Q: What is your product?
A dual tying head for twin-ram balers, developed by Middleton Engineering, combines wire tie and plastic strapping capabilities on the same machine. This offers greater flexibility and cost savings to operators.
Q: How does it work?
The tying head can be rotated quickly to allow either method of tying, enabling the same baler to be used for normal recyclables using wire ties or for RDF/SRF where plastic strapping is more appropriate.
Q: Where would it be used?
Councils and waste management operators working with multiple waste streams, or intending to extend their operation to process refuse-derived fuel waste. The head can be retrofitted for practically any make of horizontal baler currently in use.
Q: How is it different?
Middletons believe this is the first dual tying system manufactured in the UK, and the easiest system to use.
Q: What are the benefits?
Operators can change from one tying head to the next in minutes. This is especially useful for small- to medium- size operators who might not be able to justify the expense of an additional baler to accommodate different waste materials.
The ability to use plastic strapping, made from recycled PET, offers significant costs savings over steel ties. Up to 40% cheaper than wire, it is also environmentally friendly and fully combustible, making it ideal for energy-from-waste applications.
Q: Where has it been used?
The tying head is a new system, shown for the first time at RWM in September.
It evolved from Middleton’s design work with a plastic strapping system currently being piloted at Biffa’s Dewsbury plant in Yorkshire.
Middleton has already had significant interest in this technology from waste firms in the UK and Norway.
The system is available either as part of a new baler or as retrofit upgrade to an existing machine. Price depends on specifications, including baler type and machine size.
Q: What about maintenance?
With a simple daily and weekly checklist, basic maintenance can be carried out safely by operators, and takes only a few minutes.
Maintenance services are tailor-made, with an agreed level of support based on how hard a machine is worked.
Q: What is its lifespan?
With regular maintenance and servicing, Middleton expects the system to last as long as the baler itself.
