When you use recycled plastics instead of virgin material, you automatically avoid the production of climate-damaging greenhouse gases. And the amounts are very considerable indeed. At regular intervals, we have the figures calculated by the University of Magdeburg-Stendal: In 2013, for example, the 27,000 metric tons of regrind material that left our company helped to save nearly 60,000 tons of CO2 because it was used instead of primary material. This corresponds to the emissions from 8,000 mid-class cars circling the Earth.
Since 2014, mtm has issued its customers with a certificate showing their share of the reduction of CO2 emissions according to the volume of regranulate they purchased from mtm. This provides them with documented proof of their company’s activities in the field of sustainable development.
mtm can currently process up to 75,000 tons of input product a year. We obtain our base material from various sources. In the procurement of our raw materials, we focus on plastic waste from pure, high-quality plastics. These is made up of used polyethylene and polypropylene packaging with only a very short service life behind it, and plastics from household bulk waste collections, commercial waste and industrial scrap. Because the plastic packaging waste that has only been in service for a very short time is, after processing by us into recyclate, subsequently turned into high-quality, long-lasting products by our customers, we prefer to speak of "upcycling" rather than "recycling".

Unfortunately, our processes are relatively energy-intensive, which is why we attach major importance to using all the existing energy-saving potential. A modern energy management system takes care of this. Our production process is certified to ISO 9001-2015. We have also affiliated ourselves to the European certification standard, EuCertPlast, and we naturally comply with all the requirements specified in the REACH and CLP regulations, which we monitor regularly.
The plastic waste is generally delivered to us in bale form, after which it is cut in large shredders. We then use a dry mechanical process to remove any impurities contained in the baled material (metal, wood, glass, sand, stones, paper etc.). After pre-sorting and a further shredding step, the plastics are then sorted by type and washed. We concentrate on the two polyolefins, polyethylene and polypropylene, which we separate from each other and sort according to colour. In the combined washing/separating stage, we then separate off all undesirable plastics, such as PET, polystyrene and PVC, together with any other materials sticking to them. The washed, ground material is then dried and finally processed into regranulate. At this stage of the processing, the material is compressed, melted at 180 – 240 °C, mixed with the required additives, kneaded (plasticised), finely filtered (180 µm), degassed under vacuum, fully mixed (homogenised) and finally, in water, is converted into the characteristic pellet shape. This compound/regranulate is then dried and homogenised once again in mixing silos before being packed.
The compounds/regranulate material produced in this way is of high quality and ideal for further processing.
We recycle plastic waste into high-quality regrind material and compounds for your plastic products. The regranulate produced by mtm plastics can be used for a wide variety of applications.
To enable our recycled products to compete with virgin material, it is important that “quality”, “reliability of supply” and “consistency” are an integral part not only of our business policy, but that they also apply to our raw material procurement.
We supply our customers with plastic recyclate of consistent quality. Our branded Dipolen® products are based on either polypropylene or polyethylene, modified and compounded according to the customer's specifications.
Our Technical Support is on hand to ensure smooth implementation. In this context, please consult the page on our Dipolen® regranulate product line.
The advantages of our regranulate and compound materials
Our plastics processing customers use our branded regranulate material both in injection moulding and in extrusion. The customer decides on the properties of the regrind material. According to his wishes and specifications, we incorporate additional additives and/or fillers into the production process (compounding). In this way, we can tune the colour, processing temperature, flow rate, breaking strength and impact resistance to the requirements.
Regranulate from mtm plastics is used in many high-quality end-products:

Together with Borealis and in coordination with many other industry representatives, mtm has developed ten handy codes of conduct for recycling-friendly design. They are addressed to all packaging experts who are interested in the connection between their design decisions and plastics recycling. Following the "Ten Common Rules", you will find an FAQ catalogue that goes into more detail on a number of points. If you have any questions or comments, please feel free to contact us. We look forward to every exchange on this important topic.
At Borealis, we work closely with our value chain partners to develop polyolefin-based material solutions and concepts that accelerate the transition to the Circular Economy. There are promising opportunities for business growth in replacing the linear model of “take-make-dispose” with a more circular one focused on recycling. Polyolefins are an ideal material for designing packaging that can be recycled and these Design for Recyclability (DfR) codes need to be adopted to optimise their recyclability.
DfR incorporates recycling codes of conduct into the design process keeping in mind the end-of-life aspects after its original intended use. These DfR codes are an essential tool for delivering to market plastic packaging, with the right functionalities, yet also, helps conserve natural resources and minimise waste (including product waste) disposal or incineration and littering. DfR can maximise recycling rates for all kinds of plastic packaging because it makes separation and reprocessing more efficient. It also ensures the steady and affordable supply of high-quality recyclates, from so called “recycling-ready” packaging. Those recyclates also have a significantly lower CO2 footprint and require less fossil fuel in the manufacturing process versus production of virgin resin.
While there are many aspects of plastic packaging design that make packaging “recycling-ready”, we have identified three key overarching codes of conduct when designing the function of the packaging eg, preservation, safety, wastage
The following “dos and don’ts” help our partners and customers navigate the relatively new and complex field of DfR in polyolefins. These codes are based on current circumstances and technologies used in European countries and we recommend that you regularly consult trade and industry bodies such as Plastics Recyclers Europe (PRE) and the Institute Cyclos-HTP in order to stay up to date on emerging technologies, waste stream evolutions, and new sorting and reprocessing capabilities

It is the designers who take the first major step in improving the recyclability of plastics packaging. The main aims of "RecyClass" are to give them the necessary support, sensitise them to aspects of recyclability, and provide them with a practicable tool for this purpose. The tool, developed by PRE, is an interactive online questionnaire to help designers and manufacturers establish how recycling-friendly their packaging is.
