Design for all

Hi, taking out the trash, can be problematic issue for disabled people due to the fact that city infrastructure is not completely adapted for the disabled people. For example containers are too high for people on wheelchairs, require using of two hands to open it and throw the bag. This is also a problem for many others disabled people. I am a student of industrial design and I would like to solve the problem on my graduation project. I'd be thankful for complete my questionnaire.

1. What is the most difficult in taking out the trash?
2. In your opinion, how do people deal with this issue?
3. How do you think designers/producers could somehow solve this problem?
