We are specialised in the realisation of projects and systems for the handling, processing and upgrading of residues and waste materials. We can offer turnkey solutions from the feasibility study, design and engineering up to and including project management, support permitting, procurement, contracting, hiring, commissioning and training.

We are active within the following technologies:


1. Bottom ash recycling:

After the incineration of MSW, ashes remain. These ashes contain metals (both ferrous and non-ferrous) – stones – sand – unburned. In the bottom ash recycling installations, the unburned is recuperated; sand, stones, ferrous and non-ferrous are recycled and sold.

Wet treatment

During the washing process of the ashes, the leaching process of sand and stones has been improved and speed up. The quality (and value) of the metals is increased.

Dry treatment

After dry treatment of the ashes, the sand and stones have to go to an intensive ageing process to reduce the leaching of both fractions. Ferrous and non-ferrous are recycled and sold.

2. Recycling of steel slag:

Steel slag, in combination with the refractory of the furnace, contains ferrous, stainless steel 304 and 316, together with valuable stones. SS 304 and 316 are separated. Some of the stones are recycled.

3. Metal scrap recycling:

Mixture of non-ferrous scrap is washed and separated on density in a heavy medium into individual non-ferrous metals like cupper, lead, zinc. Due to the washing process, each of the non-ferrous metals are clean and have a high value.

4. MSW Packing recycling:

Packaging waste (“Groene punt” Belgium and “Grune Punkt” Germany) like Aluminium cans, PET bottles (white, green, bleu, red), HDPE, TETRA, are sorted automatically with the use of IR technology and pressed into bales. Each of the fractions are re-used in the industry (sweaters, new cans, …)

5. Pre-treatment in composting and digesting installations:

Organic waste and wet biomass are screened, sorted on metals, sand and stones, plastics before it can be transferred into a green gas/green electricity in several digesters (project Cambi) or into compost as a fertilizer (project Stercompost).
