Kitchen Waste and Municipal Solid Waste-Separate Collection and Waste to Eco-energy
Dates:2017/11/20 Hit:1955
How to dispose municipal solid waste and kitchen waste? This has become a matter of high concern as economy, society, and cities develop. MSW and kitchen waste that surround us are major threats to sustainable development. As landfills in many cities are nearly filled up and establishment of new incineration plants faces more stringent requirement. Is there a third way out for reducing MSW and kitchen waste?
The Implementation Plan of the Municipal Solid Waste Separate Collection System issued by China’s National Development and Reform Commission (NDRC) and Ministry of Housing and Urban-Rural Development requires waste sorting in 46 cities in China and sets out that the recycling rate of MSW should reach more than 35% by 2020. How to dispose the separated waste? What are the technologies that are more suitable for China which can hardly realize thorough sorting?
Problems in waste treatment that China faces are exactly the ones appear in Germany thirty years ago. That’s why we shall learn from the Germany measures and technological solutions.
Jiangsu WELLE Environmental Co., Ltd, through persistent efforts and cooperation with partners in Germany, introduces the advanced German technology and develops the EMBT technology according to the features of Chinese waste. Now the EMBT technology has been successfully applied in China and other Asian regions to turn MSW and kitchen waste to resources.

1. Introduction to the EMBT Process
EMBT process is based on the principle that the sorted MSW and kitchen waste are mixtures of organics and combustibles. Through bio-hydrolysis, the organic matters that are bio-degradable are dissolved and acidified. The organic slurry and combustibles are then separated through the extruding dehydration process.
The slurry goes through anaerobic digestion and produces biogas used as bio-energy. The separated solid matters become high calorie fuel with moisture content of 40% and lower calorific value of 1600-2000kcal/kg. The calorific value can reach 3000-4000kcal/kg after bio-drying which reduces the moisture content to 10%, turning the materials into RDF fuel suitable to be used in cement kilns, power plants, and other industrial kilns, or used as energy through incineration or pyrolysis gasification.

2. Features of EMBT Process
Significant reduction and recycling of waste
Over 60% of materials weight reduction through bio-hydrolysis
Solids after bio-hydrolysis with moisture content of 40% and lower calorific value of 1600-2000kcal/kg
High-calorie RDF products after bio-drying with moisture content of 10% and lower calorific value of 3000-4000kcal/kg.
Simple and highly applicable pre-treatment process
High adaptability of the bio-hydrolysis reactors to the changing contents of waste
Simple sorting process in the pre-treatment stage
Suitable for poorly separated waste
Remarkable environmental ecological benefits
Reduction of chlorine in the RDF through bio-hydrolysis and sorting process
Products with even physical properties and high calorific value
Suitable for the control of combustion pollution and promoting the utilization of calorific value

3. Solutions for Kitchen Waste/MSW to Resources
Bio-hydrolysis+Waste to Energy
1.Simple, steady, and reliable process with high adaptability to materials and low operation cost
2.Significant waste reduction by over 50%
3.Bound water in the materials is transformed to free water and removed through EMBT process. Organic wastes with high moisture content are thus changed to high calorific value materials, remarkably reducing latent heat loss in vaporization of the incineration process and increase power generation.
4.Even materials and steady incineration easy for secondary pollution control

Bio-hydrolysis+Bio-drying+Industrial kilns (thermal power plant)
1.This is an ecological recycling method with indirect incineration that disposes wastes and realizes recycling in cement kiln, thermal power plant, and other industrial kilns
2.PVC and other chlorides are removed by sorting, enhancing the quality of RDF products.
3.Sorting is done according to different requirement of industrial kilns and produces RDF of different types and classes.

Co-processing of Food Waste and MSW/Kitchen Waste
1)Co-processing makes full use of the features and advantages of bio-hydrolysis system and resolves problems of further treatment and utilization of solids occurred in food waste treatment.
2)Process is simplified, reducing project investment and project space.

4. EMBT Cases
1)Hangzhou Environmental Group EMBT Demonstration Project
