Sustainability for materials handling

motan defines sustainability as optimizing the configuration of processes while also taking resource conservation, energy efficiency, material recycling, circular economy and environmental friendliness into account. Our products, particularly in the areas drying, conveying and dosing, contribute greatly to sustainability. We believe it is extremely important to look at the sustainability of the entire process as a whole rather than single measures or individual functions.

Material drying and injection molding typically use a lot of energy, which results in a lot of thermal discharge being generated during the running of the machine. We try to utilize as much of this thermal discharge as possible with the help of heat exchangers. For drying, this occurs process-internally during the regeneration of the desiccant, or externally via heat exchangers located at the rear of the drying bins. One of our customers, for example, uses the thermal discharge of his system to heat his communal swimming pool. It is also our goal to keep processes in thermal balance by focusing on the respective regulation mechanisms which adjust performance according to their consumption and keep performance consistent.

Our ETA plus® drying technology

Our ETA plus® drying technology contributes greatly to sustainability by only making available the air flow that is actually needed. ETA plus® utilises senor technology which determines the optimal energy requirements for the drying process and constantly readjusts it in a control system. Additionally, the ETA plus® heat exchange technology can be used for high temperature processes to feed return air thermal energy directly back into the process and so cool the return air as required. 

To prevent energy losses after drying, we recommend investing in a closed-loop conveying for material conveying from the drying system to the processing machine. This prevents the material from reabsorbing moisture and the material maintains its temperature. During the next processing process, the material then no longer needs to be heated as much. This can also be combined with the conveying technology IntelliFlow, which optimizes the conveying speed so that the material is conveyed gently and energy requirements are reduced. This is what we consider to be sustainability. 


With our patented double-walled stainless steel material feedline SilentLine, which is comparable to double glazing, we can achieve three different sustainability goals for pneumatic conveying: noise emissions can be noticeably reduced, heat losses are prevented and leaks are easier to find. SilentLine has been proven to reduce noise levels by at least 12 dB(A).In combination with IntelliFlow, a further noise reduction of6 dB(A) is possible. Here, the combination of different measures once again results in the best possible result.

As an ancillary supplier for materials handling of bulk material, motan has a linking function between plastic manufacturing and processing industries. It is our goal to think beyond borders. Together, we can find new and innovative solutions that help save resources, recycle materials and improve energy efficiency. We are convinced that sustainable action is the key to added value.
