Workers collect garbage in the quarantine area. Photo: CTC Worried waste collection workers Due to the outbreak of COVID-19 epidemic, garbage collectors are very concerned because the waste source has the potential to contain pathogens, especially in isolation and blockade areas. However, due to the nature of their work, environmental sanitation workers still have to perform this task. According to Mr. Tran Van Toan (environmental sanitation worker of Ho Chi Minh City Urban Environment Company Limited): “The COVID-19 epidemic broke out, we felt very worried, the nature of our work had to continue. come in contact with a lot of waste and can’t tell which ones contain pathogens. However, we are fully equipped with protective equipment and strictly adhere to epidemic prevention and control, so we are somewhat reassured.” Agreeing, Ms. PTT (a garbage collector in Tan Phu district) shared: “With the current epidemic situation, many people don’t even dare to go out, let alone access the isolation and collection areas. garbage, because it’s really hard to know where there are infected people. However, sanitation workers like us, if they don’t do it, they won’t have a source of income to take care of their families. We hope that we will be given priority to vaccinate against COVID-19 to help alleviate some worries.” There is a risk of disease transmission from medical waste Ho Chi Minh City Urban Environment Company Limited (CITENCO) is the unit that collects and transports medical waste and waste at hospitals, isolation areas for treatment of COVID-19 patients in Ho Chi Minh City. and isolation areas, blockade areas established under the decision of the People’s Committees of districts in the city. According to experts, in isolated and isolated areas, the waste that is often at risk of infection is hazardous medical waste. For workers who collect, transport and process this type of waste, there is also a high risk of infection. Prof. Dr. Nguyen Huu Dung, Chairman of the Vietnam Built Environment Association, commented: The collection, transportation and treatment of waste in isolation areas, field hospitals and COVID-19 patients’ blockade It is necessary to strictly follow the instructions and regulations on environmental safety and hygiene. Sanitation workers who collect and transport this type of waste, if not properly protected, are likely to be infected with disease. “The waste in the isolation area, this field hospital is mixed with household waste and medical waste, including hazardous waste such as bandages, medicine, patient waste… Especially, viruses. can be transmitted in the air and remain on the surface of the object for a certain time,” Dung said. Also according to Prof. Dr. Nguyen Huu Dung, environmental sanitation workers who collect, transport and process various types of waste are very susceptible to exposure. Therefore, they need to be equipped with safe and appropriate working tools, and should enjoy appropriate protection and remuneration. “In my opinion, first of all, they should be given priority to get vaccinated against COVID-19 to prevent disease,” said Dr. Proposal to prioritize vaccination for garbage collectors According to a representative of CITENCO, currently all medical waste in hospitals, centers and polyclinics is collected and treated by the company according to the strict process of hazardous waste. During the outbreak of COVID-19, the company was directed by the People’s Committee of Ho Chi Minh City to be in charge of collecting domestic waste in the isolation area for patients infected with COVID-19. To ensure the safety of workers during the process of collecting, transporting and treating wastes that may contain COVID-19, CITENCO proposes to the City People’s Committee and the Department of Health to give priority to public officials and employees. The company is participating in the collection and transportation of waste vaccinated against COVID-19 as soon as possible. “The recommended vaccination cases include the staff directly managing and directing the company’s epidemic prevention and control; workers and drivers who directly collect, transport and treat wastes that may contain COVID-19, medical waste, domestic waste, and cremation; workers often come into contact with people,” said the representative. In Hanoi, Mr. Nguyen Huu Tien, General Director of Hanoi Urban Environment One Member Limited Liability Company (URENCO), also said: The company has sent a written request to the Hanoi People’s Committee, the Steering Committee for COVID-19 prevention and control. The Hanoi Department of Health considers and creates favorable conditions for the company’s officers and employees to be given priority to vaccinate against COVID-19. Hazardous waste is strictly handled According to CITENCO, the collection, transportation and treatment of medical waste are carried out by the company according to a very strict process, ensuring the safety of workers and preventing the spread of disease to the outside. The workers are equipped with protective gear that meets the standards of the medical industry. Accordingly, the waste is sealed in a special yellow container or bag, labeled with a warning of the risk of infection. Garbage before being collected to put on specialized transport vehicles (closed containers) is sprayed with disinfectant. Waste when transported to Dong Thanh waste treatment site (Hoc Mon district) continues to spray disinfectant again before being processed by high-temperature combustion technology. After burning, waste must be solidified and buried in a safe landfill dedicated to hazardous waste.

