Resumen:
A Dutch recycling company processes -Y- fractionizes incinerated bottom ashes into widely applicable raw materials. The obtained mineral fraction consists of a considerable part of aluminium, which makes this fraction suitable for the preparation of a novel and durable binder for concrete as replacement for cement. The company seeks technologies to make highly defined pellets or similar from a fine mineral grain fraction. Technical partners sought via research or technology cooperation agreement.

Summary:
A Dutch recycling company processes -Y- fractionizes incinerated bottom ashes into widely applicable raw materials. The obtained mineral fraction consists of a considerable part of aluminium, which makes this fraction suitable for the preparation of a novel and durable binder for concrete as replacement for cement. The company seeks technologies to make highly defined pellets or similar from a fine mineral grain fraction. Technical partners sought via research or technology cooperation agreement.
Description:
A Dutch company is specialized in the sustainable recycling of waste. An important and immense waste stream comes from households, shops, the catering industry, etc. This type of waste is used as fuel to energy plants, in Dutch also called "afval energie centrales" (AEC). What is left behind in the incinerators is called AEC bottom ashes.
This AEC bottom ashes can be recycled and used as secondary building material. For instance, AEC bottom ashes is an ideal replacement for sand and rubble, and is therefore already widely used for the construction of roads and buildings.

New developments will expand the range of applications even more.The company processes and fractionizes incinerated bottom ashes into widely applicable raw materials. During this process a mineral fraction is released, which in itself does not meet the standards set by the Dutch "soil quality decision" (BBK: besluit bodemkwaliteit), but as such can obtain a positive value in other production processes of raw materials.
This mineral fraction consists of a considerable part of aluminium, which makes this fraction suitable for the preparation of an innovative and durable binder for concrete as replacement for cement. It is important that this fraction is bound in such a way that the fraction ends up in the firebox (> 1000 ¿) and is not blown away by the heat at an earlier point.

It is the objective of the company to aggregate or bind these mineral fractions to a small briquettes, grains, pellets, or the like. It should be mentioned, that the starting material (the bottom ashes) consists of a dust-like material and a sandy part with a moisture content of up to 15 %. It is important that the moisture content is either used for bonding or dramatically reduced, so that no adhering or unwanted free moisture is involved. Simultaneously, the dusty fraction should be bound or included in the pellets or the like form.
This objective can be regarded as a technological challenge since:
· This mineral fraction has a moisture content (7 - 15 %), which means that direct insertion into a firebox leads to an explosion. Therefore it is necessary to reduce the moisture content to the maximum and preferably 0% of water, while binding the dust-like material.
· The challenge is also to bind or aggregate this mineral fraction into larger, more compact granules / pellets with dimensions of 0,5 to 50 millimeters in diameter, resulting in a relatively higher weight. Consequently, this pellet with approximately 10% aluminum and an ultra-low moister content can easily and safely penetrate the furnace and thus be used in the melting furnace.
· The entire process must be carried out in the most economical manner.

The company is looking for technical partners who are skilled in the art of grain, pellet formation technology in order to solve the above mentioned objectives and binding a fine grain fraction of 0,5 to 50 millimeters in diameter, to prevent dust formation, during handling. A research or technical cooperation agreement is foreseen.

IMPORTANT NOTE: This technology request is part of an innovation challenge and is published on an open innovation platform from February the 22nd until March the 26th 2020. If an organization does express interest in cooperation with this firm before closing date, it will be guided towards this open innovation platform on which one can get in touch with the company experts. Mind that posts on this platform are not confidential. Beside open discussions on the platform, sharing of confidential information will be made possible on demand. After that, the firm will select the SMEs with whom they would like to cooperate in the development of a solution.
Technical Specification or Expertise Sought:
The company is looking for technical partners who are skilled in the art of the development of highly defined grain, pellet formation technology.
Specific expertise is sought in the field of chemistry, physics, material technology, in order to deal with the following challenges and objectives:
· This mineral fraction has a moisture content (7 - 15 %), which means that direct insertion into a firebox leads to an explosion. Therefore it is necessary to reduce the moisture content to the maximum and preferably 0% water, while simultaneously binding the dust-like material.
· The challenge is also to bind or aggregate this mineral fraction into larger, more compact granules / pellets with dimensions of up to about 0,5 to 50 millimeters in diameter, resulting in a relatively higher weight. Consequently, this pellet with approximately 10% aluminum and an ultra-low moister content can easily and safely penetrate the furnace and thus be used in the melting furnace.

Partner sought

Type and Role of Partner Sought:
SMEs, academic institutions and other innovators with expertise in the field of physics, chemistry, material or ceramic technology, separation technology or other disciplines such as micro or nano-technology or combinations thereof.
Partners are invited to contribute to a creative open innovation process, strategy thinking and further technical development in order to develop highly defined pellets or the like from a fine mineral grain fraction.
Type of partner collaboration:
The Dutch company wants to work together as equal partners, IPR conditions to be determined. This could be in the frame of a research or technical cooperation agreement or any other form that fits the purpose of this challenge.
