Are there any health hazards associated with food waste?

What are the characteristics of kitchen waste.

1. High organic matter content.

The content of organic matter such as crude protein and crude fiber is high (each accounts for the sum of dry food waste and has a large development and utilization value, but it is perishable and produces foul odor.

2. There is a lot of water.

High water content, (water mass fraction greater than 80%), inconvenient collection and transportation, low calorific value, improper treatment is easy to produce secondary pollutants such as leachate.

3. Greasy. Oils (crude fats account for dry food waste and salt substances (sodium content is higher than that of other household waste, which has a greater impact on the quality of recycled products and needs to be properly disposed of.)

What are the health hazards of food waste?

Food waste can be a source of health hazards. Many of the pathogenic microorganisms in kitchen waste are often "delicacies" for mosquitoes, flies, and cockroaches. Mosquitoes inject saliva into the body through their bites**, which in turn transmit the germs to humans.

Flies and cockroaches can carry more germs, and cockroaches multiply very quickly. If there are elderly people, children, or people with allergies who have low immunity in the family, they are more likely to get sick if they come into contact with or eat these foods that have been contaminated by cockroaches and flies.

The moisture content of food waste is as high as 74%, which is very easy to ferment. If you don't throw away your food waste in time every day and store it overnight, it will pollute the indoor air.

The grease in kitchen waste is also the main part of "gutter oil". People experience headaches, vomiting, abdominal pain, and gastrointestinal discomfort after consumption.

When food waste decays, it can grow a large number of bacteria, germs and toxins.

are harmful and can act on fertilizer use.

Kitchen waste: leaves, leftovers, leftovers, fruit peels, eggshells, tea residues, bones.

1. First of all, the first type is some wilted or insect-eyed vegetable leaves when washing vegetables, that is, vegetable leaves that are not eaten and thrown away directly, which also belong to kitchen waste.

2. The second is that in the process of eating, the leftover meals, if these meals are thrown away, then this is kitchen waste.

3. When using some eggs or fruits, the peels or eggshells produced are kitchen waste.

4. Many people like to drink tea, and the remaining tea residue produced after drinking tea is also a kind of kitchen waste.

5. Some ribs or other bone things, the bones produced belong to kitchen waste, and these garbage are not allowed.

How to dispose of food waste.

For daily kitchen waste, we must first classify and dispose of it. Separate kitchen waste from other types of garbage, and sort and discard them at fixed points in the process of garbage disposal, so as to bring convenience to the subsequent treatment of kitchen waste. In addition, we can also reuse kitchen waste at home as much as possible, such as making eco-friendly enzymes from vegetable peels, and composting animal offal, fat, etc., to grow flowers and plants.

Restaurants, restaurants and other places can also reduce the storage capacity of kitchen waste and improve its utilization efficiency by purchasing special food waste shredders.

Kitchen waste includes leftovers, small bones, animal offal, tea residues, fruit shells and melon skins, plant residues, wilted flowers, waste cooking oil and other household garbage, which are easy to perish and produce foul odors, so they should be cleaned up in time.

There are many microorganisms in kitchen waste, but these food waste are the favorite of mosquitoes, flies, and cockroaches. Mosquitoes can inject venom into the human body by biting people** and spread germs to people; Flies and cockroaches are the same, they will carry a lot of germs, so where there are them, there are more germs, and they should be cleaned up in time; For the elderly and children with low immunity, or people with allergies, try not to contaminate food contaminated by cockroaches and flies to avoid getting sick after eating.

Food waste is harmful to the environment, and there are two ways to dispose of it, namely incineration and landfill. Kitchen waste is incinerated, which will produce a large number of harmful gases and pollute the atmosphere; The landfill method is easy to cause soil and groundwater pollution, so it should be treated according to the actual situation.

Kitchen waste refers to the garbage generated in residents' daily life and food processing, catering services, unit meals and other activities, including discarded leaves, leftovers, leftovers, peels, eggshells, tea residues, bones, etc., which are mainly home kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing.

Kitchen waste mainly includes:

Food residues such as leftovers, Western cakes, small bones, animal offal, tea residues, fruit shells and melon skins, plant residues and fallen leaves, withered flowers, waste cooking oil, etc.

Note: 1. The big stick bone is listed as other garbage due to its extreme difficulty in corrosion;

2. Kitchen waste not only refers to the food waste generated in the kitchen, but also includes biological waste such as dead branches and leaves that can be fermented and composted.

Benefits: Biotechnology on-site compost can produce tons of organic fertilizer per tonne.

The garbage generated in residents' daily life and food processing, catering services, unit meals and other activities, including discarded leaves, leftovers, leftovers, fruit peels, eggshells, tea residues, bones, etc., is mainly used in family 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. 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.

Disposal of kitchen waste should be provided to professional treatment units for treatment, it is strictly forbidden to use waste edible oils (including gutter oil) as edible oil after processing, it is strictly forbidden to directly use kitchen waste to raise livestock, poultry and fish, and it is strictly forbidden to produce fertilizer from kitchen waste without harmless treatment.

On April 27, 2020, when a reporter from the Beijing News visited Erlizhuang Community, Xueyuan Road Street, Haidian District, he saw that the kitchen waste recycling machine in the community was being piloted to convert kitchen waste into plant nutrient soil in the community, which not only met the needs of residents for planting flowers and plants at home, but also could be used for community landscaping.

It is understood that Xueyuan Road Street, Haidian District, took the lead in the pilot introduction of kitchen waste recycling all-in-one machine in the community's resident activity center, which effectively solved the bottleneck problem of community kitchen waste collection and transportation. It can process about 1,000 kilograms of kitchen waste every day, and convert about 100 kilograms of nutrient soil, which is used to reward community residents for garbage sorting work, forming a "green microcycle" within the community.