Therefore, in order to control plastic waste, Ho Chi Minh City has launched a plan to strengthen the management, reuse, recycling, treatment and reduction of plastic waste in HCMC. Prioritize recycling of plastic waste One of the solutions to reduce plastic waste is to organize the classification, collection, reuse, recycling and treatment of plastic waste. Accordingly, Ho Chi Minh City will promote the classification of domestic solid waste at source in accordance with the direction and direction of the City People’s Committee. It also encourages the separation of waste at source for plastic waste separately from other types of waste. Thereby, helping to make reuse and recycling activities more profitable and economic. HCMC will promote the separation of domestic solid waste at source. Photo: CN In addition, Ho Chi Minh City encourages the classification of plastic waste mixed in domestic solid waste at transfer stations, or domestic solid waste treatment plants and prioritizes transferring plastic waste to recycling units. use, recycle function. In case plastic waste is no longer able to be reused or recycled, other appropriate and effective treatment solutions should be implemented. Ho Chi Minh City will also organize the implementation of technical solutions or movements and campaigns to collect solid waste, plastic waste in public places, vacant land, rivers, canals, canals… in the area. . In addition, mechanisms and policies will be developed to encourage, give incentives and support to organizations and individuals that collect, reuse and recycle plastic waste and for production facilities. recycled, environmentally friendly products to replace difficult-to-biodegrade plastic packaging and disposable plastic products, etc. Minimize the use of non-biodegradable packaging The habit of using single-use plastic and nylon bags may bring convenience to people, but it is a big polluter for the environment. Therefore, one of the plans of Ho Chi Minh City is to minimize and proceed to not use non-biodegradable plastic packaging, single-use plastic products in all daily activities of administrative agencies. the state, non-business units, unions, schools, medical facilities, people… in the city. In addition, the city will review and assess the current status of plastic waste generated in the area, thereby proposing appropriate and effective solutions in managing and minimizing plastic waste in the area. The city will also continue to mobilize and urge the system of supermarkets, trade centers, convenience stores, people’s markets … in the area to strive to fulfill the targets set by the city. Specifically, the system of supermarkets, commercial centers, markets, convenience stores, bookstores, etc. have forms of encouraging consumers to bring bags when shopping, limiting or not giving free plastic bags. for consumers. Towards charging for bags and packaging of goods for consumers who need to use them when they do not bring bags when shopping… Convenience stores, food stores… have a discount policy, accumulate points for customers who bring products to store, store goods, food, drinks… Strengthening handling of the act of dumping plastic waste in public places Ho Chi Minh City will inspect and handle violations of environmental hygiene, indiscriminately disposing of waste and plastic waste in public places in the area according to regulations. At the same time, inspect and handle violations of environmental protection lease, value-added tax, corporate income tax… in the activities of importing, manufacturing, distributing, and trading in packaging. non-biodegradable plastic and disposable plastic products, recycled products, environmentally friendly and activities to reuse and recycle plastic waste in the city.

Design of a waste treatment line for the Vietnamese market with 3D technology at the Belgian company Menart. His work is part of the waste treatment project to make compost at the Residential and Industrial Solid Waste Treatment Area in Vinh Tan Commune, Vinh Cuu District, Dong Nai Province, which is carried out by Belgian company Menart and Co. Sonadezi Environment Joint Stock Company in Dong Nai province. Sharing with Vietnam News Agency correspondent in Belgium, Mr. Anthony said the design must be based on actual research and survey. He went to Vietnam and went to Dong Nai to review the field conditions at the place where the waste treatment plant will be built and then returned to Belgium, designed with 3D technology, the line will be installed to suit the conditions. Vietnam’s tropical climate. Some details are produced on-site by Menart company, others are sent to Vietnam for partners to do. The equipment will then be transported from Belgium to be assembled at a waste treatment plant for operation. Meanwhile, at the factory, Menart’s engineers are installing and testing waste sorting and composting equipment. This is the second production line that Menart is about to hand over to Sonadezi for deployment in Vietnam. In the equipment factory of the domestic waste treatment line of Menart Company, Belgium. Mr. Mot, an experienced technician, said that last year, he was sent by the company to Vietnam and to Dong Nai to prepare for the trial operation of the waste treatment plant. He stayed in Dong Nai for 6 months, with Vietnamese colleagues installing lines and training operators to prepare for the trial run of the plant in November 2020.

