Authoritative PPT Summary
"Classification and Recycling" Environment and Us PPT
Part One: Recyclable Waste
Research nearby recycling depots or ask recycling workers what they recycle? What are these items used for after recycling?
Plastic can be melted and formed multiple times, and recycling waste plastic can reduce environmental pollution.
Recycling glass is cheaper than making it directly from natural raw materials. Because the melting temperature of glass is much lower than the temperature of melting with raw materials.
Many metals can be melted down and reused. Recycling scrap metal not only saves energy but also saves mineral resources.
Classification and recycling PPT, part 2: classification and packaging of garbage
The recycling of garbage requires the classification and concentration of usable materials. To recycle effectively, we must change the old habit of mixing garbage and classify and package domestic waste. This is the obligation of every citizen.
Is the garbage at your home separated?
Domestic waste can generally be divided into four categories: kitchen waste, recyclable waste, hazardous waste and other waste.
Waste batteries are a type of waste that needs to be disposed of with care.
One AA battery rotted in the ground can make the soil in an area of 1 square meter lose its use value.
One button battery can make 600 tons of water undrinkable, which is equivalent to a person's lifetime drinking water.
Three of the five substances that pose the greatest threat to the natural environment are contained in batteries: mercury, lead, and cadmium. If used batteries are mixed with domestic waste and landfilled, the mercury and heavy metals that leak out will soak into the soil and contaminate groundwater, thus indirectly threatening human health through the food chain.
Sorting and recycling PPT, part three: making a compost bin
About 1/3 of household waste is kitchen waste such as broken vegetable leaves and egg shells. These garbage, dead leaves, weeds, etc. in the yard can be naturally decomposed through accumulation and become useful organic fertilizers.
Let's make a compost bin in school.
Food waste, weeds, fallen leaves, etc. are mixed into the sewage, piled up, and covered with a layer of soil. The decomposition time generally takes 1 to 3 months. The decomposed garbage can be used as base fertilizer.
Sorting and packaging garbage is not difficult! As long as we all participate and develop good habits, the environment around us will definitely become cleaner and more beautiful.
