The Polybag is filled with bitumen that is exactly cooled down to a temperature slightly higher than the softening point - and lower than the melting point of the plastic liner material of the bag into a special Polyolefin Bag and is let down to harden and become solid for easy handling and cold transportation.

​

The inner bag is placed in a very solid and firmly designed 3ply outer layer of special polymeric bags. These bags are environmentally friendly and safe to handle, as it allows transportation and storage of large quantities of bitumen for long periods of time reducing energy costs and avoiding any leftovers in drums or unnecessary heating like in bulk vessels. The outer layer is cut open and the inner liner melts with the bitumen during the melting process using specially designed high-tech melting units which have a capacity of 4 tons per hour.

​

The reduction in carbon emissions due to long haulage of heated bitumen is avoided in all types of cold packing, however, with the bag, an additional benefit is that there are no environmental leftovers and bitumen is only melted when and where needed. The bags also save about 8% of energy consumption in comparison to drums melting or Bitutainers.

​

• In general, the waste which remains in drums accounts for 3-4%, with Polyethylene Bag bags there is no residual waste;

• The packaging does not pollute the environment, as drums are hard to recycle and re-sell, especially for projects where the Bitumen is melted distantly from the port at deep inland locations.

• The system is easy for shipping and storing;

• Bitumen is delivered and melted at a convenient location;

• The cost of labor is reduced;

• Due to more efficient heating (only the bitumen is heated and not the drum), carbon emissions are reduced;

• Due to using and melting bitumen only when needed, the constant energy consumption to keep bitumen heated is avoided, which results again in lower carbon emissions;

• Due to cold shipment of the cargo across the world, saving of more carbon emissions in comparison to bulk shipments, which requires constant heating during ocean voyages