The 7.1-hectare plant was put into trial operation late last year with a capacity of 450 tons/day, operating 8 hours/day. The operation process consists of 4 main stages: waste sorting, aerobic composting, ripening, and creating refined humus. About 80% of the organic waste received will be treated as compost; about 15% of inert waste after burning is buried in hygienic burial pits; About 5% of nylon bags are recovered, recycled and reused. Currently, Menart continues to complete the garbage sorting equipment, composting machines, rotary machines, and composting equipment to hand over to Sonadezi to serve the expansion of the Vinh Tan waste treatment plant. Ms. Bérengère Menart strongly believes in the prospect of cooperation in this field with Vietnam. She said: “Vietnamese people and local authorities will raise awareness of environmental protection, reduce the amount of untreated waste into the environment and thus contribute to improving the quality of life.” She affirmed and wished to continue expanding cooperation in technology transfer to Vietnamese partners in the fields of environment and agriculture. With projects implemented in Vietnam, Menart is contributing to the local government to solve the management and treatment of waste, a hot issue today, due to the rapid urbanization process.

Ho Chi Minh City changed the way of classifying garbage into two groups. Photo: NGUYEN CHAU According to previous regulations, individuals, households, and solid waste source owners must be classified into three groups: Group of easy-to-biodegradable organic waste (leftovers, leaves, vegetables, fruits, animal carcasses. ); group of reusable and recyclable wastes (paper, plastic, metal, rubber, nylon, glass) and the remaining group of wastes (excluding hazardous waste generated from households, owners waste sources). To match the current treatment technology that focuses on recycling technology and incineration technology, Ho Chi Minh City has decided to amend the way of classifying garbage into two groups. Specifically, the group of wastes capable of reuse, recycling and the remaining group of wastes (excluding hazardous waste generated from households, waste generators. In the past, the city’s waste treatment was mainly landfilled. Part of MSW is treated by incineration (without energy recovery), fertilizer production and recycling. However, this is still limited and has not met the needs of the city.

