Bio-waste is the waste generated following food consumption and is essential in
households, public places, offices, and companies. Plastic is a material widely
utilized in everyday life, from product packaging to food packaging to office
supplies.
However, according to HSY data, bio-waste also contains a considerable amount
of plastic that is difficult to handle. That amount of plastic trash will become rejected
garbage throughout the processing process. This project was planned and
completed at HSY to analyze the data of waste rejected from biowaste pre-
treatment. Before this project, the question was how much of the plastic contained
in the wreckage was removed from the pre-treatment system. What percentage of
those plastics are, and how can the impurities be separated from the rejected
waste mix?
The figures are mainly taken from the company's annual report and analyzed the
data by quantitative method. The process of gathering and interpreting numerical
data is known as quantitative research. It may be used to discover patterns and
trends, make predictions, investigate causal linkages, and generalize results to
larger groups.
After analysing the results, I found that the amount of plastic in the rejected waste
composition accounts for 80%, and the main types of plastic are PVC, PET, PP,
and LDPE. Most of the plastic in the rejected waste is plastic from the food industry
like food wraps - they make up 70%, and the rest is from plastic bags.
