Here are my thought:
If you help in kitchen after your meal to clean up your plates and cutlery, I bet you know very well that this design is far beyond to compromise the space that you need to dry your plates and cutlery.
For those who are using dish washer at home, this might become a decoration for your kitchen. For people like me staying at equator, washing our cookery manually and drying it using cloths or just leave them on the drying tray, this is of course not enough. If I am single... hm.. maybe it helps, but what about the space for cutlery?
Perhaps should consider to merge this design with following picture:
With this design, now at least the user can have space for cutlery and glass or cups.
Some times simplicity does not mean user friendly and realistic.So as a designer, please put your end user into your design consideration, else you are wasting your effort, resources and user might need to spend extra money to buy another "friendlier" tray and this will defeat the purpose of being environmental friendly.
