Feedstocks

The Stein Gasifier can use a variety of fuels and the fuel supply does not need to be homogeneous.

Fuel diversity leads to flexibility and sustainability.

The fuel has to be shredded to a size less than 15mm, so that the fuel can be fed into the system with almost no oxygen in it.
The process can also take fuels with a high moisture content. Greater efficiency is obtained by reducing the moisture content to between 5-10%, through utilizing waste heat generated by the gasifier.

Fuels include (individually or mixed):

• Biomass from timber and crops (either specifically grown for the process, or waste from existing industries)
• Abattoir and food processing waste
• Sewage sludge (animal slurries and urban wastes)
• Municipal solid waste (MSW), and miscellaneous, pre-sorted industrial waste
• Bio-fuels
• Plastics
• Peat
• Coal and lignite (coal and peat)
• Clinical waste
• Commercial and industrial waste
• Tyres
• Lubricants
