How do you handle waste food Packing Box
1. Pretreatment technology
Food Packing Box waste pretreatment refers to the use of physical, chemical or biological methods, the Packing Box waste into a convenient transport, storage, recycling disposal of the form. Pretreatment often involves the separation and concentration of certain components in the waste of the Packing Box, and is therefore often a process for the recovery of the material. Pretreatment techniques are mainly sorted, compacted, broken and dehydrated.
The sorting of the waste of the Packing Box is to separate the various useful resources in a manual or mechanical manner, reclaimed and used in different productions.
Packing Box The compaction of waste is an operational technique that reduces the apparent volume and improves transport and management efficiency. Compaction technology is more common in foreign countries, China is only used in limited areas.
The crushing process of the Packing Box waste is a process that reduces its individual size and makes it uniform in texture, thereby reducing voids and increasing bulk density.
The dewatering problem of the waste of the Packing Box is generally used for the mixing of the waste in the municipal waste and the sludge with large water content. In order to separate the useful waste of the Packing Box, it is necessary to carry out the dehydration reduction in order to separate And transport.
Drying is mainly used for Packing Box waste after crushing, sorting the light material, the use of such light materials for energy recovery or incineration treatment need to dry, in order to achieve the purpose of water, weight loss.
2. Chemical treatment technology
There are many types of waste in the Packing Box, and many of the contents of the Packing Box are harmful chemicals, and are often left in the Packing Box waste after use. Chemical treatment is a chemical reaction to the Packing Box of waste harmful substances into a safe and stable material, so that the harm to the waste to the lowest possible level, is a harmless treatment technology.
3. Incineration technology
Incineration is the use of high-temperature thermal decomposition method, the oxidation of the Packing Box to become a small bag of waste, the harm to the environment of small substances. Packing Box waste can be burned, the volume can generally be reduced by 80% -90%; some of the harmful substances in the Packing Box through the incineration, can damage its organizational structure or kill pathogens, to detoxification, the purpose of detoxification. Incineration method developed rapidly in developed countries, has formed a complete set of processing technology and systems equipment. The advantage is that the heat released by the combustion of waste can be used. It is generally estimated that incineration of 1 kg (after sorting) after Packing Box waste can produce 0.5 kg of steam and its full utilization will be a lot of resources The
4. Pyrolysis technology
Because there are many organic compounds in the Packing Box material, with thermal instability, therefore, when placed in the anaerobic or anoxic high temperature conditions, under the combined action of decomposition and condensation, this kind of organic matter will crack, transformation For the smaller molecular weight gaseous, liquid and solid components. Pyrolysis technology is the use of organic Packing Box waste this feature, in the high temperature anaerobic or hypoxic conditions for a harmless treatment of a method.
Pyrolysis and incineration are completely different from the two processes. Incineration exotherm, you can recycle this part of the heat, and pyrolysis is endothermic. The products of incineration are mainly carbon dioxide and water, and the product of pyrolysis is mainly combustible low molecular compound: gaseous hydrogen, methane, carbon monoxide, liquid methanol, acetone, acetic acid, acetaldehyde and other organic matter and tar Oil, etc., the main solid state is coke or carbon black, these products can be recycled.
5. Microbial decomposition technology
Microbial decomposition technology refers to the use of the widespread distribution of microorganisms in nature, through biotransformation of the Packing Box waste easily biodegradable organic components into humic fertilizers, biogas or other chemical conversion products, such as feed protein, ethanol or sugar Class, so as to achieve a harmless Packing Box waste disposal method. The biggest advantage of this technology is the ability to recycle the final product to achieve the resource utilization of the Packing Box waste, is a promising method.
