What are the three major hazards of food waste? What is Food Waste? What are the main hazards?

What are the top 3 harms of deleting trash? Polluting the environment and polluting surface water is harmful to human health.

First of all, let's be clear, food waste and food waste are not the same kind of waste. Garbage can be divided into five categories: domestic garbage, kitchen waste, fruit and vegetable waste, garden waste and bulky garbage, of which domestic garbage can be divided into hazardous garbage, can be ** things, other garbage and kitchen waste, the characteristics of each type of garbage, ** and treatment methods are different, see Figure 1 for details.

Figure 1 Sorting and disposal of garbage.

Food waste is a type of garbage, mainly for the food residues, food processing wastes and waste gas edible oils and fats generated by relevant enterprises and public institutions in food processing, catering services, unit feeding and other activities, with large output, relatively concentrated quantity but wide distribution characteristics; Kitchen waste is a kind of domestic garbage, also known as wet garbage, perishable garbage, mainly for the daily life of residents, farmers' markets produced leftovers, melon and fruit peel shells, carrion bones and waste food, etc., with a huge number but relatively scattered, very perishable and deteriorating, emitting the characteristics of foul odor.

The hazards of food waste are as follows:

1. If the relevant departments are lax in management, food safety accidents are likely to occur. The gutter oil and saliva oil we often mention are actually a kind of kitchen waste. When the kitchen waste is not disposed of in a timely and non-standard manner, it is easy for illegal traders to take advantage of the opportunity to steal the gutter oil in the kitchen waste for profit.

2. The amount of kitchen waste is huge, relatively concentrated, and not treated in time, which not only emits a foul smell, but also attracts mosquitoes, cockroaches, mice, etc., which can easily lead to the spread of diseases and have a great impact on the health and normal life of nearby residents.

3. Food waste has high oil content, is perishable, and is not treated in time, which is easy to produce a large amount of toxic and harmful leachate and organic matter, damage the local soil and even groundwater, and seriously endanger the surrounding ecological environment.

Food waste is mainly the leftover food in the restaurant, including all kinds of oil and water, food residues because it is leftover food, so this thing is easy to expire, not only emitting peculiar smells, it is easier to breed bacteria, provoke mosquitoes, and at the same time, because of the water content, it is also easy to form leachate of garbage. Therefore, the treatment of food waste is very important, and improper disposal can easily become a hotbed for disease transmission.

In addition to these natural characteristics, there are also human factors, kitchen waste contains high oil and salt, and some illegal traders aim at this unconscionable money, illegal operations for profit, so that food safety things happen repeatedly, causing a series of social problems.

In short, food waste is an important source of pollution in the urban environment, and it is also a problem that environmental protection and development have to face.

Due to the characteristics of kitchen waste, the treatment of kitchen waste is different from ordinary domestic waste, not only in the process of storage and transportation, it is required to have good airtightness, in the process of treatment, the requirements for harmlessness are also higher, but from this point of view, although we have certain achievements, but there is still a lot of room for progress.

Definition: Food waste refers to "leftovers, expired food, scraps, waste and other wastes formed in the process of processing and consuming food in restaurants, hotels, canteens of enterprises and institutions, food processing plants, and households."

Hazard: kitchen waste organic matter content is high, the yield is large, the origin is scattered, it is easy to spoil and smell sour, breed harmful organisms, if the leakage occurs in the process of collection and transfer, it will pollute the air, soil and water sources, seriously interfere with people's normal life, and have a harmful side. In most parts of China, it is customary to feed food waste directly to livestock and poultry as cheap feed.

But in addition to containing metals, toothpicks and plastics and other sharp and hard objects can hurt the digestive tract of livestock and poultry, but also contains a large number of pathogenic microorganisms, parasites and their eggs, and it is easy to cause zoonotic diseases after feeding livestock and poultry. In addition, there are food chain hazards associated with direct feeding of food waste to livestock and poultry: first, the biotoxins produced by pathogenic microorganisms are enriched in livestock and poultry, and then transferred to the human body through the food chain; Second, kitchen waste contains a large number of homologous proteins fed to livestock and poultry, there are major safety hazards, such as the current general belief that mad cow disease (bovine spongiform encephalopathy) large-scale outbreak is mainly due to cattle eating mutton bone meal with sheep scrapie, so Canada, the United States, Japan, South Korea and the European Union and other countries have enacted legislation to strictly prohibit the use of ruminant protein to refine animal feed or the use of animal-derived protein feed to feed the same animal.

