About Southern X Press Ltd
History
Through the 1980s/90s, I was a drought prone grassland farmer in North Otago, I recognised the futility in sustainable pasture management.
The main issue was pasture surplus to deficit management. Either way, these extremes are massive, both are equally debilitating to grassland Net Primary Productivity (NPP). I saw a problem with the pasture harvesting techniques for which I developed a hydraulic press. At the time, the obstacles to bringing that up to a realistic field operation was just too demanding and here is my observation subsequent to that time.
given my current pressing experience, I can now see ways around previous difficulties so I look forward to returning to this development in due course. I’ll be back!!!
Who could have predicted that revisiting grassland perspectives would include a proposal for ZG/ID@SE.
In 2001, I started using the prototype press for baling paper, cardboard and plastic while I worked with JM Davie Ltd, Dunedin to build on a more commercially viable mobile baling unit for a wide range of bulk material which got on the road in 2003. After a fire at Christchurch City’s kerbside paper recycler in 2005 SXP baled over half the City’s newsprint while maintaining a service for the Dunedin kerbside news print collection and service to Alexandra and Oamaru.
SXP also has experience in developing separation process / techniques of modest scale for a commercial paper / glass / plastic / can collection.
Since 2008,SXP has specialised in recycling End Of Life Tyres. Based in Bromley, SXP have processed over 30,000 Tonnes of tyres.
In recent times, SXP has cleared some large tyre stockpiles as well as packing agricultural and horticultural plastics for Plasback, working in Waikato, Bay of Plenty, New Plymouth, Hawke Bay, Nelson, Marlborough and Central Otago as well as site cleanups in and around Christchurch.
The Custom Mobile baler can pack over 6 Tonnes of tyres per hour into 2 tonne bales. These bales are exported to India, where those are granulated into a product for use in road construction, playing fields and in reconstituted rubber products to meet European Environmental specifications.
For 15 years, there has been a priority on developing better outcomes for end of life tyres. That has now become a more complex proposal for atmospheric carbon accumulation.

Like everyone else who has gone down the pyrolysis pathway, we quickly found out all the pyrolysis process problems that have frustrated all those who have gone before us. Gasification is a much shorter process pathway and is old technology. Germany had much of its homeland fleet powered by gas producers through World War 2. However, we can now achieve that without releasing smoke.
- Complete combustion is more readily achievable with a gas, than as a solid or liquid fuel.
- Low temperature gasification is a thermo chemical process that does not burn the biomass fixed carbon, making the residual carbon very resistant to environmental degrade. It will not become atmospheric with a half life of hundreds of years.
- Humanity is now in the predicament where we need all the tools in our tool box for atmospheric carbon accumulation including carbonisation of waste biomass which will result in a residual product that cannot be called biochar. SXP has adopted the term Pyrolytic Carbonisation expressed as PyC to describe the process and the residual product
The commercial drivers to do this are less than compelling?
SXP History
In 2001, I started baling cardboard and clear plastic in a mobile press that I had initially developed for use in the agricultural industry back in the mid 1990s. At the time, the obstacles to bringing that up to a realistic field operation was just too demanding but given my current pressing experience, I can now see ways around previous difficulties so I look forward to returning to this development in due course. I’ll be back!!!

SXP Current Position
Southern X Press Limited is currently baling and exporting plastic and End of Life tyres but is developing a gasification technique which produces energy in the form of hot water and steam.
The baling technique produces neat, high density, 2 Tonne bales ideal for handling and transport. More importantly, increased density and good bale shape are critical to scaling up the energy technique. The bales need no further preparation for a continuous feed to the gas producer. Gasification is a relatively simple technology where the product gas is taken straight to combustion which overcomes the technical issues that have frustrated many that have gone before us.
Technical support comes from the team leaders of Solid Energy’s successful underground coal gasification project. This development program is being funded from the support of the loyal customers of Southern X Press Limited.
