Case Studies

These examples of TORBED processor installation illustrate the durability, control and versatility that our technology offers, operating at temperatures from 140°C to 1400°C.

Sappi Maastricht

Installed in 2002, this multistage TORBED drier is used to dry 6 tonnes per hour of paper sludge from 60% moisture to 5% moisture. Replacing a belt drier used for the same purpose, the TORBED achieved greater availability and reduced cost by avoiding maintenance needs and being capable of remote operation. The dried paper sludge is used as animal bedding, ensuring that a waste that would otherwise rot and create carbon emissions is put to use.


Commercial Pilot Plant

Shown here in mid-assembly, this plant embraces the circular economy, drying paper sludge and calcining it, providing heat both for industrial purposes and to dry the sludge.

The ash from the calcination is a useful cementitious mineral capable of use as a cement substitute in concrete. This is a practical example of Torftech’s technology being used to de-carbonise a foundation industry.


Imerys Par

A flash calciner, exfoliating clay to make ingredients for white paint dye, this TORBED processor operates at 1400°C, using gas injection to create intense process conditions.

Gas Scrubbing

Using alumina as a reactant to scrub hydrofluoric acid from gas streams exhausted Aluminium smelters. 19 of these giant 6 metre TORBED processors, installed in 1996 and 1997 in Australia and New Zealand, remain in operation despite dealing with both a highly abrasive reactant and a corrosive gas stream.


Coffee Roasting

Slow Roast Flavour - Fast.

Roasting with a TORWAVE offers many benefits to coffee roasters. Combining conventional hot air heating with microwave power offers total control over the roasting process. It is also an intense process, with time reductions of up to 80% compared to conventional roasting, without any of the downsides of traditional fast roasting.

The TORWAVE also unlocks new possibilities for coffee flavour and extraction with increased bean surface area. This is all done in a fully electric system, displacing any requirement for gas burners.

TORWAVE roasting is a green solution to get more out of your beans.

More Flavour

TORWAVE roasting happens throughout the whole of the bean simultaneously, allowing flavour development without overprocessing the outside or under-processing the inside.

Higher Surface Area

The high intensity heat transfer in the TORWAVE leads to increased bloating and porosity of the coffee beans, increasing surface area by up to 20%.

Superior Control

Independent control of hot air and microwave power lets roasters precisely control the roast conditions and be flexible to get the most out of any bean

Fully Electric

The TORWAVE processor can provide all of these benefits with a fully electrical system, allowing a move away from traditional gas fired roasters, reducing CO2 emissions.
