UPDATE ON JIZZAX PRODUCTION PLANT: INSTALLATION OF SILO AND CONVEYOR SYSTEM IS IN FULL SWING
The silo and conveyor system is a system for storing, conveying and dosing the mineral input materials as well as for charging the melting furnace. Therefore, it is inevitable for commissioning of the plant. The installation work in this area is progressing rapidly. Three silo containers, metal constructions including stairs and a conveyor belt system for transporting the feed material from the silo system to the melting furnace have already been installed. Our on-site specialists coordinate the construction activities.
EQUIPMENT INSTALLATION HAS STARTED IN JIZZAX PRODUCTION PLANT
After completion of construction works and connection of the facility to power grid in January 2022, the installation of equipment is in full swing.
Our on-site specialists supervise equipment installation and coordinate the technical staff.
The assembly of the melting and fiberization unit has already been completed, and the first test mode melting can begin.
Read more about the progress of the project in our next post.
Valorize, Don’t Landfill !
Construction and demolition (C&D) works inevitably involve large volumes of waste from man-made mineral fibers (MMMF), such as glass and rock wool.
In Austria, MMMF products that have been manufactured by a member of the Austrian Association of Mineral Wool Industry since 1998 are not considered dangerous.
In the case of demolition and renovation works, the required documentation of non-hazardousness (manufacturer’s proof with product safety data sheets, invoices, reference to goods seal, hazard evaluation by means of chemical analysis) is not feasible. Therefore, to this day, all MMMF waste is classified as hazardous and landfilled under the appropriate key numbers for hazardous waste.
The landfilling of MMMF waste is associated with a relatively high consumption of landfill capacity. Any landfill operator can attest that the low density of this waste stream, even after compaction in a baler, requires a special, more laborious process.
With the recent amendment of the Landfill Ordinance of 2008, a landfill ban for MMMF waste is planned in Austria from January 1st, 2027.
The binding Austrian regulation “Artificial mineral fiber waste – MMMF waste from the construction site” published in 2019 states: “Material valorization of the MMMF waste is permitted if the treatment ensures that the products produced do not have any hazardous properties. There are currently no known suitable valorization processes for MMMF waste in Austria”.
The legal regulations mentioned, the state of the art that is not up to date, as well as a large number of research projects send a clear message: There is an urgent need for a technology that not only eliminates the hazardous properties of MMMF waste, but also economically converts it into a value-added product.
The focus of our company lies on the development of technologies in which mineral input materials are melted in an inductively heated inline furnace. For C&D MMMF waste, we consider our innovation to be market-ready. We offer companies in the waste processing & valorization sector an opportunity to develop products or substitute raw materials based on inductive melting technology by valorizing C&D MMMF waste.
The simplest solution, as an intermediate step, to landfill melted, inert and significantly volume-reduced (more than 50-fold) MMMF waste, can be implemented promptly with the technology we have developed.

Two types of products from mineral wool waste
Using induction inline melting, we have obtained two types of products from mineral wool waste: glassy granulate (product of amorphous structure) and crystal structure castings (including shaped ones).
Such processing of mineral wool waste makes it possible to reduce the volume of waste by more than 50 times, which is a significant advantage for disposal. In addition, mineral wool waste loses its hazardous (carcinogenic) properties due to the transformation of fibers into granules or stones, which allows further use of waste in various industries.
Any mineral material with a fraction of 0 to 10 mm and a moisture content of up to 20% can be used for processing. A mixture of components that differ greatly in density and melting point is also possible.

The construction work on the erection of plant building is currently nearing completion. The installation of equipment will begin in the near future, followed by a trial run.
The plant with a capacity of 25,000 t of mineral wool p/a is scheduled to go into operation in 2022.
Process of recovery of metals, developed by IB Engineering
Our company has developed a process IBEmr for the recovery of valuable metals from metal-containing waste.
Thanks to the new IBEmr technology, customers can not only reduce the transport and disposal costs when disposing of metal-containing waste, but also generate additional profit from recovered valuable metals.
You can find out more about the IBEmr process in our publication https://www.ibe.at/wp-content/uploads/2021/09/Artikel-potenzial-induktives-schmelzen_en_08_09_2021.htm.
Waste inertization process developed by IB Engineering
Companies of different industries face the same issues while recycling industrial waste:
- high costs for transport and landfilling,
- strict environmental standards for waste disposal and, as a result, a failure to dispose of waste in its original form.
The IBEwi inertization process patented by our company is not only a reliable method to prevent the leaching out of toxic substances, but also a tool that allows to significantly reduce the volume of waste.
You can find out more about the waste inertization technology IBEwi in our publications:

PLATINUM-FREE bushing plates – THE FUTURE OF CONTINUOUS FIBERS MANUFACTURING
One of the key operations in the production of continuous mineral fibers is their pulling out of the melt through bushing plates. The following requirements are imposed on the bushing plate material: operating temperature up to 1500 °C, no interaction with mineral melt, resistance to oxidation in air, high thermal conductivity and heat resistance, as well as resistance to thermal shock. Bushing plates are usually made of platinum-rhodium alloys.
Our company has developed an alternative to platinum-rhodium bushing plates, which allow to reduce the cost of bushing plates tenfold. The bushing plates of IB Engineering meet all the above requirements.

A NEW TECHNOLOGY FOR INDUCTIVE MELTING OF GLASS
Our company has developed a unique technology of INDUCTION GLASS MELTING, that significantly increase efficiency and environmental friendliness of the technological process. The new glass melting technology can considerably reduce a glass melting time, achieve a homogeneity of the melt and minimize emissions of pollutants into the atmosphere. The technical equipment for inductive glass melting is compact and easy to use.
Unlike other methods of glass melting in electric furnaces, this process does not require any special starting processes or intensive water cooling (such as, for example, with the “Skull Melting” technology / Cold Crucible Glass Melting).

LINE IBE13R
One of the most pressing topics in the production of mineral wool is the recycling of waste and off-grade raw materials .
During the production process, several groups of waste are generated. They can be initially categorized into resinous waste and non-resinous waste.
The first group includes such waste as “shots” from the centrifuge, strip edge trimmings, and rejects. The second group includes mainly fine fractions of raw materials and basalt dust.
Regardless of the group, the waste cannot be used for remelting in the same form in which it was collected.It must either be briquetted, which is a quite costly and ineffective method, or crushed into dust and further processed using the IBE smelter.
In our technology, the waste of both groups is physically separated, being in different bunkers, and mixed in a pre-set proportion before being fed to the melting unit.
Subsequently the melt can be used in the same way on the existing line, or – which is considered the most optimal solution – on a separate line IBE13R with a capacity of 8,000 or 16,000 tons of product p.a.
This line is compact and economical, and the cost of production of boards on it does not exceed 2/3 of the cost of production from primary raw materials.
Thus, the IBE13R line not only allows to avoid waste disposal costs, but the production of the same product turns out to be no less than 1/3 cheaper than production from primary raw materials.
The average cost of producing standard boards from the a.m. waste for the European region is 160-180 €/t.
- The main technical data of the IBE13R line are given below:
- production area – 1,000 m2
- energy consumption – 0.8 MWh per 1 t of product
- the need for service personnel is 5-6 people per shift
- boards width – 1.300 mm
- boards thickness – from 20 mm to 400 mm
- recommended capacity – 8,000 tons p.a. (with the possibility of expanding up to 16,000 tons p.a.).
