The system wastebasket “the double” made of opaque and matt plastic has a paper capacity of 20 liters and an attached container with a colored lid of 9 liters for wet and other waste. This two-chamber system makes this system wastebasket ideal for separating waste in the office. We recommend a garbage bag size of 35 liters for the main container and a garbage bag size of 20 liters for the attachment container.
