This is the most popular practiceSo what exactly do coconut shells, durian shells, and mangoes do?
Coconuts are mostly grown in tropical areas with high temperatures and rainfallThere is little cultivation in southern China, and India, Malaysia, the Philippines and other places are rich in coconut production areas.
Coconuts grow on the tree, appearing in clumps in the center of the tree's top, and most of the time, we areEat the pulp of the coconut and the juice inside.
For coconut-rich India, coconut can be used for multiple purposes, coconut water and coconut meat can be sold to customers, whileLeftover coconut shells should never be thrown away as garbage
The outermost hard shell of the coconut shell can be used as a handicraft, and the beautiful and meaningful patterns are carved on the shellfor decorations placed in the house.
Coconut shells can also be used as flower pots, reused, harmless and environmentally friendly.
It can also be used to create a variety of shapes.
After removing the hard shell on the outside, there is still a slight trace of coconut fiber inside, which is similar in texture to the fiber in juteIt can be used instead of jute to make rope.
The rope can also be processed into fishing nets, which can be used by people in agriculture and fishing.
Coconut fiber is wear-resistant and waterproof, and can be processed into a variety of mats or carpets.
In addition to this, high-quality coconut shells can also be coveredProcessed into activated carbon。Coconut shell has strong wear resistance and strong adsorption performance, which has a great effect on removing peculiar smells and purifying industrial sewage.
India has a soft spot for the "treasure" of coconut shells, and because of its so many uses, India will take a large number of coconut shells from various countries.
Some people shy away from food that tastes。Like stinky tofu, snail flour, and durian, these are common smelly and fragrant foods in our lives.
Durian is also a tropical fruitIt is native to Malaysia, abundant in Thailand and other places, and is also cultivated in some parts of southern China.
Durian is known as the "King of Fruits".Durian meat is rich in vitamins, sugars, proteins, carbohydrates, amino acids, and more.
It's not that people don't want to eat such a nutritious fruit, one is because of itTasteIt's a bit frightening, and the second has to be itCause.
The growing environment of durian is demanding, and its growth cycle is also longIt takes about 8 years to produce ripe fruit.
The cost of manpower and material resources for planting is relatively high, and on the other hand, it also requires a certain cost to transport durian from foreign countries to meThe ** of durian is even higher.
In addition, durian is also more smellyIt contains sulfide itself and gives off a foul smell, the more ripe the flesh, the greater the effect of this sulfide and the more smelly the durian becomes.
What is the purpose of the hard and weird durian shell?
Can you think of a relationship between durian shells and band-aids?That's rightDurian shells can be made into a new type of Band-Aid.
Four scientists in Singapore conducted research on durian shells and found that durian shells can be processed into durian shellsDecomposable hydrogel cloth.
Adhesive tape is used on band-aids to prevent the invasion of external bacteria, which is more conducive to wound healing and can also reduce the protrusion of scars.
There is a lot of flesh in durian, but there are also a lot of excess durian shells left, and under normal circumstances, people will burn or bury these durian shellsDoing so will have an impact on the air.

It's the same with mangoes, there will be a lot of rotten mangoes in the marketIn most cases, such fruits are thrown away if they can't be sold.
Rotten mangoes can also be processed into leather.
Mango contains a lot of fiber, and after chemical additives and machine operation, the pulp becomes a sheet of reprocessable leather.
This leather is very wear-resistantEmbossed and patterned engravingand so on, which can be reprocessed into bags, leather shoes, and so on.
There are many things that can be reused, the most common in our lives is plastic bottles, plastic products are difficult to degrade, and the impact on the environment and land is reduced after secondary use, it is also a lot more convenient in our lives.
