Net Zero Waste
Net Zero Cost.

Recycling end-of-life, unused, or broken solar panels in Missouri—including in cities like Kansas City, Columbia, St. Louis, and Springfield—offers numerous benefits:

1. Environmental Responsibility

Solar panels contain hazardous materials such as cadmium, chromium, and lead. Improper disposal can lead to these substances polluting waterways and landfills. Recycling ensures these materials are safely managed, protecting the environment from harm.

2. Conservation of Resources

Manufacturing solar panels requires valuable materials like silicon, glass, silver, and copper. Recycling recovers these resources, reducing the need for new extraction. This conservation effort helps preserve non-renewable resources and reduces manufacturing costs.

3. Reuse of Recycled Materials

Recovered materials from recycled solar panels can be used to create new products, including new solar panels. This sustainable practice decreases the environmental impact and supports a circular economy by minimizing the need for raw material extraction.

Recycling your solar panels in Missouri is not only an eco-friendly choice but also a practical way to conserve resources and reduce waste, contributing to a more sustainable future.

Recycling solar panels in Missouri involves several steps, each designed to recover valuable materials while ensuring environmentally safe disposal. Here’s an outline of the process:

1. Dismantling

The initial step is to dismantle the panels by separating their components:

• Glass, metal, and plastic parts are removed.
• Plastic components are more challenging to extract compared to glass and metal.

2. Hazardous Materials Removal

Solar panels may contain hazardous materials such as chromium, lead, and cadmium.

• These substances are carefully extracted and disposed of safely, using methods like incineration, shredding, or secure landfilling to prevent environmental harm.

3. Glass Recycling

The glass extracted from solar panels is crushed into smaller pieces, melted, and reshaped into:

• Bottles
• Windows
• New solar panels or other products

4. Metal Recycling

Metal materials such as silver and copper are melted at high temperatures and repurposed into:

• Cars
• Computer hardware
• Other metal-based products

5. Plastic Recycling

Plastic components are melted down and molded into new items, including:

• Toys
• Furniture
• Other plastic goods

Why It Matters
While each step can be complex, recycling solar panels in Missouri significantly reduces waste, conserves valuable resources, and protects the environment. This process transforms end-of-life solar panels into raw materials for new products, promoting sustainability.

Most solar panels can be recycled in Missouri, but some may require specialized handling due to the presence of hazardous materials. Here’s an overview of the major types of solar panels and their recyclability:

1. Crystalline Silicon Solar Panels

• Description: The most common and widely used solar panel type, made primarily of silicon.
• Recyclability:
  • Relatively easy to recycle.
  • The process recovers a high amount of reusable materials, including silicon, glass, and metals, which can be used to make new solar panels or other products.

2. Cadmium Telluride Solar Panels (CdTe)

• Description: A thin-film solar panel made from cadmium and telluride, both hazardous materials.
• Recyclability:
  • Requires special tools and handling to ensure safe disposal of hazardous components.

3. Thin-Film Solar Panels

• Description: A broad category of solar panels made from various materials, such as cadmium telluride, copper indium gallium selenide (CIGS), and amorphous silicon.
• Recyclability:
  • Most thin-film panels can be recycled, but the complexity depends on the materials used.

4. Amorphous Silicon Solar Panels

• Description: Made from non-crystalline silicon, these panels are less efficient and more affordable than crystalline silicon panels.
• Recyclability:
  • Lower recyclability rates compared to crystalline silicon panels.

5. Copper Indium Gallium Selenide (CIGS) Solar Panels

• Description: Thin-film panels made from copper, indium, gallium, and selenide.
• Recyclability:
  • Can be recycled, but the process is still evolving as these panels are relatively new to the market.

6. Perovskite Solar Panels

• Description: A cutting-edge solar technology made from perovskite, a mineral known for its high efficiency in converting sunlight into electricity.
• Recyclability:
  • While recyclable, the rate and process are still under evaluation due to their novelty.

While most solar panels can be recycled in Missouri, the ease of recycling and recovery rates vary depending on the panel type and materials. Panels with hazardous materials require specialized care, underscoring the importance of working with a qualified recycling facility.

Yes, solar panel recycling in Missouri is environmentally friendly and can contribute to a more sustainable future in several ways:

Reducing Pollution
Solar panels contain hazardous materials that, if not recycled properly, can harm the environment. Proper recycling ensures these substances are safely disposed of, preventing pollution and protecting ecosystems.

Conserving Valuable Resources
Solar panels are made with renewable and valuable materials like silicon, copper, and silver. Recycling these components reduces the need for mining new resources, helping conserve natural materials for future use.

Creating Job Opportunities
The solar panel recycling industry in Missouri is expanding, creating jobs in collection, processing, and manufacturing. This growth supports the economy while fostering sustainability.

In conclusion, recycling solar panels in Missouri is a sustainable and recommended way to manage their end-of-life, benefiting both the environment and the local economy.

The materials from recycled solar panels in Missouri are often repurposed to create new electronic devices, including new solar panels, or are used in other industries. Some materials may also re-enter circulation for broader use. Here’s a breakdown of the most common materials and their new purposes:

Glass
Recycled glass can be used to manufacture items like bottles, jugs, windows, and various other products.

Metal
Metals such as silver and copper are repurposed to create cars, computer hardware, and a range of metal appliances.

Plastic
Plastic components can be melted down and re-molded to produce toys, plastic furniture, and other plastic-based products.

Semiconductors
Recovered semiconductors can be utilized to develop new electronic devices, including solar cells and solar panels.

Other Components
Adhesives and sealants from solar panels are often repurposed in the production of new items.

For materials that cannot be reused, they are disposed of responsibly to minimize environmental harm. Hazardous materials are handled and discarded safely to protect both recyclers and the environment.
