Siberian Glass Gets Cleaner as the Economy Goes Circular
Sibsteklo, a glass manufacturer in Novosibirsk, has upgraded its recycled-material processing complex with a new air extraction and dust-removal system.
The sophisticated system can filter up to 21,000 cubic meters of air per hour. It captures 99.9% of airborne particles, keeping production optics from going “blind” while reducing the plant’s environmental impact.
Clearer, Smarter Vision
Earlier this year, optical separators were installed at the company’s recycled-material processing complex. They scan a stream of broken glass, or cullet, identify pieces by color, and separate out ceramics and stones. But the glass plant’s “eyes” are vulnerable to dust. Once fine particles settle on the optics, the smart machinery can no longer reliably tell a green fragment from a brown one. That is where the air extraction system comes in, keeping the entire automated sorting line running consistently.
The new system protects precision equipment from premature failure while creating safer, more comfortable working conditions for employees on the processing line. The equipment is Russian-made. And industrial companies are increasingly choosing domestic machinery that offers a better balance of price and performance than imported alternatives. Building domestic technological capacity and replacing imported equipment used in waste processing are among the government’s industrial policy priorities.
Closing the Loop
The cleaner and more accurately cullet is sorted, the more of it can be used to make new glass. In the first quarter of 2024, the plant increased its use of cullet in production by 46%, conserving more than 16,000 metric tons of natural resources. Sibsteklo is now operating experimentally with recycled content of up to 80%. One metric ton of recycled cullet saves about 1.5 metric tons of virgin mineral raw materials. This approach reduces pressure on quarries, lowers energy consumption during glass melting, and cuts emissions from firing.
The Novosibirsk complex currently has an annual processing capacity of 132,000 metric tons of recycled material. The company plans to increase production to 1 billion containers a year. But the manufacturers themselves say the biggest obstacle remains collecting cullet and transporting it between regions. Russia still needs to build a network of collection sites and waste-sorting plants, gradually creating the infrastructure for a circular economy.
Clean Air, Clear as Glass
The national Ekologiya (Ecology) project is intended to address this challenge. Its main goal is to improve environmental conditions across the country by 2030, including by establishing more effective waste processing. All municipal waste is expected to be sorted, with at least 25% reused.
Russia generates about 5 million metric tons of glass waste each year. Following circular-economy principles, Sibsteklo is contributing to the country’s environmental security by actively developing infrastructure for glass recycling.
Similar facilities are emerging at other plants across Russia. For example, the Simvol glass plant in Vladimir has opened a cullet-processing facility to increase its share of recycled raw materials. The entire production chain, from crushing through sorting, as well as the software, is Russian-made.
Air pollution is also gradually declining. Last year, industrial facilities and transportation emitted 21.2 million metric tons of pollutants into the atmosphere, 881,600 metric tons, or 4%, less than in 2024. Pollution-control systems at individual plants are helping bring national targets closer. At Zavod TEKHNO, a fiberglass manufacturer in Serpukhov, another gas-cleaning unit has been deployed that is expected to raise dust-removal efficiency to 95%–99% and gas-removal efficiency to 80%.
In this way, Russian industry continues to refine its production processes, bringing environmental protection, automation and economic efficiency together in a single system.
