Recycling end-of-life plastics into base chemicals

With its Plastics2Chemicals (P2C) project in the port of Antwerp, Indaver will recycle 65,000 tonnes of end-of-life plastics annually. P2C will recycle polyolefins and polystyrene in high quality feedstock fit for further processing towards food grade plastic packaging. For this packaging, once it is discarded as waste, Indaver has developed a chemical recycling technology. In this process, the plastics are broken down into smaller hydrocarbon chains. This produces base chemicals as a pure end product for the petrochemical and chemical industry. The investment project, worth EUR 100 million, fits in perfectly with Indaver's vision for a sustainable circular economy. In time, P2C will lead to an annual saving of around 225,000 tonnes of CO2 and create jobs for around 60 people.

Why recycling hydrochloric acid?

Hydrochloric acid is a product mainly used by the chemical, petrochemical, metallurgical and food-processing industries. It is therefore a much-wanted primary material. Indaver has developed a sustainable recycling solution for its industrial customers providing a circular economy solution for hydrochloric or chlorinated waste that is both safe and environmentally responsible. 

Indaver recycles hydrochloric acid at 2 locations, one in France and one in The Netherlands

Video on how Indaver recovers HCl at IndaChlor

Indaver's aim with construction hydrochloric acid (HCl) recovery installations, is to recycle chlorinated waste. Indaver builds this plant close to the industry, to facilitate industrial symbiosis. This way, rather than transporting this precious raw material, Indaver can supply the HCl directly to the nearby companies through a pipeline. The energy the recovery facilities produces during the waste treatment process and when recycling hydrochloric acid, is also put to good use eg. steam can be supplied to neighbouring companies through a pipeline. With these types of partnerships, Indaver developed a sustainable solution for the region and created a circular economy that is reliable and environmentally responsible.

Expert in HCl recovery

Specialist knowledge is required to process these complex, frequently hazardous waste streams into new raw materials. As a company that handles millions of tons of waste products every year, Indaver knows how the European waste products market works and what the valuable recoverable materials are.

By recycling valuable materials from waste, we realise substantial ecological and economical benefits. We make our customers independent of the (primary) raw materials markets and avoid CO2 .

Indaver's hydrochloric acid recycling in Europe

ARP in Ijmuiden, The Netherlands

At ARP, The Netherlands, Indaver has been recovering hydrochloric acid from the three pickling lines at Tata Steel for 20+ years. Hydrochloric acid is used to remove rust after the steel plates have been rolled. Indaver's grate incinerator – installed at Tata Steel's site in IJmuiden – oxidises the contaminated pickling liquid. This creates regenerated hydrochloric acid and iron oxide. Both are 100% suitable for re-use as a raw material in the steel and pigment industry. 


IndaChlor in France

In the port of Dunkirk, France, the IndaChlor® installation of Indaver recycles chlorinated waste into a precious raw material, named hydrochloric acid. This primary resource is used by industry to use in their production process. The energy IndaChlor® produces during the waste treatment process is converted into steam and supplied to a neighbouring company through a pipeline. With this partnership, Indaver developed a sustainable solution for the region and created a circular economy that is reliable and environmentally responsible.


Inda-MP: your precious metal partner

Recycling precious metals & homogeneous catalysts from liquid waste

With Inda-MP, Indaver provides a solution to recover precious metals from liquids. Homogeneous precious metal catalysts are hard to recover but our Inda-MP installation at Antwerp (B) offers an efficient, one-stop solution, from logistics of the liquid phases until delivery of the refined precious metals. So you can focus on your production process.

Precious metals are rare and valuable metals such as palladium, rhodium, platinum and ruthenium. They are used as industrial catalysts. It is therefore ecologically and economically beneficial to recover these metals. 

Inda-MP is a thermal process that separates precious metals from solvents in pharmaceutical and chemical waste and collects them in the residues. So our customers have a constant and sustainable supply of precious metals. As a result, they are less dependent on raw materials from outside Europe. 
Inda-MP has become a trusted partner of leading pharmaceutical and chemical companies such as Pfizer and received the CPHI Sustainability Award 2022 at the CPHI Pharma Awards 2022 in Frankfurt, Germany.
