Envelope Recycling 101: What Businesses Need to Know About Disposal and Recovery

We may live in a digital age, with most of our communication sent via devices, but many of us, and companies in particular, still send and receive notices the old-fashioned way: through the mail. And when you get a lot of stuff in the mail, often you end up with a lot of envelopes. Responsible businesses that aim to be eco-friendly are usually very good about not just tossing them in the trash, but getting them into a recycling bin. The problem, however, is that disposing of them isn’t always that simple. In fact, envelope recycling can be surprisingly complicated. Here, we explain why this is the case and what your business can do to maximize its recycling efforts, even when inundated with envelopes.

Why can’t envelopes be recycled with regular paper?

Most envelopes are made of paper, and if this is their sole material, recycling them isn’t typically a problem. The trouble comes when they are made with different elements. Often, these include plastic windows, various adhesives, or colored stock. When these things get into your bales, it spoils the quality. This contamination results in lost rebate dollars and unnecessary disposal costs. Below, we explore the complexities of envelope recycling and how 4G’s envelope recycling expertise can help you capture more value.

Why envelope waste is challenging

Chances are, you have an envelope within arm’s reach right now. Grab it and take a good look. It may seem like it is just made of regular paper, but it could actually be composed of a specialty material like Tyvek or Duraguard. It might contain coated layers, wax, or another type of adhesive, along with a plastic window. These may seem inconsequential, but they need to be taken into consideration when it comes to recycling.

Best practices for envelope recycling

How can your business ensure it maximizes the use of recyclable materials? The key is to put a clear strategy in place, which should involve these five steps: 

1. Separate by envelope type and material

As mentioned, envelopes can vary widely in the materials they are made of. This is why they need to be correctly separated: sorting plastic-window envelopes, coated or dyed papers, and colored and specialty stocks from white uncoated envelopes.

2. Remove or process windows correctly

Some Material Recovery Facilities (MRFs) or partner mills require that plastic film be removed, and in this case, it must be removed manually or mechanically.

3. Manage cuttings and production scrap

Once scrap is created, it can’t be casually discarded. It too needs to be sorted, this time by substrate, thickness, and adhesive load. It also needs to be identified as originating from RA/AMC presses rather than other processes.

4. Use proper equipment and staging

Using the right equipment is paramount for ensuring that everything is done correctly. This should include:

• Color-coded carts to prevent cross-stream contamination
• Baling or compacting equipment suited for light papers and mixed densities
• Shredders for security envelopes or sensitive mail

5. Quality audits and contamination checks

Regular inspections are a final crucial step in the envelope recycling process. To track adhesives or film contamination, random bale inspections are essential. 4G’s rigorous reporting system makes it easy to track rejects or downgrades. 

This may seem like a lot of work, but it will be worth it when you: 

• Get cleaner bales that give you a higher rebate value
• Have less risk of bale rejection or downgrades
• Capture value from specialty scraps instead of discarding
• Foster greater alignment with your sustainability goals

Is your business ready to improve its envelope recycling?

Every envelope your business handles that ends up in the trash or is improperly mixed with other materials costs you money and harms your sustainability efforts. Answer these questions to determine if an envelope recycling program is right for you:

• Do you generate envelope waste with plastic windows, colored stock, coatings, or other materials?
• Do you fabricate envelopes, i.e., produce cuttings or trimmings?
• Are your bales or recycled paper streams being downgraded or contaminated?
• Do you lack visibility into how your envelope scrap is being handled or valued?
