With the development of the photovoltaic industry, the number of waste photovoltaic modules is also increasing. How to dispose of these waste components has become an urgent problem to be solved. In order to meet the requirements of harmlessness, recycling, and environmental protection, it is necessary to adopt certain technologies that meet the market process to treat waste photovoltaic modules.
First of all, harmless treatment is the basic requirement for the treatment of waste photovoltaic modules. Since photovoltaic modules contain some harmful substances, such as glass, silica gel, backsheets, etc., these substances can cause harm to the environment and human health if not handled properly. Therefore, when dealing with waste photovoltaic modules, these harmful substances need to be separated and treated to ensure that they do not cause harm to the environment and human health.
Secondly, resource utilization is an important direction for the disposal of waste photovoltaic modules. The main materials in photovoltaic modules are resources such as silicon and copper, which are limited in reserves on the earth, so effective measures need to be taken for ** and reuse. Resources such as silicon and copper from used PV modules can be separated and extracted physically and chemically, and then these resources can be used to produce new PV modules or other useful products.
Environmental protection is the basic requirement for the disposal of waste photovoltaic modules. When dealing with waste PV modules, it is necessary to reduce the pollution and damage to the environment as much as possible. Some environmentally friendly technologies and equipment can be used to deal with waste photovoltaic modules, such as biodegradation technology, solar energy technology, etc. These technologies and equipment can effectively reduce pollution and damage to the environment, and at the same time, they can also reuse useful resources from waste photovoltaic modules.
In order to achieve the requirements of harmlessness, recycling, and environmental protection, it is necessary to adopt stable and feasible technologies to treat waste photovoltaic modules. At present, some advanced technologies have been studied and applied, such as physical crushing, water mill separation method, and pyrolysis method. These technologies can effectively separate and dispose of harmful substances and useful resources in used PV modules, while also reducing pollution and damage to the environment.
In the physical shredding method, waste photovoltaic modules can be broken into small pieces, and then harmful substances such as glass, silica gel, backsheet and useful resources can be separated and disposed of through screening and sorting. The advantages of this method are that it is simple to operate and low cost, but the separation effect does not produce secondary pollution.
To sum up, the treatment of waste photovoltaic modules requires the adoption of environmentally friendly technologies to meet the requirements of harmlessness, resource utilization and environmental protection. Although some treatment technologies are available, further research and innovation are needed to explore more efficient, environmentally friendly and safe treatment methods. At the same time, it is also necessary to strengthen the development and reuse of photovoltaic modules to promote the sustainable development of the photovoltaic industry.
