Testbed to study and analyze EPS-packaging disposal 

With the purpose of measuring how complex it could be to break an EPS-box apart, a  simple and logical procedure to break a box without special equipment at home is suggested. First, the box should be empty and without the lid. Then, it should be placed against a solid wall and stepped on one of its sides with an angle of approximately 45° as shown in Fig. \ref{678427}a. This procedure should be repeated for each side.
In order to reproduce this scenario a simple testbed to apply discrete force steps was built as shown in Fig. \ref{678427}b. On top of the testbed, the weight could be gradually incremented, which is transferred to the box through a metal bar and a shoe fixed to it. A linear guide was used to allow the metal bar to displace perpendicular to the ground. The box is placed on an adjustable support, which was set to 45°.  The force added to the box was calculated based on the weight of the metal bar plus shoe and the added weight on top; friction force from the linear guide was neglected.
