What happens to all the plastic waste after it leaves a factory or a recycling bin? Many people don’t really know what “recycling” means. They just leave it there, and then it changes into something else. But in the background, things are much more complex, technical, and interesting.

Plastic garbage doesn’t just become useful raw materials. By carefully following steps like grinding, shredding, and toll processing, we can give old plastics a new life. AP&J Recycling doesn’t just pick up trash; they also help businesses use fewer landfills, protect the environment, and keep important resources in circulation.

In this article, we’ll talk about what really happens behind the scenes during these processes, why they are important, and how they fit into the bigger picture of creating a circular economy.

Why recycling plastic is more important than ever

Plastic is used to make a lot of things, such as packaging, car parts, medical equipment, and things we use every day. Plastic is tough and useful, but it has one big problem: it doesn’t break down when you throw it away. If you don’t take care of it, it can stay in landfills for hundreds of years.

This is why recycling is so important. Manufacturers want to do more than just follow the rules and keep the environment safe. They also want to save money and do their jobs better. When you recycle correctly, waste from making things can be turned into feedstock that can be used again. This means we need less new plastic, and it’s cheaper to throw things away. Grinding, shredding, and toll processing are the first steps to making that happen.

Grinding: Taking Plastics Apart

Grinding is the process of breaking up larger pieces of plastic, like scrap, offcuts, or broken things, into smaller, more even pieces called regrind. It’s like taking apart an old plastic bin and melting it down so you can use it again.

Why It’s Important to Grind

• Molding machines can only work with things that are all the same size.
• Smaller pieces melt more evenly and are more reliable, which makes them work better.
• Cost Savings: By turning scrap into regrind that can be used, businesses save money on raw materials.

Example in Action

Think of a factory that makes large plastic boxes. There will always be parts that don’t work or are broken. They are not thrown away; instead, they are ground up, cleaned, and put back into the process. Now, something that could have gone to the dump is useful.

Shredding is the first step for plastics that are hard to work with.

Shredding is usually the first step when working with big or oddly shaped materials. Making consistent regrind is what grinding is all about. Shredders can break down anything, even big molded pieces, plastic pipes, and pallets.

How to Shred

• The material is broken down into smaller pieces by a rotating drum or blades.
• The size of the shredded output can change depending on how it is used.
• People often grind the shredded stuff to make it all the same size.

Why You Should Shred

• Handles a lot of trash: Some things are just too big for a grinder to handle.
• Getting ready to process:It’s easier to clean, sort, or grind plastic that has been shredded.
• More safety: Things are less likely to hurt you if you break them up before you touch them.

The first step is shredding, and the second step is grinding, which makes the work more accurate. They work together to make it possible to recycle things that would be very hard to throw away otherwise.

Toll Processing: Custom Recycling Services for Companies

Some businesses don’t have the space, tools, or know-how to recycle their own plastic trash. That’s when toll processing is useful.

What is the process for paying a toll?

Companies that do toll processing, like AP&J Recycling, pick up materials from customers, turn them into regrind or pellets, and then give the finished product back. The client still owns the material the whole time.

Why Businesses Use Toll Processing

• Keeps the material’s value: Customers are in charge of their own plastic scrap, so they can make sure it comes back ready to use.
• You can change the method to work with plastic that is different types, sizes, or levels of cleanliness.
• A professional can handle recycling while companies focus on making things.

A real-life example

Every month, a company might throw away thousands of pounds of polypropylene. They don’t throw it away; instead, they pay AP&J Recycling to process it. 

FAQ’s

Q: What kinds of plastic can be ground or shredded?

Most post-industrial plastics, like polypropylene (PP), polyethylene (PE), polystyrene (PS), and others, can be processed by grinding and shredding.

Q: What is the difference between pellets and regrind?

Plastic that has been broken up into small pieces or flakes is called regrind. After more work, pellets are usually the same size and ready to use when performance is important.

Q: Can small businesses use toll processing?

Yes. Not just big companies use toll processing. Companies that make plastic waste every day can use it again if they send it to a processing plant and get it back.

Q: How does toll processing help us reach our sustainability goals?

It cuts down on trash, saves money on landfills, and makes sure that useful materials are put back into the process of making things. This helps companies follow the rules for the environment.