There are four major hazards of kitchen waste, especially the last one, which really affects each of us.

The first major hazard is the pollution of the environment, which affects the appearance of the city. Kitchen waste contains high levels of organic matter and water, which is easy to rot under the action of microorganisms, producing leachate and foul-smelling gases, which is easy to breed mosquitoes and attract flies, and has adverse effects on environmental hygiene.

Second, it endangers human health. Meat proteins and animal fats in kitchen waste are susceptible to homologous contamination of similar foods, leading to cross-infection of human and animal diseases, which seriously endangers our health.

Third, kitchen waste invades the surface and pollutes the water body. In the process of kitchen garbage stacking or landfilling, a large number of acid and alkali pollutants will be produced, destroying the vegetation on the earth's surface, not only affecting the beauty of the natural environment, but also destroying the natural ecological balance. In addition, the permeate enters the groundwater through the soil, which will affect the safety of our drinking water.

The fourth and most important hazard is serious impact on food safety. Everyone should know about gutter oil, right? Gutter oil is driven by windfall profits.

Some illegal businessmen illegally ** kitchen waste, through a series of simple processing, heating, filtration, distillation and other means to extract oil, and then sell it to some food processors, such as catering, seeking huge profits. Therefore, in order for our own health and that of our families to no longer be affected by gutter oil, please dispose of kitchen waste properly. Use oil-water separators and garbage disposals.

Infore environment is the only one in China to open up the whole industry chain of kitchen waste collection and transportation and end treatment of the whole industry chain of enterprises, as early as 2007, Infore environment of Zoomlion environment took the lead in setting up a targeted research center to explore the kitchen waste treatment equipment technology in line with China's national conditions; In 2015, Zoomlion Environment invested 57 million euros to acquire Italy's leading environmental and renewable energy all-round solution provider - Italian Ladurner (Nadurner), integrating its advanced European anaerobic and organic matter wastewater treatment technology and project operation and management experience, and launched the third generation of kitchen waste treatment technology and solutions as a whole, and in 2016, it achieved in-depth application in the self-invested construction and operation of Jiangsu Huai'an kitchen waste treatment project.

As the only enterprise in China with the development strength of the complete process chain of food waste treatment, Infore environment strictly achieves the equipment for the process and the system for the project, from the process to the equipment, from pretreatment to anaerobic to the whole wastewater system, and the equipment is required by the process, the system is used by the project, seamless connection, compatibility and matching, and the stable operation ability is leading in the industry.

What is it: To put it simply, food scraps generated by canteens, restaurants, hotels, etc. are all food waste.

Hazards: The first thing is the smell, the taste of organic matter decay and deterioration does not need to be said, the smell of meat, vegetables and something at home is what the smell is everyone understands, kitchen waste is not the same, a street restaurant can produce dozens of kilograms of kitchen waste a day, a large restaurant can produce hundreds of kilograms, a large enterprise canteen may produce half a ton of kitchen waste, so much garbage gathered in the first level of fermentation and corruption, the taste can be imagined.

The second is that snakes, insects, rats and ants are cheaper, which will provide abundant food for these harmful species**, leading to large-scale reproduction and spread of diseases.

There is also a good place for mosquitoes to breed.

Finally, there is the destruction of land and the impact on groundwater. The accumulation of a large amount of food waste will produce a large amount of garbage water seeping into the ground, resulting in groundwater pollution, and secondly, the oil and salt in the kitchen waste will destroy the soil properties and are difficult to recover.

Food waste is the leftovers that people eat, including the residues of crude processing of ingredients. These substances are highly perishable and can have a detrimental effect on environmental hygiene. In the process of collection, transportation and storage, if no airtight and harmless measures are taken, it is easy to cause food waste leakage, so that odorous gases and sewage are directly discharged into the surrounding environment, causing environmental pollution, disrupting the order of environmental sanitation management, and seriously affecting urban environmental sanitation.

