Recycling of glass waste in a glass bottle plant


Increase and upgrade of the glass waste recycling capacity for the production of glass bottles. Approximately 40,000 tonnes of different glass waste is generated annually in Estonia. Most of the glass waste is landfilled or downcycled to low quality products (concrete products, filling material, etc.). Only a small amount of glass waste is used to produce glass bottles. The Bottle and Glass factory is the only glass-bottle manufacturer in the region (in the Baltic States) that is able to recycle most of the glass waste collected in the region.

The aim of the planned project is to increase and upgrade the glass waste recycling capacity for the production of glass bottles. The technical goals of the project are to assist the Bottle and Glass plant to solve the following problems they are facing today:

1.To replace technologically aged crushing systems that no longer ensure the necessary quality of the product resulting in a rising amount of waste;
2.To replace the current furnace to allow sufficient use of glass waste as a raw material;
3.To reduce unreasonably high energy consumption/costs.

Expected outcome:

The environmental goal for the project is to reduce the amount of glass waste created during the production process at the plant, to increase the amount of glass waste used as a raw material in making glass bottles at the plant (ca. 10,000 MT of glass cullet gets recycled p.a.), to reduce energy consumption by 38% and to reduce its CO 2 footprint by 25% (amount of CO 2 released per year).
