overpacked:

Some health care products sold on the market are filled with foam plastic in a large cardboard box, with several small cartons embedded in the foam plastic. Inside the small cartons are plastic bags, with a little bit of health care products in the plastic bags. The same is true for gift box moon cakes and tea. The packaging waste of these products accounts for more than 80% of the total volume. Some products are also packaged in multiple layers, including cartons, plastic bags, and a large plastic bag. More than 50% of these products are packaging waste. This is called excessive packaging or redundant packaging.

Relevant media have disclosed that for every 10 million boxes of wooden box mooncakes produced, 400 to 600 trees with a diameter of more than 10 centimeters need to be cut down for packaging supplies. The loss of bamboo in the production of bamboo mooncake boxes is even more alarming. In addition, a large amount of resources such as steel, plastic foam, and paper are used in mooncake packaging. Once these mooncake packaging materials are discarded, most of them will become worthless under the current garbage disposal methods. On the contrary, they will greatly increase the amount of urban garbage disposal.

They are expensive before the festival, but they are mixed with garbage after the festival. Behind the rise and fall of this small mooncake box, consumers have paid a high price for it, and the entire society has also paid accordingly in terms of resource utilization, environmental protection and inheritance of traditional culture. Huge social costs.

City surveys show:

30% to 40% of the garbage is from commodities and excessive packaging.

1. What materials are the packaging boxes made of? How do we dispose of the packaging materials after the goods are used up?

(1) Sold as scrap

(2) Throw away directly as garbage

2. What is the difference between the volume of the packaging box and the volume of the product itself? What did we find?

Some packaging is unnecessary, and some packaging is seriously more than it actually needs. (overpacked)

3. What do we think of the excessive packaging behavior of some manufacturers?

Excessive packaging not only wastes valuable resources such as paper and wood, but also increases the amount of garbage and increases the burden on consumers.

4. What kind of packaging should we choose when shopping?

Choose products with moderate and simple packaging. Products with moderate and simple packaging are participating in environmental protection actions.

To reduce packaging waste, I recommend

1. Bring your own shopping bags, use less plastic bags, and bring your own lunch boxes

2. Choose green packaging, such as simple packaging, large packaging, and naked packaging.

3. Reuse old packaging and recycle recyclable plastic and glass packaging.

4. Formulate legal provisions on packaging and strengthen publicity

Reducing the amount of garbage is a way to solve the garbage problem from the source. Recycling raw materials from garbage can not only reduce the amount of garbage, but also save resources.
