Matrix Tool increases the use of recycled plastic material (rPM or recyclate) by matching converter requirements with recyclate supply.
One of the hindrances of using recyclate is the challenge of finding suitable recyclate grades for specific products. The correlation between product/process requirements is difficult to make, and in most cases, field studies need to be carried out to validate the material selection. In this perspective, Matrix tool helps to find suitable recyclate (recycled plastic material or rPM) for converters or producers who want to replace virgin plastics. Furthermore, recyclate suppliers or traders can use this tool to sell their materials more efficiently.

Do you face problems in finding the right recyclate or rPM (recycled plastic material) for your virgin material or are you looking to increase the publicity of your recyclate? The matrix tool can help you in this regard. Some of the use cases of the Matrix Tool are as follows:
-One company wanted to use recyclate HDPE instead of virgin HDPE in their product. In the beginning, the virgin material properties were determined through tests. Those properties were put into the matrix tool. After that, the tool provided a ranking of the potential PE or PE/PP recyclates using the database. From the ranking, 3 recyclates were chosen and the suppliers were contacted. The recyclates were ordered and tested for verification of their properties. After the tests, one out of the three recyclates was recommended for their product.

European Commission has the goal of reaching a circular economy and plastics have a crucial role in reaching this goal. Plastics are used in many sectors such as packaging, building and construction, textiles, consumer products, transportation, electrical and electronics, and so on. Thus it is important to close the plastic loop to reach a sustainable and resource-efficient economy. One of the ways of achieving the goal is to use recyclate (recycled plastic) as an alternative to the virgin material for new plastic products. Although there is a high demand for recyclate material in the market, a very small amount of product is made from recyclate. This indicates the presence of some challenges in the uptake of the recyclate. Therefore, the main goal of the Interreg Di-Plast Project was to increase the uptake of recyclate among the companies. The Matrix Tool was developed for this purpose. Deatils about the Di-Plast Project can be found at [https://www.nweurope.eu/projects/project-search/di-plast-digital-circular-economy-for-the-plastics-industry/]

- When the converter puts their desired material specifications (polymer type, process technology, properties etc.) in "Recyclate Supplies" tab of the tool, it will search the current recyclate supply for exact matches. If no exact matches exist in the current database, it will use an algorithm to recommend alternative recyclates which do not exactly match the filled-in specifications.
__Recyclate Supplies:__ This section contains the database of the existing recyclates. Converters can choose the material specifications (polymer type, process technology, properties, etc.) they want to see by clicking on the "column" tab. When they fill in the values or specify the ranges for those specifications, the tool will search the current recyclate supply for exact matches. If no exact matches exist in the current database, it will use an algorithm to recommend alternative recyclates which do not exactly match the filled-in specifications. In addition, suppliers can add information about a new recyclate by clicking on the "create recyclate" tab.

__MFI (melt flow index):__ This property gives an indication of the fluidity of the molten polymer. It is an important value for the prediction of processing behaviour and material selection. The MFI could be seen as a measured viscosity at a single temperature and shear rate. It is often measured at a specified temperature and weight. However, due to the fact that the viscosity of polymers is shear-dependent, the MFI could also be measured at multiple weights (shear rates).

__Impact strength:__ It denotes the energy needed for the fracture of a material. The greater the value, the more resistant the material is to breaking upon impact. It can be measured via Charpy or Izod methods. Samples could be measured notched or unnotched. Notched values are lower than unnotched values due to the limitation of energy dissipation throughout the sample. Furthermore, the impact strength can be measured at different temperatures to predict impact behavior in different environments.

Do you face problems in finding the right recyclate for your virgin material or are you looking to increase the publicity of your recyclate? In this case, the Matrix tool is the perfect candidate for you. Over the years the tool has been used by several companies (both converter and supplier). Some of the use cases of the Matrix tool are as follows:

-One converter wanted to use recyclate HDPE instead of virgin HDPE in their product. In the beginning, the virgin material properties were determined through tests. Those properties were put into the Matrix tool. After that, the tool provided a ranking of the potential PE or PE/PP recyclates using the database from the "recyclate supplies" section. From the ranking, 3 recyclates were chosen and the suppliers were contacted. The recyclates were ordered and tested for verification of their properties. After the tests, one out of the three recyclates was recommended for their product.
-One supplier sells polyolefin recyclates. They can see the demand in the "recyclate requests" section of the Matrix tool. In addition, they can see the overview of the producer requests using the filters. This in turn also helps them to optimize their recyclates according to the demand.
