While using plastic waste as a form of payment for education presents numerous benefits, there are potential challenges and drawbacks to consider. One challenge could be the fluctuating value of plastic bottles in the recycling market, which may impact the stability of fee payments. Additionally, logistical issues such as collection, sorting, and transportation of plastic waste could pose operational challenges for schools. There might also be concerns about health and safety risks associated with handling large quantities of recyclables. Moreover, dependency on this model alone without diversifying revenue streams could lead to financial instability if there are disruptions in the recycling industry.
