Innovtion at the Heart of SITA, a Subsidiary of SUEZ ENVIRONNEMENT, Is Making Progress in Europe: In Antwerp, Belgium, a new glass recycling plant is capable of making four different colours of glass

Today, Christophe Cros, SUEZ ENVIRONNEMENT’s Deputy Chief Executive Officer in charge of Waste Europe, introduces High5’s new glass sorting and recovery facilities in the heart of the port of Antwerp.  This plant is a crucible of cutting-edge optical sorting technology for glass recycling.

High5 is the product of an industrial partnership between SITA, the European leader in waste recovery, and Sibelco, world leader in the supply of minerals to the glass industry.

The High5 plant can recycle 250,000 tonnes of glass per year, and is the first plant in the world to separate the incoming flows into 4 different grades. An initial manual sort, which separates the glass from other waste (such as metallic foils, plastic, etc.), is followed by the more traditional stages of extracting and removing the ferrous and non-ferrous metals from within the raw glass by “air-scouring” and “suction”, but the technological innovation comes to light in the final processing stage.

This involves passing the coloured raw glass through a bank of latest-generation optical sorters. The flow is sorted into four colours: white, green, amber and russet. The machines can also purify and extract residual crystal, porcelain and ceramics, which are detrimental to reusing the glass as a raw material.

The unique quality of the cullet produced by High5 means that the plant’s glass-maker customers will increase considerably the proportion of recycled glass used in their own production, thus preserving natural mineral resources. This switch will also save energy and limit greenhouse gas emissions.

The size of this facility, as well as the fact that is accessible by sea and above all, the quality of the products it produces, all combine to make this plant unique in Europe. It provides a perfect response to the increasingly specific needs of the glass industry.

Christophe Cros, Deputy Chief Executive Officer of SUEZ ENVIRONNEMENT in charge of Waste Europe, explains: “We are proud to unveil this ultra-modern facility for glass recovery, which is the first of its kind in Europe. This sorting centre is an example of one of the main challenges of the circular economy: the recovery of waste and the production of secondary raw materials.”

SUEZ ENVIRONNEMENT is continuing to develop its waste recovery activities, one of its 4 strategic priorities, and is consolidating its position as an industry leader in Belgium. As a result of its industrial partnership with Sibelco Green Solutions, SITA is active in the recycled glass sector in this country with 2 plants; High5 in the port of Antwerp and Minérale in Charleroi, and processes 370,000 tonnes of glass annually.
