Illustration. Powdered caterpillars are rich in protein The mealworm is a species of beetle in the family Tenebrionidae, known in English as Mealworms or mealworm beetle. In 1758, Linneus gave the scientific name Tenebio molitor. This species is native to Europe, is on the list of storehouse pests (cereals, flour and food), but is not serious. In Vietnam, mealworms are considered to originate from the Mediterranean, but are mainly imported from China through informal channels and considered as “strange weeds” (foreign creatures) with the name “Golden mealworms”. Powdery mildew larvae are widely sold in Hanoi and used as food for ornamental birds. Insects for animal and human food have received increasing attention in recent years. They may represent an alternative source of protein and micronutrients compared to conventional meat sources. Therefore, the objective of this work was to determine the nutritional value as well as the degree of chemical and microbiological contamination in order to better assess the risk/benefit of consuming mealybug larvae. These mealworm larvae have a nutritional value with 10.4% fat and 13.7% protein, similar to conventional meat sources. Their main fatty acids are oleic (37.8%) and linoleic (33.2%). The results showed that these larvae met the essential amino acid requirements (all above 100% of the daily contribution), with the exception of lysine. Study results also show that T. monitor larvae are an excellent source of minerals such as phosphorus, magnesium and zinc (114%, 109 to 128% and 117% of the RDI). Although, it is low in potassium and iron (16-17% and 20% of the RDI). The lower sodium content is a health advantage, as eating a lot raises blood pressure. The mercury and lead values ​​were below the detection limit and the cadmium level was 0.10 mg/kg. The larvae of mealybugs had a high amount of bacteria but no pathogenic bacteria were detected. Starving the larvae for 8 days at 5°C reduced the total number of microorganisms, especially yeast, and the total number of thermophilic anaerobic spore forming bacteria. Licensed by Europe as food Recently, the European Union Food Safety Authority (EFSA) announced that it has granted a safety certificate for the consumption of dried yellow powder worms. It paved the way for restaurants in the area to offer insect-based foods. The EFSA’s first approval of a food insect is a big step forward in helping insects find a “place” in the daily menu of people. This is the basis for EU officials to decide whether to allow the sale of this item in 27 countries in the region. The new decision also marks the first time the safety assessment process for an insect food has been completed by EFSA, as the agency aims to license the protein-rich food industry. Currently, in Europe, insects are still not on people’s menus. Because of psychological and cultural issues, different from the reality in some Asian countries such as Thailand, Cambodia, Vietnam, Hong Kong, China… However, with this decision, the industry expects the insect food market in Europe to grow rapidly in the coming years, reaching an output of 260,000 tons by 2030. Not only flour worms, rice worms (Zophobas morio) will probably not be far away from taking over all nutritious foods such as chicken, beef, pork, milk… to become the main source of protein for mankind. Future. Rice worm farming accounts for only 10% of the land area compared to cows, 30% of the area is for pig farming, 40% of the area is for chickens. Meanwhile, the level of protein supply of this worm is as high as that of the foods mentioned above. In Vietnam, although mealworms are only raised to serve ornamental birds, other insects such as crickets, ca cuong, chits, bamboo worms, black thorn ants… have been bred or exploited in the wild for trading. sold for human consumption. Other benefits Research results from Stanford University have informed the miraculous ability of mealworms. That is, they can eat foam plastics and other forms of polystyrene. There are some insects capable of degrading plastic such as the wax worm Achroia grisella and Galleria mellonella or the Mediterranean moth (Plodia interpuncella)… that can chew, eat and digest plastic as garbage bags. In the intestines of mealworms, there are many species of microorganisms capable of degrading polyethylene (PE). 100 mealworms are capable of consuming 34 – 39 milligrams of foam insulation, equivalent to the weight of a capsule per day. Larvae that eat all foam insulation are just as healthy as those that eat bran. The mealworm converts plastic into CO2, biomass and waste that can be broken down by bacteria. This waste appears to be safe to use as fertilizer for plants. They have designed a breeding area for mealworms with three purposes: Decompose plastic, provide food for people and use waste to make fertilizer for plants. The breeding area for powdered worms is made from organic glass (plexiglass) and is designed to be divided into 4 floors. The adults (male and female) will be kept on the top floor. Their eggs, when laid, will fall through small holes to the second floor. Here, the eggs will hatch into larvae and be fed sponge. As the mealworms grow, they are moved to the third lower floor. Here they are fed powder to cleanse their intestines and pupate. The mealworm droppings on the third floor will fall on the fourth floor and be collected to be used as fertilizer. At the third floor, we can collect the mealworms for food or let them grow into adults and then bring them back to the top first floor to continue the breeding cycle. Farms that raise mealyworm larvae can produce more edible protein than traditional farms that raise chickens, cows, pigs or dairy cows for the same amount of land used. The researchers compared the environmental impacts of a mealworm farm with that of traditional livestock farms using three parameters. These are land use, energy demand and greenhouse gas emissions. They found that for each unit of edible protein produced, worm farms required much less land and energy.

