"Classification and Recycling" Environment and Us PPT Courseware

For some wastes in life, we can recycle them from garbage and reprocess them. Doing so will not only reduce the amount of garbage, but also save a lot of natural resources.

What kind of waste can be recycled?

How to recycle them?

Recyclable waste

Research nearby recycling depots or ask recycling workers what they recycle?

What are these items used for after recycling?

Sorting 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.

At home, do we separate the garbage?

Investigate the classification requirements for domestic waste. How many categories are they generally divided into?

What waste does each category contain?

What kind of recycling bin should be put in?

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.

My design plan

Composting does not require a large area. If you are just dealing with fallen leaves, one square meter will be enough. Select a corner, dig a shallow pit first, and set the excavated soil aside for later use. Place a compost box on the pit, and add organic matter such as fallen leaves, layer by layer, and layer by layer of soil. Sprinkle some water to keep it moist to facilitate fermentation and ripening. During this process, the compost will settle due to decay and shrink in volume. After half a year, there will be a box of good fat.
