What Is Size Reduction?

Size reduction is one of the most important stages within any recycling process. Before materials can be washed, separated, dried or reprocessed, they must first be reduced to a consistent size that allows downstream equipment to operate efficiently.
Modern size reduction equipment enables recyclers to transform bulky waste materials into manageable feedstock, improving material handling, increasing throughput and enhancing overall plant performance.
For recycling facilities processing plastics, industrial packaging, drums, IBCs and production scrap, effective size reduction can significantly reduce operating costs while increasing the value of the finished recycled product.
Why Is Size Reduction Important?
The primary purpose of size reduction is to create a consistent material size suitable for further processing.
Without effective size reduction, recycling plants can experience:
โข Material handling problems
โข Reduced washing performance
โข Lower separation efficiency
โข Increased downtime
โข Higher energy consumption
โข Reduced throughput
By implementing the correct size reduction equipment, operators can optimise the entire recycling process.
Types of Size Reduction Equipment

Industrial Shredders
Industrial shredders provide primary size reduction by breaking large materials into smaller pieces. They are commonly used for plastic drums, IBC containers, purgings and bulky waste materials.
Granulators
Granulators provide secondary size reduction and create a more uniform particle size suitable for washing and reprocessing applications.

Integrated Size Reduction Systems
Integrated systems combine shredding, conveying, granulation and material handling into a single automated solution, maximising efficiency while reducing manual intervention.
