Recycle Insulation Components
The superior dielectric and mechanical properties of ceramic and thermoset materials make them popular in the electrical industry. They are ideal for insulation, bushings and instrument transformers. An appropriate waste management policy must therefore ideally be available in relation to reutilization/recycling of scrapped components. For example, the Polish legislation is based upon European Directives. It has stated that waste management development should focus on those wastes that comply with these requirements.
* can be used in a production process as a raw material.
* can be used to replace fuel or raw material that has been used in the production process.
* can be used for improving the quality and efficiency of a production line;
* can be used in order to reduce the hazardous effects of the process on our environment
* can be used to source valuable materials
* After processing, a valuable product can be created
Due to the growing volumes of scrap materials and the limited amount of landfill space available for their disposal, it will be necessary to promote more advanced recycling technologies. These options were considered in the past when it came to thermoset wastes.
* Application as construction materials
* energy recovery;
It has been suggested that epoxy-based scrap can be used in asphalt or concrete construction materials. However, the economic benefits of this solution are very low due to the small quantities and geographical distribution of waste streams. Epoxy scrap is used extensively in electrical equipment, and consequently various internal parts made from metals (e.g. cores, windings, etc.) The epoxy contains cores, windings, and other components. Pre-treatment is required for scrap. This includes removing metallic parts and crushing. Energy recovery through combustion is a viable option due to the high energy content in thermosets (LHV ranging from 10 to 20MJ/kg depending upon filler content). These treatments can produce large quantities of inorganic matter, such as filler, and should be managed economically. The combustion of thermosets can be considered safe from an air pollution perspective, provided that the process is well defined and hazardous emissions are limited. Degradation is another option. This refers to the reduction of plastics into lower molecular weight materials by means such as photo-degradation chemical degradation and biodegradation. Pyrolysis, a particular form of chemical degradation, is the focus of this research on thermoset scrap utilization.
Scrap Ceramic Insulators
The problem of utilizing scrap porcelain insulators is not being well-known. You can use scrap porcelain insulators for road aggregate, ice melting and outdoor tiling. Sometimes used porcelain insulators can sometimes be re-utilized by their manufacturer to make new insulators. These insulators are often stored at substations and sometimes without disposal or simply buried.
It is obvious that the development of a more flexible technology and the implementation of a waste management strategy that efficiently manages large quantities of porcelain insulators have become a necessity. This led to the need for a new solution.
Proposed Recycling Solution For Thermosets
The insulation material often contains valuable metal components like copper and aluminum, so any recycling solution for thermoset-based parts such as epoxies or silicones must take this into account. Any proposed method must produce high-quality recycled parts. Pyrolysis was chosen as a method of utilization due to its ability to thermally degrade in an oxygen-free environment. This allows for a variety of end products. :
* Pyrolytic gas
* liquid products;
* solids (char, mineral fillers, metals).
Laboratory investigations have confirmed that there are technologies for recycling different types insulation components. However, these technologies cannot be commercialized without waste disposal companies implementing appropriate policies to collect these components efficiently. Local governments are also required to support this process.
