Sterimelt is an on-site thermal processing system designed to consolidate suitable polypropylene (PP) waste into dense, manageable blocks. By processing material where it is generated, Sterimelt helps organisations reduce storage requirements, simplify waste streams, and prepare recoverable plastic for onward recycling.

Suitable polypropylene materials are segregated and loaded into the machine, where they undergo a controlled thermal processing cycle. The process consolidates the loose, bulky material into a dense block, significantly reducing its volume and making it easier to store, handle, and transport.

Sterimelt forms part of the recycling process. Rather than producing finished recycled products, the machine consolidates suitable waste plastic into a more manageable material for collection and onward reprocessing.The resulting material can then be processed by specialist recyclers and potentially used in the manufacture of new plastic products.

Conventional compactors generally compress waste mechanically, meaning the material may expand again once the pressure is removed.Sterimelt uses controlled thermal processing to consolidate suitable plastics into a denser, more stable form. This can provide advantages for long-term storage, transportation and subsequent material recovery.

Each system is designed for different material streams and operational requirements.Sterimelt focuses on suitable polypropylene materials, including selected healthcare and industrial applications.Massmelt is designed for larger-scale thermal compaction of heterogeneous waste streams, subject to material assessment.Curtainmelt is a specialist solution developed for suitable synthetic disposable hospital curtains.Our team can advise which system is appropriate based on your materials, volumes and site requirements.
