Solid state polycondensation is the final step that transforms recycled PET into a food-ready polymer For that to happen, though, the SSP process needs to be carefully controlled within exact engineering limits Learn the essentials of the process here –…

In any plastic recycling washing line, only one metric determines the market value of your output flakes: whether or not the target polymer floats in the liquid phase. Float-sink separation-or sink-float separation, also sometimes known as density-based sorting-is the most…

Plastic types do not fit on one shelf. Some can bend, some can shatter, some melt at 110C, some can survive a pot of 250C. Some leave nothing but fresh bottles after a single pass on the wash line; some…

Quick Reference: Thermosetting Plastics at a Glance Global production Over 65 million tonnes/year Share of all polymer output ~18% of global polymer production Typical cure temperature 80–200°C (varies by resin system) Max continuous service temp 150–300°C (phenolic and polyimide grades)…

High density polyethylene recycling has shifted from an eco-friendly sustainability buzzword to a real industrial supply chain for recycling plastics at scale. As of 2025, US recycled HDPE prices are at parity with virgin in some grades, the world mechanical…

Ocean recycling refers to collecting plastic before it enters the ocean (by intercepting it on the coast, placing barriers in the rivers, or removing plastics from the ocean with clean-up operations) and transforming it into re-usable pellets at a pelletizer…

A compostable container looks like the obvious sustainable choice ne×t to a recyclable plastic clamshell or a disposable PET deli container. Label promises return-to-earth disposal; material is plant-based; marketing copy writes itself. Then the container gets to a US municipal…

Recyclable plastic bottles – a very soft sub-category – think recycle them in blue bin, walk away, the job is done. Reality lives in the bottom equilateral triangle: a number that reveals to a sorting machine, a buyer and a…

This plastic shredder maintenance program guides recycling-plant operators, maintenance engineers and equipment buyers through the 4 moves that decide if a single-shaft or twin-shaft shredder machine makes its 10-year service life or limps to 3 – blade rotation by material…

The honest answer to “what does an industrial plastic shredder cost” is wider than most buyers expect: a small 200 kg/h single-shaft model can ship for about $8,000, while a 5,000 kg/h quad-shaft system built to shred plastic tires or…
