The researchers studied how paper industrial waste affects chickpea plants by exposing them to different concentrations of the waste for 7 days. The waste had high levels of various chemicals compared to safe limits. Surprisingly, the plants treated with the waste showed increased levels of carbohydrates, proteins, and sugars at 40% concentration. Additionally, the chlorophyll content in the plants increased with higher waste concentrations. This suggests that the waste, rich in nutrients, can be used as a cheaper way to dispose of it in agriculture.
