FAQs

Is the SPS technology well proven? 

The SPS uses a process called pyrolysis. This entails heating materials to a high temperature in the absence of oxygen.
 The technology has been used since ancient times for the production of charcoal and is still used for charcoal production now. It is only recently that the technology has been used for processing waste because of the compelling economic case but it is now becoming established for this application.

What materials is the SPS able to process? 

The SPS can process a wide range of waste materials including municipal (household) waste – also known as MSW, commercial & industrial waste, refuse derived fuel (RDF), plastics, tyres, wood waste, green waste, sewage sludge and many hazardous wastes. It is possible to blend several of these waste types and process them together.

Bio waste (hay, straw, leaves, wood, animal dropping, etc.)

Automotive and Chemical industry (tires, plastics, carpets, rubber)

Municipal solid waste (household waste-excluding steel, glass, construction waste)

Plastic waste (waste from plastic production, plastic waste)

Sludge (waste from water treatment plants)

Coal dust

Hazardous waste (hospital waste)


What waste quantities can be handled? 

The standard SPS module process 1 tonne of waste per hour but modules can be produced to process up to 6 tonnes per hour. The modular construction means that any quantities can be processed using multiple units.

How is energy produced? 

The pyrolysis process produces synthetic gas (syngas) which is a mixture of hydrogen, methane, nitrogen and several other gases. Syngas has a calorific value of around half that of natural gas. The syngas is first cleaned to remove tar and oils and is then fed to a gas engine or gas turbine linked to an electrical generator. A 1 tonne per hour module will produce between 1 MW and 2MW of electrical output depending on feedstock. Alternatively, by adjusting the process temperature, the SPS can produce synthetic, low sulphur diesel fuel that can be used in vehicles.
The SPS also produces significant quantities of high temperature heat. This can be used for drying applications (e.g. wet wastes), producing steam or heating buildings or greenhouses.

What about emissions from the process? 

The SPS was developed in California and meets all requirements of the South Coast Air Quality Management District (SCAQMD) – the strictest in the world. Tests on plants installed in the EU show that the SPS meets all requirements of the Waste Incineration Directive (WID).

What are the outcomes of the waste processing?

 These are energy (syngas, fuel and heat that can be truneed into electricity) and by-products (carbon black, bio-char and clean whater). You can further read about these questions in technology secction.

What is te timing of delivery of one standard machine?

Time for delivery: from 4 to 6 months.

Time of making it run: 2-3 months after delivery.


How many people is needed to run the module?

1 leader ( 8 hours per day) – administration ( Mo – Fri )
1-2 operator ( per each 8 hours ) ( Su – Sa )
1 operator – electrician ( per each 8 hours ) ( Su – Sa )

This is an estimation based on how already working modules perform.


Type of manteinences of the module on yearly bases and time that the machine will stop its work for the manteinences

We are calculating operation time min. 8000 hour / year.  Remainder time is for maintenance, holiday, … Standard maintenance time is apr. 10-14 days / year.


Is finance available? 

Several sources of finance are potentially available. Please reach us for more information on this subject trhough our contact secction.