Last spring, while consumers were concerned about how to clean themselves after defecating, scientists discovered that people infected with the Covid-19 virus shed the virus’s genetic material in their feces. surname. The waste treatment system for more than 100 years is too old In fact, toilet systems play a part in maintaining public health. However, the core technology in the toilet system has existed for more than 100 years, when humanity has not faced the current challenges. On top of that, many parts and equipment in the ground are reaching their lifespan and starting to fail due to lack of investment in maintenance. This year, the American Association of Civil Engineers scored D + for the country’s wastewater treatment infrastructure. Accordingly, there is too much waste around, this creates a potential danger to public health and the environment. The waste treatment system for more than 100 years is too old. Illustration. According to the Wired , evidence of the deteriorating waste disposal system existing around human habitats. While considered a flawed design, combined sewer systems are still prevalent in many older cities. Sewage water overflows when it rains, releasing potential pathogens into the waterways; Waste, nutrients, chemicals and pharmaceuticals get into the sewer system. Degraded septic tanks pollute the soil and groundwater. Wet wipes and other types of waste have tended to increase sharply since the outbreak of a pandemic, causing heavy congestion that keeps wastewater from flowing. Natural disasters caused by climate change overwhelm drainage systems. During the past year, massive floods from Tennessee to Australia left people inundated with polluted wastewater. In August, a series of power outages during a massive heatwave in California caused a wastewater treatment plant to dump nearly 189,270 liters of raw and partially treated wastewater into the mouth of the Oakland River. In February 2021, Texas weather continued to be cold, people could not bathe and heat for many days; a hospital truck dumped water just to flush the toilet. Prisoners endured the filthy days of prisons in Texas. Serious health effects Conventional wastewater treatment systems are not only degraded, but are also in short supply. More than half of the world’s population is not equipped with safe toilets to dispose of waste. According to the statistics of US Water Alliance It is estimated that 2 million Americans do not have complete plumbing, directly affecting health causing skin diseases such as rashes, intestinal diseases such as diarrhea, hookworm … and many difficulties. another towel. Ms. Pamela Rush, an activist from the Alabama countryside, shared her story about daily living next to the raw wastewater dumps, like many other poor people in America, mostly leather. black. These people are sometimes fined and criminally prosecuted for not being able to pay the costs of a septic tank or maintenance. Not being equipped with complete plumbing can directly cause skin diseases such as a rash. Illustration. More tragic, Ms. Pamela also became one of the victims of the Covid-19 pandemic. “The main cause of death was the corona virus, but the underlying causes she suffered were poverty, habitat inequality, climate change, racism and disparity. about health, “said Catherine Coleman Flowers, environmental equity activist. Catherine is also a friend of Ms. Pamela. For people who don’t have their own toilets, closing orders make public toilets harder to find than usual. This problem affects homeless people, people with intestinal disorders and other diseases. In some slums in developing cities, shared toilets are often open, but the order of social exclusion unintentionally makes matters more difficult than ever. Not only is wastewater treatment infrastructure deteriorating or facing many risks, so is the workforce. In the US, this sector is facing a wave of retirement, even seen as the “silver tsunami”. When the pandemic first started, some wastewater treatment industries feared losing old workers that were difficult to replace and important because of illness or worse. They have closed facilities with workers working week-long shifts so that the virus cannot enter. In India, sewer cleaners petitioned the government for simple personal protective equipment so they could keep working. Solution According to the Wired , to solve the problem of waste, the rebuilding of infrastructure is not enough, but it is necessary to apply many new innovations, encouraging the application of new methods. This helps the toilet system work better, ensures safety for human health, is more durable and reasonable. In order to do this, the state and local governments need to have enough funds and new public works policies to create incentives for improvement. Then, in places with stable centralized infrastructure, cities can use both new and established tools to mine wastewater for heat, water, nutrients, chemicals, and metals. valuable, as well as biogas and other fuels. Digital sensors help smarter sewage treatment systems using pipes and reduce spills. The new setup can push used toilet paper out of the wastewater stream before being processed and recycled into cellulose. This substance is a raw material that can be widely used, even used for industrial chemicals. With the right tools, even large chunks of trash that clog drains can turn into biofuel thanks to the greasy layers inside. Besides, there are many new and more radical inventions for the pipeline. Scattered distribution systems for toilet waste and water reuse in buildings or communities are rapidly developing. Businesses, cleaning services by container trucks provide regular cleaning services. A row of public toilets in South Africa. Photo: Alamy Stock Photo. “Urine divert” toilets help separate high-nutrient, low-pathogens from feces and water. They function more like recycling bins than trash cans. These innovations are more relevant in harsh contexts and are better resilient to serious consequences. They minimize the impact on the climate, cause less pollution and produce resources such as clean water, compost, fuel, even insect protein. They can generate revenue streams and provide safe, well-paid, and well-paid jobs that attract young people who are environmentally conscious and work diverse. Many of the above ideas are in beta. To turn these ideas into practice on a larger scale, more investment and supportive policies from the state are needed, attracting people who are willing to overcome difficulties to apply innovative technologies early. toilet system. In addition, there are other innovations such as treatment of the genetic waste corona virus in human feces. Scientists around the world have been analyzing wastewater and providing feedback to public health professionals and policymakers on outbreaks, new trends and the impact of regulations. rules and restrictions. The innovators are also experimenting with new ideas for public toilets, making them more popular with everyone. In Pune, India, the idea of ​​building a reusable bus women’s public toilets, plus a boutique and small coffee shop, helps to reduce the cost of using a toilet. Some cities have implemented or are considering paying a small fee for cafes, restaurants and businesses to provide public toilets. Instead, businesses are advertised for free and are seen as implementing a public service. The Covid-19 pandemic showed a deeper insight into the toilet waste treatment system: This is not only technology but also a human prerogative. According to the Wired Investing in a drainage system not only helps to upgrade old systems and expand the quality of sanitation and safety for everyone, but also avoids further damage caused by disease outbreaks and environmental disasters. Future.

An old phosphorus mine in Florida.

According to information from the BBC, China uses rare earths as a trump card in the trade war with the US. China has signaled that it could limit exports of rare earth minerals to the US as the trade conflict between the two countries escalates.

By far, China is the largest producer of raw materials vital to many US industries including high-growth industries such as electric vehicles and wind turbine manufacturing. The US Geological Survey has determined these minerals are very important to the economy and defense of this country.

