When we eat fruits, we don't deliberately keep the skin or shell, and in our eyes, these shells end up in the trash can.
However, these husks are regarded as "sweet and sweet" by other countries, so what is the purpose of recycling them in large quantities? What else can such "garbage" do?
The grapefruit peel turns into yuzu sugar
Our common fruits with the outer skin, such as oranges, grapefruits, durians, and coconuts, we generally peel off the outer skin and go straight to the flesh inside.
For the folk, in the past, people might leave orange peels, dry the clean and not bad orange peels, and soak them in water to drink as a kind of tea, which is delicious.
Don't underestimate the grapefruit peel, which is actually very useful. The grapefruit peel has a strong fragrance, and people naturally want to stay with the fragrance.
Some people want to leave the grapefruit peel as a kind of aromatherapy and put it in the room to reduce the odor.
In fact, the inside of the grapefruit peel is white and soft, and it can actually be eaten after processing.
Remove the outermost orange peel, keep the white part, cut them into yuzu pieces, and wash them several times with water.
Boiled water and put it in cold water, wash it several times and pinch it dry, then put it in a pot, stir-fry it with a certain proportion of sugar and water, and the grapefruit is made with frosting on the outside.
This is the most popular practice, so what is the role of coconut shells, durian shells, and mangoes?
Coir
Coconuts are mostly grown in tropical areas with high temperature and rainfall, and are rarely planted in the south of the mainland, and India, Malaysia, the Philippines and other places are rich in coconut.
Coconuts grow on the tree, in the center of the tree top, in a clump of piles, most of the time, we are eating the flesh of the coconut and the juice inside.
For coconut-rich India, coconut can be used for a variety of purposes, coconut water and coconut meat can be sold to customers, and leftover 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 allegorical patterns are carved on the shell and placed as decorations 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 small amount of coconut fibre inside, which has a similar texture to the fibre in jute, which 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, high-quality coconut shells can also be processed 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 collects coconut shells in large quantities from various countries.
Durian shells
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 fruit, native to Malaysia, abundant in Thailand and other places, and also cultivated in parts of the southern part of the mainland.
Known as the "King of Fruits", durian meat is rich in vitamins, sugars, proteins, carbohydrates, amino acids and so on.
It's not that people don't want to eat such a nutritious fruit, first, because its taste is really a bit daunting, and secondly, because of its price.
The growing environment of durian is demanding, and it also has a long growth cycle, taking about 8 years to produce ripe fruits.
On the other hand, it also requires a certain cost to transport durian from foreign countries to China, and the price of durian is higher when combined.
In addition, durian is also more smelly, it itself contains sulfide that will emit a foul smell, the more ripe the pulp, the greater the effect of this sulfide, and the more smelly the durian is.
What is the purpose of the hard and weird durian shell?
Can you think that durian shells and band-aids can be related? Yes, durian 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 hydrogel cloth that can be decomposed.
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 shells, which will definitely have a certain impact on the air.
The processing of durian shells into adhesive tape reduces the burden on the environment and helps it play a role.
mango
Most of the time, people don't pick varieties or bad-looking fruits, because whole-grown fruits are more delicious.
The same is true for mangoes, there will be a lot of rotten mangoes in the market, and most of these fruits will be 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-resistant, and after embossing, pattern carving, etc., it can be processed into bags, leather shoes, etc.
epilogue
There are many things that can be reused, the most common in our lives is plastic bottles, plastic products are difficult to degrade, after the secondary use reduces the impact on the environment and land, our life is also a lot more convenient.