Kitchen waste in a broad sense is mainly a general term for household kitchen waste, food waste and other kitchen waste. The kitchen waste referred to in the general domestic waste classification is household kitchen waste, which refers to the perishable garbage such as vegetable gangs, vegetable leaves, melon and fruit peel shells, leftovers, and waste food generated in the daily life of residents. Food waste refers to food residues, food processing fertilizers and waste oils and fats generated by relevant enterprises and public institutions in food processing, catering services, unit feeding and other activities.

Kitchen waste has the characteristics of wide range, large output, mixed sundries, and large water content. It can be treated by anaerobic biogas production, aerobic composting, biological protein technology, biological drying + incineration, pressing dehydration + incineration and other technologies.

Kitchen waste that is not properly collected, stored and transported is perishable, can easily cause cross-flow of sewage, emit foul odors, attract mosquitoes, spread diseases, and pollute air, soil and water sources. The direct mixing of kitchen waste with other waste in landfill will form leachate under high pressure and the action of microorganisms, which can easily cause secondary pollution to water sources and soil. The oil in kitchen waste is also the main source of "gutter oil", which is easy to be used by criminals and brings great harm to people's dietary health.

Kitchen waste is mainly used in family kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing. It refers to the garbage generated in daily life and food processing, catering services, unit meals and other activities, including discarded leaves, leftovers, leftovers, fruit peels, eggshells, tea residues, bones, etc., which are easily perishable and produce foul odors.

Kitchen waste is complex in composition and contains a large number of toxic and harmful substances, if it is directly used to feed animals without treatment, it will not be able to replace the invasion of toxic substances, and directly enter the human food chain, which will cause great harm to human health; Food waste that is not collected and disposed of in accordance with the regulations endangers the safety of municipal facilities and the safety of the water environment; "Water and oil" circulate into the market, bringing great hidden dangers to food hygiene and safety; Kitchen waste is directly used as pig feed, which seriously endangers human health; Under the action of microorganisms, it is easy to decay, produce leachate and foul-smelling gas, easily breed mosquitoes, attract flies, pollute the environment, and affect the appearance of the city.

Food waste includes: vegetable leaves, leftovers, leftovers, fruit peels, eggshells, etc.

Food waste, also known as kitchen waste, refers to the garbage generated in the daily life of residents and food processing, catering services, unit meals and other activities, which is mainly home kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing.

Food waste is high in moisture and organic matter, so it is easy to perish and produce foul odors. After proper treatment and processing, it can be converted into new resources, and the high organic content allows it to be used as fertilizer, feed, biogas for fuel or power generation after strict treatment, and the oil and fat part can be used to prepare biofuels.

Food waste. It has a significant duality of hazards and resources, and its characteristics can be summarized as follows:

1. High moisture content, up to 80%-95%.

2. High salt content, some areas contain chili pepper and acetic acid.

High. 3. High content of organic matter, protein, cellulose, starch, fat, etc.

4. Rich in nitrogen, phosphorus, potassium, calcium and various trace elements.

5. There are pathogenic bacteria and pathogenic microorganisms.

6. Perishable, deteriorated, smelly, and breeds mosquitoes.

1.Kitchen waste in the narrow sense includes: discarded leftovers, small bones, animal offal, tea residues, fruit shells, melon skins, eggshells, tea residues, bones, etc., these garbage are a kind of organic waste, which is mainly home kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing.

2.In addition, plant litter, wilted flowers, and discarded cooking oil are also kitchen waste, and the above are several types of kitchen waste that are easy to ignore.

3.Kitchen waste in a broad sense also includes: used chopsticks, food packaging materials, etc., which are also relatively common kitchen waste, pay attention to the difference between kitchen waste and kitchen waste in a narrow sense.

The main components of food waste include rice and flour food residues, vegetables, animal and vegetable oils, meat and bones, etc., and in terms of chemical composition, starch, cellulose, protein, lipids and inorganic salts.

Vegetable leaves, leftovers, leftovers, fruit peels, eggshells, tea residues, bones, coffee grounds, market meat and fruit and vegetable scraps, etc., are mainly home kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing. Food waste contains extremely high levels of moisture and organic matter, which can easily perish and produce foul odors.