Restricting exports to the US, if implemented, could have a major impact on major US industries worth trillions of dollars that rely on rare earth minerals.

Rare earths are a valuable resource that plays an important role in the industry.

Rare earth is a group of 17 elements used in many fields, including renewable energy technology, oil refining, electronics, … Called “rare” because they are difficult to exploit. This raw material is believed to be in the Earth’s crust. There are very few places in the world that exploit or produce rare earths because rare earth exploitation is both difficult and potentially harmful to the environment.

Rare earth exploitation is very difficult and poses a risk to the environment.

Currently, Chinese mines account for about 70% of global rare earth production. Myanmar, Australia, the US and some other countries only exploit a small amount, accounting for the remaining 30%.

According to US government data, about 80% of imported rare earths come from China. Estonia, France and Japan also supply treated rare earths to the US, but the original ore is from China.

The US mines rare earths and sends ore to China for processing, but China has imposed a 25% import tax. Consequently, the United States considered developing its own rare earth refining industry.

Information from the New York Times and Bloomberg said that the US is seeing the potential to exploit rare earth from old phosphorus mines in Florida. The process of handling leaked waste here helps to protect the environment and is an opportunity to reduce dependence on rare earths from China.

China is holding back most of the world’s rare earth supply.

A sewage leak at an old phosphorus mine in Florida prompted authorities to issue an evacuation order and declare a state of emergency near the Tampa area amid a potential collapse of the mine’s radioactive waste. Cleaning up the forgotten giant pile of phosphorus scattered in Florida and other parts of the southeastern United States could help resolve America’s dependence on important imported raw materials, while eliminating Threats of environmental disaster are lurking in the local people.

Phosphorus is a byproduct of the production of fertilizers from phosphate rock. For every ton of organic phosphoric acid produced, more than five tons of phosphorus are produced. This waste is worthless in its raw form due to the concentration of uranium, radium and other heavy metals making it radioactive toxic, unable to be used as soil amendment or building material.

According to the study, there is a large amount of rare earths and radioactive metals present in phosphorus piles in Florida. However, those are not the only scarce metals that can be found in phosphorus ores. Rare earths are a collection of elements that are important for high-tech applications such as magnets and lasers. A 2017 analysis by the US-China research group showed that rare earths are present at a rate of about 0.2% in a waste pile of about 1 billion tons in Florida, equivalent to two million tons of rare earths, enough to cover global demand for a decade.

Many laboratory studies have been done to look at phosphorus recycling processes. However, prices for phosphorus, rare earths and uranium have been mostly curbed in recent years to limit the commercial appeal of phosphorus recycling around the world.

Every year, the US government spends a substantial amount of money monitoring and managing risks at the old phosphorus mine in Florida. The US plans to spend about $ 111 billion to clean water pipes and water infrastructure.

Under the Donald Trump administration last year, the US environmental protection agency authorized the use of raw phosphorus as road construction materials. However, the cost of waste treatment here is so high that investors are still afraid.

The US government has to spend a lot of money on the treatment of the phosphorus mine in Florida.

Huge open-pit ponds the size of the entire city block, filled with toxic wastewater, and underneath there is a lot of radioactive waste.

Recently, local officials allowed residents to return home after an urgent effort to pump millions of gallons of water out of ponds and into inland waterways. The environmental impacts of releasing large amounts of polluted water have not been evaluated. But in the past week, the “ghost” of a great cataclysm caused the government to evacuate hundreds of households from the dangerous area.

Researchers fear that, when giant puddles collapsed, radioactive waste will leak, it will lead to unpredictable dangers. The environment will be affected by the emergency discharge of polluted water, which contains many substances that can cause harmful algae to bloom and kill fish.

Wastewater in the area near Wilmington in North Carolina.

Florida is considered the largest producer of phosphorus in the world, accounting for about 80% of phosphorus mining in the US – where the exploitation and consumption of about 23 million tons of phosphorus per year.

When coal-fired power plants generate electricity, they leave hundreds of thousands of tons of toxic sediment known as coal ash, mixed with water and dumped into ponds within the plant.

Across the United States there are more than 700 landfills and large bodies of water still store coal ash discharged from coal-fired power plants. Under the Obama administration, there were regulations to close coal ash ponds in 2018. Currently, the North Carolina region authorities also began requiring power companies to dig coal ash ponds under the new law. state, also requiring the closure of all coal ash ponds by 2029./.

