Maximum material, maximum energy

Indaver is a supplier of high-quality materials and sustainable energy and aims to expand this role further. We are continuously looking for new and more efficient ways of recovering materials and energy.

Indaver partners one of the largest remediation projects in Europe

Indaver is a major partner in the remediation of a hazardous waste landfill site in Bonfol, Switzerland. It is managing the removal, transport (via rail) and the preliminary treatment onsite, with the Indaver incineration facilities in Biebesheim, Hamburg and Antwerp treating the waste. Using 624 containers, customised specifically for this project, Indaver can safely transport the waste without risk of leaks and spills. Spanning 6 years this project, when complete in 2016, will result in the recovery of approximately 200,000 tonnes of contaminated chemical waste. That Indaver is involved in the remediation of this site, one of the largest in Europe, demonstrates its expertise in this field.  

ECLUSE, heat network in Port of Antwerp

Indaver and SLECO treat over a million tonnes a year of non-recyclable household and similar commercial waste in their grate and fluidised bed incinerators. ECLUSE, a joint venture comprising Indaver/SLECO, Infrax, Maatschappij Linkerscheldeoever and FINEG, will channel the steam generated during the incineration process through a 5-kilometre long steam pipeline. Six companies from the chemical and logistics sector in the Waasland Port near Antwerp, Belgium, signed letters of intent in 2015 for the supply of this green heat from ECLUSE. It is set to become one of the largest industrial heat networks in Europe. Once operational, it will produce at least 5% of all green heat generated in Flanders, Belgium.

Indaver Molecule Management

Residual waste streams are increasingly seen as potential raw materials at a molecular level. As a company that handles around 5 million tons of waste products every year, Indaver knows what the valuable recoverable materials are. Our Indaver Molecule Management is intent on reintroducing materials from waste into the materials loop as much as possible. We examine the tiniest building-blocks – molecules – of the waste streams treated at Indaver to see which ones can be reused safely and effectively, with a quality that is no different from the original product. 

Phosphorus recycling

There is a growing demand for phosphorus from agricultural companies, the food industry and the pharmaceutical industry. There is, however, a limited supply. This is why Indaver is also focusing on recovering phosphorus from, for example, animal dung, organic-biological waste, wastewater, water purification sludge and incinerator ashes. The innovative research is focused in particular on recycling phosphorus from the wet elements in the fermentation facility, from liquid residual waste streams, such as phosphoric acid and leachate from landfill sites, and from solid residual waste streams, such as ashes from the biomass and waste-to-energy facilities.

VGF digester at Alphen aan den Rijn, the Netherlands

Bio Power Alphen is the latest generation Vegetables, Garden and Fruit (VGF) waste digestion facility from Indaver. Officially opened in April 2015, it is the only facility in South Holland that can both digest and compost VGF waste, green waste and biowaste from the food industry. The facility accepts VGF waste from municipalities across the wider region, and from this Indaver recovers four high quality raw materials: compost, biomass, green gas and liquid CO2, .

In doing so, Indaver once again successfully closes a materials loop. Another important step towards the circular economy.
