A player in economic development

Over the years, SPAQUE has become a major player in the economy of Wallonia. For 30 years, it has contributed to the activity of many companies that have worked on the brownfield sites and landfills it rehabilitates.

These companies come from sectors as diverse as civil engineering, waste management, research, consultancy and laboratory analysis, not to mention many other subcontractors.

At the same time, SPAQUE is also a player in the economic development of Wallonia through its shareholdings. Seven of the companies in which it holds shares make up a cluster whose job involves the collection, management and recycling of inert and construction waste. Through them, SPAQUE is involved in managing around fifteen treatment and recovery centres for this type of waste throughout Wallonia.

In this cluster, Recynam, Recyhoc, Recyliège, Recymex and Valorem are public/private joint ventures in which SPAQUE holds over twenty-five percent of the shares on behalf of the Walloon Region.

In addition to this group of specialist companies, SPAQUE holds shares in other companies where it represents the Walloon Region. In particular, it is a shareholder of Sedisol, the company responsible for dredging sediment from Walloon waterways, and Tradecowall, a cooperative waste management company in Wallonia.

Finally, SPAQUE has a subsidiary, Gepart, of which it is the sole shareholder, for the management of European funds.

SPAQUE : a few key dates

SPAQuE was founded in 1991 as a subsidiary of SRIW (Regional Investment Company of Wallonia) to manage the rehabilitation of landfills such as Mellery, Anton, Cronfestu and Florzé. At the time, the company had five employees.
Four years later, that number had quadrupled.

Over the years, SPAQUE has been responsible for the planning and rehabilitation of other landfills, including Hensies and Les Isnes.

In 2000, SPAQUE became a specialist company with 35 employees. It entered into its first service contract. Money from the ERDF (European Regional Development Fund) was allocated to the rehabilitation of sites such as Bois Saint-Jean and Moulin Dambot. SPAQuE also works to remove illegal tyre dumps.

In 2005, a second service contract was signed. Funds from the Marshall Plan Marshall were allocated to the rehabilitation of sites such as Chimeuse Ouest, Aciérie
Aciérie Allard, Cokerie Flémalle, Carcoke Tertre, SAFEA and Tubize Plastics.

In 2008, new ERDF funds were allocated to the rehabilitation of brownfield sites such as Papeterie Godin and Boch Keramis.

The Green Marshall Plan.2 was introduced in 2010 and allocated 7 new sites to SPAQUE to rehabilitate, while 27 others were held back and subjected to soil analysis.

By 2016, over its 25 years in business, SPAQUE had worked on several hundred sites (brownfield sites, landfills and tyre dumps) throughout Wallonia. It is a stakeholder in the ERDF 2014-2020 programme.

SPAQUE entered into a new management contract with the Walloon Government in 2019.

In 2020, SPAQUE started a new chapter in its history by offering a new range of contaminated soil management services to all its public and private partners.