The scene of the training class.

Vice Chairman of Dong Da District People’s Committee Ha Anh Tuan said that the goal of the training course is that the domestic waste step by step is classified according to the criteria of 3R (3R = Reduce, recycle and recycle). use (Reuse)); disposing of trash on time, at the right place; continue to maintain 100% daily waste collection; proceed to no garbage on the street, promptly collect garbage generated at all times of the day.

At the same time, strengthen the county’s State management over medical and hazardous waste disposal; adheres to the provisions of Joint Circular 58/2015 / TTLT-BYT-BTNMT on medical waste management, issued by the Minister of Health – Ministry of Natural Resources and Environment, and has performed well the tasks assigned by the City People’s Committee. approved in the project “Hazardous medical waste treatment in Hanoi to 2020, with an orientation to 2025”.

The Vice Chairman of the People’s Committee of Dong Da district also said that the district strives for domestic waste: Sorting over 70% of domestic waste. Reduce the average amount of waste 1.08 kg of waste / person / day to less than 1 kg of waste / person / day (down 7-8%). Guaranteed to collect 100% of daily domestic waste. 100% of people dump their trash on time and at the right place. 50% reduction in the number of manual collection trucks that collect rubbish in the alleys to replace them with motorized ones. 100% of means of transportation and garbage collection are fully inspected, maintained, maintained, and cleaned regularly, to ensure technical requirements (tight, not leak water and garbage vapor).

As for medical and hazardous wastes: 100% of medical and hazardous wastes are collected, transported and handled in accordance with the technical process and standards. 100% of medical facilities under the management of the district invested in completing the medical waste and hazardous waste classification system to ensure the standards and technical requirements as prescribed. 100% of small businesses and production establishments have measures to treat hazardous wastes such as motor oil, detergent, heavy metals, wastewater …

His rabbit farm started operating from December 2019. Mr. Hai analyzed: Rabbit meat is delicious and nutritious, processed many attractive dishes, is one of the foods that are currently favored by many consumers and the market …

Mr. Hai’s rabbit farm has a regular scale of 6,000 animals and is well-invested. Photo: Nhu Cuong.

His barn is about a few hundred meters from his house, on an area of ​​300 square meters of tender land during a period of 50 years. The cage is built in a closed and sustainable way with the entire iron frame, anti-heat roof, and a bright glass window system.

He designed and built a cage with 6 rows of compartments to separate mother rabbits, meat rabbits, breeding rabbits to suit breeding and care. The barn is fitted with LED lighting system, consumes 1500-2000 kW / month, 3 cooling fans with a capacity of 0.4W – 2.2 kW / month, and security camera system.

Water is taken from the family drilled well to clean the barn, clean filtered water to ensure the rabbits drink every day. To avoid environmental pollution and disease prevention, he uses a bioga gas tank to treat liquid waste, daily solid waste is collected to fertilize plants at home.

As a livestock production facility, so the animal husbandry officer in the village and commune often comes to advise him on how to take care of and clean the environment to prevent epidemics, ensure product safety. rate.

The white rabbit he is raising belongs to a New Zealand hybrid rabbit that is purchased from a reputable breed with quality assurance. Rabbit food is biosafety pellets, ordered from reputable dealers inside and outside the district.

Mr. Hai shared: Time to feed rabbits twice a day in the morning and afternoon, but must be punctual. In addition, feed your rabbits with clean vegetables grown in the garden once a day in the afternoon. The mother rabbit is 28 – 32 days pregnant and needs careful care.

Each year, a mother rabbit breeds 6 litters, each batch from 6-8 children, however, it is necessary to choose 6 healthy animals for commercial farming. Breeding rabbits are produced mainly for breeding the next litter or to be sold to people in need.

To prevent epidemics, Mr. Hai implements a vaccination regime of 4 months, 1 time of vaccination, 1 month of 2 days of medicine to prevent rabbits from scabies and ringworm …

From raising to harvest time is about 4.5 – 5 months, each rabbit individual has an average weight of 2.3 – 2.5 kg / head, parent rabbits are 3.5 – 4 heavier, 0 kg / head; Average selling price is 100 thousand VND / kg, selling 80 thousand VND / kg.
