the hot glass waste. There is no escaping the fact that scraping conveyors are the
foundation for all automatic factory cullet processing plants.
Exactly what you need:
- Scraper tank in standard steel or stainless-steel design
- Scraping conveyor with bush conveyor chain (double chain execution)
- Scraping conveyor with fork link chain (single chain execution)
- Scraper length and tank width in variable design
- Scraping conveyor with or without double bottom
The features at a glance:
- Low wear due to high quality materials
- Simple installation
- Service and maintenance friendly
- Conveying speed adjustable by Zippe control system
- In-house production at our plant in Wertheim

Scraping Conveyor equipment and water treatment
Falling tubes
Falling tubes convey the arising hot glass into the scraping conveyor. They can be manually orautomatically adjustable, in a fixed execution and/or with vibrating drive.
Gob mangle roller
Very large, heavy hot glass gobs (hot gobs) are sheeted (rolled out) over two rollers to a predetermined glass thickness by means of this roller.
Hereby the glass gobs attain an essentially larger surface and cool down more rapidly. The required distance for cooling and granulating the hot glass in the scraping conveyor is significantly reduced.
Both squeezing rollers submerge into the scraping conveyor´s cooling water whereby the separate cooling of the squeezing rollers is not required.
Water treatment
Fundamentally, all solids which form a sediment over time can be easily and economically separated with the lamella separator. Depending on the density, these are generally solids with a diameter larger than 50 μm.
To separate smaller particles such as impurities, flocculation agents are implemented in order to produce settleable flocs (flocks).

Intelligent scraping
with the ZMART® Scraper Control
At Zippe, we continuously improve our products to ensure that our machines are state-of-the-art.
Two areas of particular concern to glassmakers are reducing wear and minimizing the portion of fine material in scraping conveyors. For this reason Zippe developed the innovative ZMART® Scraper Control System.
Depending on the gob weight and quantity of gobs or hot bottles, this advanced control system module decides whether and at which speed the scraping conveyor operates.
Furthermore, the required operating time is calculated individually and minimized. Standardized interfaces between the IS machines and the scraping conveyor control system supply the production data automatically. If required, these parameters can be entered and adapted manually via touch panel and thus allow a continuous and individual optimization
of the process.
In this way high operational flexibility is achieved, the operation time is reduced to a minimum and, above all, this cost-saving alternative is permanently available.
The ZMART® Scraper Control System has already been successfully commissioned and is fully functional.
The features at a glance
- reduction of wear, extending the lifespan
- minimization of fine cullet portion
- lower maintenance
- considerably lower energy consumption
- cost saving and CO2 reduction

Crushers – custom made
Zippe BRV™ hammer crusher
The BRV™ crusher for crushing container glass, tableware and float glass is robust and reliable and is therefore ideally suited to the harsh operational conditions in a glass plant.
The impact hammers and impact plates are made of high-quality electric steel casting which has proven to be excellent for crushing glass.
The material abrasion is so minimal that it has no effect on highly sensitive glass. The crusher casing is easily opened to quickly replace impact hammers and impact plates.
It is driven by a V-belt drive with a three-phase motor.
The features at a glance
- Long lifespan
- Adjustable grain sizes
- Simple installation
- Service and maintenance friendly
- Low-vibration, therefore no complex foundations required
- Manufactured in-house

Crushers for float glass
During the production of float glass, waste, in the form of glass plates and border stripes (edges), continuously accumulates in the cutting line area. This waste must be disposed of automatically without disrupting the glass production process. We have developed special Zippe crushers for various crushing requirements.
Lowerable emergency plate crushers have extractable crushing tools and is placed above the roller conveyor over the glass ribbon. In the event of malfunctions on the cutting line, etc., the entire production must be disposed of for a short time. The continuously fedd glass is crushed and the cullet transferred to the basement area.
Inline plate crushers are installed underneath the roller track. Defective plates are automatically conveyed out of the production line and transferred into a plate crusher by means of a diverter.
Edges, created by cutting the plates, are fed to the edge crusher by means of a cullet hopper. If no sufficient cellar or cullet canal exist, an edge crusher can be placed on both the left and the right side of the production line.
For further processing, the pre-crushed pieces of float glass are flexibly and reliably crushed to the grain size required for the melting process by a hammer impact crusher.
