This should be a topic composition. The landlord wanted to write an argumentative essay, but after reading the whole article, he felt that he was piling up examples. There are too many examples, and there is no good connection between the discussions.
Individual examples are not appropriate. The starting point of the topic is to improve the quality of goods and create greater value through people's whimsy or reasonable arrangement. The examples of soap and soda in your composition just show that the invention of these two things is a coincidence.
There is too little introduction at the beginning, so it is better to tell more, both positive and negative. Emphasize the role of people's whimsy.
It's better to add a negative example to the argument used: even a treasure is an ordinary thing without thinking and deliberation.
The first example (medical record card) is poorly written (I don't know how to write it, so I can remove it).
The second example (soap) and the third example (soda water) can be removed.
Use the fourth and fifth examples directly (sculpture is a typical example of turning waste into treasure)
Add another negative example.
Then you have completely ignored the final conclusion, and you should draw the conclusion in paragraph 1-2.
