[Introduction of Scientific and Technological Achievements] EDM Environmentally Friendly Distributed Kitchen Waste Equipment and Biological Solutions
Garbage classification is an innovation of traditional extensive garbage collection and treatment methods. It is a scientific management system that effectively disposes of garbage, avoids environmental pollution, and promotes resource recycling. At present, China has upgraded garbage classification to a national system, and many places across the country, such as the North, Guangzhou and Shenzhen, have been legislated to promote. The Ministry of Housing and Urban-Rural Development's "Notice on Comprehensively Carrying out Domestic Waste Classification in Cities at and above the National Level" requires that by 2025, cities at and above the national level should basically build a waste classification and treatment system.
After garbage classification, perishable waste such as kitchen waste is decentralized, incremental, and the existing end-processing capacity is facing a large gap. The traditional centralized large-scale facilities have a long treatment chain and a large social investment burden. The use of local and nearby small facilities for kitchen waste disposal can effectively reduce the source of domestic waste, save social costs, and avoid secondary pollution. It is a solution to the problem of kitchen waste disposal. The new model of the problem has huge social demand.
The Institute of Applied Biotechnology and Equipment of our institute has been committed to the research and development and application of kitchen waste biodegradation technology for many years. This issue will take you to understand---EDM Environmentally Friendly Distributed Kitchen Waste Equipment and Biological SolutionsRight ~

science and technology research and development
Kitchen waste is a general term for household kitchen waste, kitchen waste and other kitchen waste. The main treatment methods of kitchen waste at home and abroad include large-scale centralized incineration, landfill, anaerobic digestion (biogas), and distributed small-scale kitchen waste disposal facilities.Distributed small facilities are in line with the characteristics of food waste dispersion, small footprint, small investment, source reduction to reduce the total cost of waste disposal, social and economic benefits are very significant, the market size has grown rapidly in recent years.
There are technical bottlenecks in the current small kitchen waste disposal facilities industry.
1. High energy consumption of electric auxiliary heat
The process route of medium and high temperature drying mainly reduces the dehydration and drying of kitchen waste by means of auxiliary heat such as electric heating, but the energy consumption is large and the processing cost is high, which is not in line with the social sustainable development direction of low carbon emission reduction.
2. Leachate treatment cost is high, sewage discharge is not up to standard
Due to the complex composition of kitchen waste and the influence of seasonal, regional eating habits and other factors fluctuate greatly, including drainage and water treatment needs of the route often have high sewage treatment costs, discharge substandard problems, and drainage network laying on the treatment site infrastructure requirements are high.
3. Insufficient reduction and low harmlessness
The degradation of perishable components in kitchen waste is not complete, which is easy to cause the treatment product to be corrupted again in a humid environment, thus causing secondary pollution, which does not meet the basic treatment requirements of complete harmlessness.
Innovative research and development of small modular, Internet of Things intelligent equipment has great social and economic benefits prospects.
science and technology innovation
EDM environment-friendly distributed kitchen waste equipment and biological solutions (Eco-friendly Distributed Microbial Food Waste Solution) is an innovative kitchen waste disposal scheme combining intelligent equipment and advanced microbial technology,Through intelligent equipment to accurately control the treatment process, play a microbial enzyme efficient degradation function, to achieve no auxiliary heat, zero drainage conditions of kitchen waste harmless, reduced treatment and resource utilization.
Technical advantages
1. No electric auxiliary heat energy saving and environmental protection
The use of microbial degradation of kitchen waste spontaneous heat to maintain the treatment process temperature, no auxiliary heat demand, low energy consumption.
2. No drainage, no leachate
Zero drainage throughout the treatment process, no pre-oil-water separation, no leachate generation, no secondary pollution risk, no infrastructure burden, flexible site selection.
3. No odor harmless thoroughly
The perishable components in kitchen waste are degraded by microbial bacteria and enzymes and converted into heat, carbon dioxide, water vapor and a small amount of solid biomass residue. The treatment process has no peculiar smell and the degradation products are safe and harmless.
4. Fast reduction speed and high reduction rate
The garbage generated on the same day is treated on the same day, and the degradation rate of 24-hour kitchen waste is ≥ 95%; The period of solid residue leaving the warehouse during normal operation of the equipment can reach more than one month, and the daily maintenance demand is low.
5. Intelligent IOT control is convenient
Equipment relies on the Internet of Things intelligent control system, data platform real-time monitoring, remote control, reduce operating labor costs.
6. Shorten the processing chain to reduce social costs
The source of local treatment to eliminate garbage removal, transfer links, significantly reduce social costs.
7. Resource utilization
A small amount of biomass solid residue as the final product can be used as raw material for organic fertilizer production and resource utilization.
8. Flexible for a wide range of scenarios
The equipment can be flexibly and modularly combined, with a small floor area (for example, the equipment covers an area of 7 ㎡ with a processing capacity of 200kg/day), which is suitable for local processing (<1 ton/day) in units of residential areas, government agencies and enterprises, and local processing (1 ton -50 ton/day) in units of parks, streets and other areas.
application value
market prospect
Research shows that with the annual increase in the output and treatment rate of kitchen waste in China, it is estimated that the annual investment in the kitchen waste treatment industry during the 14th five-year Plan period is 200-50 billion yuan, with a compound annual growth rate of about 15%, and the total investment scale can reach 180 billion yuan. As an effective way to deal with kitchen waste on the spot, distributed small-scale disposal facilities have grown rapidly in the industry in recent years. Taking Shanghai as an example, the Shanghai Municipal Administration of Greening and City Appearance plans that by 2025, nearly 3000 tons/day of kitchen waste will need to be treated through local and nearby small facilities, accounting for about 1/3 of the total kitchen waste treatment capacity.
Application areas
The concept of "EDM inside" supports enterprises in the industry to manufacture and operate equipment through technology. At present, the equipment of cooperative enterprises has been successfully applied to various scenes such as communities, airports, government agencies and enterprise canteens.
