Indaver Molecule Management®

Glass, paper and plastic are widely recycled. Our Indaver Molecule Management® (IMM) takes recycling one step further. With Indaver Molecule Management® we look for new and better ways to recover valuable components in household and industrial waste streams safely and efficiently. We do that by looking at the smallest building blocks, the molecules. Using this IMM approach Indaver has already successfully recovered hydrochloric acid, palladium and iodine. R&D projects for recovering sulphuric acid, fluorine and valuable metals are also underway. In 2017, preparations began for 2 major projects: the plastics2chemicals (P2C) project with a recycling solution for end-of-life plastics and IndaChlor® in France.

IndaChlor®: sustainable solution for chlorinated production residues in Dunkirk

IndaChlor®, the new treatment facility that Indaver is building in the French port of Dunkirk, will extract hydrochloric acid from chlorinated residual waste, primarily from the PVC industry. Ecophos, manufacturer of food phosphates and a neighbouring company of IndaChlor®, will use the hydrochloric acid recovered by Indaver in its production process. It will be supplied directly via pipelines. The energy created by IndaChlor®’s treatment process will be supplied via a pipeline to another neighbouring company. These are great examples of industrial symbiosis. The start of the build has been planned for 2018.

Plastics2chemicals: from plastic waste to raw materials for the chemical industry

Indaver is focused on finding innovative and sustainable solutions for plastics. In our facilities in Willebroek we sort recyclable plastic packaging and get it ready for use as a raw material for the recycling industry. We are now also constructing an innovative solution for end-of-life plastics that can no longer be re-used. In these plastics2chemicals (P2C) facilities we will break down these plastics into smaller hydrocarbon chains. This thermal, molecular recycling will produce high-grade raw materials for the chemical industry.

Regeneration of hydrochloric acid

Since 2001, the Indaver ARP (Acid Recycling Plant) has been recovering hydrochloric acid from three pickling baths at Tata Steel, Ijmuiden, in the Netherlands. The hydrochloric acid is used to prevent corrosion of the steel slabs after rolling. The pickling acid used is oxidized in the Indaver ARP (located within the Tata Steel property at Ijmuiden, just north of Amsterdam). This oxidation produces regenerated hydrochloric acid, which is then reused by Tata Steel. This is a sustainable solution, where waste is transformed into raw materials. It takes place within a totally closed loop.
The iron oxide recovered is also reused as a raw material in the steel and pigments industries.