1. Corn cob In the 1700s, Native Americans often used dried corncobs as ‘toilet paper’. This material is quite abundant, rich and soft, easy to absorb. Although the user may be a little sore, it is still considered safer and more comfortable than many other materials. 2. Snow For people living in cold areas, snow was a good candidate in a time when toilet paper wasn’t available. The only downside is probably the feeling of cold to the bone, but if you get used to it, no one will feel embarrassed because it is very clean. 3. Rocks It sounds unbelievable, but there were times when people used stones for cleaning. The advantage of this type of “toilet paper” is that it is easy to find, abundant. Just like the cob, although this is not the most comfortable material, it is at least very convenient when there is no other better material to replace it. 4. Wooden stick About 2000 years ago, people in ancient China used toilet sticks. This “toilet paper” is cut from bamboo and other woods, shaped like spoons. People call this tool salaka, cachou or chugi. The ends of the tools are covered with cloth to create a more comfortable feeling for the user. Even so, it still makes people shudder just thinking about it. 5. Broken ceramic shards Compared to the Chinese, the Greeks have even more creepy “toilet paper”. In ancient toilets, the Greeks used “pessoi” (small pieces of pottery) to clean after defecation. These ceramic pieces, usually 3-11 cm in diameter, are cut and angled from broken pottery. This material is so popular that the Greeks have an adage: “Three pieces are enough to wipe”. 6. Tersorium If the above materials are too hard and easily cause pain to the user, the Roman tersorium seems more comfortable. Tersorium is a cleaning device created by attaching sponges to a stick. Although there is no specific document on how to use it, many people think it is likely that tersorium is a toilet brush and not “toilet paper”. 7. Mussel shell People in the island and coastal areas often make use of natural resources as an alternative to “toilet paper”, despite the fact that they have many sharp edges. If there is no mussel shell, people will replace it with coconut shell. 8. Grass Grass and leaves are the softest method ever used by man in history. The advantage of this natural material is that it is easy to find, environmentally friendly and convenient. 9. Sand Different climatic conditions lead to different cleaning methods. In arid places, people are forced to use sand to replace toilet paper. This way is not very comfortable but is almost the only option for many people.

An old Galaxy phone is used as a sensor for the sound of a baby crying. Photo: Samsung Through the SmartThings app, users can convert the function of Samsung Galaxy phones from 2018 and earlier into sound sensors to notify when they hear a knock on the door or the sound of a baby crying. Light sensors, which are used to adjust screen brightness, can be used to automatically control indoor lighting. Samsung also said that the battery of the old phone will be optimized to increase the uptime when the device has a new “life”. Innovative reuse is a method of reducing technology waste that is still relatively new compared to traditional ways such as giving away, returning the company or reselling. With this project, technology brands from Korea are expected to contribute to encouraging users to take advantage of old smartphones in everyday life, and help promote more of its technology ecosystem. Even so, according to technology site Ars Technica, despite its good environmentalism, the Upcycle program only allows the reuse of light and sound sensors. In fact, spontaneously, users have been devising many initiatives to reuse old phones, such as converting them into security cameras, data storage hard drives or music players.