Vegetable leaves, melon and fruit peel shells, fish bones and fish bones, leftovers, tea residues, branches and leaves, seasonings, expired food.

Food waste is a kind of organic waste, including leftovers, leftovers, vegetable leaves, fruit peels, eggshells, tea residues, bones, shells, etc., which generally refers to the ** raw food and finished products (cooked food) or residues required in the family life diet.

Food waste can be used as compost for vegetables, fruits, or flowers.

Here are some guidelines for making fertilizer for your home:

Food waste composting is the process of using microorganisms and small insects in nature to break down organic matter (food waste) in the presence of air and water. The final product is called food waste fertilizer, which is rich in easy-to-use phytonutrients that form part of a healthy soil. It is recommended to buy a bucket and wooden box for composting food waste.

It is best made on the balcony or outdoors. When the food waste compost is fermented, it will have a taste (mainly ammonia and hydrogen sulfide).

Kitchen waste composting mainly has the following conditions: carbon-containing organic matter such as dried leaves, wood chips, paper, peanut shells, melon seed shells, etc. Nitrogen-containing organic matter such as fruit and vegetable waste, coffee grounds, malt powder, etc.

1. Air 2. Appropriate amount of water 3. Treat kitchen waste and turn waste into treasure.

Easy 6 Steps:

1. Separate edible kitchen waste (vegetable peels, fruit peels, a small amount of wasted cooked food) into containers.

2. Collect the dried organic matter (dried leaves, sawdust) in a small container.

3. Take a box or a bucket and drill 4 5 different holes around the container to let air in.

4. Spread a layer of soil on the bottom.

5. Now start adding food waste alternately wet waste (vegetable and fruit skins) and dry waste (straw, sawdust, dry leaves).

6. Cover this container with plastic sheeting or wooden planks to help retain moisture and heat. Some advice Every few days, use a rake to turn the pile quickly to provide inflation. If you feel that the pile is too dry, sprinkle it with some water and make it moist.

Within 2-3 months, your food waste should start to form compost on dry, dark brown soil. There are also ready-made, kitted tools for food waste composting. With time and a little patience, you might enjoy composting food waste.

It is not recommended to use leftover meat, bones, leftovers, leftovers, etc. from food waste.

By sorting, ** and composting, a family of four can reduce waste by 1,000 kg to less than 100 kg per year. Imagine that 90% of all the garbage in Chennai disappeared overnight, a clean green city – and it will help you start your composting journey.

Kitchen waste includes discarded leaves, leftovers, leftovers, fruit peels, eggshells, tea residues, bones, etc., which are mainly home kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing.

Kitchen waste includes: discarded leaves, leftovers, fruit peels, eggshells, tea residues, bones, etc.

Kitchen waste includes leftovers, fruit peels, and fallen leaves.

Leftovers, leftovers, leaves, peels, eggshells, tea residues, bones, shells.

Kitchen waste in the narrow sense is a kind of organic waste, which is divided into cooked kitchen waste, including leftovers, leftovers, and vegetable leaves; Raw kitchen waste includes fruit peels, eggshells, tea residues, bones, and shells; It generally refers to the ** raw food and finished products (cooked food) or residues required in the family life diet. However, kitchen waste in a broad sense also includes used chopsticks, food packaging materials, etc.

Dead leaves, scallops, peels, leftovers, eggshells, cabbage leaves.

Food waste is not necessarily the waste generated by kitchen power, but refers to the waste that is perishable and degradable. The garbage generated in residents' daily life and food processing, catering services, unit meals and other activities, including discarded leaves, leftovers, leftovers, fruit peels, eggshells, tea residues, bones, etc., is mainly used in family kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing.

Household flowers, household potted plant residues and leaf litter, etc.

1. The impact of household kitchen waste on the environment.

At present, the city's domestic waste production reaches 6,600 tons per day, of which the perishable organic matter content is about 3,865 tons per day, which is mainly the kitchen waste part of the residents' domestic waste. Kitchen waste is the main factor of domestic waste pollution in our city, which is manifested in the following aspects:

First, it pollutes the collection container, breeds bacteria, attracts insects and flies, produces odors, and the cleaning work is heavy;

Second, it is easy to cause sewage spillage along the way during transportation, pollute the road surface, and corrode the transportation equipment; the third is to reduce the calorific value of urban garbage and increase the cost of waste incineration; Fourth, a large amount of biogas and leachate are produced in the landfill process, of which biogas is 20 times more destructive to the atmospheric ozone layer than carbon dioxide, and the cost of leachate prevention and treatment is high; Fifth, it pollutes the plastics, paper and other components in domestic garbage, causing difficulties or impossibility.

2. The environmental benefits of using a kitchen waste (crushing) processor to process kitchen waste.

Eliminating odor pollution is conducive to maintaining a good environment indoors and communities;

Significantly reduce the amount of urban garbage collection, transportation and treatment, and reduce the traffic congestion caused by the increase in garbage trucks and the impact on the city's appearance;

Effectively reduce the moisture content of domestic waste, reduce the pollution and corrosion of municipal garbage on collection and transportation containers and vehicles, and avoid sewage dripping during the transportation of garbage trucks;

Extend the service life of landfills, improve the operational efficiency of incineration plants, and reduce environmental pollution;

Maximize the pollution of kitchen waste components to the most important components in the garbage, and promote the utilization of resources;

It can be used as a supporting facility for "classified collection" to provide a breakthrough for the continued in-depth development of "classified collection", so as to improve the level of garbage management in our city and enhance the image of the city.
