According to the report, industry insiders said that degradable lunch boxes are usually much heavier than disposable plastic lunch boxes. It doesn't make much sense if they are only partially degraded. Even if they are completely degradable, they will take six months to two years to degrade under certain conditions and will not' disappear' immediately. After being discarded, they still need to be collected and transported as garbage.
Experts said that if the terminal treatment facilities of degradable lunch boxes are composting plants or landfills, it still makes sense. If the terminal is an incineration plant, it is basically meaningless. Moreover, the manufacturing process and treatment and utilization process of degradable lunch boxes also have resource and energy consumption and pollutant discharge, so it is necessary to investigate its environmental friendliness from the perspective of the whole life cycle.
To reduce the pollution of take-away lunch boxes, it is necessary to systematically and scientifically evaluate the take-away logistics, waste discharge, treatment and disposal from the whole life cycle analysis, so as to avoid taking measures in a single link. In fact, the production process of paper lunch boxes will also have environmental impacts such as water pollution, and it is difficult to recycle food after it is placed. It is necessary to evaluate whether its environmental impact is really smaller than that of plastic lunch boxes from the whole life cycle.
I hope that the pollution problem caused by take-away lunch boxes can be solved as soon as possible!
