A reflective journal is an instrument for practicing writing and critical thinking. Use the notes and feedback left by the instructor in a previous assignment to reflect on what you have learned so far.

First reflect on any feedback, record your thoughts, responses and reactions. Be sure to note questions you have, or any confusion that may arise.

I am looking for your honest reflection and thoughts on your own writing and your understanding and response to my comments. There are no right or wrong answers, but I am looking for evidence of consideration and thought. A superficial analysis will lose points.

You should aim for about 300-500 words in your reflection. This is informal writing so I’m not looking for any particular format; however, you should still be grammatically correct and clearly written.

  • Trash system contains both recyclable and non recyclable substances.
  • System requires high amounts of money because of labor cost.
  • Difficulty in classifying wastes
  • Need for more economical automatic system

The garbage recycling system tried in Philadelphia is due to the challenges the city is going through. They include; the difficulty to recycle the trash from different parts of life because of the mixture of both the recyclable and non recyclable trash,. Also, the some of the old methods used are highly costly because they require vast employees. There is also the difficulty to distinguish wastes and thus mot plant give up along the way. Therefore, there is need to develop a more economical as well as effective plant.


Automatic Recyclable Garbage Classification (ARGC)

Separate trash

Classify wastes

Information storage

Reduce the wastes in Philadelphia

Clean cities

Creating employment

Some of the important functions carried out by the new system developed is to separate trash that is recyclable from the non recyclable. Secondly, it will classify the wastes according to their difference in their densities . Also, the system has the ability to store information about different elements that make up the trash. The reasons for this is to create employment as well as reducing the amount of wastes in the town and thus the ability to have a clean and conducive town.


  • Trash are characterized by unique densities.

The major challenge with separating trash is the fact that they are all collected together from the households as well as industries. Therefore the differnce in densities posse a great challenge.


The steps include:

  • Separate trash to different recyclable materials
  • The recyclable trash is then separated according to its different densities
  • The ability to store information is important in ensuring that the wastes are separated according to difference in densities.

The steps followed by the system include Separate trash to different recyclable materials. The recyclable trash is then separated according to its different densities. The ability to store information is important in ensuring that the wastes are separated according to difference in densities.


  • Installation of the projects plants
  • Training of the employees
  • The project is projected to cost a total of 199500 dollars

Some of the primary activities that will take place before the system runs is that the team will carry out a feasibility tests within the regions where the plants are to be installed. Proving success, will therefore mean that the system will be installed then followed by the recruitment and training of the personnel according to the specialization and department. The whole project will cost 199500 dollars.


  • It can be upgraded to ensure flexibility.
  • It is projected to be able to adapt to the emerging need.
  • Ability to be flexible according to the locale and availability of trash.

The system can be upgraded in the future to cater for the arising needs that are not covered in the initial point of development. The upgrade will allow the system to be flexible in operation in terms of locality and availability of the trash.
