MAterials from solid and liquid industrial process REsidues

The program MaRes is about recycling of ‘Materials from solid and liquid industrial process Residues’, and aims at creating and demonstrating an operational, flexible toolbox to recover metals and valorize residual matrix into building materials.

The increasing demand for raw materials, their price of e.g. rare-earth elements, the production concentration in e.g. Asia and Africa confront Flanders with a number of challenges along the entire raw materials value chain. MaRes will target lower-concentrated, secondary resources like metallurgical slags, bottom ashes, fly ashes and slags from thermal treatment processes, industrial by-products such as bauxite residue, goethite, phosphogypsum and aqueous waste streams from metallurgical and thermal treatment processes.

Mares toolbox

MaRes aims at creating and demonstrating a toolbox different concentration, extraction and valorization technologies:



MaRes is driven by industrial demand, guided by EU and Flemish policy and exploiting science. Room is left for additional companies and scientific competences for the valorisation of other material types as well as for the deployment of eco-design and business models to enhance residue valorization:

MARES Toolbox

MaRes brings together various industrial stakeholders and knowledge institutes representing the full value chain from End-of-Life (EoL) product recycling and residue production, to pre-processing, water treatment and metal recovery, to mineral valorisation of new materials.

There is a link with the activities in the EIT Raw Materials, as part of the MaRes partners are also active in this large European network that aims to boost competitiveness, growth and attractiveness of the European raw materials sector. See EIT Raw Materials website for more information.

Stiff Impact and Fire resistant thin composites: this project aims at the development of a composite material with an inorganic cementitious matrix and textile/ fiber reinforcement capable of resisting impact and/or high temperatures. Fibers will be treated for better compatibility with the matrix. Possible future production of structurally loaded composite parts on the base of prepregs will also be studied.


TOGETHER aims to develop and produce environmentally friendly concrete building products with high chemical resistance for the agricultural and chemical industry. The products will incorporate secondary resources from Flemish industries. The project will bring more understanding on how to improve the durability of concrete with high content of metallurgical mineral products, with regard to chemical attacks.


The project aims at the durability of MFS-Slag Concrete. By incorporation of MFS-slag in concrete mixtures at high cement and/or aggregate replacement levels, DUSC strives for: 1) maximum residue valorisation and avoidance of waste disposal, and 2) more durable and sustainable reinforced concrete structures, with a low carbon footprint, high service life and good recyclability. DUSC deals with two cement replacement levels.


GHRANTE targets the development of innovative, recyclable inorganic polymer-based materials based on slags from the non-ferrous metallurgy. GHRANTE will develop: 1) a full portfolio of properties and durability data for inorganic polymer-based materials that will be used in 2) value-added tyre/noise and rolling resistance reducing, with high skid resistance and durability and/or fire-resistant prototypes.


SMART stands for Sustainable Metal Extraction from Tailings and is the first ever project in Flanders that is 100% dedicated to finding zero-waste solutions for tailings, i.e. the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. SMART aims to develop a generic toolbox for the sustainable metal extraction from a wide variety of both historical and fresh tailings.


Various industrial activities cause critical raw materials (CRM) emissions in wastewater: chemical and metallurgical industry, ore processing, surface treatment of metals, specialty glass productions and email sector. However, no technologies exist to recover CRM from such matrices at affordable economics. The new technology developed within Get-A-Met will be applied for the recovery of CRM from diluted water streams.


ASH-CEM stands for novel Cements & Building Materials from Incineration Ashes. The ICON project targets the development of new cement based and carbonation based binders making use of processed incineration ash from Municipal Solid Waste Incinerators (MSWI) plants, in order to give them a useful destination and avoid landfilling. These novel binders will be used in prefabricated and ready mix concrete.


SuperMEX targets the sustainable transformation of new and landfilled solid industrial residues into metals and inorganic polymers using a SUPERMetalEXtractor. The project focusses on metal extraction from industrial solid residues and the subsequent valorisation of the residual mineral matrix. SUPERMEX develops both generic and specific knowledge, ranging from the lab to industrial scale.
