Summary of PO meeting (9.11.2018)

The First meeting with the leading staff members of the project we are going to work started as usual. Every one was little bit nervous and waiting to hear what did Renotech have to offer for us and the backround information of the up coming project.

First was a quick introduction round where they told us who they were and what they did, followed up by us telling who were we and why did we chose this project. After they found out that allmost all of us were studying towards chemical engineering they told us that the main part of the project would focus towards laboratories and working on the adsorption part of light crushed aggregate soil.

Then they talked about the other project that they were involving in and how it was very similiar to our project. The other project is Circular Project which utilizes large land masses that are being dug up from the port of turku for construction purposes.  The circular project was conserning on cleaning these land masses from mercury and other hazardous materials and using for example the clay from the dug up material. But the real connection with our project and this one was the absorption of mercury as Renotech Oy wanted to link these projects in collaboration.

After this they therally introduced us to the project we were going to work (Light crushed aggregate soil recovery). First was a quick talk about possible forest fertilization. Next was the possible adsorbtion of the real hazardous materials such as the previously mentioned mercury but also CO2 and phosphor.

CO2 will be adsorbed as the material ages and this wil go as a carbondioxide- bank so to say.

Their material was close to the material ”Leca” with atleast 1% of fly ash implented into the recipe which adds the element of fighting against acids alot better.

They said that theu alreeady had a batch of 200m^2 as a pilot batch and we could use this.

The possible spray production and 3D-printing was discussed but they said that 3D-printing is a bit early statement of this material even though it takes very short time for the foam to harden.

We agreed on weekly meetings where we inform them about what has happened and what will happen on next week in proximatelly 20min meetings. They also said that they will provide us the reagents for the testing and firstly see their internal inventory before buying new stuff for tests.
