Baler statistics impress

presona lp65 baler in action at ecogen

Ecogen Recycling is a fast-grow­ing recycling company. Through­put is increasing by 10% month-on-month, so it was clear that new plant was needed to maintain momentum.

With the focus placed firmly on expansion, the team specified a Presona LP65 VH K2 cross-tie baler to increase material processing speeds and bale density, adding an essential degree of future-proofing to the business.

The baler has increased the company’s processing capacity from eight tonnes to 22 tonnes an hour, an improvement which will enable it to become more compet­itive when it comes to commercial waste purchasing.

Ecogen bought its first Presona baler when it moved to Alresford, Hampshire, two years ago. The LP50 prepress baler was used to bale cardboard, paper, plastic and shredded paper. It was reliable and worked well – it still does, but the firm always had an eye on increasing throughput speeds to allow it to grow on this site.

The team started to look for a new baler which would increase throughput and bale density, and the LP65’s vital statistics were impressive. Ecogen wanted the baler to deliver improved compac­tion rates, provide increased cross-ties to accommodate densely packed plastic film and perform faster throughput rates.

The original baler produced a standard bale weight of 350- 400kg with plastic film. The new LP65 has increased this by 35% to an average of 550kg. In fact, the company processed a bale of cup­cake skeletal waste at 860kg and the average cardboard bale is now 600-700kg. Ecogen is now run­ning tests to see just how far it can increase its bale tonnage.

Based on an average 500kg plastic bale, Ecogen has increased its container rate from 18-20 tonnes to 24 tonnes, cutting logis­tics costs and making the whole process more profitable.

In addition, it is now able to process material much faster, which is critical because it oper­ates on a small site. It processes up to 20 containers of cardboard a week.

Initially, the plan was to trade in the old LP50 prepress baler, but the team was reluctant to let it go because it had many years of operation left. So with the help of Presona’s engineering team, the LP50 will be moved to a different building where it will become part of a paper and shredding line.


Founded in 2010 by managing director William Nicholls, Ecogen regularly processes up to 3,000 tonnes of paper, card and plastic a month, all from commercial sources. It takes post-manufacturing material from customers located across the UK, working with organisations in a range of sectors including automotive and food packaging.

It also works with waste management companies of all sizes and often processes, aggregates and trades material from smaller organisations to optimise quality and maximise value. In addition, Ecogen provides a shredding service.
