Manufacturers of glass containers are ready for a multiple increase in the share of glass waste in the composition of raw materials

This was stated by Sergey Lukyantsev, Development Director of Siberian Glass LLC, Deputy Chairman of the Ecology Committee of the Association StekloSouz of Russia, speaking at the session “The Market of Secondary Material Resources and Prospects for Recycling in Russia”, which was held as part of the business program of the International Forum on Waste Management , environmental technologies and renewable energy "WasteTech", which took place in Moscow with the support of the Ministry of Natural Resources and Environment of the Russian Federation, the Ministry of Industry and Trade of the Russian Federation, the Ministry of Construction and Housing and Utilities of the Russian Federation.

- The melting temperature of sand is 1,400-1,450 ° C, and the glass waste required for the production of new glass is lower - 1,100-1200 ° C, since the most energy-consuming stages of glass-making in this case have already been passed. It is possible to recycle glass without losing its physical and chemical properties endlessly, thus, the material is unique for a closed-cycle economy, ”reminded Sergey Lukyantsev, substantiating the economic and environmental feasibility of recycling cullet.

According to him, today Russian glass container enterprises use from 10 to 25% of cullet in the composition of glass raw materials. Moreover, in European plants this figure exceeds 60%, and in Japan it reaches 90%. In order to return more glass waste into circulation, it is necessary, first of all, to create an effective collection system from citizens, as well as to ensure the sampling of glass fractions from the mixed MSW stream.

- Installation of containers for the selective accumulation of MSW, as an option, special containers for glass, could stimulate households to separate waste. No less important is an active environmental education work on the part of the state, first of all, with the help of state TV channels, which set a trend for the formation of a culture of responsible consumption for all popular information resources, - said Sergey Lukyantsev, noting that Sibsteklo places bins for sorting MSW, cooperates with the HoReCa sector, opens points of reception of secondary resources from the population, conducts excursions in glass complexes for eco-activists.

According to Sergey Lukyantsev, cullet intended for recycling in the manufacture of glass containers must be processed - cleaned of contaminants and impurities, fractionated, sorted by color, etc .:

- The current possibilities for the preparation of glass waste allow our specialists to successfully use them in a ratio of 50 to 50 with a batch. As the experience of foreign factories shows, during optical sorting of cullet its share is increased to 70-80%. With an increase in this value, the requirements for the purity and homogeneity of the chemical composition of recyclable materials increase significantly.

According to the expert, due to the geographic extent of Russia, the state should subsidize part of the costs of delivering sorted waste to processing and disposal sites.

- One of the mechanisms of state support will be implemented through the introduction of extended producer responsibility, - he emphasized. - In "StekloSouz", which includes "Sibsteklo", they believe that the legislative decisions currently being considered should help to attract glaziers to direct participation in the process of handling glass waste.
