Catering waste refers to restaurants, hotels, canteens and other food and beverage leftovers, as well as back of the kitchen fruits and vegetables, meat, grease, pasta and other processing waste; food waste refers to the family daily life of fruits and vegetables and food waste, leftovers, fruit and vegetable peelings, such as perishable organic waste; both collectively referred to as kitchen waste.
Because of the dual attributes of kitchen waste with pollutants and resources, kitchen waste treatment will become the focus of the development of China's environmental protection industry, and kitchen resource technology will become the future development of China's environmental protection industry, technology research and development trends.
Despite the downturn in the food and beverage industry due to the epidemic, the amount of kitchen waste generated is still increasing
According to the National Bureau of Statistics, the national food and beverage revenues in 2019 will be 4.67 trillion, an increase of 44.6% over the 2015 figure of 3.23 trillion prior to the 13th Five-Year Plan. 44.6%, an average annual growth rate of 10%, it can be said that the "13th Five-Year Plan" during the catering industry has made very gratifying achievements. However, after the epidemic in 2020, China's catering consumer market has been seriously affected, the catering industry has become one of the most seriously damaged industries.
According to data released by the National Bureau of Statistics, in December 2020, catering revenue was 495 billion yuan, an increase of 0.4%, and in November it was a decline of 0.6%. 2020 full year, catering revenue was 3,952.7 billion yuan, a decline compared with 2019; above-limit catering revenue was 823.2 billion yuan, a year-on-year decline of 14.0%.
The outbreak of the new crown epidemic in early 2020 made China's dining business suffered a serious blow, and the epidemic has brought a huge change in people's lifestyles. However, despite the closure of restaurants and the closure of canteens in schools and companies leading to a decline in the amount of food waste generated, the amount of food waste generated from cooking at home increased;
But considering that the amount of food wasted from eating out is higher than the amount of surplus generated from cooking at home, the overall total amount of food waste generated in China in 2020 increased to 127.75 million tons, but the increase was lower than that in 2019, dropping slightly from 5.91% to 5.79%.In 2021, people's lives gradually return to normal, so the amount of food waste generated will continue to increase.
China is the world's best-controlled country by the epidemic, and by the end of 2020, the country's economic and industrial development has gradually recovered, and people's daily lives are on track. With the rapid development of China's "takeout" economy, assuming that China's food waste generation in the 2021-2026 period of the compound annual growth rate remains unchanged, that is, to maintain the 2015-2020 compound annual growth rate of 6.16%, China's food waste generation in 2021 grew to 135 million tons; 2026 China's kitchen waste generation can reach 180 million tons.
Research and development of efficient resource technology is the ultimate way to deal with the huge amount of kitchen waste
In the 2020 National People's Congress, the National People's Congress representatives have said in the proposal, the amount of kitchen waste generated is far more than expected, the end of the garbage classification is a key issue of the treatment of kitchen waste, and the search for new technologies and programs, is the The current response to the impact of the huge amount of kitchen waste after the classification of garbage is indispensable.
China's kitchen waste mainly includes food waste, paper, metal, bones, wood, fabrics, plastics and oil and grease, etc., of which the food portion accounts for 70%-90%, water content accounts for more than 70%, oil content of 1%-5%, organic matter accounted for more than 80% of the content of the dry matter, the crude protein accounted for about 15% of the mass of the dry matter, the carbon and nitrogen ratio is generally (10:1)-(30:1);< /p>
That is, kitchen waste has a high water content, high organic content, high oil and grease, high salt, easy to rot, a small amount of non-food impurities, etc., direct filling, incineration without effective treatment of kitchen waste will cause irreversible harm to the ecological environment, for example: landfill process will produce odor and greenhouse gases, leachate pollution of groundwater, etc.; Effective treatment of China's huge amount of kitchen waste in recent years is the The effective treatment of China's huge amount of food waste is a hot issue in China's environmental protection industry in recent years.
It is worth mentioning that, in the paper "Research and Prospect of Kitchen Waste Resource Utilization Technology" published by Nanjing University and Hong Kong Baptist University, it is found that there are certain differences in the nature of kitchen waste in different cities of China, the reason for which is likely to be related to the local living and dietary habits; therefore, in the process of resource utilization, the characteristics of the various components of the kitchen waste in different cities should be taken into account fully. The most suitable treatment method should be selected when choosing the waste treatment technology.
The huge amount of food waste generated every year is gradually challenging the bottom line of our landfills, and also creating a super load on the environment. In addition to the "hazardous" food waste also has the "resource" characteristics, proper treatment will produce good environmental and economic benefits;
So the appropriate green and sustainable food waste treatment method has become a difficult and hot issue. However, in the development of resource treatment technology, China's technology still has a lot of room for improvement.
At present, to reduce the waste treatment process to produce again the odor gas and wastewater and other pollutants is also the inevitable requirements of the technology to continue research and development; in addition, China should improve the stability of the operation of the waste treatment equipment, more research and development of kitchen waste resources with high conversion rate of the technology, for example: kitchen waste biorefinery production of high-value-added chemicals is the realization of the high value of the use of kitchen waste is an effective way to replace the traditional chemical routes to produce chemicals, but also an important An important path to replace the traditional chemical route to produce chemicals.
New Kitchen Waste Treatment Projects Increase Year by Year, Southwest Region May Become a Rising Star
In early April 2018-2021, China's disclosed new kitchen waste treatment projects in the pipeline are growing rapidly.In 2019, China has 22 new kitchen waste treatment projects in the pipeline, an increase of 5 items. Among them, the investment amount of some projects is as high as 1.2 billion yuan.In 2020, China's new food waste treatment projects in the pipeline are 24, an increase of 2 over 2019.
Because of the special circumstances of the epidemic in 2020, only comparing the situation in 2019 and 2021, January-April 2021, China's new food waste treatment projects in the pipeline have been 11, equivalent to have reached 50% of the new projects in the pipeline in 2019.
In 2021, China's new food waste treatment projects in the pipeline have been 11, which is equivalent to have reached 50% of the new projects in the pipeline in 2019.
By regional distribution, in January-April 2021, China has disclosed the new food waste treatment projects in the pipeline are mainly distributed in Central China and Southwest China, with the number of 7 projects, which together account for 43% of the country's new number.
From the distribution of new kitchen waste project construction in January-April 2021, Southwest of this market may become a gold-digging backwater in the late stage. This is due to, in 2020 the National People's Congress, the National People's Congress recommended, in the country's urban and rural areas to promote the distributed treatment of kitchen waste.
Including the development of policies to encourage and promote the use of miniaturized distributed kitchen waste treatment, the central financial investment in miniaturized distributed kitchen waste treatment site construction and operation to give some support. From this aspect to speculation, can also be found in the development of kitchen waste disposal of another trend, kitchen waste disposal market will sink to the third and fourth tier cities.
The overall development of Yunnan and Guizhou in the southwest region is slow, and the environmental protection industry is lagging behind the development of other economically developed cities. Recently, in the "14th Five-Year Plan" in the environmental protection chapter, the state clearly put forward 2025 to the widespread formation of green production and lifestyle, carbon emissions peaked after a steady decline in the ecological environment has fundamentally changed for the better, the construction of a beautiful China basically realized the goal; around this goal Sichuan, Yunnan and Guizhou announced the 14th Five-Year Plan outline on green environmental protection aspects
