Description
"Reduce Disposal and Reuse" environment and our PPT courseware
Reducing the amount of garbage is a solution to the garbage problem at its source.
What are some ways we can reduce waste?
Reduce discards
What kinds of waste can be reduced in daily life?
1. Double-sided printing can save paper
2. Bring your own drinking glass when going out and buy less bottled drinks
3. Use as few or no disposable items as possible to reduce the disposal of paper and plastic...
Packaging function
1. Protection function
2. Sales function
3. Circulation function
Packaging classification
1. According to product attributes, packaging is divided into food packaging, pharmaceutical packaging, clothing packaging, hardware packaging, chemical product packaging, electronic product packaging, etc.
2. According to the classification of packaging structure, packaging can be divided into window packaging, shopping bag packaging, closed packaging, POP packaging, etc.
3. According to the classification of packaging materials, packaging is divided into paper packaging, plastic packaging, metal packaging, glass packaging, etc.
4. According to the classification of circulation functions, packaging can be divided into individual packaging, medium packaging and large packaging.
(1) Personal packaging is also called sales packaging. This kind of packaging is the most direct packaging for products.
(2) Intermediate packaging is also called wholesale packaging. The purpose of this kind of packaging is to protect the product, mainly to organize and package the items in one or more units.
(3) Large packaging is also called outer packaging or transportation packaging.
discuss:
1. Is there any waste in the packaging of the product? What facts can illustrate this?
2. What do you think of manufacturers’ excessive packaging?
Excessive packaging not only wastes valuable resources such as paper and wood, but also increases the amount of garbage and causes environmental pollution. It also increases the burden on consumers. Packaging also consumes a lot of human and material resources in the production process.
3. What material is the packaging box made of? Is it good for the environment?
Simple packaging, large packaging, bare packaging
4. How to package products to reduce waste?
5. How should the packaging be disposed of after the product is used up?
6. How should we choose the packaging of goods when shopping?
The connotation of green packaging
1. Implement packaging reduction (Reduce). Packaging should use the minimum amount under the condition that it meets the functions of protection, convenience, sales, etc.
2. Packaging should be easy to reuse (Reuse) or easy to recycle (Recycle). The purpose of reuse is achieved through measures such as producing recycled products, incineration to utilize heat energy, and composting to improve soil.
3. Packaging waste can be degraded (Degradable) without forming permanent garbage, thus achieving the purpose of improving the soil. Reduce, Reuse, Recycle and Degradable are the 3R1D principles recognized in the world today for the development of green packaging.
4. Packaging materials should be non-toxic and harmless to humans and organisms. Packaging materials should not contain toxic elements, halogens, heavy metals or the content should be controlled below relevant standards.
5. The entire life cycle of packaging products, from raw material collection, material processing, product manufacturing, product use, waste recycling, to final disposal, should not cause public harm to the human body and the environment.
Excessive packaging is divided into two categories, one is deceptive packaging and the other is luxury packaging (or exaggeratedly, it can be called "sky-high price packaging").
(1) There are too many empty spaces in the package. For example: Japan stipulates that the gap in a packaging container should not exceed 20% of the entire container in principle.
(2) The height and volume of the packaging and contents are too different. For example: Japan's "Outline for the Suitability of Product Gift Box Packaging" stipulates that the gap between the product and the inner wall of the packaging box must be kept below 5mm.
(3) Exaggerated packaging for no reason and not technically required. The packaging cost should be 10% to 15% of the product cost, which is more appropriate. If it exceeds, it will be suspected of excessive packaging.
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
reuse
Repurposing refers to using used items multiple times or in another way, and it is also an important way to reduce waste.
Which items in your home that would be thrown away as trash can be reused?
Can you estimate what proportion of all domestic waste can be reused?
What should we do?
To solve the garbage problem, efforts must be made from all aspects. First, we must reduce the amount of garbage, then recycle usable materials, and then treat the rest harmlessly.
