Transforming waste into valuable resources

We’re always looking for new ways to give waste a second life. By putting your waste to good use, you're helping to champion the circular economy and supporting new ways of coping with the increasing scarcity of natural resources and rising materials costs

Separating glass into different colors to optimise recycling

In Belgium, the High 5 company has developed a new way to sort different coloured glass using automation technology. Built in partnership with SUEZ and SIBELCO GREEN SOLUTIONS, the plant is the first in the world sorting incoming flows to separate the four colors needed to make bottles and other hollow glass packaging materials, like pots and jars. The world’s leading supplier of minerals to the glass-making industry, it can produce 250,000 tonnes of recycled glass each year and leads the way in increasing the proportion of recycled glass the industry uses.

A revolution in glass processing

Conventional glass sorting processes separate glass from other waste before processing. High 5’s innovative use of optical sorting technology has transformed the final stages of glass processing, automatically detecting and separating the four colors: clear, green, amber and russet. The technology can also purify and extract residues such as crystal, porcelain or vitro ceramics, which prevent glass from being reused as a raw material.

The resulting quality of recycled glass is exceptional, enabling the plant’s customers to significantly increase the proportion of recycled glass in their production processes, conserve natural mineral resources and energy and limit greenhouse gas emissions.

Delivering new ranges of recycled plastics

In the last 50 years, the use of plastic has increased twenty-fold and certain consumer products contain more than 20 different plastic resins. Using recycled plastics cuts energy consumption by as much as 90 per cent compared to the production of virgin plastic, and we’re committed to increasing the quantity and improving the quality of recycled plastics.

We created Plast’lab® in 2014 in partnership with plastic-consuming industries in order to supply them with a high quality recycled plastics capable of meeting precise specifications.

With Plast'lab®, SUEZ wants to work with manufacturers to build "tailored" solutions in order to supply the recycled plastic that meets their needs.

Creating ‘tailored’ recycled plastics

Recycled plastic creates an economic advantage for manufacturers through enhancing their energy efficiency and environmental performance. However, as a secondary raw material it must meet precise specifications. Plast’lab® analyses, characterises and tests the recycled plastic materials to formulate new ranges of quality plastics that meet the current and future needs of manufacturers in areas such as resistance to heat and impact.

A real alternative to fossil fuels

Dry materials such as mixed plastics, timbers and textiles are a valuable resource, loaded with embedded energy that can be used in the production of alternative fuels.

Transforming waste
SUEZ-ResourceCodiverts more than 95 per cent of waste from landfill.

Our SUEZ-ResourceCo facility is the first of its kind in Australia, converting commercial and industrial waste into fuels that replace gas and coal in power stations and industrial applications. It diverts more than 95 per cent of this waste from landfill, transforming it into more than 75,000 tonnes of Processed Engineered Fuel (PEF) every year.

Better for the environment, better for business

PEF has a significant calorific value and makes an ideal fuel substitute for coal and gas in high-combustion facilities such as power stations and cement kilns. Adelaide Brighton Cement Limited has successfully used our PEF to reduce gas consumption by up to 30 per cent.

Our high-quality PEF benefits customers and the environment in multiple ways, from reduced energy costs and fossil fuel use to a reduction in landfill emissions and the ability to obtain renewable energy certificates.

Rehabilitating contaminated soils

SUEZ Ventia
SUEZ-Ventia Soil Processing Facility creates the potential for re-use.

Our SUEZ-Ventia Soil Processing Facility, opening in 2018, utilises direct thermal desorption treatment and stabilisation technologies to treat a range of contaminated soil to minimise its environmental impact. It’s a world-class solution, offering significant potential to recover valuable resources from contaminated soil and, where possible, create the potential for re-use.

The facility is co-located with our Taylors Road Landfill in Dandenong South – Australia’s only landfill licensed to receive category B solid Prescribed Industrial Waste – to offer a complete resource recovery and management solution for contaminated soils in Victoria.
